I just do not see the advantage of making synthetic fuel if you already
have fission energy. Why not use the heat to generate electricity
directly?
If you do need some liquid or gas fuel, just use hydrogen. It seems a lot
cheaper, if you have the fission power to spare in the first place.
The fuel resource is there, and the distribution systems for upgraded
kerogen or synthetic fuels are already in place.
South Africa has been producing synthetic fuels from coal and natural gas
for decades.
http://www.eia.doe.gov/emeu/cabs/safrica.html
"South Africa has a highly developed synthetic fuels industry supported by
abundant coal resources and offshore natural gas and condensate production
in Mossel Bay Sasol, with a capacity of 150,000 barrels per day (bbl/d),
and the Petroleum Oil and Gas Corporation of South Africa (PetroSA), with
a
capacity of 50,000 bbl/d, are the major producers of synthetic fuel in
South Africa "
The 240 volt 100 amp single phase service (25 KW Peak) for residential
use
would limit you to
1.0 pound of hydrogen (0.5 gallon gasoline equiv.) production per hour
with
a 2.5 volt 10,000 ampere state-of-the-art
electrolysis cell. Aside from the $5.00/gallon gasoline equivalent cost at
$.10 per KW-HR , how do you plan on storing it?
Upgrading residences to three phase service with power factor and demand
charges tacked on gets pricey.
A friend running a welding supply and metals business had to shell out
$12K
to get three phase
from a line a block away. The nearest 3 phase line from this neighborhood
is about a mile.
Synthetic liquid fuel would be useful if the electricity all comes from a
giant thermal farm in Arizona, in the middle of nowhere, but you can build
fission plants reasonably close to population centers, so why not use the
energy directly?
That is ludicrous.

This is not needed. There is no call to recharge a plug in hybrid
quickly. It can be done overnight.
Not at reduced cost if everybody is drawing off the grid at night.
If you forget, or if you do not have time to recharge, it does not
matter. It just means you use more liquid fuel that day, and pay more for
transportation.
Yes synthetic liquid fuel when the bottom of the oil barrel is dry
.
A method of rapid recharging during the day would be a big help for pure
electric vehicles, but it would make little or no difference for plug-in
hybrids.
I disagree. If you have 10 hybrids that want to charge 10 KW-Hr in 2
minutes, the recharging station
has to have electrical service for at least 300 KW demand capability.
Most likely running off a synthetic diesel fueled gen-set.
Do the demand math for 10 car 50 KW "Supercap" recharge in 10 seconds or
less. :-)
