Re: solar (photovoltaic cells) on boat - Your opinion
There are some new solar technologies being developed currently that produce more energy than the old silicon cells of years past. There is a company called Open Energy that is developing a more efficient Photo-voltaic system. It is being intergrated into roofing materials as well as very thin films. There are also collectors that intensify the suns rays which in turn, heat water to produce steam for turbines. I think this all out of the reach for boat propulsion right now, but I am sure it may not be too far reaching for the future.
