Can you imagine charging your cellphone without plugging it into an outlet? No, I’m not talking about those plug and charge kits you can purchase for select phones, I’m talking about fuel cell stickers. Just slap ‘em on the back of your phone and considered it charged.

The Swedish-based company myFC is trying to expedite the act of charging cellphones by creating this alternative eco-friendly method. It’s a flexible .11 inch thick, .2 ounce charger that provides .9 watts of power at .5 volts. While it might not be as nifty as a jacket that charges your gadgets, it’s certainly more convenient. Slap one on your face and see what happens.

It’s the middle of July and that means those of us in the Northern Hemisphere are really feeling the heat. With my current apartment, I have no air conditioning in my bedroom and during the day it becomes unbearable at times when temps start reaching the 90s. I need a way to cool off.

Thankfully, Instructables user Farhanians has posted instructions for a DIY air conditioning system that is not only efficient, it’s portable to boot. So now you have no excuse to be walking around your crib naked. Put on some pants, buy the parts and make the AC happen.

For those that live in places where the climate does not allow you to live without an air-conditioner, you will understand how annoying it is to clean the filters inside. We all aim to clean it at least once a year, but sometimes it is up till the point when we can’t stand the smell any more do we take turns to do the cleaning. Sanyo’s new Seasonal Color air-conditioner EX series have a few gadgets in their to save your trouble. There is UV that kills the germs, there’s Ozone that reacts with whatever that gives out smell, there’s also a CO2 and air quality sensor in there that once activated can suck out the air indoors and replace it with filtered clean ait from the outside. With that, we probably would have never needed to wash our air-conditioners for the rest of our lives. These machines will come out in March, selling at $2.3K in Japan. — Sam Chan
