You must be joking thinking you can run a miner from pedal power surely

As for gas I don't know but I'm sure if it were possible it would've been done by now.
Better off sticking to whats known and that's cheap or free electricity and efficient miners.
It's not just pedal power. Look up DIY 1000watt wind turbine.
Also it's not just purely from that. It's switching back and forth from home electric to alternator when the battery bank runs dry.
Have 5000 watt battery bank and you get 15 hours of free power from an S3 after charging.
Or it's running the alternator on your grid so it doesn't power the miner directly, but takes cash off of your monthly bill...
