I brought this odd concept
to the groups attention since I do believe in innovation and want inventors to be successful.
I can relate back to my own experience and knowledge of who turbines work
I am thinking about the motion I experienced on my own trimaran
. Yes in a fairly substantial sea state the bow of each ama experiences rather big vertical movement. If upon each downward thrust water
entered the forward section of the ama I can envision a few tons of water being picked up and released via a turbine that makes electricity. However, it would take a beefy forward structure to accommodate the weight of the water and equipment
To save weight gain, the alternative I can envision is to design a portion of the forward ama like an upside down cup that traps air. On the downward plunge air would be pressurized and released via a turbine. On the upward motion air would be drawn back into the cavity and the turbine spun the other direction. The problem I see here is the amount of energy that can be derived from this oscillation in air flow would be hardly more than the energy of a single
ceiling fan. The turbine mass would be very small to stop and reverse on each wave.
The sails shown would help defeat energy generation by tipping the vessel onto the leeward ama and holding weather
ama higher. This doesn't appear to be the type of vessel that would fly an ama so there would still be some net generation.
Overall however, I see sails plus six wind generators and solar
a much better way to gain a combination of wind and electric
power which seems to be the intent. One wind generator
on the top of each mast
and two on each ama would provide far more power. Solar
on the roof deck
However, again my own personal experiences again come to play and I know they will want to air condition the passenger cabin
. Any electrical
production from wind and solar would be better utilized to offset fuel burned in a generator than propulsion.
And thanks to the reader who pointed out that at best perhaps the article is more appropriately written that the combination of both wind and wave effect would offset 20% of typical propulsion expenditures on fossil fuel alone.
