This idiot keeps saying all you need to do is keep the batteries charged.

If you are discharging the batteries at a rate of 60kW, the batteries have to be charged by at least 60kW. Yes, I agree if you have a 60kW generator like this one http://www.generac.com/Industrial/products/diesel-generators/configured/60kw-diesel-generator and hook some batteries up to it, you can put out 60kW of electricity. According to this article: https://www.ablesales.com.au/blog/diesel-generator-fuel-consumption-chart-in-litres.html a 60kW generator will require 4.25 gallons of Diesel per hour. Diesel is generally $3/gal, so you're looking at $13/hr in Diesel.

That gives you 21 cents per kWh. That's well more expensive than grid electricity. Any electricity you're not inputting from a generator, you're inputting from the grid. There is no configuation of battery/generator/grid/converter/alternator/whatever that gets around this middle school fact. Seriously, you're talking to people with science degrees with absolutely no knowledge of what you're saying. If you're happy paying a diesel bill rather than an electric bill, good for you. But it's not cheaper, so just fucking stop.

the video is on a smaller scale for power output but the premise is the same
replace the the propeller with an electric motor and change the electric motor to generator drive ratio to achieve the desired rpm for peak output of the generator.. i cant believe you people cant understand how this works !!!
