Resource Energy is developing a system that will store solar heat in the
Summer and Fall, to be used in the winter to heat your home or business.

While storing solar heat as a by product you will b able to cook your
food, heat water, and air condition your home or business..

The system will also produce enough DC electricity, to power other
appliances such a your TV, VCR, and computer..

You may still want to remain hooked up to the power grid, for
reliability...

The system will not only reduce the dependance on fossil fuel. it will
also reduce global warming, stored Solar heat will not warm the
atmosphere. stored heat will never come in contact with CO² in the
atmosphere››››

len=I am sure that will remain a company secret for the time being, or
the political left would shoot it down..

The left has no agenda to solving the problem of Global warming, the
philosophy has no real value except to bash Bush and the political
right.

A real alterturnative for the use of fossil fuel, would be a disaster
for the political left..

Precious. Why would politics enter into it? It's really quite simple to
show whether or not such a system would work using _science_. "The left"
couldn't shoot it down if the science was good. I'm having some trouble
imagining how a 100% efficient collection system pumping heat into a 100%
efficient storage system could provide enough energy to provide me space-
and water-heating through an entire winter AND provide enough excess to
cook my meals (yeah, the cooking all adds to the space-heating, but it
needs to be high-grade heat).

Quite. The answer is that it can't.

The very idea is barking mad but in today's climate I'm sure they can con some
investors out of their money which is most likely all it's about.

100 ton block of solid iron for thermal storage

Let's assume that could hold enough heat to get one through 6 months of
weather in which the average outside temperature was lower than you would
like your indoor temperature. Well, in winter, my outdoor temperatures go
down 50C below what I'm comfortable with, whereas ambient summer temps are
only up to 10C higher than I want. Even assuming that insulation will
solve much of that differential, I've got to have a mechanism to capture a
lot of extra heat.

My house has a lot of thermal storage (slab-on-grade construction, with hot
air passed through the slab). We left it unheated for 3 weeks last month,
getting only the passive solar gain, and while outdoor temps hit -30C, the
core of the house reached only +2C, and was +9C when we got home. So
that's our winter baseline and there's still 10-15C that we need to make up
to be comfortable.

Iron really isn't that thermally conductive. I imagine it
would work better as 100 tons of scrap iron pieces or 50mm
spheres with lots of air spaces and circulation.

Does it really matter if it's very conductive? Standard thermal storage is
concrete or water, either of which are surely less conductive than iron.
It's how much heat it can actually hold that matters.
Perhaps they are using some kind of chemical storage or
highly reactive desiccant system.

That would be my guess. I know of an experiment done here at Dalhousie
University, NS, where they attempted to use phase changes (solid-liquid) in
a salt to store large amounts of heat. Unfortunately, it was a little too
corrosive :)
