General availability: I want to buy an EV - they are just not available across the US yet (the Volt is a Hybrid, not an EV).
Where do you get the "E"? I agree that clean and safe generation is an issue. Lowering our consumption of energy would also be advantageous. I just installed a solar voltaic array on my house for the eventual support of an EV. So while I await actual availability of vehicles, I will just be lowering the amount of electricity I get from our local significantly-hydro-generated power grid.
As long as you insist on carrying around your own oxidizer, you'll always lose on energy density. I favor a standard format aluminum-air primary battery or a fuel cell, which in either case uses "free" reagent for half of the reaction.
A prismatic Al-air battery set could take seconds to swap (not hours to charge), you could carry a spare to ease "charge jitters", nobody has to handle high voltage high current charging at the consumer end. The battery station is also a zero-consumer-effort head end for recycling the material in a closed loop. Standard tractor-
trailer delivery just like gasoline.
A tank-fed fuel cell would have a relatively high comfort factor, pumping is pumping more or less, and ought to be on an energy density par with (or better than) fuel alcohol / E85, which our government sees fit to subsidize so it must be great and suitably performing stuff. Methanol could be totally infrastructure compatible at the
consumer outlet end. Fuel cells compatible with longer chain hydrocarbons, I haven't heard much about but a feedstock-agnostic reformer that yielded free hydrogen and carbon powder, would fix your greenhouse problem right up.
You guys have got EVs all wrong.
The Volt and Tesla are "statement" vehicles - like an H3 or corvette. Not what the future of EVs will eventually be.
The real EV market is for a sub $10000 car, with rubber floor mats and two seats. A dock for your cell phone, speedometer, and charge gauge, that's it. No heater, just heated seats. Ultra basic, ultra reliable, no maintanence except for the battery. Underpowered. New battery every 3 years.
Your second car, you drive to work. Or your kids drive it to school. Or your kids drive it at college.
Will the current car companies make this? No way. They want to sell $40k cars. A car like this will come from a company that has no market share at all - like Volkswagen did with the bug. Compare the bug to the cars of the 50s. It is ridiculous how cramped and underpowered it was, but people loved them as a second car. Cause they were cheap and reliable (in their own way).
So picture a car that you get a Costco or Walmart - that is about as complex as a washing machine.
25%/year is far, far higher than Tesla Roadster drivers have experienced. Automotive-grade Li batteries, in the highly pampered environment that the cars enforce, are seeing annual degradation rates of about 25% cumulatively over six years of regular use.
A gas-fired car will always have a bad emissions profile. An EVs' indirect emissions will get better as the power sector gets better. With EVs, therefore, you automatically amplify the benefits of adding clean generation. Moreover, even on today's first-world grids, EVs result in far fewer emissions--you can add advanced pollution control devices to power plants, but not to 300 million cars.
Multiphasic energy scavenging is the only viable solution to reducing fossil fuel consumption. The problem was described by another poster...."where does the 'E' come from"? Unless it's hydroelectric, most likely it's either from burning fossil fuels or far worse - nuclear fission. Harvesting energy and converting it to E and ME from all conceivable aspects, i.e light, kinetic, wind (the turbulent eddies behind the vehicle), vibration, heat, etc. is necessary. One might have to drive a little slower or lighten the load at night though...
That depends a lot on where one lives. Many in Southern Cal have SCE as their utility. SCE currently has 44% zero carbon sources and 37% from natural gas. The zero carbon is increasing rapidly. Some is listed as "unknown" so it is not assured that the rest is all coal, but I'll assume worst case it is. With that mix, an electric car would have FAR lower carbon footprint than ICE.
EV's make a lot of sense here where we have carbon friendly power and a density/geography problem that causes smog. We are also a big market for hybrids/EV's because of those reasons and that the state gives stickers that allow people to use the carpool lanes as single drivers.
Exactly - today the subcompacts cost as much as the big cars (and their mpg isn't all that great either). How cheaply could a single model car be built that complied with USA regulations (safety, pollution)? An Indian Nano made in the US for the US market perhaps. The French 2CV was a great hit in France for years.
