"Fuelling the [Formula 1] cars will be a carbon neutral synthetic e-fuel, which may be produced from carbon dioxide captured from the atmosphere, harvested from food or agricultural waste, or generated by algae."
It would be interesting in knowing how this fuel is carbon neutral. It would seem no matter the source, the basic idea here is CO2 captured plus "process" yields liquid fuel. Clearly "process" must consume energy and so where does that energy come from? My understanding from a PBS program is that because CO2 is really not all that prevelant in the atmosphere you have to scrub a lot of air to get a little fuel. I don't know how much CO2 agricultural waste or algae produce but it does seem there must be some energy input to produce the liquid fuel. I'm not saying the process does not or cannot work, I'm just curious how it becomes carbon neutral.
If stuff plus energy E produces output energy E, I have gained nothing. And if stuff plus energy E produces output energy E prime > E, it sounds suspisously like perpetual motion. And if E prime < E, well I'm losing ground.
