Re: [Biofuel] Power harnessed one step at a time
How about harnessing footstep energy by actually walking to places? I am developing a distrust in attempts to squeeze the last bit of energy out of things. There are too many cases where extremes of specific efficiency are accompanied by gross whole-system inefficiency. That is, I have a growing suspicion that optimum efficiency is not always maximum efficiency.

They figure that the stomp of every footfall gives off enough power to light two 60-watt bulbs for one second. So I figure I take about 2 steps per second, and could light 2 60 watt bulbs for 2 seconds, (or 240 watts per second) every second.I've used a stereo that can make 240 watts of sound output, but I don't walk as loud as that stereo is... Where is all that sound coming from? Do people really walk that loud? doug swanson -- Contentment comes not from having more, but from wanting less. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * All generalizations are false.
