[Public-list] electric repower, steam and diesel smell

Despite my nattering negativity, I firmly believe the future for small
auxiliary power is electric drive, but with solar power as the main power
source. If the technology dollars were pushed the right way, we could have
solar cells that could be painted on every deck surface and integrated into
the sails - and they would be 75-85% efficient. You would pick up a couple
of fuel cells on the way to the dock for extra power.
I think we could be there in 5 years, but likely not for 10.

As usual, great feedback. I didn't know about the clean water part and
haven't included an osmosis water maker in the steam propulsion budget.
Thank goodness the several thousand hours left (I hope) on the Iron Genny
affords me some time to watch the technology mature. Fuel Cells might have
some promise as well if we can figure out the hydrogen distribution and
storage thing (isn't that the stuff they put in the Hindenburg). At least
their byproduct is clean water (that I might be able to sell to folks with
steam generators). The lure of electric seems to be the peace; imaging
booking along at 5 knots (well, maybe 3 knots) on a calm day with no noise,
smell or vibration and actually being able to talk to someone below from the
cockpit. It also gives me time to look into nuclear, or as Carter and Bush
like say, "new queue leer." I like the idea of the whole boat glowing in
the dark, especially during night parades or in shipping lanes.
All the best,
