No, it’s entirely feasible, it’s just that it probably requires about 5 times as much energy input as it produces. What sounds ridiculous is the claim of 70% efficiency. The “water gas” reaction (with carbon monoxide and steam) has of course been known for many many decades and Fischer Tropsch since the 20’s.
It takes a lot of energy to take either water or carbon dioxide apart and F-T requires something like 60+ atmospheres of pressure.
If the reaction heat from a nuclear reactor could be used to boil the water and produce the energy inputs for the F-T part, more and more of this becomes feasible.
The process is not BS. What is BS is that they are going to get solar or wind power to provide enough energy to make the the conversion. A better way to do it is to use coal rather than water and CO2.
In fact this process was used by the Germans to make synthetic fuel in WW2. They used coal to provide the electricity to convert coal into synthetic fuel. By mid 1944 nearly 50% of all the fuels used by the German military were made this way.
It is VERY energy consumptive however and you don’t get nearly as much energy out as you put in.
Rather than the silly solar or wind power something like a pebble bed reactor would be a better way to get the power required to do the conversion.
“*why does it smell like BS?*”
Probably because alchemy would be required for this to happen.
has all the feel of a LENR realse
*why does it smell like BS?*
I don't know, carbonated water always made me burp, not fart.
Because water (H2O) and carbon dioxide (CO2) cannot be fuel sources because they are
ALREADY “BURNED” (combined with oxygen).
