Ok,
If anyone can enlighten me...

You take an extremely efficient magnet wheel, that spins x amount of times from one push.

You connect that to coils to produce electricity.

How many watts could you get out of this?

How many watts does it take to power a house?

If you could just "sit and spin" the wheel (or wheels) once and a while, wouldn't that produce excess power? Not overunity, just sufficiently amplifying the human motion input.

Right?

actually electricity generators we use r just a wheel and some coils and we use the energy to rotate it.In that case u have no excess energy... household takes like 10-20kWh per day.

Hi,

It is ok you have a easily turning magnet wheel, turning for minutes from one push BUT the moment you approach this wheel with coils and use the induced electricity for feeding a load,  your wheel starts slowing down very soon and stops. Of course you may push it again and again...

Thank you for this little tidbit, I like getting numbers for this stuff.

Do you know if there are batteries capable of supplying 10-20kWh per day? Such as the deep cycle batteries used with solar power?

hey ,
for best numbers for your home case just check your electricity meter write down the numbers and after 7 days write it down again,then divide the difference by 7 and u get an approximation of what r u using per day.

about the batteries...probably guys from solar systems found already reliable batteries so google around (i have little idea about this).With car batteries u should be carefull not to drain them too much (never go with voltage lover than 10.5 V) so kind of circuit would have to take care of that.Typical car battery is capable of 65 Ah
so it takes 65 h to drain one with 1A current(so 12W load).Average of 10kW/h in 24 h gives like 450 W/h.One 12V car battery would run such a load for 37 min.
But of course u have peek hours (dinner cooking,dish washing) and those machines use as much as 2-8 kW.In off peek (at night) u use very little electricity. It is also better for battery to be discharged by steady low current,so battery bank would be the best solution.
