and a glacier was moving towards a city at 3 or 4 ft per year. Lets say
you wanted to melt the front of said glacier for a distance of 10 miles
across the front of the glacier perpendicular to the direction of
motion? How much energy and what type, perhaps microwave, it works in a
microwave oven, would have to be focused on the front of the glacier to
make it melt faster than it was moving. Of course the glacier not
confronted by the focused microwave energy would still be moving around
the outskirts of the city. Also of course since the glacier is still
moving, the encroaching front is getting deeper and deeper. Of course
the energy and any waste products would have to be non toxic otherwise
what would be the point.
Can we survive an ice age by melting all the ice as it encroaches our
cities? Powering giant microwave transmitters with dedicated nuclear
reactors. Is it totally impossible?
