Why was the electric car made?




Diana


or factors that occurred to encourage the creation of the electric car.


Answer
"1834: Thomas Davenport invents the battery electric car. Or possibly Robert Anderson of Scotland (between 1832 and 1839). Using nonchargeable batteries." http://electricandhybridcars.com/index.php/pages/electriccartimeline.html At the time the only alternative was a steam car also in early development, rail transportation and the horse and carriage. Petrol and diesel powered vehicles were not invented until later.

By 1900 there were more steam and electric cars on the roads than petrol vehicles. Electric cars were favored in cities by their ease of operation and as an alternative to another pollution problem. In NYC alone more than 10,000 dead horses had to be removed from the city streets each year. But by 1910 the petrol vehicle had become an electric "hybrid" with the new electric starter and became the dominate vehicle.

Small numbers of electric vehicles have been built over the next 80 years, the largest fleet may have been English milk delivery trucks: http://www.milkfloats.org.uk/

By around 1989 GM had won a Solar electric car race in Australia and designers were challenged in house to build an electric car. The result was the prototype called "Impact." It was on display in California. After one display to the California Air Resources Board (1) The GM official quipped "I hope you are not going to make us manufacture this vehicle." That is exactly what CARB did. Seeing that a Zero Emissions Vehicle was technically not only possible but already prototyped they wrote the law requiring a small percentage of each manufacturers vehicles should be ZEV. It became known as the ZEV mandate. Car manufacturers complied and sued CARB as a board and individually. The tactic worked and at a hearing 2003 where they essentially ignored cries to keep the ZEV mandate they modified it and the manufacturers promptly collected and crushed their vehicles.2

GM sold the rights to the NM HI battery to Chevron who refused to allow its use in a "pure" electric vehicle. But they were used in all the hybrids and proved very durable in the RAV4ev. A great deal of misinformation about EV was published. The "Oil" president of the US called for "hydrogen cars." (Hydrogen is mostly made from fossil fuels.)

Then came 2008 and gas prices went through the roof. Suddenly peak oil and global warming seemed like very good reasons to put electric vehicles on the road. Every manufacturer had in the development or prototype an electric car. The 2006 Tesla roadster eliminated the question any question if electric cars could be made fast. Corporations are less motivated by adverse publicity and so cautiously begin to embrace electrics for their delivery fleets due to the savings in operating costs. Electric cars were not "killed" and did not die but their widespread introduction and expansion into the marketplace was delayed by 10 more years.

Which countries now have full-electric car technology besides China and Japan?

Q. BYD e6 electric full-size SUV: http://en.wikipedia.org/wiki/BYD_e6

Nissan LEAF compact electric car: http://en.wikipedia.org/wiki/Nissan_Leaf

* Chevrolet Volt is not full-electric besides it needs gasoline as fuel.


Answer
It depends upon what you mean by "full-electric car technology" and by asking "which countries"...

Electric cars are not a national phenomena. They are things. National policies can promote electric cars but to my knowledge no country has nationalized an electric car building company and is producing electric cars on their own. Corporations may give some a feeling of national pride or identity but many corporations are multi national and may hold allegiance to no country.

Countries and areas that promote electric cars with incentives are more likely to attract corporations that are making electric cars. Such companies are in some ways not very different than other corporations. If an area will provide certain grants, property, utilities, or tax incentives then companies are more likely to build a plant in that location. Having cheap labor and reasonable lines of supply are also a plus. Selling their products may require a different set of incentives to attract buyers.

A case in point may be "Better Place." http://www.betterplace.com/ This company does not make cars. They sell a battery swapping service. They have several international initial target locations including: Israel, Denmark, Australia and Hawaii, San Francisco and Canada. The nissan leaf was to be a part of their system and may be in the future. For now they are swapping batteries on the Renault Fluence ZE. http://www.betterplace.com/ By some measure this might be considered a "full-electric car technology," but to what country are you going to attribute this technology? Shai Agassi, the companies founder and CEO has lived in California and Israel.

