chemical heat production

[sam17]

Carbide is still found in some small neighborhood drugstores in france ...

It can also be found at the old camper (chain stores at the decathlon).

In the circles of the speleo it is very common. It costs quite expensive and it is not always easy to get, but actually it heats up when the water comes in reaction with. This, however, creates an inflammable gas which burns at very high temperatures with oxygen.

So much use lime then

Pitmix, my modules were purchased on ebay.

By making a plate full of modules, covered with glass, and with heat dissipator deriere, one could manufacture a generator of electrical energy.

Just Auguste!

IOTA, you make vibrate my (ne) neuron (s), lol tells me your idea, you think to be able to manufacture how much energy with this?

That said, it gives off a flammable gas which burns at very high temperatures with oxygen.

Hello

In French of the acetylene (practice for the blowpipe)

This is how you drink in Africa and mada, the bottles are too expensive.

But to handle with caution the limit between enough gas to heat and boom is very very fine

I hope to get some watts under 12v about.
It seems frankly feasible.
See post on effect seebeck-peltier in generator.
In my opinion it is more efficient than a photovoltaic panel.

But! the best is to use both

In addition, it allows to use other sources of heat as well as solar.

The Russians have used this technology from the 70 years for headlights.
A plutonium container heated peltier elements.
Around you can see fairly balanced wings.
These generators easily made more than 500kg because of the shielding (that's what I suppose ...)

This technology is also used in space probes and even pacemakers.

I wondered out of curiosity if it is possible to heat for example a camper or a caravan (in short a small volume) with the chemical reaction of quicklime and water.
Knowing that it is worth about 10 euro the 50kg.

that the reaction is: CaO + H2O -> Ca (OH) ² + 1155Kj / kg CaO.
