Re: [cdn-nucl-l] " Gas-main rupture "
I understand the sentiment but I don't worry about the gas
line into my house any more than I do worry about the other managed risks
at my home. I suspect there are more electrical related deaths than
gas related deaths. No one was hurt in the Montreal incident.
So I assume we can manage the risks of any of these technologies.
If the overall cost gets too high because of the safety features, then it
won't be used. At any rate, the big driving factor for using gas,
oil, etc for heating is efficiency. My high efficiency gas furnace
is 97% efficient I think. Why not, given that heat transfer can be
100% efficient in principle. But if you use a heat source to do
work (ie pump electrons up hill) the heat engine efficiency is typically
30 to 40%. Using electricity is quite an inefficient way to heat a
house. It does make sense to use electricity to run a heat pump,
though, if the pipes can be economically installed in your back

When we finally get to liquid fuelled reactors I wonder if we can have
reactor in every house and pump the fuel to them through the old gas
pipes. Boy, we sure do invent crazy systems! Gas should be
centrally and the energy moved to our houses as electricity. The
of a gas pipe running into my house is terrifying.
