Where Is the Laser Sinking the Heat?

If anything goes wrong with a non air breathing high energy density battery or any high energy density energy storage material it simply becomes an explosive and there hasn't been any clever way to get around this fact. A tiny flaw releases some energy and that area immediately heats up to 5,000 degrees vaporizing anything in its way until there's nothing left but a crater.

If the entire battery could be monitored for eruptions of heat, however, maybe a laser could quell the problem in time:

The question is, how and where is the laser dumping the heat?

If it could instantly dump a billion joules 50 meters above the motor vehicle it might be ok.

unlikely

the semiconductor must be dumping it as infrared.

Solar PV will soon drop to 35 cents/watt.

The hold up is the battery.

Even if it did work it would certainly be easy for a terrorist to disable.

A suicide bomber wouldn't really care if it was booby trapped with warning labels.

Then the battery would need to be on the to or outside of the vehicle and the vehicle would need to stay out of collisions.

The only plausible high density energy storage must be air breathing, i.e., a fuel cell, metal air, etc.

"Thus if one applies light from two opposite directions, the atoms will always scatter more photons from the laser beam pointing opposite to their direction of motion. In each scattering event the atom loses a momentum equal to the momentum of the photon."

Even if a laser could quell problems in a lab for short periods of time, you wouldn't want a super cap or non air breathing super battery out on the street as a consumer item.
