67 Science-Backed Ways to Lose Weight -Part-2

11. Deep Freeze
Once meal prep is over, serve yourself a reasonable portion, then package up the rest and stash it in the fridge or freezer for a later date. When the food is out of sight, studies show you’ll be less likely to reach for a second helping [10] [18].

12. Wait before grabbing seconds
The quicker we shovel down a meal, the less time we give our bodies to register fullness [19]. Since it takes about 20 minutes for the brain to get the message that dinner’s been served, it’s best to go for a walk or play cards before dishing up seconds or tackling the dessert table.

13. Snack before dining
Grabbing an apple or a small cup of yogurt before meeting friends for dinner can help ensure you’ll eat a reasonable amount of that enormous entrée (rather than overdo it). And be sure to reach for the protein — research shows that an afternoon snack of Greek yogurt can lead to reduced hunger, increased fullness, and less eating come dinner time [20].

14. Turn off the tube
Eating while watching television is linked to poor food choices and overeating [21]. Getting sucked into the latest episode of Snooki and JWoww can bring on mindless eating and it can be easy to lose track of just how many chips we’ve just thrown down the hatch. It’s not just the mindlessness of watching televsion that’ll get us. Commercials for unhealthy foods and drinks may increase our desire for low-nutrient junk, fast food, and sugary beverages.

15. Turn your back on temptation
The closer we’re situated to a food that’s in our line of vision, chances are the more we’ll actually eat of it [22]. If we face away from food that might tempt us when we’re not all that hungry (like an office candy bowl), we may be more likely to listen to cues from our gut rather than our eyes.

16. Hands off
When snack time hits, our brains can be pretty unreliable. It’s tempting to reach for a bag of chips, but instead, grab a handful (or measure out the serving size) then seal the bag up and put it away. Odds are, you’ll be more mindful of how much you’re polishing off when you see it right in front of you. And next time there’s a between-meal tummy rumble, try one of these healthy, satisfying 100-calorie snacks.

17. Pack the protein
Protein can help promote a healthy weight because high protein diets are associated with greater satiety, plus it’s important for healthy muscle growth [23]. Animal sources aren’t the only option — try alternatives like quinoa, tempeh, and lentils.

18. Fill up on fiber
Eating more vegetables and other high-fiber items like legumes can help keep us fuller, longer [24] [25]. Look for at least five grams or more of the stuff per serving. Snack on some of our favorite high-fiber picks like stuffed baked apples or jazzed up oats.

19. Make room for (healthy) fats
Cutting butter and oil can slash calories, and it’s easy to swap in foods like applesauce, avocado, banana, or flax for baking. But, it's important to remember that we still need fat in our diets as a source of energy and to absorb the fat-soluble vitamins A, D, E, and K. Plus it helps us feel full.  Get healthy monounsaturated and polyunsaturated fats from avocadoes, olive oil, nuts, coconuts, seeds, and fish [26]. Bonus tip: Combining fat with fiber has been shown to increase fat’s power to make us feel full [27].

20. Steer clear of simple carbs
Simple carbs are the white stuff — white bread, most pastries, refined sugars (like in soda). What makes it so simple? These foods provide energy, but lack the same  nutrients (vitamins, minerals, and fiber) as complex carbohydrates [28]. The body also breaks simple carbs down quickly, spikes blood sugar (insulin), and leaves your tummy might rumbling sooner than you imagined [29]. Choose whole grains instead, which may reduce potentially dangerous excess abdominal fat buildup (which can lead to diabetes) [30]. Switch to whole-wheat pasta or whole grain bread, or try grains like brown rice, quinoa, or millet.

21. Sneak in the veggies
Bumping up vegetable consumption has long been recognized as a way to protect against obesity [31]. Add veggies to an omelet to cut down on cheese, use them in baked goods, and pasta dishes (Bonus: Try zucchini ribbons, or spaghetti squash instead). Pump pureed veggies, like pumpkin, into oatmeal or casseroles. Adding a little vegetable action into a meal or snack will increase fiber levels, which helps make us fuller, faster [32].

22. Ditch added sugar
A spoonful of sugar allegedly helps the medicine go down, but adding it to food may increase the risk for cardiovascular disease and obesity [33] [34]. Stick to sugar that comes in its natural form (in fruits, veggies, and whole grains) and scrap that morning-coffee-spoonful [35].

