Perhaps EV affordability will shake down this way: Fuel Cell vehicles for the rich because of higher fuel costs; Battery EV's for the common person with only a 100 mile range, but less expensive to run. I could live with that.
Now I'm wondering if this might also be true of Zinc?
If the math works out in favor of super-capacitors, I wonder why Honda just switched from capacitors to L-Ion batteries in the FCX Clarity?
I wonder if they've tried soaking it in ocean water?
Does this mean all electric cars will have a 10-40% range increase next year?
I'd be curious as to an estimate of how long it might take to bring this technology to market.
Toyota produced the Prius at a loss for awhile. It turned out well for them. In the small numbers a new concept is sold at, I suppose it's hard to make a profit. Perhaps MBZ shouldn't try to make a profit from the start.
The good thing about capacitors - they can deliver a lot of power very quickly even if not for very long. They should be useful in diesel-hybrids and other high compression engines that take more power to start.
I wonder why an automaker can't make similar advances with a truck? Whoever is able to make a 30 mpg full-size truck will own the market.
An electromagnetic self-compressing tank is an idea that hasn't been explored. Available current at a filling station can expand a tank made of a conductive material. Once the tank is filled and the current removed it can shrink and compress the hydrogen in it.
I wish they would specify the cost of each level of these fuel cells. It would be much easier to get a perspective on how far along they are.
Yes, I'd like to hear more information about this. They might as well include all the parameters.
I'm an amateur at calculating the Watt Hour density. My probably imperfect calculations result in 1.6 KWH per pound. 32 KWH for 20 pounds?
If there was ever anything that could convert wood in excrement, it's termites. Take it from me - I lived in Hawaii for a few years. Termites can eat a building right behind you as you're erecting it.
Furthermore, if the big 3 want to return to selling large pickups and SUVs, make them run on CNG. We'll be back in road hog heaven.
I would prefer to see NG pickups. Pickups are the perfect vehicle for CNG. They have plenty of room under the bed for tanks.
I don't understand how 10% efficiency is very good. If you take a solar panel with 20% efficiency and use the electricity for water hydrolysis which can yield a 50-80% efficiency, you should reap more than %10 efficiency.
This is very interesting. I'm happy to hear so many companies are working together to find a solution to solve the problems associated with the limits of fossil fuels, pollution and global warming. It must be difficult to guess the best places to invest in this time of rapidly advancing technologies; super capacitors, battery chemistry, and fuel cells. What is going to win? Only time will tell.
I guess the question I have is what does it cost to produce a gallon of gas now and what will the cost be at volume?
How will our car companies ever compete with a country whose people only earn the equivalent of $3.75 per hour?
The bus situation is already being handled by natural gas. I doubt any battery/ electric system is going to be as economical. I could see using a Bloom energy fuel cell to power an electric bus. Still using natural gas though. I keep waiting for the big trucks to get onto natural gas. Perhaps the recent breakthrough in graphene supercapacitors will make electrical storage more reasonable for all transportation applications.
If I remember correctly, Iceland has almost unlimited electricity potential from hydro power. Battery technology is in early stages and very expensive. Fuel cells similarly at useful but very expensive. It seems to me, being as hydrogen can be created from water and electricity, Iceland is in a prime position to burn hydrogen in internal combustion engines. The only additional expensive item would be the high pressure storage tank. That on it's own won't increase the cost of a vehicle very much. It seems to me Hydrogen/ICE is good interim option here in the US as well.
I suppose you wouldn't actually need as much capacity with a storage device you could refill instantly. 6 Kwh or so might be enough for people that live in town.
Spectacular of course. I'd be curious to hear about the projected cost of this capacitor.
I wonder if wind power generators could be configured to capture carbon from the atmosphere?
