RE: Power requirements

[Robert Crawley]

As much as I want to test out some thermate, I think the water jets idea is
definitely going work. Needs a rotating head with a bit on the tip, so
either an electric motor, or have its spinning motion powered by the water
pump (which would last a lot longer), which sucks the water back in, heats
it up, and spits it back out. A gallon of antifreeze would probably go a
really long way. Is there such a thing as non-toxic anti-freeze? Heating the
water on Europa will need a radioactive power source, but we can probably
get away with batteries here. So you could probably get the thing to the
point that all you would have to do is switch out the power source (and
upgrade to rad hardened) and it would be ready to ship to Europa. The
biggest problem I can foresee is jets getting clogged. Which can probably
mostly be solved by coating the inside of the hoses with RainX and adding a
couple ounces of RedLine Water Wetter to the anti-freeze to break down the
water tension.

In response to my inquiry to Dr. Behar, he provided the following
information:

So we are *not* talking a small amount of energy to burn the holes
in the ice.  The 480KW would seem to be required over a period
of 12-24 hours (the time required to drill the ice holes).
