Not very interesting. What a waste of CASH in these difficult times, and more advertising for the 'make me rich by going green' brigade. Solar
does have some uses, so does wind
power, but not economically where mains power is normally available.
The batteries are a little more interesting but expensive and no 'duty life' data available.
Three days seems over the top when diesel/gas/petrol would be a better back up system.
It takes solid cloud cover to stop any power from solar
cells during daylight hours.
As a workable cruise
vessel it would have spacious accommodation under that array but few sea view cabins. As a load carrier, what is it's useful tare weight?
Something with this plan area would be better as a surface skimming (ground effect) aircraft, especially if solar power would maintain flight in sunlight! even if it needed a boost to get airbourne.
assisted heavy carriers are in use, and saving ten percent over standard vessels. We'd save even more fuel
if we halved the speed of shipping
, but the shippings cost goes up so not yet. As boats slow down then sail or windmills become more useful. Time and crude oil
prices will inevitably drive these things eventually.
Some of the American naval stealth cats at least give better performance for lower operating costs. In My Humble Opinion.
