womens nike free black Can Electric Vehicles Take Off A Roadmap to Find th

COMMENTS
A few thoughts:1) for now, given the range limitations of electric, PEV’s remain our preferred choice. A PEV will be our next car purchase we can’t wait. Ideally, we’ll charge it on a home solar system. Ultimately our dream is an EV charged by a home solar system womens nike free black.2) What of Better Place? I can’t help but think that their battery replacement system holds hope for solving a number of critical logistical problems people have with EVs. For example: a) range limitations: most driving is fine on one battery. But want to take a road trip? How about purchasing or RENTING an extra battery or two and perhaps a charging unit..? This would seem to be possible with a Better Place type system…b) charge time: the possibility of pulling in and getting a fresh battery in a minute or two is certainly more convenient than having to charge for hours.c) end of life: once batteries wear thin, this type of system would seem to be ripe for a cradle-to-cradle approach to battery life, where the deliverer of new batteries to stations can also pick up ones that have reached the end of their usefulness. I know that also happens today, but it would seem to be particularly easy with Better Place systems.Could somebody please comment on whether any of the major automakers are working on partnerships with Better Place all black nike free, and if not, why? (While I’m a scientist nike free hyper trainer, I’m no EV expert – I’ve just read about these systems and they’ve seemed to make the most sense out of any of the EV approaches)Thanks!

This sounds almost exactly like what the Electrification Coalition proposed over a year ago. Is there any content here incremental to that?

In the article, you say “when compared on an energy-equivalent basis, electricity prices are 60 to 80 percent lower than gasoline prices”. Actually, prices are fairly close on an energy-equivalency basis. A $4 gallon of gas contains about 33 kWh of energy nike free run blue black, or $4 worth at 12 cents per kWh, close to the US average.The lower fuel cost of electric cars is due to the fact that electric engines are far more efficient than a gas engine, and require 60-80% fewer kWh to power the car an equivalent distance.

I can comment on the Better Place model. I’ve been driving a production EV for over 8 years now (Toyota RAV4 EV circa 2002). I recently purchased a LEAF and have about 2 months behinds its wheel.I rode in a Better Place converted Nissan SUV in Tokyo last June while it drove into the battery swap facility and 60 seconds later drove back out with a full battery nike free run trainer. Very slick. Here’s why it won’t work, at least not for general use.The battery packs in the modern EVs are integrated into the structure of the such that they can withstand tremendous impacts, and therefore a quick release, while not impossible to engineer, is at least very expensive. There is no standardization of the battery chemistries or the size of the packs, so each of the battery swap stations will have to stock numerous copies of potentially dozens of packs, keep them charged and wait for a particular car to come use one. The batteries are rather expensive, so the capitalization costs of building the station and buying lots of packs combined with the operational costs of staffing and supplying the electricity are substantial. With that in hand, what is the income stream? Well, most BEVs will have a capacity of anywhere from 20 kWh to maybe 30 kWh. The average cost of a kWh in the U.S. is 10 cents nike free 3.0 red. The station will have to buy those from a utility, then mark them up for their profit. You’ll make maybe a dollar or two if lucky.This doesn’t come close to penciling out.And when you see that the competition to battery swapping is fast charging on 50 kW, and even 120 kW DC chargers, taking 15-30 minutes to fill the battery, you begin to see that the swap idea isn’t viable by a long stretch. You also have the plug-in hybrid as a competitor for long distance trips. Or, the BEV driver who only goes on long trips now and then could just borrow a friend’s Prius or rent a car nike free trainer fit.Shai Agassi has raised a lot of money on this concept, but when you think it all the way through, it’s not really viable nike free 5.0 canada. I’d prefer he stick with getting a good BEV on the road asap. We need as many as we can get, and we need them fast!

At long last people are beginning to see the alternatives. The only issue I can see is the retention and charge up times of the batteries. So to combat the issue, why not designate battery sites alongside pump stations blue nike free, and literally change the battery?

I keep waiting for an obvious use/test of many new alternative vehicles, the Postal Service.Their fleet has stop and go driving demands and is visible to all. What a terrific opportunity.

And is coal the power behind these vehicles?If so, not clean.Also all this focus on driving is just a cultural con from the auto industry.

I think many of the problems we face are due to private car use – no matter what fuel/energy system they use. Cars are the problem – they take up huge amounts of resources and far too much space. They also kill and maim people at an astonishing rate which we seem to have come to accept as the price of progress. Electric cars are only marginally better since they produce no emissions as they are used – but they do produce all kinds of issues starting with the extraction of rare earth metals all the way through to how they are disposed of at the end of their life. And in use they cause just as much traffic congestion and require just as much parking space. Their drivers are no safer than IC car drivers. Worse there is the Jevons paradox that encourages people to use them more because they think that somehow driving an EV or hybrid exempts them from all controls. Indeed, many states encourage this view by allowing them into HOV lanes, or giving them favourable parking places.EVs are are a dangerous distraction from the real needs of this planet – which is to get people to use more of their own motive power (walking and cycling) and – where that is impractical – public transport of all kinds. Moreover EVs are really essential to the promoters of nuclear power generation as they provide an essential place to dump excess power in off peak periods (nuclear power stations being really hard to turn off!)

