What battery powered car can go the farthest on one charge? How far will it go on one charge?

water_skipper questioned:

What battery powered car can go the utmost on one payment? How far will it go on one payment? Somebody was making fun of John McCain (one of the Republican presidential candidates) for adage he thinks we can have an gripping car (battery powered) that goes 100 miles on one payment by the appointment. Just from my imperfect memories, I even if battery powered cars may maybe already do that. Am I right, or was I fantasizing?

How much electricity (in kWh) would be needed to produce the hydrogen to power a hydrogen-fuel cell car?

euthopia questioned:

4How much electricity (in kWh) would be looked-for to yield the hydrogen to potential a hydrogen-fuel cell car for the same total vehicle km as one litre of gas can potential a typical conventional car? Take upon yourself:
a.39 kWh of electricity are required to generate 1 kg of hydrogen in an electrolyser
b.The energy content of hydrogen is 143 MJ/kg
c.The energy efficiency of the fuel cells used is 55%, and that of the gripping motors 85%
d.The energy content of unleaded gas is 34.2 MJ/litre
e.The conventional gas car has an energy efficiency of 28%.

Wouldn’t electric cars be a good way to go?

ithacanian07 questioned:

That way we can allocate the end use equipment to remain established and focus the budge to renewable energy sources on the additional end. Public wouldn’t have to worry about their cars life a waste of time in the near possibility if they buy into a equipment that becomes outdated or isn’t adopted at a better extent, you wouldn’t have to worry about building a new infrastructure of fueling stations, and you may maybe tailor energy production to no matter what makes the most implication on the community level as a substitution for of tiresome to break down the total public do the same business.

With new battery technologies it will liable be possible to have a similar array with gripping engines as we do now with domestic combustion engines. Add plug in gripping hybrids that may maybe run on gas, ethanol, and additional bio-fuels to the mix and you may maybe eliminate the tribulations associated with slow recharging.

Sure, it would take time and assets to exchange the current fleet but that would be right of any uncommon fuel. So why aren’t we doing this?
Alldrm: My top is that gripping vehicles allocate customers to be insulated from shifting energy sources. I don’t know what we’ll yield electricity from. You may maybe always payment your vehicle at home with your own solar panel, if you can meet the expense of it that is.
Vicinic: You need to read what I wrote again. You missed something…
acronum70: Did you even read my details? Or did you just see gripping cars and at once wrote that piffle without having any social rank in rank?
acronum: As I pointed out in my question details here is now the likelihood of combining efficient mid-array (200+ miles) gripping vehicles with plug in hybrids that may maybe run on uncommon fuels. This would allocate you to run on electricity for your everyday commuting and shopping, and use domestic combustion for longer trips.

I also talked about biofuels in my question. And yes, here are a number of tribulations with them (especially ethanol from corn, which is exact jabber scientifically speaking).

Reflect before you post.

“HHO” gas injected into carburetor – does it improve efficiency?

rmerch2000 questioned:

I’ve seen alot of material on the internet about using electrolysis to turn fill up into HHO on demand, then injecting this gas into the carburetor (or fuel injector) of your car.It says it’ll draw only 1-3 amps from your car battery, and yet yield ample gas to boost efficiency by 40 percent. Now…I know its impossible to get more energy from something then you place in – essencially, you are using the car’s battery to convert fill up into this HHO gas, then burning it again which earnings you will only get as much energy out of the upshot as you place in…so…HHO gas burning by itself may maybe not maybe yield more energy than the energy you place in it to convert it…BUT…is it possible that the addition of HHO gas makes the gasoline you are putting in your cylinders burn more throughly? In the end, my question is…is any of the material on the internet about HHO gas injected into fuel injector/carburetor to boost efficiency plausible? May maybe the HHO make the gasoline burn more throughly

Who else fears the day of the all-electric vehicle?

Caleb F questioned:

I know I don’t like them for many reasons.
Number one life hybrid equipment has so much more room to enlarge. If all automakers took off on this like they are on gripping vehicles I’m sure our cars would be drastically uncommon. What about diesel- gripping hybrids?
And if you like gripping vehicles so much, what’s incorrect with a plug-in hybrid that does what an gripping car does and then subdue goes the same interval as a conventional car?
Also, who only wants to go 40 miles on one payment?
It’s terrible ample when you’re in a rush and you’re out of gas, let lonely need to wait for your battery to payment.

