Re: Thorium: the future of nuclear power?
This is only true for the version currently being tested by the Chinese; the versions studied by other countries (including France and Europe) practically all include a permanent purification system (of the order of 20 to 40 L per day) which evacuates the various fission products liable to .. .

Re: Thorium: the future of nuclear power?
At 36 'he confirms what I noted above: for the moment we do not yet know how to operate a molten salt reactor continuously. This is only true for the version currently being tested by the Chinese; the versions studied by other countries (including France and Europe) include practical ...

Re: Wind: for or against the wind?
Wind turbines capture subsidies very well, and that is where their real "utility" lies: they supply the economic circuit much better than the electricity grid ... They represent the archetype of the new economy by providing a pretext for the injection of liquidity. (overabundant ...

Re: Liquid nitrogen generator engine
in fact we must see the liquid N2 reservoir as a cold source, and the atmosphere as a hot source. there are dithermic thermal machines which can almost reach Carnot's yields (Stirling cycle for example). We could consider helium gas machines. A) A pr ...

Re: Liquid nitrogen generator engine
OKAY. But in what way is this "machine" not a dithermal machine, the hot source being the atmosphere (ie approximately 290 ° k) and the cold source liquid nitrogen (ie approximately 80 ° k); what difference do you make with a steam machine (hot source about 400 ° k and cold source about ...