23. Make subs
No, we don’t mean the sandwich. We mean easy recipe substitutions. Simple swaps — like Greek yogurt for sour cream, prunes for butter, or an Americano for a latte — can cut calories and sugar. Even a grilled cheese can get a healthy revamp by making a few smart subs.

24. Cook smart
Even healthy food can become not so great when it’s been dropped into a fryer. Instead, pan fry or pop a dish in the oven. Use non-stick spray to sauté foods, or rub oil onto a pan with a paper towel for a light coating. You can even whip up a batch of healthier chips.

25. Heat it up with cayenne
Cayenne pepper, the bright red spice, can not only boost metabolism, but can also cut cravings for fatty, sweet, or salty foods [36] [37]. Some studies even suggest that the hot stuff can increase fat oxidation, meaning the body can better use fat as fuel [38] [39]. Sprinkle some on scrambled eggs, or spice up a stir-fry with a little hot sauce.

26. Chew gum
Popping a piece of sugar free gum won’t necessarily curb your appetite. But, chewing a 5-calorie stick can keep the mouth busy when cooking up a meal, or socializing amongst a sea of hor d’ouevres at a party. While the long term effects of gum chewing on weight loss are minimal, studies show it can lower cravings for sweet and salty snacks, and decrease hunger between meals [40] [41].

27. Go straw-less
... with fruit, that is. Juices (which are often far from 100 percent fruit) provide some vitamins, but without the same fiber and phytonutrients as a real piece of fruit. Let’s take an apple for instance. An 8-oz. glass of apple juice has double the sugar and less than one-tenth the fiber of a medium apple.

28. Cave in to cravings
We love this tip. Cravings are OK! Acknowledge those cravings instead of pushing them away completely (which may lead to blowing it later). Caving into a craving, as long as it’s in moderation (try on of these healthier ways to satisfy a sweet tooth) can actually help curb desire. Forbidding a food may only make it more attractive. Still want more of that chocolate cake after a couple of bites? Try thinking of your favorite activity — dancing in the rain, getting a massage, playing with a puppy. Research shows that engaging in imagery can reduce the intensity of food cravings [42].

29. Bag it up
Sometimes we’d rather not admit it, but let’s face it — restaurant meal portions are generally heftier than what we cook at home [8]. Make a conscious decision to bag up half of the meal before taking the first bite. The added benefit? You’ve got a doggie-bag lunch for tomorrow!

67 Science-Backed Ways to Lose Weight -Part-1

Healthy habits can quickly go out the window when we’ve got a tight deadline, no time for the gym, and few options but take-out food. Losing weight is no easy task, and doing it the healthy way can be even harder. We’re advocates for making small changes each day, rather than making drastic changes all at once. But it’s important to remember that just because a weight-loss strategy works for some (even if it’s backed by scientific studies) it may not work for everyone. From drinking more water to eating from blue plates, we’ve rounded up some of our favorite weight-loss tips to add to your daily routine.


Disclaimer: This article is not meant to be a comprehensive weight loss guide. Each entry may not be right for every individual. We at Greatist believe in providing readers with the information to make their own healthy choices based on a variety of weight loss techniques. What's appropriate for one person may not be best for his or her friend, mom, cousin, etc. As always, consult with a healthcare professional before starting any weight loss program. 

1. Get the blues
“I got the blues” may conjure up memories of those macaroni and cheese commercials from the ‘90s, but we’re talking about blue dishware. The color blue can act as an appetite suppressant because it has the least appealing contrast to most food. Research says to avoid plates that match the food served on them (like white plates and fettuccini Alfredo), because there is less of a contrast, which may prompt us to eat more. A small but potentially useful trick!

2. Eat snacks!
Skipping out on snack time won’t necessarily lead to weight loss, since low calorie consumption can actually slow metabolism [1]. Eating less than three times a day may benefit those who are obese, but research shows skipping meals throughout the day and eating one large meal at night can lead to some undesirable outcomes (like delayed insulin response) which may increase the risk of diabetes [2] [3]. Instead of forgoing breakfast or lunch, stick to a few meals a day with healthy snacks in between.

3. Peruse the perimeter
Next time you need groceries, circle the perimeter of the store before going in. This isn’t a way to stalk out your prey, but actually a tactic to load up on the healthy stuff first. The edges of grocery stores generally house fresh produce, meat, and fish, while the inner aisles hold more pre-packaged, processed foods. Browsing the perimeter can help control how many unwanted additives are in the grocery basket.

