32.7 million electric cars by 2015
I think this article only pertains to pure electric cars, though if we
include hybrid cars that have both batteries and an internal combustion engine, this figure sounds more realistic. Sill, 32 million vehicles is only a fraction of the total vehicles in the US. http://www.nanovip.com/node/54589 |

Haven't we heard the same types of projects for flying cars and cars that drive themselves over the last half century? It may be 100% accurate, but projecting such numbers 6 years to the future serves no purpose. Notation here - I'm not faulting lyon wonder. I'm faulting the source of the information.

Sill, 32 > million vehicles is only a fraction of the total vehicles in the US. > > http://www.nanovip.com/node/54589 What a hare-brained notion this one is. Consider the number of D, AA and AAA cells we throw away today, and multiply it by the additional demands of 32 million electric vehicles. Imagine the power needed to move just one vehicle, let alone 32 million of them. The number of AAA cells needed is mind boggling. No wonder there is an interest in electric vehicles, it is driven by greedy battery companies. Until the used battery problem can be solved, electric cars will be a major danger to the environment. Why aren't the auto manufacturers compelled by law to use rechargeable battery technology? Is it because there is a major conspiracy between government and the Asian battery manufacturers lobby? -- |

Unlike any other battery technology, thin film solid-state batteries show very high cycle life. Using very thin cathodes batteries have been cycled in excess of 45,000 cycles with very limited loss in capacity. After 45,000 cycles, 95% of the original capacity remained, according to the report." so here's my question - what happens if/when this breakthrough occurs - whether it's next year or 10 years from now... What happens? What are the things besides this breakthrough that would cause a shift to electric cars away from IC-engine cars? |

32.7 million electric cars by 2015
Don't dare forget that some of the first vehicles offered for sale to the
public in the earliest days of automobility - well over 100 years ago - were battery-electrics. And the reasons why they failed in the market in the 1890s and 1900s will be the *EXACT SAME* reasons why they will fail in the market again (see: charge range, turnaround time when refueling, etc). That oft-recited quote - "Those who fail to learn from history are doomed to repeat it" - applies here in full force. -- ___________________________________________ ____ _______________ Regards, | |\ ____ | | | | |\ Michael G.

I think the point is that (barring huge techno-leaps) if electric cars come to market with the same old issues of range, fueling time etc, they'll fail again, regardless of the battery technology. Joe Sixpack cares not a bit about the battery...he just wants a car he can drive across the state and refuel on the way... > > you know.... you can power an electric engine is a wide variety of > ways separately or in combination with fuels and batteries.... hybrids > have been around for a long time - remember diesel electric > locomotives? > > and now.. the Navy is building warships with electric engines.. > instead of shaft engines....

Using very thin cathodes batteries have been cycled in excess of 45,000 cycles with very limited loss in capacity. After 45,000 cycles, 95% of the original capacity remained, according to the report." so here's my question - what happens if/when this breakthrough occurs - whether it's next year or 10 years from now... What happens? What are the things besides this breakthrough that would cause a shift to electric cars away from IC-engine cars? Some fantastic mpg numbers are being mentioned for the Chevy Volt, http://gas2.org/2008/04/05/150-mpg-c...ak-peak-video/ and http://www.usatoday.com/money/autos/...-07-volt_x.htm, among others, mention 150 mpg. While I do not want to discourage anyone from buying an electric vehicle, I think that a reasoned look at the energy cost of driving electric vehicles is warranted. The Chevy Volt is said to have a battery pack of 16 kilowatt-hr and a full electric range of 40 miles, http://www.chevy-volt.net/chevrolet-volt-specs.htm. That calculates to average electricity from the battery consumption of 0.4 kWh per mile. How much will it cost to drive an electric car? Using the Volt's 0.4 kWh per mile, and an average electricity cost to residential customers of 11.35 cents per kWh; (http://www.eia.doe.gov/cneaf/electri...able5_6_b.html ) I calculate a PRE-HIGHWAY TAX cost of 4.54 cents per mile. And the 4.54 cents per mile assumes that there is no energy loss in charging the battery, and no energy loss in the conversion back to electricity; in my opinion this is a very optimistic assumption. Would the4.54 cents per mile cost be a significant savings? In my humble opinion the savings is OK, but not anything like the above 150 mpg would suggest. The Chevy Volts appears is classified as a compact car. Several compact cars (Ford Focus, Honda Civic, Toyota Corolla) average more than 25 miles per gallon. In recent months gasoline has been selling below $2 per gallon. Of this $2, $0.50 is highway tax, so in effect; the PRE-HIGHWAY TAX cost of gasoline is below $1.50 per gallon, or around 6.0 cents per mile for a 25 mpg car. (At highway-tax-paid cost of $2/gallon, the per mile cost is 8 cents per mile.) This is clearly more than the 4.54 cents per mile calculated above, but nowhere near the savings the 150 mpg would suggest. By this calculation, driving a car with 33 mpg is likely to have the same PRE-HIGHWAY TAX energy cost per mile as the Chevy Volt running on electricity. In my opinion, if there will be millions of electric cars on the roads, governments (state and Fed.) will have no choice but to put a highway tax on electric cars. Furthermore, if the number of electric cars will increase to the millions, the demand for and cost of gasoline is likely to drop, while the electricity demand and cost rise. The cost of electricity is likely to swing less drastically then the cost of crude oil and gasoline. Electricity supplies and cost are less likely to be effected by OPEC and others. But, electricity and oil have a fair degree of interchangeability (homes can be heated with oil, natural gas or electricity); I think that energy costs will tend to even out in the long term. In the above calculation, the electric car may give an energy cost saving of about 3.46 cents per mile. I tend to drive my cars around 80,000 miles before trading. During those 80,000 mile, I would buy 3,200 gallons, and at $2 per gallon pay $6,400 for gasoline. Driving an electric car for 80,000 miles, would cost $3,632 (80,000*0.0454), a savings of $2,768. When electric cars will have to pay highway tax, the savings will diminish. If gasoline prices go to $4 per gallon, and electricity cost would remain the same, and no highway taxes on electric cars, then the saving would increase to $9,168. I will seriously consider buying an electric car, when the price premium for that electric car will be no more than $2,768! Since I can buy a car with 25 mpg, but I do not think that any battery will work at 100% energy efficiency, I consider the $2,768 premium a upper limit. Compact cars like the Ford Focus cost less than $20,000. Numbers like $35-40,000 are being mentioned for the Chevy Volt, http://gm-volt.com/. Tax credit of $7,500 will help, but in my opinion GM needs to bring the price of the Volt below $25,000. More than 50% of electricity in the US is generated from coal. In my opinion, electricity, as is generated today, is more harmful to the environment and causes more global warming than gasoline. The above is not intended to discourage people from buying electric cars, but I would like to start a reasoned and reasonable discussion on the cost of driving electric cars. Ernie |