Firstly I fully support demonstrations of new transport technology. That is the best way to let people see options nike free black and white. The present global reliance on oil based cars is very mature from a marketing/economic point of view and subject to considerable change with emerging concerns about oil and carbon emissions. If a demonstration is promoted by an R&D group or local govt etc why not look at a wider range of alternatives. Why not improve the second transport corridor(currently called bike paths) and allow as well as bikes, low speed powered micro vehicles including Segways nike free women black, faster mobility chairs, mini golf carts etc., hopefully at low cost, (covered from rain ?) maybe with licencing for safety mgt, to get people from home to transport nodes, shops, work etc, say for up to 8kms (5 miles) as a way of maintaining mobility and flexibility, but maybe for one family member (relating to a % of the current fleet) substituting a say 50 kg machine for a 1500 kg car, with significantly lower cost in manufacture, running nike free hyper tr womens, and possibly road building. This could cause a different approach to urban planning so no one would consider without proven demonstrations.I own a car and ride a bike to work nike free plus 2, but most people don’t or wont.What bothers me about the current developments in electric cars is that they are trying to replicate oil based cars. The Volt is around 1,400 kilograms with high performance nike free 5.0 v2 mens. While cost will reduce with scale there is still a lot of energy to make and operate one for moving a person around. The main pluses seems to be efficient running in urban areas, use of off-peak power supply and avoiding reliance on imported oil. A modern small diesel car seems to use less energy than an electric one on a long trip.

Does this mean that the price of the electricity will go up? And in the future will not be able to pay electricity for our homes caused by the raise of demand wholesale nike free shipping??This doesn´t seem to be the way, it´s more of the same. Will be completely dependent of the electricity companies like now we are from the oil companies.

Electric vehicles have no exhaust pipe, so are often touted as pollution-free.They are anything but. The first generation of electric vehicles will be fuelled by power from our national grids and most of that is from fossil fuels.That still makes them marginally less polluting than a gasoline engine vehicle, but marginal is the operative word. Electric cars that can virtually match the performance of gasoline cars are a non-solution, though they may be a ‘feel good’ purchase.The public sentiment that to buy one will give us a free green ticket to heaven is badly misplace nike free run red grey. Small electric cars will have a place in the energy mix of the future nike free 3.0 ladies, but we should get away from any romantic sense that they are inherently green.

There seems to be little understanding here of EOREI (energy output relative to energy investment), and that 3 times more energy is used to make/maintain/dismantle a car than it uses on the road in it’s lifecyle. And of course this takes for granted that roads will be there men s nike free 3.0, and in A+ condition into the future.I still occasionally use a car, and whenever possible I ride an electric-assist cargo bicycle. It is ecologically light years ahead of any car, regardless of what fuel the car runs on. It allows me to do a lot of my round town work as a Permaculture gardener/designer. I also run a stall at the local market via the bike and a trailer.Cars require roads and a settlement pattern that is not sustainable. The cultural imperative of cars and roads really needs to be looked at nike free black sole. In the face of the 6th Mass Extinction event, it is severe hubris and highly anthropocentric to think that modern industrial “civilised” humans must have a continuance of car culture.On ya bike! Go local so you work at or close to home and don’t need a car.

“As a nation, we do not need to use more taxpayer dollars to persuade technological enthusiasts and green consumers that they should buy an electric car nike free 3.0 canada.”No, but to give EV’s a chance on an uneven playing field caused by fossil fuel prices that don’t reflect the harm the do and to help the R&D of this new technology.In my opinion we should put a tax on fossil fuels, but since that is far from possible in the U.S…

Gasoline & Diesel vehicles carry only half their fuel: the other half is atmospheric oxygen nike free trainer men. The electric vehicles need half-a-ton of batteries, and still have limited range.I’d say they should expand beyond golf carts into local delivery vehicles with a defined route. USPS would be one good example. For long range vehicles, I’m not feelin’ it for the future of EV’s. They’d need to develop batteries that could compete with today’s gasoline tank: a pourable liquid that fully utilizes chemical bonds throughout the whole liquid, wasting none of it on structure, with the other half of the fuel taken in through the air cleaner. How can you compete with that?Better to use the electricity to fabricate synthetic fossil fuels.