4. Stock the fridge
Make an effort to fill the fridge with healthy produce and proteins (from perusing the perimeter!). Keep lots of fresh fruit and veggies on hand. And for when the fruit basket goes barren, make sure the freezer is stocked with frozen veggie mixes or berries (grab the bags full of just veggies, not the ones with butter-laden sauces). You may be less apt to order out when you’ve got the makings of a healthy dinner right at home. And the good news is, healthy food doesn’t always have to be pricey.

5. Eat in the A.M.
Skipping breakfast in order to “save your appetite” for dinner probably isn’t a safety shield for late-night noshing [4]. While there’s still debate on how important breakfast really is, not eating until the afternoon may lead to binging later on (ie. four servings of mashed potatoes) [5]. Make sure to stick a reasonably sized breakfast with plenty of protein; we tend to eat the same sized lunch and dinner regardless of how many calories we eat in the morning [6].

6. Get busy in the kitchen
We promise cooking doesn't take long! Restaurants often use larger plates than the ones we have at home, and studies show that increased portion sizes result in increased energy intake, even if there’s a doggy bag involved [7] [8] [9]. Why not start by making these healthy meals in just 12 minutes or less (quesadillas, stir-fry, and burgers, oh my!).

7. Prioritize the pantry
Take a little time out to toss the junk. If you’ve got some favorite not-so-great items you’d like to save as a treat, tuck them in the back of the pantry with healthier items, like whole grain pasta, rice, beans, and nuts up front. We know that just because the cans of tuna and a bag of lentils are right in front doesn’t mean you’ll forget the brownie mix altogether, but it’ll help keep the brownie mix out of sight, out of mind. Just seeing or smelling food can stimulate cravings, and increase hunger (especially true for junk food) [10].

8. Serve "restaurant" style
Instead of lining up the breadbasket, entire casserole, and salad bowl, right on the table, leave food on the kitchen counter (away from reach). When you’ve cleaned your plate, take a breather then decide if you really want those seconds. Changing up the environment, like by leaving food by the stove, can help reduce food intake [11].

9. Use smaller plates
History shows plate sizes have increased over the past millennium [12]. When it’s time to sit down for dinner, choose a size-appropriate plate or bowl. Using a smaller plate (8-10 inches) instead of a tray-like plate (12 inches or more) can make us feel fuller with the same amount of food. How does this magic trick work? The brain may associate the white space with less food, plus smaller plates generally lead to smaller portions [13].

10. Chew slowly
Eating slowly may not fit into a busy workday, but it pays to pace your chewing: the quicker we eat, the less time the body has to register fullness [14] [15] [16]. So slow down, and take a second to savor.

Oceanlinx : 1MW wave converter


Oceanlinx, a wave energy developer in Australia, has set out to harness the ocean waves in the belief that their enormous quantities of energy can be transformed into a real solution. The concept involves the use of waves to produce high pressure air, which in turn is converted into electricity by a turbine.





What Happens to Your body if you stop smoking Right now?



I think one of the main reasons it’s so hard to quit smoking is because all the benefits of quitting and all the dangers of continuing seem very far away. Well, here’s a little timeline about some of the more immediate effects of quitting smoking and how that will affect your body RIGHT NOW.

* In 20 minutes your blood pressure will drop back down to normal.


* In 8 hours the carbon monoxide (a toxic gas) levels in your blood stream will drop by half, and oxygen levels will return to normal.


* In 48 hours your chance of having a heart attack will have decreased. All nicotine will have left your body. Your sense of taste and smell will return to a normal level.


* In 72 hours your bronchial tubes will relax, and your energy levels will increase.


* In 2 weeks your circulation will increase, and it will continue to improve for the next 10 weeks.


* In three to nine months coughs, wheezing and breathing problems will dissipate as your lung capacity improves by 10%.


* In 1 year your risk of having a heart attack will have dropped by half.


* In 5 years your risk of having a stroke returns to that of a non-smoker.


* In 10 years your risk of lung cancer will have returned to that of a non-smoker.


* In 15 years your risk of heart attack will have returned to that of a non-smoker.

So, you have more immediate things to look forward to if you quit now besides just freaking out about not being able to smoke. Quit now!

