Although you may not be able to cancel your electrical service for you home just yet with this simple project you will be able to harvest ambient light from anywhere and store it into a battery that can then be used any other purpose. More after the jump….

A low-power, sensor system developed at the University of Michigan 1,000 times smaller than comparable commercial counterparts. It could enable new biomedical implants.

Earth, air, metal and water make light. This earth battery produces 12V and was an experiment on increasing the amps with only a serial series and strong electrolyte. Next step is to make smaller and find the right parallel/serial series to produce grunt.

I wanted to find a motion led light that would provide more then enough light for moving around the house after dark but was not able to find one that did not cost and arm and a leg. So, I decided to build my own using off the shelf parts.

K. I. S. S. I. N. G.

I always hated when kids used to say that to me….

Anyway, today I decided to take an old linksys wireless router and see if I could leach off the public library as the signal to my house was so faint that usually one could not login to the public hotspot provided by them. I soon was able to do just that.

Researchers at the Cornell University have taken inspiration from nature and tried to imitate the swaying of tree branches. So what is the difference between natural swaying of trees and energy-harvesting tree created by Cornell University researchers? The flapping leaves developed in the laboratory generate energy which can be used by us.

Just when we thought tree only provided shade in the heat of the sun and the little detail of providing oxygen, we now learn that tree actually produce electrical energy. While it is true that you are not going to be able to cancel the electrical companies service just yet, there is enough available to power a remote sensor.

Nigel Chivers decided to get himself a solar powered radio. In looking at the local retail outlet he was put off by both the price of the cheap units as well as the fact that they had the wind up crank. He did not feel like winding a handle all day long just to listen to the radio. He did however need something that would work out in the middle of nowhere, and work all day long.

Here is what he came up with. An old radio that he made solar powered by using parts from a junk garden lamp. Cheap, and best of all no cranking at all! Yea.

You can checkout his build via the link below.

Louis LeGrand has always loved the new drones (aka; uav) so one day he decided to build his own solar powered airplane. This thing aint gonna be droppin' anything as it's far too light but hay you have to start somewhere right?

Very nice build Louis! Thanks for sharing it.

Personally I hate doing laundry. That was part of the reason I got married;-) Anyway, you eco nuts out there will love this earth friendly solar powered washing machine developed by a French student. Kinda gives a whole new meaning to the phrase "sunshine fresh" don't it? DIY instructions and details at the link below.

For those of you that may have missed it please see part one of the Solar Powered DIY HotSpot.

I recently built another one of these little units that can be taken literally anywhere. By mounting the entire setup into a portable backpack this can be taken anywhere and not stand out so much. Well, maybe;-)

Our favorite astronomer has updated his page today to include some new video showing how to create your very own wind turbine on the cheap using a treadmill motor and some homemade parts you may already have laying around the house or yard. For those of you that are very mechanically challenged so not worry, he includes step by step his directions for how he did it.

Ever wondered what it would be like to have your own hotspot no matter where you went? Well now you can with this portable solar powered Wi-Fi repeater.

Have you ever wanted to build your own solar powered webcam? Sometimes you are not always going to have the grid available to you or sometimes it would simply be far too expensive to use the grid. With this DIY system anyone should be able to run a webcam no matter where they are.

What could be better then playing a cool new game on your Nintendo DS? How about being able to it without ever having to worry about finding an outlet to charge the batteries.
