Infinite energy from Seawater
Posted by keelynet on January 30, 2009
In compiling news for KeelyNet 01/29/09, I found the intriguing claim from 1954;
“Free, unlimited electric power from the salty sea may soon replace gas, diesel engines in marine use.”
It’s a brine battery which in his models claimed to produce 1 volt at 3 amperes;
“His latest models, Mamie and the Eighth Wonder of the World, are each 21 in. long with a 4-1/2 in. beam and they weigh 2-1/2 and 3 lbs. respectively. Each produces a little over one volt and up to three amperes of current, enough to drive them through the water at speeds up to five mph. This, as any boatman can tell you, is quite impressive for a working model of that size.”
And his description of how the energy is produced;
“The salt water of the sea acts as a conductor of the electric current flowing between a carbon-graphite positive plate and a nickel-zinc negative plate. This current operates a D. C. electric motor which, in turn, drives the boat’s propeller. The plates are corrugated or grooved to provide increased working area without increasing their overall dimensions. Some of McCabe’s earlier models stalled after a short run due to the polarization or “balancing” of the ions. Eventually this difficulty was overcome and his latest boats have ticked along steadily until the motor brushes or armatures became dirty—a running time of five-and-a-half hours and a distance of some 20 miles. After cleaning they promptly took off again as strong as ever. With stand-by motors and facilities for automatic changeover, there is no reason why such a power plant should not run indefinitely.”
Of course we now extract energy from tides, waves, solar and wind but this one got my attention for a self-running boat. It seems like the idea is worth revisiting using modern technology to optimize the effect.
