300 watts?
My daughter's stereo uses more power than that.



Only when you're on the phone.....(sigh)

Not so!

Russians have been running remote navaids with RTGs for decades.
Amazing power source used in lots of space programs, as you can see.

The half life of this generator is 87 years, so you only have to buy ONE to
run as many boats as you'll own in your lifetime, passing the RTG on to
your kids to run their boats from.

"238Pu (the best of these three) needs less than 2.5 mm, and in many cases
no shielding is needed in a 238Pu RTG, as the casing itself is adequate.

238Pu has become the most widely used fuel for RTGs, in the form of
plutonium(IV) oxide (PuO2). 238Pu has a half-life of 87.7 years, reasonable
energy density and exceptionally low gamma and neutron radiation levels."

Voyager 1 has been running from its RTG, nearly faultlessly, since the
1960's! It's power output has dropped, markedly, requiring a lot of its
science to be shut down or cycled, now.

Your permanent 110 watt SRG is ready....sun not necessary, 24/7/365/87
power...

owning a car that never needs fueling....which would, of course, starve
many of the elite class out of their mansions.

As with anything associated with the "hydrogen economy", spend some time
researching how these substances are produced.

I believe most hydrogen is made from natural gas or by electrolysis.
Be easier to make methanol, from natural gas, and use that for liquid
motor fuel. My car runs on methanol. Lot lighter than compressed
hydrogen or natural gas, once you include the weight of the tanks.

Apparently hydrogen being the lightest
molecule will leak right through most metal tanks.


Hmm...great point, Bruce! I suppose it's the same as the lighest elements
of gasoline leaking right through those cheapassed polyethelene gas tanks
they put in expensive boats...leaving the shellac behind.

Bruce was almost right. Hydrogen is the smallest molecule and it
leaks through normal joints like a sieve. Helium being the next
smallest is commonly used for leak testing high vacuum equipment as a
result. With the proper detection apparatus you could leak test with
hydrogen but it has an unfortunate tendency to release energy in a
rather violent kind of way.
