MMmm so if I understand correctly the technology of the ram is a hydrostatic pump (well not really static but more static than the centrifugal one) ... I believe that I saw last year at the show of the inventor a system of pump that we met in a stream and which used the potential / kinetic energy of this stream to pump a small (depending on the pumping height) portion of the fluid passing through the pump body, I could find you the docs if you are interested really. In any case the main advantage is the simplicity of the system (therefore the low maintenance) but it is still necessary to have a nearby stream with rather good flow (therefore reserved for the mountains) to hope to pump kkchose useful ..


Thank you erzatz for the page:


Mass required to store the equivalent of one kg of oil (11,6 kWh - 1,3 liters roughly)

Wood: 2,22 kg

Lead acid batteries: more than 300 kg of batteries


Compressed hydrogen: from 15 to 30 kg of tank, occupying a little less than 30 liters

Mass in motion: 2 40-ton trucks launched at 116 km / h

Water at altitude: 43 tonnes of water capable of making a 100 m fall

Uranium: 1 milligram

Heat: 10 ° C rise in temperature for 1 tonne of water, or 50 ° C rise in 200 kg of water

We immediately see the enormity of the amount of water to store an altitude !!!! (I will check these calculations so it seems important to me) An inground pool seems the best solution to store heat (but hardly retransformable into energy) ...


I adore the conclusion:

1 kWh, so it's a lot when it comes to storing it, since it takes 30 kg of batteries for that, but very little when it comes to consuming it: on average, and all energy combined, a French person consumes around 45.000 kWh per year, or 5 kWh per hour! A man at work consuming a power of around 200 Watts, this means that a Frenchman has, through his energy consumption, the equivalent of 25 permanently slaves: these slaves of modern times are called car, boiler, washing machines, automated factories, etc. And these are not the "slaves" of Mr. Seillère or Mr. Messier, but many slaves of Mr. everyone

ps: an American was at 13 kWh per hour and a Chinese at 0.8 kWh in 2000. You see the problem that will fall on our heads?

okay !!
Very well
and is it really interesting or rather an advertising brochure?

Could you scan the most informative pages?

[Christophe]

Well, it's that ... when I talked about scanning the docs and simply the summary tables (if they exist) so we could put them in a folder on the site.

Otherwise it doesn't matter ...

Oriented PAC driven I do not believe in it too much and many people in the trades are of my opinion ... (see the file on hydrogen recently put online and the comparison of science and future)

By the way, what is the site where you made the request?

please

[Christophe]

I was talking about the address of the site not the email (which I had seen)

for authorization I think that if we quote the source + link it should go, it's not secret defense kan even?
you?