Animals that could represent hybrid cars?

Carey questioned:

Public respond to metaphors from their Buff up. Deliberate that the chief automobile maker wants to use an animal as an image in their exposure for a new line of fuel-efficient, hybrid vehicles. Take three paragraphs and pick two animals you reflect would be excellent metaphors for a hybrid ad campaign. Now reflect of two animals that would be appalling, terrible, foolish metaphors for a hybrid campaign.

Can you help me with my eco-friendly automotive theory?

Nate Chillin questioned:

Delight hilarity my thought for a second. I had this thought for an eco-friendly car. Its in the end the Ford Fusion only with solar panels covering the car with the fusion generator that is already now built into it (as a substitution for of using gas as a kickstart). The vehicle would gain solar potential while the vehicle is parked which juices the battery. As you handbook down the road, both axles turn, the gears turn for the generator (fusion) storing energy so the car maintains a levelheaded energy source that can be manually toggled between solar and fusion potential treatment. I’m not an sell something to a name, but I reflect at smallest amount some part of my thought may maybe be used in making an eco-friendly, shiny and very cool looking car (5 speed manual, 2 door, seats 4 adults, insightful silver or scrape strong mirror-like clarification with black racing strips, the solar panels are built into the racing strips so that it blends into the top, top surprise potential/automatic facial appearance so that the battery is not drained too much, vehicle uses 6 car batteries and 2 generators ). A second selection is that we may maybe austerely buy the same uncommon energy hybrid or fuel cell
vehicles that are used now in the UK.

Rather than screwing around with basically unproven electric cars, why doesn’t Detroit go nuclear?

The Day after day Elitist questioned:

Now that it seems the automakers will end up in receivership at smallest amount, why don’t we skip the stupid gripping hybrid jabber and build nuclear-powered vehicles? I’m dead serious – it would simple to drop a microscopic uranium hydride reactor in a passenger vehicle. Ford had the nuclear-powered Nucleon thought all the way back in the 1950’s.

Let the Japanese, Chinese, and Germans mess around with batteries and plug-ins. Let them build go-karts that can travel 200 miles without charging up – we’ll have 500-horsepower Escalades that can go a million miles without refueling or emitting a release small amount of carbon, and which would be greatly safer than riding around with 20 gallons of uber-combustible gasoline in a steel tank a few inches off the ground. Just infer what that would to give a new lease of life American industry and the state!

So, do you agree? Is is time to get serious and start building nuke-powered vehicles?
Jonathan,

Microscopic 25 MW nuclear reactors will be on the market surrounded by a few being:

http://www.hyperionpowergeneration.com/about_tech.html

Are you telltale me the same equipment couldn’t be scaled down some more and dropped into an auto?
The Kilted Cowboy,

You don’t know what the hell you’re discussion about. Comparing a new uranium hydride or thorium reactor to Chernobyl is like comparing a Nimitz-rank aircraft carrier to the Colossal. In the possibility, perhaps you ought to educate yourself before donation an unacquainted attitude.

Why not build a car like this?

RobRob questioned:

Place in a very small and efficient diesel or gas engine, that just recharges the battery, and have the car run completely off an gripping motor. This would demand a more powerful gripping motor, of say, 100hp equivalent, may maybe be more tho if de rigueur or to suit the American market.

This would save a lot of consequence by having a smaller engine and boost efficiency by having the small engine running constantly at its most efficient rpm, just providing ample potential to meet the average potential requirement of the car. (Running down the battery a bit below heavy driving and charging it up below set alight driving. The gas/diesel engine may maybe be as small as say 50hp but much more potential would be unfilled if looked-for.

Place it in a very aerodyamic car like a Prius. Make it a plug in hybrid too so you can payment it at home as well. May maybe make it possible to run off E85 or biodiesel as well, but wouldnt be elemental.

