Man Invents Alternative To Cooking Gas 553

An anonymous reader writes "Gazan resident Abed Ar-Rahman has revealed what he is claiming as an alternative to cooking gas that he developed since Israel has prevented deliveries of cooking gas to Gaza. He invented a device using chemical substances available in Gaza, which burn when mixed and brought into contact with oxygen. The first component is a metal filter that controls the interaction between 40% of the oxygen in the surrounding air, the inflammable substance and some other substances."

    What about Calcium Oxide (CaO), which yields quite a bit of heat when exposed to water?

    All you have to do to get CaO is burn limestone, which people have been doing since antiquity.

    From TFA:

    The first component is a metal filter that controls the interaction between 40% of the oxygen in the surrounding air, the inflammable substance and some other substances. He refused to reveal the exact substances used, fearing that they will not be allowed into the Gaza Strip.
    The second part of his invention is an electronic board that regulates the percentage of air and oxygen entering into the appliance, and the third component is an air pump using electrical power.
    The metal cannister could be refilled with the inflammable substance for no more than 40 NIS, which would make the home cooking device functional for up to 40 days, according to Farajallah.

    This would be neat if true -- a garbage disposal sized obvject providing 40 days of cooking gas for 40 NIS, but just reading alerts every single "perpetual motion" bullshit detector in my head -- the 40% figure, the secret ingredients, etc.

        From the article:

        He refused to reveal the exact substances used, fearing that they will not be allowed into the Gaza Strip.

        I'm not sure if he's full of it, or if his process uses substances just as objectionable to border security as cooking gas. Let's face it, Israel will figure out what the secret ingredients are, so I'm not sure what this is going solve. Maybe he's just trying to protect his invention until it's in production.

        • People do keep actual secrets secret as well; but anybody who has a mysterious fuel source of mystery, made by combining one common(but mysterious) substance with another and can't reveal it for fear of The Man, they tend to end up sharing a category in my mind with "the 100mpg water powered car that Exxon is covering up", "the universal herbal cancer cure that Big Pharma has killed for" and similar oh-so-very-plausible schemes.

            Yeah, if he's saying the other ingredients are benign but would be banned in an attempt to keep cooking oil out of Gaza, he probably subscribes to the water fuel and herbs newsletter.

      It might be as simple as an acetylene generator and optimized burners, where the transported "fuel" is actually calcium carbide and the cooker would mix it with local water to generate the actual cooking gas. I imagine it would be very difficult to make that work in practice, but some similar clever chemistry could allow an apparently benign (and unblockaded) material to be used for fuel.

      A 40-day supply does sound like a bit much, though.

            That's the point. Had I linked to any Israeli victim of terrorism, some dumbass would've come out from somewhere to debate, that it is all Israel's own fault, that they shouldn't have built the country in "somebody else's desert", or that they should've just died [umb.edu] in the face of opposition, etc. This way, there is no such distraction.

            Or, at least, it is much harder to make — blaming the deaths of Palestinian girls from a Palestinian-fired rocket on Zionist Entity is, of course, possible — had it not been for the occupation [umb.edu], there would've been no need for rockets, so there — but stretches credulity beyond most people's BS-meters. I'm sure, this explanation is being offered inside Gaza and, maybe, West Bank, but it would not work elsewhere. Or so one hopes...

    • by chrb ( 1083577 )

      The point is that using cooking gas requires a constant supply of cooking gas; smuggling in gas once is not enough, you have to constantly smuggle a large supply. Building this device requires smuggling in aluminium once. After that, they can burn whatever common non-blockaded chemicals it uses forever.

    Sounds like it might be a form of the Fischer-Tropsch [wikipedia.org] process, a catalyzed chemical reaction in which synthesis gas (syngas), a mixture of carbon monoxide and hydrogen, is converted into liquid hydrocarbons of various forms. You don't have to end up with liquid products. The catalysts are the things that would be the hardest to get in the Gaza area. You need electricity to run the process, but only intermediatly, to build up the product. The Germans made a lot of progress on this during WWII when their access to petro-products was cut off, yet the demand for POL was still high. The feedstock could be almost any organic material that can be volatilized, not necessiarily syngas, but the catalysts needed and the temperatures/pressures are a booger to work out.

    Or you could take a man or two, put them in a vacuum-sealed vessel, and boil off the hydrocarbons. Sort of like a "reverse gas chamber". If you don't want to be inhuman, use politicians - even PETA won't complain ...
