Originally posted by Tony Belding How often do you drive more than 200 miles in a day? For many people the sheer convenience of charging at home and starting every morning with a "full tank", and never having to go to the gas station again, far outweighs the inconvenience of long road trips. Then, when you do eventually take that long trip, having to stop for 20 or 25 minutes at a fast-charging station probably won't kill your soul. (Especially if the station is next door to Collin Street Bakery, like the one in Waco!)
Only if I drive from home to work. And it is not 200miles for most cars but more like 40-50. For many people just forgetting to plug the car one day mean they'll be stuck at the end of the next day to commute. It also mean that when I go to ski on the weekend (200km return trip) I am stuck. Fast charging station? There are none, in particular, not near the ski station. Go back see my father by car? 500kms on highway so how many time will I have to wait 20-25mins, counting that most stations don't even have support? It will add 2 hours to the trip and would be very boring. At that point I'll take the plane and theses guys don't work with electricity.
Fast charge reduce drastically the efficiancy of charge (so more electricity is needed) and destroy the batterie life meaning you polute more and have to replace them as used more often.
Originally posted by Tony Belding Who is renting batteries? Where did that even come from? Electricity is far less expensive than gasoline -- even at today's gas prices, never mind whenever the next oil shock hits. Plus, there's very little routine maintenance required: no oil, belts, filters, spark plugs, and typically much less wear on the brakes due to the regenerative braking.
The batteries are very expensive and need to be changed often. The idea also to not make people wait for charge at the refill station and to avoid drastically reduced efficiancy of fast charge, you directly exchange your empty batteries with one full. Were I live I can't buy an electric car and own the batteries. I can only rent them, the monthly cost for the rent is arround the price of 30-50 gallons of gazoline a month.
This also avoid to say have to spend 10K$ or more after 5 years for new batteries, maybe only 1-2 years for new batteries if you abused the "fast charge". The guys would have the impression you ask them to buy a new car each time.

I think it's widely understood by now that we need to clean up the electrical grid, and that's happening and will continue to happen. Thus, the electric car only gets cleaner. Of new power generation that came online last year, the majority was solar. Meanwhile, coal is dying rapidly.
Most of it is made with fossil energy or nuclear energy. And gasoline can be made from crops. They are so called "bio" even if I find it a joke to use crop for gazoline while we could give the food to people, but anyway. You just don't need to replace anyway. If all transport was using electricity, you have to more than double electricity production worldwide. And until we have way to solve the issue that renewable don't produce all the time, but at best like 1/4 of the time, that mean multiply capacity by 10. Maybe in 200 years, and only if you sacrifice huge area of the earth to that, replacing forests etc with this.
Originally posted by Tony Belding 2. Energy production and distribution is far, far more energy efficient than the production of gasoline. To start with, gasoline refineries are some of the biggest users of electricity in the country, and the electrical power used to refine your gallon of gasoline could propel the electric car roughly the same distance. Gasoline engines top out around 30% efficiency, as compared with 90+ for electric motors.
Are you sure? Look at that:
http://www.eia.gov/totalenergy/data/annual/pdf/sec17.pdf
Geothermal: 16%
Hydroelectric: 90% (don't forget you have to destroy big area to cover them with water to use that)
Solar photovoltaic: 12%
Solar thermal power: 21%
Wind: 26%
And a batterie discharge: (
Car Battery Efficiencies
Li/Ion: 80-90% efficiancy
Pb/Acid: 50-92% efficiancy
NiMh:66% efficiancy
For electricity transport from power plan to home:
How big are Power line losses? - Schneider Electric Blog
"The
overall losses between the power plant and consumers is then in the range
between 8 and 15%."
Don't forget also that the better the autonomy, the more batteries you have, the heavier the car, the more energy it need to move. You can store many time more energy (like 20-50 time) in 1 liter of gazoline than with 1kg of batteries.
Quote: 3. Lithium-ion batteries are not highly polluting. Lithium is non-toxic, and it's perfectly OK to put the batteries into household garbage and landfills -- not that you'd want to, since the material contents are worth recycling.
My father actually worked in env that required instant electricity backup in case of failure. The only viable solution was Pb/Acid. Theses suckers tend to emit hydrogen in some case. This is so conveniant to store, that you need a dedicated building for that (so if it explode, it doesn't burn the hospital with it), it is forbidden to be alone there and there constant monitoring. Yeah sound fun. This is considered high risk.
And also read a bit here:
Tesla's new batteries may be harder on the environment than you think | Vital Signs | The Guardian
Even the guys that produce the batteries are cautious with it. The batteries even lithum-ion are highly poluting, still require fossil energy to be made theses days and are not able to store the quantity of energy we need.
If we had all cars replaced with that, we would likely have to mine for a few hundred years to find all the raw material... That's not for tommorow.
Originally posted by Tony Belding I agree that people will not pay more for a vastly inferior product. They will, however, pay more for a vastly superior product, which is why Tesla have been selling the Model S as fast as they can produce it. That's also why there were, at least count, 400,000 people waiting in line to buy the Model 3. That's no small cadre of eco-weenies.
Yeah compared to hundred millions of sales of fossil fuels car, less than 1% and only for insanely rich people that stil have other cars anyway.
