Hero or Dog

This is going to be one of those hero or dog stories.  If Toyota fails they will be seen as fools, and if they succeed they will hailed as geniuses.  I guess the big question is what volume of air is required for a charge, since that will determine what will be required for a desiccant.

Long haul

I believe that Volkswagen may get this technology to work...eventually. To their credit, they didn't release this as a news item, and made no statements about it, other than the one that was picked up by the press at the Geneva Motor Show. This is going to be a long haul, and I'm sure Volkswagen knows it, which is why they're saying so little about it.

another far out technology

Cap'n, this is another possibility, that has been talked about for a while, that is not ready for prime time.  As you have pointed out, there are lots of technologies that are probably ten years out.  In the meantime, the car companies have to sell cars and meet standards for fuel economy.

Charles, it's already been a long haul - we've been hearing about lithium / air batteries for quite a while.  I wonder if, instead of a long haul, in fact it's a dead end.

I DO hope they make it and come out with an industry-changing battery.

I am also wondering about its practicality - how does the volatility of lithium-air compare with what is currently on the market?

Nancy Golden, from the looks of it, It is still a long way to go because of the unstable nature of the electrode. I guess only time will tell how it will turn out to be. Looking forward to it.

I agree, for now it seems a bit far fetched, almost making the current battery power four times as strong seems a bit ambitious for now.

I agree. With new technologies some form of risk and uncertanity is involved. It will be interesting to see the test data validating the potential of lithium air as suitable replacement for traditional car batteries of today.

I am guessing that test data will initially only be aimed at a workable chemistry and safety data will come later...they may not yet worry about potential issues that will need to be addressed until they know they have a feasible product.

I agree. Once the product seems viable, only then will the test data substantiate's the product's technology as been feasible for manufacturing. Very good point.
