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.

Solor powered wifi is the best of all worlds. The biggest challenge for people in developing countries is power. Electricity is hard to come by and most of the time simply not available at any cost.

ClimateLab has deleloped what they call a “solar node” that uses solar PV panels to create the energy needed to charge batteries, that in turn run a wireless router so that many people are able to get online at once.

Basically the idea is that a tower is constructed, and a large circle of the ground is covered with a material that sits 3-15 feet off the ground. Light can shine through the material, heating the air underneath the material and funneling it toward the only escape for the hot air, a tower at the center of the circle.

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.
