Solar energy has generated a great deal of interest as a potential source of alternative energy. One of its drawbacks has been the limited capacity of its use in regions in northern latitudes and those with a propensity of inclement weather. However, a new venue is emerging that can make solar energy practical–on the water.
The concept of solar-powered boats is grounded in some sound basic principles. Cover on the water is minimized, of course. The reflective quality of water adds to its practicality. The concept has taken hold with the creation of the luxury yacht, the Turanor.
Looking more like a space ship, the yacht is powered entirely by solar power. A diesel fuel back-up ensures the ship can reach its destination in the event it cannot properly recharge its lithium batteries. The yacht benefits from technology of a different sort as well, with software to navigate the boat to sunny locations to maximize energy production.
Another Swiss company called Grove Boats has also explored the use of solar power with its line of Aquabus models. These eco-friendly boats have seen service in several European destinations, including in Venice as water taxis. America-based company, Light On The Earth Systems, has worked on plans for a solar-powered live-aboard catamaran.
The technology at this point is still in its infancy. Solar-powered boats that have been produced are well out of the range of individuals for personal use. The Turanor, for example, has a price tag of $20 million, while the Aquabus prices out at $200,000.
The hope remains that investors will see the opportunities that solar energy may offer for the boating industry. Considering the high fuel cost on the water, solar-powered boats pose an attractive alternative for the prospective boat owner.
The advancement of technology in this field shows the potential that alternative sources of energy have to offer. The National Marine Manufacturers Association estimated that there were almost 17 million boats in the United States in 2001. The sportfishing industry generates more than $125 billion for local economies. Clearly, continued development of solar-powered boats would find a ready market able to make the eco-friendly choice.