Top 10 Things You Can Upgrade with a Little Electronics Hacking

Rule #1 of DIY: Never settle for what you're given. You can upgrade and improve just about anything with a little knowledge and elbow grease, especially if you know a little about electronics. Here are 10 things in your home that you can beef up with a little soldering and DIY know-how.

10. Your TV

 
You may have the coolest home theater on the block, but even that won't save you when your TV rebels with the latest celebrity gossip you don't want to hear. Take control of your TV with the Enough Already, a little DIY gadget that mutes your TV whenever it hears a word or phrase you've programmed it to watch out for—like "Justin Beiber" or "Twilight Saga." While you're at it, you can use an Arduino to automatically lower the volume if it gets above a certain threshold, like when excessively loud commercials come on.


9. Your Home Security

 
 

It may not be as foolproof as a true home security system, but you can make quite a few DIY burglar alarms for almost nothing. $2 gets you a tiny motion alarm that beeps if its moved, while a few more dollars will get you a motion-detecting camera or an SMS-equipped monitor. Heck, you can even build your own LoJack for your car at a fraction of the price. Of course, you can also do quite a bit with just a few webcams and some free software.

 

8. Your Desk

  If your workspace is starting to feel a little cluttered with gadgets, make them work with your desk. Instead of getting another power strip, build an outlet into the desk itself, or embed a USB hub for easy charging and peripheral connection. If you want to take it one step farther, you can add an inductive charging station or even build a computer inside the desk drawer. And, while you're at it, clean everything up by making your desk lamp cordless for under $20.

 

7. Your Video Game Consoles

 What's better than having a couple of video game systems in your living room? Not much, except maybe combining them into one mega system that can play nearly any game. If you're more of a retro gamer, you can do something similar (with much less work) by building an all-in-one retro gaming console inside an NES, inside a briefcase, or even inside a coffee table to mimic the old arcade systems you love so much.

 

6. Your Cellphone Charger

 If you want a really easy DIY project, try upgrading your wall outlets to charge USB devices. You can also build a super-simple portable USB charger in an Altoids tin. For a greener solution, make it solar-powered or charge it with the power of your bike pedaling. And, if you want to do away with wires altogether, we've shared a ton of options for modding your phone for wireless charging without the bulky "induction charger" case.

 

5. Your Transportation

Many of us may upgrade our phones every year to stay up-to-date, but it's a little harder to do that with cars. If your car's missing a feature you want, though, just add it yourself. Put in an auxiliary audio jack for only $3, or add Bluetooth capability for wireless streaming wherever you go. If you're prone to running red lights, you might also consider this GPS hack that warns you when red light cameras are near. And, if you don't have a car, you can still beef up your transportation with these bike upgrades.

 

4. Your Headphones

 We love headphone hacks, and if you're willing to dig into your DIY arsenal, you can mod the hardware in quite a few ways. If you have earbuds, you can add an inline remote control with just a little bit of work (and without ruining them). If you have a bigger set of headphones, adding removable cables can be really handy, or you could go wireless altogether and hack them for Bluetooth. Of course, a good pair of earmuffs can also make for a dandy noise-isolating pair of headphones, too.

 

3. Your Light Switches

Turning on the lights manually is no fun. Instead, mod the lamps in your house to turn on with a wave of your hand, or with an old-school made-at-home clapper. Alternatively, control them with your voice, or set them up in the hallway for easy motion-controlled lights that illuminate your path to the bathroom. Whatever you can think of, it's probably possible.

 

2. Your Chores

Doing chores is for chumps. Luckily, an Arduino and a bit of code can automate a ton of chores for you: it can make the plants water themselves, it can feed the cat for you, or even rock your baby to sleep. Just make sure your parents/spouse/roommates don't find out what you're up to.

 

1. Your Home

 

A home of the future isn't as far off as science fiction makes it out to be. With a little DIY electronics hacking, you can automate your home to do just about anything: open the blinds when it's light, tell you who's at the door, make you coffee with a tweet, unlock your door with a text message, and oh-so-much more. It won't get you George Jetson's flying car, but you'll feel like a futuristic badass nonetheless.

18 Health Tricks to Teach Your Body

Eating 10 hot dogs in 6 minutes and belching the national anthem may impress your friends, but neither of those feats will do much for your body—at least not much good.
Instead, why not train yourself to do something that may actually pay off?

We're not talking bench presses and interval training (though those do help). You can teach your body to cure itself from everyday health ailments—side stitches, first-date jitters, even hands that have fallen asleep.

