Over on the Make Blog Chris Connors posted about what he calls “meatricity,” human generated sources of electricity. The comments though are the enlightening bit. A number of readers discuss traditional conceptions of the “dirty” energy grid, the pros and cons of meatricity and more importantly the costs of implementation. Sure, human powered everything sounds sweet in a naive super future kind of way, but creating the devices to harvest the energy, may or may not negate the collection altogether. Until implementation is energy efficient though, it seems that tinkerers will continue to work away trying to find something that does work.
