Bike generators are powered by people. People biking require time. What is the labor or opportunity cost of having all of these people sustaining 250W per hour or essentially a .25kW-hour? Just a thought but that doesn't sound cheap.
- sesqu 14y agoThat's exactly what jsilence is saying. Energy from the grid is so incredibly cheap that you're using it without a second thought on things you would never consider doing without a grid. It could go up hundredfold before becoming expensive. Also, kWh/hour is just a kilowatt.

- kleiba 14y agoIronic that you should link to that page, given that your grandparent post contains the phrase "250W per hour or essentially a .25kW-hour".
