First Solar Powered Speedboat
"It is not too often that we associate solar-powered with anything fast and or furious, but perhaps it is time that we start. The Czeers MK1 is a 10-meter vessel covered in photovoltaic cells that is capable of hitting speeds of up to 30 knots (55.5 km/ph to you non-nautical folks out there). While there are certainly faster boats on the water, those tend to use obscene amounts of fuel.
The solar-powered Czeers MK1 is naturally going to be a lot quieter than its gas guzzling cousins, which would make it great for sneaking up over fish (though there is limited space to put them if you catch them. I would like to see a similar model with little bit more space for passengers, even if it did mean sacrificing some speed. Speedboats are so limited in what they are able to do, but if this had a little extra space, it could do so much more."
