I sure loves me some sun jars!  They incorporate several of my favorite things to mess around with:  LEDs, Solar panels, hot glue, man it’s all there and they look great to boot!

Here are step-by-step instructions on how to build your own!

You have most likely heard of a potato battery, a lemon battery, an earth battery. Well here we present a plant battery powered LED light.

Back in the late 1800′s almost all of the telegraphs in the United States and Europe ran off “Earth Batteries” Here we take a fresh new look at the earth battery and how you can use this free energy to power your small electrical gadgets.

A mud battery is made with a zinc or graphite anode (the positive terminal), buried in mud, and a cathode (negative terminal) in the seawater, both connected by a copper wire. Here we take a look at how your backyard could supply you with energy to light your garden.

A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.

Last year I found a United States Patent that showed how to collect ambient energy right from the air. I finally decided to build this curcuit just to see what it could do.

Here is a neat little project idea. I recently picked up a cheap china made desktop weather, clock, humidity unit. I found that if I attached one cheap solar panel from a junk garden lamp this thing would stay running just from the lights in the room sitting on my desktop.

A very powerful vawt I built in my basement out of some commonly used parts.
