Hi Paul and all,
Actually you replied to my bull, I don't know how Bob's callsign got
dragged into it. (;->) Anyway, I was just doing my usual thing when he
comes out with the unexplainable. The whole thing is there is that
missing 25% energy he cannot or will not explain, it comes from the power
grid but he'll never admit that Albany isn't self sufficient and no city
is. That's what the power grid is for, a bit of "creative accounting"
when it comes to electricity, moving it around to where and when it's
needed like the proverb "no man is an island".
I'm just a bit sceptical when it comes to heat pumps, they work but what
about energy efficiency? They're just big air conditioners that provide
cooling in summer and on reverse cycle provide heat in winter, pumping
heat in either direction takes a large ammount of electricity any way you
look at it. For what it's worth, I've seen heat pumps installed in
housing developments only those use the Earth as a heat sink. It seems
logical when you go down deep enough since the crust is a natural
insulator, heat up a pocket in summer and draw it out in winter, a heat
resivoir. Still I wonder about efficiency and what the electric bills are
like, could be the reason why they're not so popular is they're cost
prohibitive.
Speaking of steam coming out of the outside boxes, I remember a huge
evaporative cooler on the roof of a supermarket when I was young. While
my parents were shopping I sat in the car watching this thing, much of
the time it was just water pouring over wooden slats on one side of a
huge metal box. Once in a while the fan would kick in and a cloud of
steam would pour out of it for a minute or so just like the heat pump you
mentioned.
