Electric Car Breaks UK Land Speed Record
A battery-powered car has broken the UK land-speed record for electric vehicles at Elvington airfield near York.
The Nemesis, a heavily-modified Lotus Exige which was originally bought on eBay, clocked an average speed of 148mph (239km/h).
The car was designed and built by a team of British motorsport engineers in Norfolk, and driven by estate agent Nick Ponting, 21, from Gloucester.

The reporter it talking too much...
Electric is simply the future.
Oil is way too precious to burn it.
The only problem that has to be conquered is the energy storage.
Batteries are heavy and need quite a time to loaded.
But it is imaginable to have a 'standard' type battery that fits all vehicles that could simply be replaced at the 'gas station'.
Fuel cells with hydrogen are also a way.
But hydrogen is very delicate and would need a lot of technical equipment to make it easier/safer to han More..

@josch
The sad thing is that petroleum will still be needed for the manufacturing and maintenance of an electric vehicle.
It's the same with windmills and solar panels. Petroleum simply cannot be phased out of the equation...

@Ben Cambone Yes that is true.
You have to generate electricity first to run an electric car. But power stations have a quite high efficiency so at the end it pays off.
Also (if the source is to be trusted) 50% of crude oil is turned into gasoline, so you could use 50% of the crude oil in a more sensible fashion.
It is of course true that you can't stop using oil from one day to an other. It is a gradual process. But it will not happen if you don't start in the first place.

True, though I didn't just mean the power needed for manufacturing, but also the petroleum based products and components that are required for production, from lubricants to plastics etc...

@Ben Cambone I see.
Lubricants are ~1% of refinery yield
Plastics are not that transparent to me, but check the source:

@josch
Plastic components, circuit boards, batteries, paints, automotive fluids (including antifreeze), nylon and vinyl upholstery, synthetic rubber and other synthetic materials etc etc. These are from petroleum sources. Moreover, there's the question of what road source the electric car is going to operate on (e.g. asphalt)?

@fido321 i have to ask, why would you want it to go at 110? the legal limit is 70. never understood why car manufacturers insist on making cars that can go twice the speed allowed on the roads.

@fido321 sorry, musta picked you up wrong...
"Its great for me to run about town in, do the 30 miles per day commute to work etc but the long motorways drives will still need to be done with my fellas regular car."
are you good friends with RealityChecker by any chance ;)

i wonder what it's efficiency is. a steam locomotive was 2 or 3%, a petrol engine car about 30%. i would imagine it would be very inefficient at the moment and would only give you about 5 or 10 miles a charge. in saying all that it's good to see i guess.
jeremy clarkson will be fuming so that's an added bonus! lol

@nooneathome Electric engines have a very high efficiency of usually above 90%. However the overall systems efficiency is dominated by the batteries which only have an efficiency of 70% to 85 %.
The problem with the miles/charge is that batteries have a smaller Energy density of only ~1MJ/kg (Gasoline ~40MJ/kg).

@josch thanks mate but what i meant was it's ultimate efficiency. a mobile phone needs something like 20 or 30 times the input to charge from the mains. if the same is true for this car then all you are doing is moving the burning of fossil fuels to power stations. so it might turn out that this car id far less efficient energy wise than a petrol engine.

@nooneathome Mobile phones usually have lithium-ion batteries. These have a charge/discharge efficiency of about 90% (if we trust wikipedia). So if you put in 111 J of energy and you'll get 100 J out. The rest is lost as heat while charging/discharging.
The problem at the moment is mainly the poor distance an electric car can travel.
That is, as I mentioned, because of the batteries small energy density.
See these Wikipedia articles:

@josch i misunderstand me mate. i am not talking about the power usage of the battery and it's efficiency. i mean the over all amount of energy required to charge the batteries in the first place. it takes far more energy to charge a battery than what you get back out.

@nooneathome I thought I got you right way.
Do you mean the overall efficiency of the battery with its construction?
If not, I'm quite sure that what you described sounds very much like the charge/discharge efficiency I mentioned.

Electric cars are great and all, the problem is that advancements in battery technology have flat lined in recent years and we cant get anything with more capacity than lithium ion batteries without resorting to using nuclear materials.

Seems like I remember a vid of a guy with a Toyota drag car that he converted to electric. I bet he would race this fancy pants car for pink slips.
