I have just discovered your site, well done for the work accomplished since 2004.
at the moment i am interested in solar thermal energy and am glad to have found your forum.
so my wish is to find interested parties to manufacture together (DIY, or rather DIO "do it with other", I saw this expression on a site ) small prototypes, open source, which are based on solar thermal energy, in this case concentrated (CSP).
the idea is to validate (size) this kind of prototypes for domestic use, because it seems to me that financially speaking the CSP is more accessible (for modest households in France and in developing countries) than the photovoltaic, even if that I have seen that its price has dropped considerably compared to 10 years ago etc.
I am thinking of this kind of assembly:
but I saw that there are plenty of possible applications and assemblies, the one that produces electricity is the one that interests me the most (CSP / turbine / electricity) but cooking, distillation (water purification ), the cold, ... it's also very interesting (well for the same modest households, or not for that matter ..)
that said, I am not under any illusions, this kind of prototypes / installations, even dimensioned, etc., can only contribute to the consumption of a household (x%), therefore cannot cover the totality of the need, j 've seen that an average house in France consumes 3kW (you will correct me if you have other figures) and therefore if this kind of installation can provide 1kwh it is already huge in my opinion ... the stove in question continue to buy the other 2 kW, waiting for the day when the CSP (or hybrid) technology will allow more etc.
here, sorry for this long message, I hope that it interests a few readers, in which case we can talk about it more (moreover I am basically a physicist by training, computer scientist by trade and former handyman )
thank you again for your site and for this space of exchange
