Do you have an eReader such as a Kobo or a Kindle that you read often under the sunlight, perhaps at the beach on your smoke breaks?
If so, you might be interested in turning some of that UV rays into charging your eReader as one user did with his Kobo eReader, attaching a 80mA output solar cells to the back of the unit.
Although most eReaders do have good battery life but this could be a good application to refer if you have similar projects.
5 years ago, it was a lot harder to build your own solar-charging systems but now there are so much more resources plus price of solar systems have dropped quite a bit. If you own a home and you have some space in your backyard (or roof) for solar panels, there’s absolutely no reason why you aren’t powering some of your home electronics via the power of the sun (unless you live in Alaska and it’s no-sun season).
Here’s a great example of a DIY portable solar charging system
Well, today is that day folks, it’s called Earth Day and you know what?
It’s time for the most eco-friendly and green gadgets of 2011!
Solar LED Desk Lamp – I work right by a big window that gets a lot of sunlight. This Solar LED Desk Lamp will definitely cut your desktop electric bill to near zero because it can be fully-recharged and provides 5 hours of light.
Best of all, it comes with a 12-feet outdoor-rat
I’ve been meaning to get a USB solar charger/battery pack but luckily, MiniInTheBox.com sent me one for a review couple weeks back. Anyways, this thing is pretty awesome, it basically re-charges itself when there’s even any hint of light.
How powerful is it? It’s rated at 2600mAh, meaning you can probably re-charge your iPhone/Android smartphone/Blackberry twice fully.
Besides that, it also comes with an AC adapter s
For those of you living like a scumbag and never recycle, here’s some of the best eco green posts to help you get out of it:
Tuk Tuk, basically a bicycle that can transport passengers, is probably the most popular transportation in Thailand and many parts of South America.
Well, here’s an innovative idea, a “solar” Tuk Tuk, that can provide the driver with some extra “oomph”.

For those of you looking for alternative solar energy that you can actually use for re-charging/powering your gadgets and whatnot, you might want to take a look at this guide that a college engineering student made during his experience of making a custom solar panel for his latest project.
Currently I’m a college student studying computer engineering, and this summer while I was on break I decided I wanted to learn more about solar energy and how to build a solar panel from scratch. My main
Natural disasters have caused a ton of damage to home owners, businesses, and even the government. For floods, the Department of Natural Resources of Australia and Penguin Labs have devised a DIY flood-triggered automated camera system that would takeimages of a cave flood (when it floods) in order to study the water flow and how it affects the environment. Mainly, a “water switch” is used to detect water in the device with solar power to keep the device charged with power.
A water flow gauging station was onc
For those of you eco-enthusiasts out there (like me), you might be happy to learn that ReNu solar-powered iPhone/iPod speakers will be available so you can enjoy your favorite music without adding to the world’s carbon footprint but by using solar power! You can pre-order yours on Amazon here for $149.
The best part about these new ReNu speakers is that they can even “recharge” your iPod or iPhone using the po
