I wonder what the price is...

Money, or rather lack of :(

I reckon that I could build everything but the generator.

On a more serious note, I wonder when Stirling generators will be more commonly
available, and at an
affordable price. By that I mean available to the home market.

I have been looking at CLF arrays driving a steam engine / generator. On
investigation, the steam
side of things seems to have lots of pitfalls.

I am currently waiting for details of the White Cliffs installation in Australia

I even looked at Thermopiles

but to get any usable power, it costs a lot!!!

The mechanical Stirling will probably always be price-comparable to a
two-cylinder two-cycle internal combustion engine. That's what sparked
my interest in fluidynes - which are "plumbed" stirling cycle engines,
rather than "machined". If you can build a trough and do some basic
plumbing, then take a look at
http//www.iedu.com/DeSoto/Projects/Stirling/Fluidyne.html for ideas.


Agreed, but I think it's possible to produce power a lot less
expensively than most folks think.

The major problem with this type of power generator is the curved
mirrors.
These are expensive and hard to make unless you have access to a glass
grinding machine.
Its far better to use flat mirrors even if the efficiency is less.
