Power question.........?

The electric power usage for a household was 35 kW-h for a single day. Imagine that the power was supplied from batteries charged by a bicycle powered generator with 94 % efficiency. For how many hours must someone pedal the bicycle at a peak power of 560 W in order to fully charge the batteries?

To gain 35 kwh at 94% efficiency, then the amount of energy that must have been produced by the bicycle is:

35 / 0.94
= 3500/94
= 1750 / 47 kilowatt hours
= 1750000 / 47 watt hours
= 1750000 * 3600 / 47 joules
= 6300000000 / 47 joules

If pedalling at peak power gives 560W, then the number of seconds to produce this many joules is:

[6300000000 / 47] / 560

= 11250000/47 seconds

= 11250000 / (47 * 3600) hours

= 66.489 hours

= 66 hours 29 minutes 21.7 seconds
