I can't see how batteries will ever be a more efficient or convinient way to distribute energy for use in transportation.

- ysleepy 4y agoRemember that combustion engines are only 25% efficient in extracting the energy from gasoline.
- cdot2 4y agoAnd gasoline has such a high energy density that even at 25% efficiency it's more effective at storing and transporting energy than batteries.
- SigmundA 4y agoYou can burn unrefined oil at a power pant at 40%+ efficiency saving the losses in the refining step and with all the complicated emission controls not in the vehicle.

- LatteLazy 4y agoBatteries are not a distribution method, no one plans to distribute batteries. We will use the same transmission systems we do now for that...
- SigmundA 4y agoPower plants can burn crude oil directly without refining at a higher efficiency than a gasoline engine with much more sophisticated emission controls. Power is then transmitted by the grid at about 5% loss vs transporting with tanker trucks which is around 2% loss. The refining step itself has losses on the order of 15%. You can burn domestic natural gas at 60% efficiency in the power plant as well, mix that with that with renewables and it's easy to see how you're ahead. Look up well to wheel efficiency for more. Batteries can be recycled creating a circular economy there once enough are in circulation.
- Schroedingersat 4y agoIn 70% or so of the world, just park the car under a carpark sized solar panel with a 20kWh buffer battery and have a little induction pad under it for one full charge per week. Hook up to grid for more if you so please. Seems a lot more convenient to me.
