I think electric vehicles make more sense in highly populated cities, where there are air pollution and noise concerns, and where it's easy to have charging stations everywhere. Maybe in suburban areas families could have an electric motor scooter for running routine errands in town. Once again, it's an example of people in cities trying to push a solution that's not so practical for everyone else.
The grid is much more efficient than shipping more fuel. An electric motor is more dependable than an ICE. You can do most of your charging at home and only buy fuel for long trips.
I don't know about that... About 10% of the power is lost is resistance losses in the power lines and step down transformers. A regular sized fuel truck typically carries around 6000 gallons. If we quickly assume fuel economy of 20 miles per gallon and 200 mile distance, that's less than a 2% loss. I realize it's much more complicated than that but that's just a quick calculation to give you some idea. For longer distances the fuel trucks are much bigger with larger capacities. For a fuel tanker, the ship is carrying so much fuel the percent losses are insignificant compared to all the other distribution on land, I would guess.
Those batteries are the most expensive part of the car. Yes, theoretically a system could be set up where, you'd just swap out your batteries at a fuel station for a replacement and it would take less than 5 or 10 minutes. But there would be all sorts of complicating issues with this. For one thing, the stations having all those extra battery packs sitting around would be expensive. The cars would probably require a complete redesign to make switching out the batteries faster and more convenient. Some sort of automated machine could probably do it but that would cost a lot of money too. And in the case of a disaster where huge numbers of people were trying to flee, the station would probably not have enough battery packs for everyone. Now in the case of electric city busses there are some interesting designs where the bus uses a capacitor that can instantly charge at some of the bus stops, but these capacitors only have a small fraction of the energy storage capacity of a battery, so would need to recharge after every 5 stops.
The idea has been mooted before and in a situation like the one the OP was building you might be better off with a "swap and go" than keeping your existing battery. Bit like the gas cylinder system here - you can either buy a cylinder and refill each time you need it or just "swap and go" with a fully charged one
The cost to recharge an EV at home is about $.04/mile. You'll have to haul a lot of gas. A series hybrid can run as an EV for most people most of the time. They would only need fuel for hurricane evacuations and vacations. The cost for an EV is up front in the batteries. Brakes even wear less because of regenerative braking.
Lol I think you found the exception that proves the rule. Did you see a lot of those cars driving around in the 1970's? There really weren't many improvements in electric car technology until the late 1990's and then more dramatically in the 2000's. That's one ugly car. I thought the Nissan Leaf was ugly but that's blegggh. https://en.m.wikipedia.org/wiki/Electric_car An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable batteries. The first practical electric cars were produced in the 1880s.[1][2] Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engines, electric starters in particular, and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicles. Since 2008, a renaissance in electric vehicle manufacturing has occurred due to advances in batteries...
I didn't find it I was alive back then, it's just the whole point of battery electric cars ( I am more big into fuel cells providing the electricity) I still don't see battery's being the source for the future. .
Get a solar flare (like the one that knocked out the eastern coast in the 1980s ) or a EMP and the electric grid is done, why we haven't addressed that already is anyone's guess.
Now add in the maintenan Those graphemes superconductor capacitors are the future. They charge fast, hold a lot of energy, are environmentally neutral when disposing of them. One day I would like to see the battery from my volt continue to be used in my home to store electricity generated from solar but that kind of energy independence is not encouraged where I live as of right now.
Ha Ha, they've been holding out on their customers. At least it's a better surprise than the Volkswagen diesel emissions scandal.
Having batteries fully discharge is not good for them so a percentage is always held back to avoid full discharge.
the tesla car is not really tesla, as in nikola. we had the technology for 120 years to power electric cars wirelessly but the banks gubmint and powerful interests burned his work down. more
Step down transformers are 95-98% efficient. Heavy vehicles like fuel trucks get around 5 to 6 mpg so your loss is up to 1000 gallons over 200 miles which is a 16-17% overhead ona 6k load.
Sure thing. Conspiracy theory. Basically the distance an electric car can go has not changed in 120 years.
famous last words from those who dont know the difference. lol best thing to do is actually research the matter before posting programmed uneducated responses.
Depends on the coupling coefficient. Meyls version creates an artificial or virtual ground which is necessary for operation of a mobile device. This paper explores the potential of using coupled electric fields between two tuned resonant transformers as a means for transmitting considerable power (>500W) over laboratory-scale distances (5 to 20m) with reasonable efficiency. http://ieeexplore.ieee.org/abstract/document/5307364/?part=1 With tesla, unlike others, especially the diaper brigade seen on some forums, if he said it works you can take it to the bank that it works. more:
Wireless is definitely capable of charging an electric car at 240 volts. http://www.greencarreports.com/news...-wireless-charging-for-nissan-leaf-chevy-volt
Not being IDK, combative or anything, but it sure looks theoretical from a practice standpoint. We really should have started working on it in earnest a century ago!
