This 18-Year-Old's Invention Could Make Your Future Phone Instacharge

While you are hanging out on the Internet (in your underwear, maybe?) on a Saturday, kids that are smarter than either of us are out there getting ready to change the world. 18-year-old Eesha Khare (left), for instance, not only invented a supercapacitor that could someday be a phone battery that charges in just a couple of seconds; she also won $50,000 for it. Khare is one of the three big winners from the Intel International Science and Engineering Fair. She and 17-year-old Henry Lin (right)—who created a model that simulates thousands of galaxies—picked up Intel Foundation Young Scientist Awards. Meanwhile, 19-year-old Ionut Budisteanu won the Gordon E. Moore Award and $75,000 for his AI model that could lead to a cheaper self-driving car. Khare's invention is the one with some really immediate potential though, and quick-charging phones is something we all want. So far, the supercapcitor has only been tested to light up a LED, but it was able to do that wonderfully and the prototypes new format holds potential to be scaled. It's also flexible and tiny, and should be able to handle 10,000 recharge cycles, more than normal batteries by a factor of 10. It's a great step in the right direction, especially since we all know that battery life is the most important feature a phone can have. But like all supercapcitor tech, it's not exactly close to commercial development yet. But hey, if an (admittedly super smart) 18-year-old can get this stuff figured out, multi-national corporations with an even bigger cash profit incentive on the table should be able to as well, right? Hurry up already. I'll take either solution so long as one comes soon.

What do you do if the power is out, but you need to charge your cell phone to make an emergency phone call? In this episode of DIY Hacks & How To’s, I show you how to tap the power flowing from your phone line.

There is a small amount of electricity that is constantly available in a phone line. This is what powers traditional corded phones. Because the phone system is independent of the power grid, the phone line generally even has power during a black out. While this is not a lot of power, it is enough to charge your small electronics such as your cell phone or other USB device. All you need is a simple voltage regulator circuit.

High Capacity Backup Battery Will Keep You Powered For a Week

High Capacity Backup Battery Will Keep You Powered For a Week

Until all of our electronic devices are powered by tiny Mr. Fusions, backup batteries are a harsh reality. But with a massive 9900mAh battery, the hard drive-sized iGeek should power all of your gear for up to a week.

A lot of back batteries don't have enough kick to charge power-hungry devices like the iPad, but with one and two amp USB ports, the iGeek will happily top off your tablet andyour iPhone at the same time. In fact, you'll be hard pressed to find a mobile device it can't recharge, short of laptops, Segways and electric cars.

The $62 battery promises up to fifty additional hours of movie time with your iPhone, iPod Touch or media player of choice, and up to seventeen additional hours with the iPad 2. Next to a comfy pair of shoes and a steady supply of Red Bulls, it's the perfect accessory for tackling conventions, trade shows and exhibitions.
