Battery powered Fast Launch 26

[Pericles]

For an Electric Thames Cruiser Mkll, use Thoosa motors bolted directly to saildrives fitted with Autoprops. Select size required.

Enhanced batteries.

For the British weather, an FL26 will need a canopy. Scroll down.

I'm working on ideas for a canal / riverboat version too. My idea is to stick with diesel and buy used frying oil from local restaurants. Colza is now at the same price as diesel I wonder why...

My instructions are "build a house first" so I'll be watching your progress. And we need a canopy too but not to protect us from the same elements

One of my ideas looks much like the boats you have linked to. In the plans it is written "do not make the cabin too high and too heavy". For a boat used in unprotected waters I agree but my thoughts are now use only in very sheltered waters. I think that the boat will get more use if moored close to home.

Just thought I'd up the ante with this information about battery power.

http://en.wikipedia.org/wiki/Supercapacitor

http://en.wikipedia.org/wiki/ZENN_Motor_Company

I do not think we are looking at a scam here. What we could be seeing is one company developing a product that will render a number of technologies null and void and put paid to some lines of research. Lithium phosphate batteries are barely getting started and now we have Barium Titanite.

The next few months look very exciting.

Spoke with an inventor that says he has attained a contract with EEStor and has the capacitors in his posession. They store some serious power, and recharge quickly.

Im also impressed with Altair-Nano's batteries that hold a similar amount of juice as the EEStor caps, with a 30 min recharge cycle.

Interesting stuff, but still a ways out for John Q. Public.

There will be no Altairnano when EeStor get really started. It's about price. Altairnano are hoping to get their price down from $2 to $1 per watt hour.

EeStor published this.

# For a 52 kWh unit, an initial production price of $3,200, falling to $2,100 with mass production is projected.[6] This is half the price per stored watt-hour as lead-acid batteries, and potentially cheap enough to use to store grid power at off-peak times for on-peak use.

# No degradation from charge/discharge cycles, because they are not batteries.

Half the price of lead acid. Bye bye lead acid!

Oddly enough P, EEStor already has a product, and has done an initial production run, while Altair has only a proof of concept battery and some intent dollars from their Chinese supplier of parts.

Id love to see this develop soon. 52Kw is enough to run a car for my wife's daily commute.

I've been following the Estor claims. A Canadian electric car co. called Zenn, I think, has a contract and claims to intend using the Eestor supercapacitors in 2009. Lockheed also has a contract with them for military use. Still, I have seen no claims that anyone has seen a working eestor supercapacitor. Some say it's more scam than not, but it seems promising. Where'd you here about actual capacitors being produced Eric?

I talked with a fellah who wants to use them on a boat repowering scheme to replace diesel engines in trawlers with small charging motors and solar arrays. He says he actually physically has one in his posession, and I believe him after talking for a week or two. He was interested in having me build a hull for him (HMD18 was what I was going to propose), but when he learned that I was under 30 he lost interest rather quickly. Something, im guessing, about lacking capital investment expenditure.

Ah well.

8 hours at displacement speed. They don't say how long at planing speed.

If shes 2000lbs, and the battery packs are 15Kwh, and I am estimating that the top speed is about 35, you can do the math backwards pretty easily. Unfortunately I have 2 guests here so far, and 25 more set to arrive today, so I can't spend the time.

Also, looks like NiMH or Li-ion packs, big voltage (144) and short charge times.