The Tesla Roadster is an American company and a media success. It is now selling their cars internationally, but the actual number of vehicles sold is presently just over 1000.1 Their are many lessor known electric vehicle companies that may happily sell you a vehicle that is hardly a production run. For a full production run of a full electric vehicle (BEV: battery electric vehicle) that is fully highway capable in the US we are looking to the Nissan Leaf as a first. Zap vehicles have been built in China for years and sold by an American Company internationally as motorcycles but we might not necessarily put these in the same class as the Nissan Leaf. The same may be true of other of the ess expensive Chinese cars.

I would agree that the Volt is not a "full electric" vehicle, but it is more electric than the more parallel hybrid prius. From a purist point of view perhaps even a BEV is not a pure electric vehicle as it uses chemistry in the batteries. A pure electric might use ultracapacitors for storage or something like this: http://electric-vehicles-cars-bikes.blogspot.com/2009/08/korean-researchers-develop-electric.html

Is it possible to charge an electric car using solar power or static electricity?




njshaw93


These are just random thoughts I had. If anyone was inspired to make anything, please let me know and give me a slice of the profits. Thanks for your time.


Answer
There is a film out that you can see what cars like this (solar). It's about a teacher who inspires her students to build a solar car good enough to compete nationally in the United States and internationally in Australia.

Follow this like to find out about the film.

How do you stop a dog barking all the time?

Hi,

My dog won't stop barking at cars, bikes..everything really. It's becoming a bit of a nuisance for us and our neighbours.

Can anyone recommend a good dog training manual, guide or offer some suggestions themselves.

Someone recommended this dog training course by Daniel Stevens;
http://www.trade-secrets.org/stopdogbarking.html

Has anyone used it and is it any good? I'm always a bit skeptical of all those great testimonials...even with the pictures.

Cheers.



Answer
It sounds as if your dog is bored.

The citronella anti bark collars work for a short while until the dog figures out that when he barks he just moves his head away from the spray. As far as I know the electric shock ones are banned here in Australia.

Before you hand out all that precious money on training go to your local pet store and find him/her some toys to play with. There is something called a Kong where you put food inside of this toy and it takes them hours to get what's inside out.

How can I get help paying my EXTREMELY large electric bill in Pa?




jellabean


My husband just started a new job. We're both in our mid 20's. We have 2 infants and a boat load of debt to pay off plus the regular bills. We're in so much money trouble, it's scary. We need help with our PECO (electric) bill so bad. They're going to shut off our electricity if we don't pay it in full, in 20 days time. With 2 babies to take care of, we can't afford to have no electric or gas. Any suggestions? (and please don't say something cute like get a job or something. i'm asking for help, not sarcasm.)


Answer
This is a vicious cycle problem. I'm in Australia and have suffered the same problem in earlier life. Steps:

. talk to PECO - often if you have to (how extreme is the bill? If it's miles out of whack with normal, explain this to them. It has surprised you and you haven't allowed for it in your budget) - answer above was good

Regardless of what happens there (because you have to sort things):
. try looking for sell-offs (answer above was good). Can you get a cheaper car to run? Televisions, old childrens clothes and toys at a garage sale etc
. try raising the money through non-borrowing means (e.g. an extra job or whatever)
. try charities - are you in a church for example?
. can you get help with more efficient heating and cooling - lots of green groups out there that might like to use you as a 'project'!

You might need to swallow your pride a bit, get this problem fixed and then fix the underlying problems like doing more efficient things with heating and cooling.

How much would we cut GHGs if we all switched to electric cars?




