[PSUBS-MAILIST] Aluminum Batteries

[Brent Hartwig <brenthartwig@hotmail.com>]

Wil,
 
Today was the first time I had heard of aluminum batteries, so I have allot of reading to do.

> The basic problem is that if you want to do something with your sub 
> that goes beyond tech talk and subber events you need RANGE.
> 
> What means you need either a mothership, a tow boat, or a long range 
> cruising capability.
> 
> I also experienced the behavior of not following the tow boat when 
> pulled with a line in a small boat of 1 ton i built earlier this could 
> roughly compare with a K-boat.
> 
> The solution coupling sub and tow boat parallel and with fenders helps 
> to make it moveable (some) with a outboard motor. In severe wave 
> conditions this is highly problematic.
> 
> Even the 20ton sub with its streamlined shape was hard to tow for this 
> (not follow properly on a line) reason - so i experimented a bit on 
> this problem.
> 
> This is the outcome:
> Your boat will follow the tug if you put a big vertical plate on its 
> heck that works like a fin.
> The more aft the fin is the more efficient. You also can attach a long 
> plasic tube firmly to the heck (five meters at least) to create a 
> similar effect. This will make the nose of your boat follow the force 
> from the rope.
> 
> I recently thought about aluminium batteries as a way to get high 
> energy density for long range cruising in a small boat.
> Keeping in mind how little energy a submerged streamlined boat needs 
> to move (see economic submarine cruising on my website 
> (concretesubmarine.com) this could give a K sized boat (streamline 
> optimized) a couple of miles of range without the need of a combustion 
> engine, a mothership or a tug.

> Anybody a opinion on Aluminium batteries ?

> Surface transit or towing is far from ideal with "our" type of subs.
> Except for Kraka then.
> The Nemo team told me that towing Nemo is not working well , even with a

> The sub tend not to follow the tow boat and At higher speeds they dive.
