Gravity Battery
Monday, April 17th, 2006Batteries are an essential part of almost every portable electronic device. Unfortunately, battery technology has not kept pace with other areas of technological innovation. While devices are often tweaked to be more and more efficient with their power consumption, little emphasis seems to be placed on actually creating an innovative and more effective portable power source.
Now what’s interesting to me is that there are a number of power sources readily available to any given portable device. The challenge is to find ways of usefully harnessing this energy. Obviously such a task is not simple to do, but consider how much energy is generated by simple external forces such as gravity, sunlight, wind, motion, air pressure, etc. Surely it is possible to convert these forces into electricity.
My vote is to use the force of gravity as the power source for a micro-generator which could keep a traditional chemical battery charged enough so that I would never have to plug-in my laptop again!
