    1 lire/ day. That’s going to take a lot of scaling up.

    Yeah, I saw that. That's a lot of energy and real estate for a miniscule return. Still, the idea of making jet fuel from water and carbon dioxide is mindboggling to me.

    And we better hurry up. Because today evidently is the day of George Jetson's birth.

    Yeah, a bit of work to make this viable.

    Didn’t we have cars running on water back in the 70’s?
    I see millions of federal tax dollars going to support this. The end result will be to provide the principal investigators and a few other hangers on with a nice living. But no viable product.

    It's simply reversing the combustion reaction. That's going to require as much energy as was released when the fuel was burned (which is a LOT), plus whatever inefficiency is in the system, which also seems to be a lot. The question is whether the efficiency can be improved enough to require less energy input than biofuels. Soybeans are pretty efficient at converting water and C02 into oil, but it also takes a decent amount of energy to produce them.

    I would think plants or algae would be a much easier solution. I recall something about a pilot/demonstration algae to bio-diesel used "gray" water from a sewer plant. The algae was sensitive to chemicals so the water had to be slightly processed before siphoned off. But seemed like a much better path forward to me.

    Too lazy to read the whole story. But why couldn't they use nuclear power instead of solar? Way more efficient in terms of not using as much of the limited space on the planet for power collection.

    It's literally reverse combustion. In normal combustion, carbon chains and oxygen are burned to produce CO₂ and water (H₂O). In theory any reaction can be reversed.
    A great example for this is an LED light, which is a diode that emits light. Some diodes are made in a way where they absorb light and emit electricity - those are known as solar panels.

    I saw the announcement on GAMI's G100UL approval yesterday, Paul. George Braly has been fighting for approval for years and his perseverance finally paid off. :cheers:

    +1 on that process requiring an obscene amount of energy
