If we don't remove the methane hydride deposits, they will explode and destroy life in the ocean. So to just leave them alone could destroy us. As for the coal-fired power plant, it should use plasma burners to burn thecoal more efficiently and produce solid carbon as most of the waste which can be used for building material. The bruners would be hot enough to burn water that would be mixed with coal dust. I prefer placing nuclear power plants in space so that if there are any problems, we can send them to the sun. Plasma igniters instead of conventional spark plugs could allow us to burn water as a fuel since they would be hot enough to break down water into hydrogen and oxygen. No need for fuel cells. Also, if my stacked flywheel storage system can kinetically store at least 100 watt-hours of energy per cubic inch of material, vehicles could travel hundreds of miles nonstop and only need to respin the flywheels for 10 or 15 minutes back up to speed. If my solar stack ideas work, both the photovoltaic and steam stacks, we could have major stack assemblies in desert regions producing enough electricity for entire countries. To avoid major damage and death caused by hurricanes, I would use fleets of pumper vessels that would chill ocean water with compressed oxygen and nitrogen and feed the water into tropical storms to keep them from forming into hurricanes. If we had had a fleet of 20 pumpers a few years ago, Katrina could have been destroyed and New Orleans could have been spared. Also, the fleet might have paid for itself by destroying just that one storm.
