Technical and financial hurdles have prevented the breakthrough of wave
power as a green energy source so far. U.S. researchers now start with
mobile power plants, ship a new trial.
With the energy from ocean waves theoretically would meet the
electricity needs of the whole world. Could prevail so far none - many
ambitious research projects that have been promised. They were either
too expensive or too inefficient. A completely new concept developed by
the Boston researchers Fraunhofer Center for Manufacturing Innovation
(CMI) on the basis of model experiments and calculations, and presented
in June 2011: "Mobile Wave Energy Harvesting." Ship with mobile power
plants, the scientists want to capture Andre Sharon wave energy on the
open sea and transported to the mainland stored in batteries.
As power plants are retrofitted ships are provided with four to six
extendable arms, located at the ends of which float. At sea these
floating bodies lowered into the water and then move relative to the
hull with the waves up and down. The connecting arms transfer the
kinetic energy of the floating body of a generator on board, which
transforms it into electrical energy. This will eventually be stored in
large batteries.
Because the mobile power plants do not rely on submarine cables, they
can always be used right there, just to rule where optimal wave
conditions. In their calculations, the researchers went out for two
meter high waves. Basically, however: The higher, the more energy can be
gained. And even if it is too rough, the boats simply stay in port. Up
to what range they can work from when they consume so for the arrival
and departure as they gain more energy, yet to be determined.
