In the realm of exciting energy-saving news, a company named Humdinger has released a small wind-energy device that is ten times more efficient than its gigantic turbine counterparts. They call it the microBelt and it works by capturing the vibrations of a tiny string moved by the wind. The startup company has come up with a concept using a single string that generates a minuscule 2mW , but I can see where adding to the design could effectively produce enough energy to replace a car battery.
Humdinger is still trying to get funding for mass production and is trying to work with partners to make the design fit with specific devices. Expect to see the concept out in the wild some time soon!