Just study this list, and the next time your friends challenge you to an ice cream eating contest, chow down: You know how to thaw a brain freeze—and 17 other tricks that'll make everyone think you're the next David Blaine. But without all that "hold your breath for 17 minutes" mess.



Cure a Tickling Throat

When you were 9, playing your armpit was a cool trick. Now, as an adult, you can still appreciate a good body-based feat, especially if it serves as a health remedy. Take that tickle in your throat: It's not worth gagging over. Here's a better way to scratch your itch: Scratch your ear. "When the nerves in the ear are stimulated, it creates a reflex in the throat that can cause a muscle spasm," says Scott Schaffer, M.D., president of an ear, nose, and throat specialty center in Gibbsboro, New Jersey. "This spasm relieves the tickle."


Experience Supersonic Hearing

If you're stuck chatting up a mumbler at a cocktail party, lean in with your right ear. It's better than your left at following the rapid rhythms of speech, according to researchers at the UCLA David Geffen School of Medicine. If, on the other hand, you're trying to identify that song playing softly in the elevator, turn your left ear toward the sound. The left ear is better at picking up music tones.


Overcome Your Most Primal Urge

Need to pee? No bathroom nearby? Fantasize about Jessica Simpson. Thinking about sex preoccupies your brain, so you won't feel as much discomfort, says Larry Lipshultz, M.D., chief of male reproductive medicine at the Baylor College of Medicine. For best results, try Simpson's "These Boots Are Made for Walking" video.


Feel No Pain

German researchers have discovered that coughing during an injection can lessen the pain of the needle stick. According to Taras Usichenko, author of a study on the phenomenon, the trick causes a sudden, temporary rise in pressure in the chest and spinal canal, inhibiting the pain-conducting structures of the spinal cord.


Clear Your Stuffed Nose

Forget Sudafed. Here's an easier, quicker, and cheaper remedy to relieve sinus pressure: Alternate thrusting your tongue against the roof of your mouth, then pressing between your eyebrows with one finger. This causes the vomer bone, which runs through the nasal passages to the mouth, to rock back and forth, says Lisa DeStefano, D.O., an assistant professor at the Michigan State University college of osteopathic medicine. The motion loosens congestion; after 20 seconds, you'll feel your sinuses start to drain.


Fight Fire Without Water

Worried those wings will repeat on you tonight? Try this preventive remedy: "Sleep on your left side," says Anthony A. Starpoli, M.D., a New York City gastroenterologist and assistant professor of medicine at New York Medical College. Studies have shown that patients who sleep on their left sides are less likely to suffer from acid reflux. The esophagus and stomach connect at an angle. When you sleep on your right, the stomach is higher than the esophagus, allowing food and stomach acid to slide up your throat. When you're on your left, the stomach is lower than the esophagus, so gravity's in your favor.


Cure Your Toothache

Just rub ice on the back of your hand, on the V-shaped webbed area between your thumb and index finger. A Canadian study found that this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of the brain that blocks pain signals from the face and hands.


Make Burns Disappear

When you accidentally singe your finger on the stove, clean the skin and apply light pressure with the finger pads of your unmarred hand. Ice will relieve your pain more quickly, Dr. DeStefano says, but since the natual method brings the burned skin back to a normal temperature, the skin is less likely to blister.


Stop the World from Spinning

One too many drinks left you dizzy? Ah, luckily there's a remedy. Put your hand on something stable. The part of your ear responsible for balance—the cupula—floats in a fluid of the same density as blood. "As alcohol dilutes blood in the cupula, the cupula becomes less dense and rises," says Dr. Schaffer. This confuses your brain. The tactile input from a stable object gives the brain a second opinion, and you feel more in balance. Because the nerves in the hand are so sensitive, this works better than the conventional foot-on-the-floor wisdom.


Unstitch Your Side

If you're like most people, when you run, you exhale as your right foot hits the ground. This puts downward pressure on your liver (which lives on your right side), which then tugs at the diaphragm and creates a side stitch, according to The Doctors Book of Home Remedies for Men. The fix: Exhale as your left foot strikes the ground.


Stanch Blood with One Finger

Pinching your nose and leaning back is a great way to stop a nosebleed—if you don't mind choking on your own O positive. A more civil approach: Put some cotton on your upper gums—just behind that small dent below your nose—and press against it, hard. "Most bleeds come from the front of the septum, the cartilage wall that divides the nose," says Peter Desmarais, M.D., an ear, nose, and throat specialist at Entabeni Hospital, in Durban, South Africa. "Pressing here helps stop them."