Chem Flunk


Assume, hypothetically, that everyone replaced their gas-powered cars with either electric cars, or plug-in hybrids, such that 90% of ordinary passenger driving was electric-powered. Assume further, pessimistically, that all the electricity for these cars came from a 50/50 mix of coal and natural gas power plants. Would we reduce our net GHG emissions, and if so roughly by how much? (bonus points for sources)
either as a total figure, or as a percentage of driving-related GHGs...
d/dx: can I have a ballpark guess of the GHG reductions? Trying to at least get an order of magnitude here...



Answer
Even within the information you give there is potentially a great variation: Where are we replacing the vehicles. If you are thinking of almost anywhere than the US then the gasoline mileage for the cars would be higher. It is with gasoline mileage that we start. For every gallon used in an internal combustion engine about 19.5 pounds of carbon dioxide are produced (about 154 lbs per 1 million btu .) As a vehicle travels further on a gallon the greenhouse gas emissions per mile will be reduced.

Not only does the typical mileage vary per country but so also does the energy mix used to produce electricity. If you are considering France than 80% of the electrical power is generated with nuclear energy. The Northwest and Canada uses a lot of hydro. Australia like the midwest US is over 80% coal. There is probably no place that is 50% coal and 50% natural gas. The US mix is about 40% coal 24% natural gas 20% nuclear with the balance mostly renew ables. Coal is on the decline and is being replaced by natural gas and renew-ables.

But for the sake of calculation we assume 50% coal 50% natural gas for electricity for 90% of vehicles. What are we assuming as the starting point? Market penetration for the EV in the US is now less than 1/2 of 1%. Do we assume 0% If we are going to present any numbers we need a working population. The US has about 200 million vehicles. More? Less? What will we assume as the annual mileage for each vehicle. The US average is about 12500 but some use 15000 miles per year. European average mileage is less. In some places like Manhattan 80% of the people don't even own cars.

Because you are considering the replacement of 90% of present vehicles there are factors that are not normally considered. It takes a great deal of electricity to refine gasoline. There are estimates as high as 6.5kWh/gallon. http://greentransportation.info/how-much-electricity-is-used-refine-a-gallon-of-gasoline At this rate the EV can travel further on the energy used to refine a gallon of gasoline than an average petrol car (24mpg) can go using the refined product. The EV would be costing no "new" pollution and we would be avoiding all the pollution of the petrol vehicle and the refinery. Refineries also operate 24/7 so eliminating 90% of them would tend to shift electrical demand away from peak daytime to a more balanced usage.

Another factor that is rarely considered is the inefficiency and pollution caused by coal plants that can not be turned off and can only be turned down slightly to for off peak lower energy usage. Coal must be used to keep the boilers warm at night to avoid boiler damage. Therefore at night when electrical demand is less the more polluting coal plants will be used rather than the less polluting gas fired power plants. Overall electric vehicles charging at night makes the system more efficient than without them but at some increase in pollution.

The refinery + petrol vehicle (85% x 15% = 13% efficiency ) is about 3 x less efficient than a coal plant plus an electric car ( 40% x 90% = 36%) and the difference is even greater with a gas fired plant plus an electric car (60% x 90% = 54%) (average = 45%) This advantage is somewhat taken up by the more polluting aspects of coal ( about 204 lbs of CO2/1million BTU http://www.eia.gov/coal/production/quarterly/co2_article/co2.html ) and by the concerns that burning natural gas produces water vapor and mining natural gas introduces methane into the atmosphere (both more potent GHG sources than CO2. Fracking seems to introduce even more methane (primary component of natural gas) into the atmosphere so some attention must be paid to how the energy is mined, drilled, and transported.

Because the calculations tend to become very complex with many assumptions for variables I am suspect of numbers that attempt to prove or disprove the case for electric cars on the basis of some "exact numbers" for pollution issues alone. What we can say with some confidence is that the EV is by itself a zero emission vehicle and will likely involve from 1/3 to 1/2 the overall pollution (including GHG, spilled liquids and solid waste) of petrol vehicles. When we combine the likely-hood of reduced pollution with the increased security and economic benefits the argument for the EV becomes more compelling.
