Mr. Godwin obviously hasn't figured out that for a Geo thermal well to
be shallow enough for a $9000 bore hole to reach the thermal area, the
house would have to have been built on top of a fault line. The carbon
saving therefore is made irrelevant when measured against the release of
the H2SO4 vapour clouds emitting from the bore...) doesn't seem like
enough of an incentive for me to stop burning coal in my fireplace in a
home located miles from the closest fault-line and move closer to the
reason for the H2S04.
Anyone that has been to Rotorua in New Zealand will know the smell I am
Who the hell wants to put up with that many rotten eggs for a little bit
of green warming ?
According to scientists in 1988, the earth was going to warm 10 degrees
I think it would be cheaper to buy some long johns $19.95 at Lowes and
await the Global Warming to heat your home - naturally.... much safer
than moving into a fault zone region.
(Buy two pairs on the dim, probably unlikely chance that they got it wrong.)
In other words if the scientists got it right then hot rock heating for
the home is a waste of money and Mr. Godwin is wrong.
And we know Mr. Godwin is wrong because we have political consensus on