This would indeed be much more efficient than even something like a diesel smartcar, which gets 88 (imperial) mpg collective, without the drawbacks on size and potential. And we have hybrids, we have gripping cars and we have cars that run on e85/biodiesel already so its not like the equipment isnt unfilled.
Johnnie – Gripping motors are very efficient really – typically around 90% compared to 40% for diesel and 25% for gas. The battery may maybe be a similar consequence to the one in the Prius and that isnt too heavy.
James – how would it be more pricey than a Prius, they have a generous battery and gas engine too.
Vicky – here are. For model the Tesla roadster has an gripping motor equivalent to around 240bhp, and a generous ample battery to potential it for 250 miles per payment.
Richard – the Prius is really very open surrounded by as it only has a small engine which doesnt take up as much interval. A small generator would take up even less interval. I’d be pleased to travel across America in a Prius (even if it’d be a lot simpler to glide in actuality).
Also richard, excellent aerodyamics would boost the efficiency, making the car closer, use less fuel, and probably quieter at high speed.
Lazyeddie – Americans buy the Prius so this would cater to the same market.
trainboy – i dont see how this would be much heavier than a Prius.
snapdrag – until the array of gripping vehicles increases, along with places to payment them, and the time it takes to payment them, they will only really be matter-of-fact as a second car for the city. By having a secondary fuel source you take out these drawbacks and have a car thats matter-of-fact for a lot more public.
Wolf – The Chevy Volt looks like a excellent top but i cant be with you why it looked-for a 1.4L 71hp engine just to potential the generator. Indeed something around a third of the size would have been more efficient, less pricey, lighter and smaller.

Also, why is it only a 4 seater?? Indeed a 5th seat would boost sales a lot at effectively no superfluous cost? And i cant see why one wouldn’t fit, its the same size as a BMW 3-run.
John – how much potential does a car of the Volt’s size need to sustain an average speed of 70mph on the freeway.

I’ve obsessed a car which only had 54bhp at 70mph and it was doing around 3500rpm. Compelling into account cars only yield their peak potential at nearly the maximum rpm, it must have been using less than 54bhp, ill take a guess at 30bhp. Yes, it was a smaller a car, but i skepticism the Volt wants more than dual the potential to cruise at the same speed.
John – e85 is subdue better than gasoline for the background. Something like 35% less co2 i reflect i read.
And infer E100 was used to yield E100. Out of each 5 gallons bent, 4 would be used to make it, and 1 would be sold. But it would subdue be carbon neutral.
Observably here isnt ample interval in the planet to yield ample for all our cars, and subdue have ample interval for all our food. But as long as its use is kept to a small percentage of the market, its subdue excellent for the background.
Also John, according to wolf below, you only need 20hp
edub – no you wouldnt be better off having the engine potential the car. Why do you reflect a Prius gets better mileage than a Yaris for model, even with the Yaris life lighter.
The engine performing arts as a generator would be able to run at a continuous optimum efficiency eg. 1800rpm, powering the car it would not.
Nata – You gain efficiency as a smaller, more efficient engine can be used, which is able to run at a continuous maximum efficiency.

It will by all accounts cost $30,000.

The prius isn’t that small. In the UK, where I live, its vaguely privileged than average size, and in Japan theres lots of cars much smaller, that seat 5.

The prius can go 100 mph, its top speed is 106. You’d lose your licence if you went 100 anyway.

The prius gets less MPG than an M3 when its life thrashed round a footstep. No one drives like that on the road, and irs not the same as cruising at 70mph.

A generous percentage of the Prius’ sales have been in the US. The Prius is the largest promotion hybrid worldwide.

Why would it need to be widened to seat 5? I’ve been in much narrower cars that seat 5.

word meaning?

Eee questioned:

what does the word “emissions” in the passage mean?

Now, car companines face tiresome decisions. federal sterile air laws demand a fastidious number of vehicles bent each year to have low emissions. what they have bent is the hybrid gass/gripping engine.

in the passage, the emissions that come from automobiles are
a. battery acid
b. combustible fuel
c. drinkable fill up
d. polluting gasses

Why do hybrids use the gas engine for power as well as charging, why not just use the engine to charge the car

MaZM questioned:

does it have to do with the weakness of the gripping engine?
Or is it a conspiracy to use more gas, even in a hybrid?
or does it give for a name unknown (to me ) function?

Re: CNN’s Special /Who knew Brazil (after working only 30yrs on changes) was already energy independant?

Windyloveskids questioned:

We must at once batter to honey ethanol which is 7 era as efficient as corn ethanol.

Bring to somebody's attention MPG Ordinary for automakers – For each one mile gained in fuel efficiency, 50 thousand barrels of oil are saved everyday.

