way around. Diesel-electric propulsion will also use the prop's traction
motors as generators to recharge the batteries with every available hp
under sail....

Now you're talking! A genset and a modded Solomon, with these nanotube
babies instead of 14 house batteries and another ton of lead and acid
to haul around.

Larry, do you know if all that microscopic surface area equals a high
mass and/or density? Not that it's likely to be an issue: if these
lithium/nanotube batteries have the same weight and dimensions as
lead-acid, the ability to rapidly charge alone would find them a ready
market.

If you think Rolls and Surette are expensive, just think what 1,000 AH of
lithium-ion batteries is going to cost! :-)

This is the problem, and why they won't be used as traction
batteries in mass market vehicles for awhile.

There's been a lot of talk in battery circles lately about "the lithium
economy."

Ahhhhh, but what a Battery you would have, comapred to what is available
now......

They are TINY by comparison. That little Li-Ion cell in the picture with
the big spade lugs coming out the bottom is something like 5AH! The name
of all this game is SURFACE AREA. The tiny tubes have a larger surface
area than any known thing on the planet! Microscopic channels where
electrons can be stored, directly, like in the ultracapacitor or chemically
in Lithium ions....all in parallel for amazing capacity.

Keep a close eye on this evolving technology. At the moment, it answers a
LOT of tough questions about electron storage we never had answers for,
before.

Tiny and light....a cellphone you charge once a month in 3 minutes flat.

Next time that damned VHF marine handi goes dead 500 yards from the
dockhand you're trying to talk to, wish those cheap-assed NiCds NMEA put in
it were these new Li-Ion cells....(c;
