> If you have to pump enormous energy into harvesting the carbon so you can burn it and re-harvest it, why not just put that energy straight into the car and cut out the carbon entirely? Energy density. Jet fuel has about 25x the energy per kg as the best lithium batteries. Perhaps batteries will be able to match carbon fuels some day, but it's a long way off. |
