I get that out of my solar panels, and they cost $1500 rather than $6000, plus they cost nothing to run rather han $75 for 2 gal of fuel.

If I still had my 36' sailboat I'd be thinking very carefully about a fuel cell. The cost is still a little on the high the side but it would certainly have provided enough top up power for extended cruising.

Now, with my Krogen 54, my power consumption has gone up and I'd need two of them to keep me from firing up a generator.

Fuel cells aren't for the 'average' boater, but at a certain point it appeals to some outliers. Our power needs are small, and at some point (after retiring) we'd like to cruise extensively here on BC's north coast where fuelling options can be over 100 miles apart and some channels extend over 60 miles inland.

Solar and wind would help, except for those month long winter rain systems with little wind and 16 hours of darkness at night. Chuck in 5,000 foot mountains pretty much ringing an anchorage and that pretty much screws the solar panels.

Interesting navel gazing stuf...

Looks good to me. Uses any diesel. What more can I ask for?

I just may have to wait until it goes in mass production and the Chinese copy it.

Bit o history for fun....old buddy Andy Andreach head of engineering in 50s-60s for American Cyanamid in CT & team worked years to perfect fuel cell break through technology and both are gone today and I can't recall if achieved that end. But Andy did help me get on the air as Wa1boe at that time...

No crankshaft, no problem: Toyota's free piston engine is brilliant


The future for generators is this. Some have 2, some 1 piston, slides back and forth, air pressure is the spring cushion so the piston does not slam the cylinder end.
It can run on diesel or gas.

Been waiting for an operational FPLG for a long time too.

I guess we got the Faraday flashlight out of the deal so far...
