From 2011. Their solution to compress air is poor, unless air powered tools is the energy user. Still pedal powered generators have not improved much. Rollers is best because of gearing, but it requires a bike. With a bike that is cheapest/simplest device, but requires room, and possibly moving bike indoors.
