Jumping jumbles of water droplets!

Jumping jumbles of water droplets!  Scientists have discovered that under the right conditions, water droplets “jumping” off a hot surface can acquire a positive electric charge.  This has at least one practical application: increasing the efficiency of the condensers in large power plants.  The increase in efficiency occurs because droplets of already-condensed liquid water will leave the condenser's surface – and stay gone – leaving more surface area exposed to the uncondensed steam.  There's also a speculative use: creating electric power.
