Hmmmm, OK firstly I am not bagging this idea. It has merits. But there are a lot of figures that just don't add up and a lot of figures needed for comparison, that are ommited.
OK so firstly, lets presume we have no losses in the system. She is 100% efficient just for this excersise. So we have a 12Hp motor which = 9KW. At 144Volts, the motor will be drawing 62.5A. That means for the 6x 24V solar panels
, they will have to provide approx 250W each. That is mighty big panel. Ofcourse there are losses, lots of it with Solar
. So looking at a generator, to run this, well there are losses there as well. Everytime you convert some for of energy to another form of energy, you have a loss. So the Genset losses energy and the motor losses energy and the wiring
and the speed controlling and so on. A diesel engine fitted direct to a propellor is actually more efficient, a gearbox
slightly less. But the part about propellors and torgue at low speeds and so on, is actually full of a few errors. Plus, it is interesting that all the boats listed are what I would consider as being on the very low end of horspower to wieght/length ratio for Diesel, let alone the Electric
The hydrogen fuel cell
has potential. But it is still too expensive and I don't know what ongoing costs will be if any.
Anyway, just my thoughts.
