Cyclones are a deadly problem along eastern Asia, killing dozens yearly. Their lifeblood? Warm ocean water. Which is exactly what Japanese inventor Koichi Kitamura wants to fix with subs that would pump cold water to the surface, killing storms dead.
When seas are between 25C and 26C, cyclones are able to grow in, boosting their ravaging power as they head ashore. But Kitamura's subs - only existing as patents, for the time being - would slip beneath the rampaging storms and then use 20m tubes to pump cold water to the surface, halting the cyclone's progress (or at least weakening it). Kitamura claims a fleet of 20 such subs, pumping 480 metric tons of seawater per minute, could reduce the temperature of over 5600sqm by 3C - enough to take down the storm.
