Bonjour Sycomoreen : les WPV ? un abuleux champs d'études imaginé par un ingénieur de géni

Hi Serge,

Thanks for your post, you should give a link to precise your works.

Bye !

I'm working now Carnot engine. At low Delta T, it is twice better than a Stirling engine with 75% regenrator efficiency. In fact a Carnot engine
has no dead volumes and no regenerator. The temprerature shift between isothermal processes is obtained by adiabatic processes.
At the end it is possible to reach easily CNA efficiency at full power.
An the mechanical design is simpler than a Stirling. When Delta T increase The engine size become unfeasible. But under 300°C this is the best thermodynamic engine we can built. Nothing is better !

Bonjour ! : Superbes vidéos sur Cathy et Opale : il me semble avoir reconnu la route qui mêne à vos installations photovoltaïques....BRAVO ! magnifiques expériences électriques dans cette magnifique région qu'est la vôtre !

Hi Pascal, Indeed, we have worked a lot in 2010... And the gifts are there... Thanks !

I think everyone must keep to go ahead for 2011

what is it ?

great score of your site on may 2010

Hi Pascal, thanks for your question...

The financial pay back-time is about ten years. The Carbon return on investment is about 4 years.

The duration of life of the panels is 25 years granted at 80%/90% of the initial electric efficiency (unless a climatic disaster like very hard hail occurs).

We're working on OPALE to shut down the thermal stresses, especially during summer and to raise up the production.

Bye !

HI Raymond,
your photovoltaïque installation is a big one : nice !
just a question :
how many years for the payback ?
with the selling of your electricity to EDF ...
"it's very good to imagine...better to do it"
in yout country you imagine and you do it : great ! great !
Have a great day
