The tesla car has two motors that put out 760 hp, 713 lb-ft motor torque.

In the big version it has a battery that 90 kWh.

So to make the numbers easy let's say we have a motor system on a boat that has 100 hp. This would take 75 kW to power.

If the battery was 75 kWh, does that mean that it would run for 10 hours?

If the solar panels were 1000 watts then it would take give the boat 1.3 hp?

Can the boat be given a better motor that can hold 150 hp for many hours with less energy usage than this car that needs great acceleration and bump?

How will these number change as the TL increases? Seems that motors will not change much batteries might get lighter and smaller and the solar panels might be come much better. How good are they now? How small could they be now and get say 10,000 watts instead of 6 square meters putting out 1200 watts?

Thanks!
