If you look here, they are talking 5 minutes for 70% charge of the car, even though it is currently only a short range vehicle. Don't think a 300 mile range would be out of the question (within a few years) and would def work even in large countries like the U.S. Moving to dependence on our interstates and letting passenger rail services atrophy was a mistake, and now we will be forced to fall back on our rail networks more.Įlectric cars (that are able to fully charge in under 20 minutes) subsidized by a solar panel roof is the future. It's less logistics than politics, sadly. That was 40+ years ago that was put in so now it is harder to do put it in now. Slowly it is happening but really the system that was designed in the past was based around people driving their own personal cars around. It is very costly to retrofit those system in and it is a very slow process. Trying coming to some city west of the Mississippi and you will see how little rail they have and we just do not have any good way to put a rail system in. And again, electric cars are only as good as the powerplant they get power from, and that is where the biggest efficiency loss comes into play.Īs for the mass rail system. The energy efficiency of batteries is reasonably good, but they are still too big and heavy, as well as being expensive and dirty to manufacture. I read somewhere that the overall efficiency of an electric car is currently only about 5-7% greater than a gasoline-powered car (EDIT here () is a link for those numbers, but admittedly not a very good one). But the reason I'm skeptical is that we have no proof that a battery "breakthrough" is really on the horizon. I'd really like to agree with you, believe me. The plugin feature may actually make the car less green/efficient if you get the juice from a dirty or inefficient power plant. So all the extra tech essentially fails to improve on a diesel. Using only its onboard generator it gets about 50mpg (). At one point they claimed over 200mpg (), but that included a full batery charge from the grid. GM's own webiste is rather mealymouthed about fuel economy. The Volt is harder to measure because it's a plugin, so some power comes from the grid. Modern diesel hatchbacks like the Golf TDI (Euro engines, not the US-spec) can exceed 50-60mpg (). problem is they are a little on the heavy side but we are getting better at it. When we finally get a true break threw in battery technology I can see things really taking off.īatteries are very efficient at story power. The problem with battery right now is we are still working on a break threw. Now image if those very high gas mileage diesel running as a hybrid. You need to compare the generators (unlead to unlead). You are comparing diesel to unleaded even in hybrid form.