We must already be retrofitting gas pumps & using Flex-Fuel Cars

Are US politicians out of the mimd on ethanol production sources?

jp l questioned:

Why they promote corn and additional grains as sources as a substitution for sugarcanes which have at smallest amount 3X more efficient ethanol? Why use something will erode soil with the need of bounty of fertilizers while sugarcane only demand modest? Are they really for the background or just plain green? Perhaps they really work for fossil-fuel corporations to prevent ethanol efficiency compelling over?

How ridiculous is it that we have to settle for hybrids, when we could have electric cars?

Lovex_Fan questioned:

I recently just saw the documentary called, “Who killed the Gripping car?”. It discussion about this incredible modest car which is powered by electricity. It’s smaller, closer, and gives off NO detrimental emissions. The car can payment at night, and be well ample to get you owing to the day. It can even be used as a GENERATOR for your household in a potential-outage. Well, guess what? GM buys out all the batteries which are used in these cars, which earnings– No more gripping car.

Now public are worrying about global warming, and being paid HYBRIDS!! Figure that? Even even if, we had a perfectly fine car effective for the enviroment until GM recalled them, hurt them and hurt their batteries. No more gripping cars.

Whats your attitude?

What is the MPGE (MPG equivalent) for an electric car that draws 15A 120VDC in 47KPH steady driving?

R M questioned:

Here is a run-hybrid gripping/gasoline car ..

http://www.futurevehicletechnologies.com/

.. that claims to get 275 MPG-E for city driving.

Another vehicle, the Revitalized Battery Gripping Pickup ..

http://www.google.com/search?hl=en&q=low+amp+draw+gripping+pickup&aq=0&oq=LOW+AMP+DRA&aqi=g1

.. draws only 15A at 120VDC at 47 KPH driving on flat roads.

http://www.youtube.com/user/BatteryReviver#p/u/6/S3-YpZ0vYC4

The “Revitalized Battery Gripping Pickup” with its LOW AMP DRAW Equipment can be converted into a run-hybrid by adding a gasoline, propane, or natural gas generator on the car bed and running the genset while operational. Just like the eVaro.

Which vehicle is more economical, using MPGE?

How is MPGE, for an gripping vehicle calculated, anyway?

Did you know that Prius does more environmental damage than Hummers?

dlil questioned:

“Building a Toyota Prius causes more environmental hurt than a Hummer that is on the road for three era longer than a Prius. As already prominent, the Prius is to some extent obsessed by a battery which contains nickel. The nickel is mined and smelted at a sow in Sudbury, Ontario. This sow has caused so much environmental hurt to the surrounding background that NASA has used the ‘dead zone’ around the sow to test moon rovers. The area around the sow is devoid of any life for miles…
All of this would be terrible ample in and of itself; but, the journey to make a hybrid doesn’t end here. The nickel bent by this disastrous sow is shipped via massive container ship to the chief nickel processing plant in Europe. From here, the nickel hops over to China to yield ‘nickel foam.’ From here, it goes to Japan. Finally, the completed batteries are shipped to the United States, finalizing the around-the-planet trip required to yield a release Prius battery.”

£5000 help is not much help towards electric cars?

fcass questioned:

now you can buy an gripping car with the help of govt, can anyone tell me why the govt want to waste all that cash on charging points, when all this tech work must be washed-out on making cars that travel a lot additional on one payment without cluttering our pavements and parking areas make the cars payment themselves with all the habitual car charges its own battery indeed if it can payment a 12 volt-or- 24volt it may maybe be made to payment a hybrid, and go a lot additional than 300 miles come on public get your thought caps on make the cars really green

What really is the greenest car?

iambuf questioned:

Hybrids certainly have the best gas mileage and, as far as I know, some of the cleanest emissions (for gasoline engines), but I have heard that with a life-logic breakdown the environmental trace is much privileged, frequently due to the battery.

I know riding a bike and compelling transit is exponentially ‘greener’ than driving, but IF one had to handbook…

What about export used cars? That is very green from a levelheaded waste side. And if you buy a used car that gets excellent fuel efficiency, like an ancient civic, I have to wonder if that is greener than export a new hybrid…?

My only additional thought is export cleaner burning diesel engines, like some of the new volkswagons, in view of the fact that diesel has historically better fuel efficiency, so if they find a way to hegemony their dirtier emissions (which it seems like VWs did..?) that seems like a excellent selection too.

Any additional view?

Be grateful all!
