Yes, my real name is easy to find.


I have prepared my site for this purpose (http://wims.unice.fr/xiao/
solar/index.html). But I am afraid that if things develop, someone
else should take in charge of this site, or build a better one
somewhere else.

Yes. My collectors will be manufactured there. I count on the success
of this one; once it is the case, whatever drawing I send there,
people will rush to manufacture.

Thats awesome Azuredu, you have a privileged situation to make it
happen, even in a commercial perspective.

In regards to the project being developed and someone else take
advantage and credits for that, youre absolutely right, unfortunately.
Its a tough decision to keep things by its own or to form a group of
enthusiasts for cooperation, because sometimes we get stucked on
something that someone else could help, especially in homemade/DIY
projects. In my case, I think Ive done the right thing on sharing
some ideas, because I easily found many ideas and issues that I didnt
figured out until that.

Well, anyway, I hope I can contribute with something and Im
interested in both a partnership or to simple discuss alternatives to
find out the most viable model of solar concentrating devices. At
least here in Brazil, there is a huge market to explore, especially in
the countryside (rural areas). Grid energy here is not that cheap
(energy transmission losses + taxes), we are exposed to potential
shortages in the medium to long-term (in spite of the escalating
cogeneration market of sugarcane mills), etc.

There is no relevant company in the local market, even for standard pv
panels (still very expensive to buy locally and tends to increase due
to the recent Brazilian Real forex devaluation...).

If you want to do business with the new technology, write me in
private. There are great opportunities for people who understand it
faster than others.

How about using solar energy to heat a tank of water.  The water
expands and drives a piston which lifts a load.  A ratchet saves the
stored energy of the lifted load.  At night the tank cools down and
the system resets itself for the next day.

Just to play a bit around: who can find errors in the following

Water is incompressible. Which means that the thermal expansion of
water has a force that can be arbitrarily high. Even if the distance
is relatively small, the energy contained in the expansion is
arbitrarily high, and we are on the road to get a perpetual motion.
