We could take the gasoline, burn it to generate electricity and use that to charge electric vehicles. If you consider the massive efficiency advantage, we'd probably still come ahead over using internal combustion engines.
This is in other words a complete non-issue. But I'd love to hear plans on safeguarding inevitable hydrogen leaks in residential areas. Should we tell people to get rid of their garages?
- sliverstorm 12y agoI think you are confused. Gasoline drive is perhaps 30% efficient. Electric drive is perhaps 80%. Charging batteries I don't remember, but let's call it 80%. So what you've proposed is: Burn gasoline (30%) * Charge batteries (80%) * Drive e-car (80%) = 19% efficient It works better if you have a very high efficiency gasoline-powered generator (a 60% efficient generator gets you 38% efficient) but that can't really be done at the homeowner scale.
- revelation 12y agoI guess you are underestimating just how terrible internal combustion engines are and overestimating charging + driving losses. Consider that hybrids or HEVs can improve substantially on the efficiency of just a pure ICE. I guess the problem with using an ICE for driving directly is that you are often forced to run it at RPMs and states where it is nowhere near that hypothetical 30% efficiency, simply to get the acceleration the user demands.
