FAA says Boeing can fly Dreamliners to test batteries
Federal transportation officials approved test flights Thursday for Boeing's 787 Dreamliner, as part of the effort to figure out why batteries failed on two of the innovative planes that have been grounded for weeks. Transportation Secretary Ray LaHood and Michael Huerta, head of the Federal Aviation Administration, jointly announced the approval, saying the flights would be subject to extensive pre-flight testing and occur over unpopulated areas.

From one that is technically illiterate, I look at the the Tesla electric motor vehicles powered 100% by lithium Ion batteries. To keep those batteries from thermal runaway affecting the adjoining cells, they run coolant past each of the cells. Even some laptops and mobile phones have had problems with lithium batteries overheating. I don't know why the Boeing Company don't run coolant through their batteries.
Dear Friend , not to sound impolite , the cooling system is a part of original design of any equipment . Easiest example is about water cooled car engines and air cooled mobike engines ! In both cases the engine designs take care of heat dissipation and keep the respective engines cool on continuous running basis . But always as a part of initial design , and not as an after thought or retro fit .
Apparantly the original design doesn't work.
So , redesign or a different product(battery)is the only option . No repair work !
I think you are right. If it was just a repair it would already be done. Back to the drawing board.
As I mentioned previously, I make no pretence at being a technically literate or anything near that only thinking of a simple solution, but I am having trouble understanding your reply. Does that mean from what you are saying about retrofits and afterthoughts, that Airbus fitted newly designed wings to the A380 when they had wind problems or did they make a retrofit to cure their problems. I would have thought doing a retrofit as the initial design is faulty would be the natural way to go. I can think of plenty of aircraft that have needed retrofitting to make them safe. Maybe I am misunderstanding your comments in some way. And my dear friend, I to do not wish to sound impolite!
Tell me...I have it on good authority that there are 30 Lithium batteries on a "Dreamliner"
Can anyone confirm this ?
I also understand the batteries are charged at the ramp and not by the engines. Cheaper to use land based power than fuel power. The batteries can be charged by the engines in an emergency ?
