I'm a lifelong boater with a career in solar energy R&D and teaching solar energy engineering. 15 years ago I started making experimental solar electric 20 boats. 40 foot Solar Sal traveled from the Hudson River to the Niagara River on the Erie Canal to pickup 4 tons of cardboard and deliver it to a paper mill for recycling into paper, a 100% solar powered 750 mile round trip recycling trip. 44 foot Solaris is the first USCG certified commercial 100% solar electric tour boat. Patent Pending.
