10.4 and 11.2 is not a 44% increase. Its a 7.7% increase

11.2*6831 = 76.5072 Kwh
10.4*6831 = 71.0424 Kwh

ALSO a 7.7% increase, so if Roadster was 250 miles now it would be 269.25 miles

This is the list you get when you focus on one specific criteria. Quick everyone buy 10 mpg tanks, it's safe for your dog, and as we all know dogs are more important than humans. While that is sarcastic I know people who are close to believing that.

Have anyone ever sit down to calculate the cost of a Lithium battery for other devices if you were producing them for cars so that the price of a car isn't affected significantly and has 200 mile range.

It is cheaper to buy a new battery (0.10 to 0.30 dollars) for your cell phone then to charge it (when you consider people leave wall warts plugged in and there inefficiencies). Your Laptop battery is disposable daily it has to be so cheap. (1-3 dollars).

There isn't enough platinum in the world for fuel cells and nafion is created in such a complex process it will never be < 300 dollars a square meter according to suppliers. Making fuel cell cars years out.

Mazda and BMW are working on the only tech that is usable TODAY. Not when there is super scalar manufacturing or tech breakthroughs we can't image.

But what do I know. I'm only a Mechancial Engineer in the Automotive Research sector who has actually looked at this rather than believe news stories.

Glah! I don't know why people think this looks good but the styling has no brand image. It's just a random car. The car that car and driver photochopped together a long time ago was better.

Front is is trying to combine a cheap family sedan (ala Mazda 6) with an Aston Martin grill. What was Henrik Fisker thinking?... oh ya, keep the good designs for Fisker Automotive.

At least I understand why Tesla tried to sue! hahaha

Don't worry, It's just some designer thinking he/she is clever. Can you say Rube Goldberg machine?

On a bicycle a dyno/gen/alternator strapped to the wheel or drive will be more efficient. Turbines are 67% max for bladed, then the other losses. 1 Watt may cost 3. Wheel dyno, 1 watt may cost 1.1 in user expelled energy. Keep.It.Simple.Stupid!

Motorcycle. Perfectly good regulated voltage there I think. Duh :P

RTO - New GM paint shops have a way of dealing with this already. Recirculating thermal oxidizer - IE: Paint burner.

Toyota and Honda in Canada doesn't have an RTO, GM does in all new paint shops including Oshawa. It heats ceramics hot enough to burn paint using natural gas. When painting cars less natural gas is used, when not, the natural gas keeps it hot enough. Its good for the enviroment :-)

In the current situation GM moves 160 000 vehicles a month, down from near 300 000 a month, that's easily 3 million a year. Tesla has delivered there 100th! So on a car per car basis the big 3 wants less than 5000 dollars for every car they produced in one year(much less because this has been cumulative issue for years)! Tesla wants 3.5 million for every car its produced to date. Who will affect the working class more.

My money is on giant corporation that affects millions of people indirectly from suppliers to energy. Tesla is a dot on the surface of the earth and just because they have a lot of press surrounding a sports car doesn't mean they will change much. Model S is a 60k car. High class, and not middle can afford that.

Can a high performance electric car be made with off the shelf components - yes, and actually its very easy if you have the money. Enough money will get you a pack, a charger, a big motor and controller and a lotus elise. Its not hard but it does cost money.

Whats funny is everyone things hydrogen is an energy waster. Fuel cell vs battery for efficiency the battery wins. Battery vs combustion engine guess who wins. Depends - There are combustion engines with millions of miles on them. Think a Li-ion pack will do a million miles? How about 200 thousand. No, maybe 80-100 if you are lucky with a big pack and drive frugally (because of the high current causes accelerated wear and heat) that is designed to give a car 250mile range.

Considering that even with a bad economy over a million of cars are sold a month. Thats a lot of batteries that are expensive to recycle in a landfill in a few years. Sustainable? Naw.

Bit of a one liner about hydrogen. Sounds more like he's backing his company position which is expected and then backing it up with a statement saying he's made engines for the last 30 years. Essentially a head of Daimler giving an opinion and nothing more which pushes the current and immediate future cars.

Disappointing, I was hoping he was going to back it up with something.... anything. Nothing new at all or of any substance and not anything that people haven't heard before, but this time in Spanish!

"The cheapest source of H2 still has a retail cost of over $8 per Kg"

Really? My university lab can make it using night time electricity rates at about 70% efficiency, for about 2/3 the current cost of gasoline for raw energy (1MJ gasoline vs 1MJ hydrogen gas). Compressor efficiency varies though, but if you utilize waste heat to do something like heat a home or building then its not a waste. People heard it is $8/kg but it depends on energy source, purity, transport etc. ITM is suggesting to cut out a lot of that.

Lithium based batteries have been mass manufactured for years and are still having a hard time coming down in price, thermal management is the big engineering aspect along with battery equalization. I can't see more mass manufacturing fixing this and it takes away from the convenience of a car, hydrogen won't.

I'm a hydrogen proponent but not necessarily of fuel cells. I think H2 ICE can work considering at night places shut down wind turbines for lack of demand. Fuel cells still have a long ways to develop but littering the world with used batteries that people will not recycle (due to driving up cost of a battery, cheaper to get new lithium). Fuel cell platnium is easily renewable and just the nafion would need to be replaced.
