We’re all looking for alternate, better, and more powerful ways to charge all of our gadgets. That’s half the fun of owning all these shiny things: finding ways to actually keep them powered. And while double-A batteries, or any of their brethren, work great for some things, and those AC wall chargers are constantly plugged in, we’re always in the market for something that we can take with us, doesn’t kill our batteries in the process of charging, and can last longer than we probably need it to.


Hydrogen Sailboat 2KW Power System Tested    June 2010

First test run of the Horizon H2000 2 Kw hydrogen fuel cell in the 6 meter (20 ft.) hybrid drive sailboat. The electric motor (Minn Kota RT202/EM 2HP) is mounted on the cavitation plate of the old Evinrude gas outboard. The H2000 is ideally suited to power a 36 VDC battery bank power system. The system is easily installed with a few off the shelf parts and is very quite during operation. This is the third fuel cell system that we have used in the boat and I am very pleased and impressed. I have the best of both worlds, a totally environmental friendly unit and when needed the use of a gas based system at the flick of a switch.
