All type of electrric vehicles should be encouraged even those that have a gas engine to coast along in case of failure of batteries.

All type of reserach should be funded thru state funds and people should be trained to use and maintain them on a very urgent basis.

member photo It is a shame that the only serious producer of electric vehicles in the USA is Tesla Motors; at $100,000+ per car, even the government cannot afford to buy a fleet of electric vehicles from Tesla. Government agencies are purchasing european Smart Cars and Chinese "Miles XS500" mini cars instead of cars from domestic manufacturers. It would be nice if the big 3 automakers re-opened some factories to produce electric vehicles instead of exporting out our manufacturing base to overseas competitors.

member photo The point is that US auto makers arestill very much focussed on the gasoline still!
There is little realization that it is only mini electric cars which seems to have future two years down the line.
Even in India they are all marketing and planning to build gas guzzlers!
Except perhaps TATA Motors!
They have built a nano car which has a consumption of 28 kms to one liter and also I believe Electric version is beig developed at a furious pace. The car to cost USD 3000 will have wireless internet as well and there are some great advances in engine design. Clearly it has international support.
TATA is toying with the another innovation that of assembly work. The kits will be shipped and assembled in specified workshops world wide under their supervision. This will knock out many problems.

member photo Mr. Norquay points out that Tesla is producing capable electric cars. What is missing however appears to be the typical evolutionary cycle of technological advancements. Cell Phones used to be $5000, weigh in at 3 pounds. Now they are available to the masses. Laptop computers used to be 35 pound suitcases, now they are a few pounds and the size of a common business folder. Tesla is the leader and producing new technology at the premium price, like all new technologies, usually only affordable to the very rich or NASA and the Military. As the technology matures the price will fall. Look at Big Screen LCD and Plasma TVs. The debate is whether the natural economic cycle can be survived due to the rapid escalation of fuel costs. That's an entirely different debate.

member photo Let me go ahead and declare myself vulnerable here... this is not my area of expertise and ashamedly so, I've done little research on the same... however, at least at a macro level if someone could please enlighten me, I would greatly appreciate it. It seems to me that a few drivers for electric cars are (not any particular order);

a) reduce dependance on OPEC and
b) reduce carbon footprint (this encompasses many other thoughts and drivers as well, emissions etc)

I would think that these batteries running the vehicles still have to be plugged into the grid eventually... if this is indeed the case, then don't abovelisted items a) and b) become unattainable? I'm sure at some point at least thats a risk. Has there been any studies done on the impact of say 5 or 10 percent of vehicles on the road being electric to the electric grid/consumption as well as what the reduction would or item a) listed above? Lastly, I would assume that the more advance the battery technology is the more attractive the option for electric vehicles become right?

Thanks in advance.

member photo Good questions Alex,

The good part about the new advanced battery plug-in hybrids and full electrics is they can charge at night when the grid has excess that fgets dumped and they vehicvles can use V2G Vehicle to grid connections to sell back during the peak when energy is needed most and the highest cost.

With new non toxic lithium battereis electrics can now go well over 200 mileas on a charge. They can go even in sub zero or very high heat. The batteries are being tested to last 100,000 miles and more. The altair nano lithium battereis were tested by aeroenviroment and said to last 500,000 miles even witrh rapid 10 minute full recgarges.

It's a whole new world for advanced battery vehicles. Imagine 1 million vehicles helping the grid. Imagine using almost no oil, imagine clean skys and water. It's an EVworld.com

member photo Alex, I did not see an answer to your question. Google states the Prius needs 117 watts per mile. Lightning Car Company in England gives information for their car that I calculated to be 200 watts per mile. An article I found today stated that as of 2006, Americans drove 3 trillion miles a year. At 300 watts per mile I came up with 900 terawatts per year, or just under 103 gigawatts per hour (assuming even around the clock recharging). That would mean a miniumum increase of 10.5% in extra generation. Assuming no change in our current generation mix, that would lead to an overall drop of 16% in US air pollution.

member photo Some additional benefits alluded to above but not clearly spelled out: 1) With a real-time electric market system, the (PH)EV chargers could be used to flatten the peaks out of present load curves, allowing high-efficiency baseload generation to replace much of the present low-efficiency simple-cycle peakers used for mid-day start-stop operation. 2) As in one, they could substitute for costly grid-level storage likely required in order to allow intermittent renewables like wind to capture any significant portion of grid demand. 3) With modern combined-cycle baseload turbine plant efficiency approaching 60%, even with the 5% loss in transmission and 15% lost in battery charging and power conversion onboad the car, a car can get more mileage from a gallon of gasoline if the gasoline is used to fuel a generating station and the resulting electricity used to charge battteries than to burn the gasoline directly in inefficient Otto cycle reciprocating engines. 4) Can potentially shift a lot of auto miles from gasoline imported from questionably reliable foreign states to locally generated (natural gas/wind/nuclear) electricity, see 3) above. 5) several others.

Given modern battery technology (eg. i do a fair bit of work in carpentry / metal work etc. and my only skill saw, recip. saw and drill are battery operated), the switch to battery vehicles esp. for comuters is a no-brainer and should be encouraged (or even mandated) ASAP.

member photo Advanced research based on Radioactive batteries can solve this problem.
I remember reading a Russian book way back in 1976 describing such a battery
Some one has to look up the archives to find this info
True the safety issues are going to be difficult but there are methods now to address it.

member photo There is growing lobby of Engineers who think that solar is actually basic which is what in reality it is !After all all energy do come out of solar- it was solar which produced the vegetation which became fossils in the end! The peaking of energy use in mid day tallies with the activity of the sun on most days.So if you connect the solar devices at the point where energy peaks it will flatten the normal demand curve because the production will cut the peak out of system.It is also the time one is in office and can charge his car.Is it not fitting in the scheme of things!Why wait till sun is down!
