[PSUBS-MAILIST] Commercial question

[Alan James via Personal_Submersibles]

Thanks Phil,
you've blown the 1 hp per ton bench mark out of the water.
I'm looking at Lithium for my upcoming sub & was Googling what they are using in the electric car market.
The Nissan Leaf has passed the 100,000 sales mark World wide. They must have a pretty reliable battery & bms.

Surely the price will be coming down. It costs 19,392 British pounds to replace it's 24kw battery pack.
Incidentally the batteries are made in Tennesse.

Re: HP per ton – We are now running the big ‘Newt-screws’ (unofficial name) 
on both the dual and single DeepWorkers. The single two thousand footer comes in 
at just over two tons and has 20 HP (4 X 5HP combined vertical and horizontal) 
These units can be dialled back to any rating up to a max of 5 HP  -if you 
want to conserve batteries and don’t need the extra oomph – we’ve also switched 
to LiOH battery packs. 3 times the duration at half the weight – what’s not to 
like??

Which may explain why that big anvil in back kicks such serious ass, even 
with Captain George's dinky prop.

That puts K-350 at the heavy power end, a strong  2HP per ton if you include the maneuvering motors.

>Better a question for Phil, I think. Gamma has  2 hp and weighs 2 tons. PC-12 had a combined 13 hp for 8 tons (10 main plus  two horizontal and one vertical maneuvering thruster). The Pisces boats used  a pair of 5 hp thrusters for 12-12 tons. So it is beginning to look like  about 1 to 1.5 per ton, now that I think about it.
