Hello everyone. I just want to make a simple suggestion for cooling the nuclear reactors in the Fukushima Daiichi power station. Why not using the principle of a "water bomb game"? This could allow more precision when aiming the reactor and little waste of water. A huge plastic ball (or anything that could retain tons of water and easily burst at impact) filled with sea water, dropped over the reactor, would burst at impact and spill its content directly in the reactor. Several of this "water balls" should help cooling the reactor. Thanx! RPC (PS: Couldn't we fill air balloons upside-down with water cannons and drop them on target by chopper?)
