How does a laser light keep a hurricane from moving please o wise one.

She didn't suggest the laser light would keep the hurricane from
moving, but rather break it up. You can break something up while it's
still moving - witness a thrown glass bottle hitting a wall, or a
hurricane crossing cold water.

The outstanding problem with Barbara's idea is the lack of suitably
powerful lasers, not the basic idea.

1) Hurricanes are heat engines that are sustained with specific air and
moisture flow patterns.
2) Lasers can heat air, and can definitely heat water vapor (as found
in clouds), thereby causing expansion and flow.

If you started generating hot spots where a hurricane needed cold areas
for proper hurricane-type circulation then, yes, you might break it up.

But then rude reality intrudes: the most powerful available lasers
might as well be laser pointers compared to the amount of energy
required to heat cubic kilometers of air and megatons of water vapor.
Nuclear bombs may not be adequate (and they'd annoy the EPA more, too).