Make Your Heart Stand Still

Trying to quell first-date jitters? Blow on your thumb. The vagus nerve, which governs heart rate, can be controlled through breathing, says Ben Abo, an emergency medical-services specialist at the University of Pittsburgh. It'll get your heart rate back to normal.


Thaw Your Brain

Too much Chipwich too fast will freeze the brains of lesser men. As for you, press your tongue flat against the roof of your mouth, covering as much as you can. "Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too," says Abo. "In compensating, it overheats, causing an ice-cream headache." The more pressure you apply to the roof of your mouth, the faster your headache will subside.


Prevent Near-Sightedness

Poor distance vision is rarely caused by genetics, says Anne Barber, O.D., an optometrist in Tacoma, Washington. "It's usually caused by near-point stress." In other words, staring at your computer screen for too long. So flex your way to 20/20 vision. Every few hours during the day, close your eyes, tense your body, take a deep breath, and, after a few seconds, release your breath and muscles at the same time. Tightening and releasing muscles such as the biceps and glutes can trick involuntary muscles—like the eyes—into relaxing as well.


Wake the Dead

If your hand falls asleep while you're driving or sitting in an odd position, rock your head from side to side. It'll painlessly banish your pins and needles in less than a minute, says Dr. DeStefano. A tingly hand or arm is often the result of compression in the bundle of nerves in your neck; loosening your neck muscles releases the pressure. Compressed nerves lower in the body govern the feet, so don't let your sleeping dogs lie. Stand up and walk around.


Impress Your Friends

Next time you're at a party, try this trick: Have a person hold one arm straight out to the side, palm down, and instruct him to maintain this position. Then place two fingers on his wrist and push down. He'll resist. Now have him put one foot on a surface that's a half inch higher (a few magazines) and repeat. This time his arm will cave like the French. By misaligning his hips, you've offset his spine, says Rachel Cosgrove, C.S.C.S., co-owner of Results Fitness, in Santa Clarita, California. Your brain senses that the spine is vulnerable, so it shuts down the body's ability to resist.


Breathe Underwater

If you're dying to retrieve that quarter from the bottom of the pool, take several short breaths first—essentially, hyperventilate. When you're underwater, it's not a lack of oxygen that makes you desperate for a breath; it's the buildup of carbon dioxide, which makes your blood acidic, which signals your brain that somethin' ain't right. "When you hyperventilate, the influx of oxygen lowers blood acidity," says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. "This tricks your brain into thinking it has more oxygen." It'll buy you up to 10 seconds.



Read Minds

Your own! "If you're giving a speech the next day, review it before falling asleep," says Candi Heimgartner, an instructor of biological sciences at the University of Idaho. Since most memory consolidation happens during sleep, anything you read right before bed is more likely to be encoded as long-term memory.

Charge your smartphones with Wi-Fi.

Allen Hawkes and Alexander Katko from Duke University's Pratt School have figured out a way to charge your smartphones  with  Wi-Fi.

They have developed a device with metamaterials that captures energy waves from wireless Internet and converts them into electrical current.


The device can wirelessly convert Wi-Fi’s microwave signals into direct current voltage to recharge a cell phone battery or other small electronic devices. Key to this power harvester are the metamaterials, which are engineered structures that can capture various forms of wave energy and tune them for useful applications. These energy sources could include satellite signals, sound signals or Wi-Fi signals.

PhotoFlow: Solar Photovoltaic Device and Rainwater Harvester

A design company called NOS has developed a solution to two major problems facing developing countries: scarcity of drinking water and electricity. The concept is called the PhotoFlow, a combination solar photovoltaic device and rainwater harvester.

The PhotoFlow is made up of eight identical triangular photovoltaic panels that are mounted on a 400-liter recycled polyethylene water tank. The panels form an octagon with a slope of 3 degrees that allows water to funnel into the central filter and be collected into the tank. To keep the water potable once it's collected, the inner layer of the tank is covered with a coating that controls levels of bacteria and fungi.

The solar panels, which are capable of generating 340 kWh of electricity, are covered with an antireflective adhesive which helps prevent loss of light through reflection as well as a nano layer of dirt-repelling film to keep the panels clean and working at maximum output.
