ant that is the idea to get out much more power than put in. I have seen 50 kW generator being very easy to spin by hand. and if the generator is producing the maximum power at 750 rpm, a 2 kw motor with 2800 rpm and a gear box to increase the power and to reduce the rpm to 750 will it still...
hello to everyone, first of all I apologies for my bad english
the idea is - i will use 2 KW motor to spin a 50 KW alternator or generator.
the cost to buy electricity is 17 p/kWh and to sell it to the grid is 5.1 p/kWh
so my motor will use 48 kW in 24h with a cost of 8.16 pounds in 24 hours...
