My friend's PC in water cooled, every component. If that slacker can do it, I don't see why Boeing can't do the same.

Yes, Gorksi, it's a matter of liquid versus air cooling. It's also a matter of passive versus active cooling. As far as we can tell, Boeing is using passive air cooling. There reportedly are no fans to draw the hot air away. Toyota uses air cooling on its Prius PHV, but it is active air cooling -- they use three fans to draw the heat away from the battery's cells.

The solution seems to be liquid vs. air cooling. The article states that air is less dense at higher altitudes and is less efficient in cooling anything even though it's at a lower temperature. Volt has gone to liquid cooling that works. What is Boeing waiting for? Call the GM engineers and find out what they did. A Volt did go on fire a little while ago.

As far as I know, naperlou, the only reason to use lithium-ion is the energy density. Higher energy density means they can cut weight, which is of course always important in aircraft design.

Chuck, is there any reason they just don't go back to a known battery technology?
