"Unburning" CO2 takes energy. Where does your energy come from?
- rmcginnis 7y agoWe use zero carbon solar and wind electricity. As long as the electricity source is zero carbon and low cost, it makes economic and practical sense to make zero carbon fuel.
- PaulAJ 7y agoSo what is the efficiency of your process? How many joules of chemical energy do you get from 1 kilowatt hour? (i.e. 3.6MJ)
- fallingfrog 7y agoOk but why not just use the zero carbon electricity, if you have so much of it?
- zamfi 7y agoThey're going after the use case of gasoline as energy storage, not gasoline as primary energy production. The reason, today, that cars are powered by gasoline and not electricity is not the cost of the energy itself, but the cost of storing it. Obviously it would be better to use the electricity directly. But it's hard to get that electricity to a moving car on the road (or a plane in the sky).
- fallingfrog 7y agoIt’s not that hard. You can just charge the car inductively with wires in the road, or better yet, just lay tracks for electric trains.
- zamfi 7y ago> It’s not that hard. You can just charge the car inductively with wires in the road I’m sorry, are you proposing this solution as being cheaper than either gasoline or batteries?
- ramraj07 7y agoThere's a difference between a regular car and a hotweels toy
- eMSF 7y agoYour "not that hard" solutions don't solve the problem you answered to. You can't move a single (production) car out there with wires in the road, or by laying tracks. Perhaps it's a bit harder then, after all?
