You forgot to add the electricity bills for the life of your unit.


You lost sight of your electricity bill.

I think his point is you can get "free" energy from the environmernt
but, by the time you amortize your capital expense and maintain the
system it will be the most expensive way to heat/cool your home. That
is why I suggested using junk car parts or other "damn near free"
stuff  for your expiriments, to prove the concept and have some fun
without breaking the bank.
It will never be cost effective, the only question is how much do you
want to spend to prove that. Actually if you can make a somewhat
effective system for a few hundred bucks you might actually cool/heat
a small space for (almost) free.

Most western manufactured green energy stuff is too expensive, yes.
But if you check out some chinese manufacturers you'll get a pleasant
surprise.


That's my plan. Roof windows (with blinds for summer) are one
effective way but I need
something that works on winter nights and cloudy days here to heat
both water and house. I need about 3 kw of heat in total. Much of it
can come from solar.

No, Im not.
You have to look at the current and the future value of money.
Money that isnt spent today on large capital items like wind turbines
or solar cells can be invested which will produce dividends that will
pay your power bills forever more.
I looked at the option of wind power and useing a small example of
a 1KW wind turbine , installed cost UK 3000 pounds, that around $10K
AUD.

I chose instead to not go down that road aand invested $10K at 8%
which gives me a dividend of $800 PA which pays my entire power bill.
Not just the power bill for my small air conditioner.
A lot of people think that power or energy thats made from renewable
sources is somehow free as they dont have to pay power bills, but they
ignore the fact that the same capital invested will in most cases more
than cover all the bills you will incurr.

            A lot of people don't have $10K, but they may have
good credit and can buy energy saving equipment.

            Many if not most decisions are based on ability
to pay cash, or on available credit, and even with bad
credit it might be possible to buy an old gas guzzler car.
