This is probably one of the more interesting projects I’ve seen in a while, at least conceptually. A solar powered UAV seems at some level a no-brainer especially if it could fly high enough over the clouds & fast enough to always be in sun-light. The engineering behind it however is very complex. The project website has all the details you’d ever want!

The drive for renewable energy sources has been a heated issue lately. Here is a wind turbine project write-up that details out the process of using wind for generating electricity. The write-up is thorough and concise (but could use a few more pictures of the build process).

This project is a very basic battery charger using solar energy to do it! The best thing about it is that it uses standard house-hold parts and the design is easy to put together.
