Back in 2009, we did go over the Oyster Wave Energy Converter, here’s another good candidate for converting ocean waves into energy.
Imagine this, earth is made up mostly of water and even if we utilized a small number of the raw power from waves, we could essentially power the whole earth! The only problem? The cost to make these wave energy converters. At first, it’s going to be billions of dollars but in the long run wave energy could be powering everything at cost of almost
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.
You probably well know of the focus that the world has been giving to alternative energy. And I am sure schools are now pushing more ways to power our electronics than ever.
Which brings us to this awesome DIY that shows you how to build a salt-water powered LED light. You can also substitute lime juice for the salt-water.

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
Previously we had several different blog posts on how to make a DIY wind turbine:
How to Make Wooden DIY Vertical Wind Turbine!
Here’s another great site that details every step of the way so you can build yourself a DIY vertical wind turbine.
With a coil, couple miniature magnets and an LED, did you know that you can make your own self-sustaining DIY LED flashlight?
I know, it’s mind boggling that you can build one yourself and it’s so simple. Now, please add a circuit so it will “charge” a re-chargeable lithium battery, that will make it puuuurfect.
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:
You might remember the “water-powered” batteries from Japan about a year back. Well, if you thought that was innovative, check out Brother’s new invention, vibration-powered double-A batteries that can be used for low-voltage gadgets.
I know for a fact that this would work really well for kid’s toys where shaking often occurs anyways, this could be ground-breaking, saving a whole lot of energy worldwide when it debuts.
This time, Brother Industries prototyped the genera
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”.
