300 watts and only 1.5 knots ~ A Canada revolution
Canada's first ever hydrogen fuel cell sailboat has been unveiled to
the world, a completely green sailing machine that completed its first successful voyage late this summer. The prototype's creator, Jim Harrington, equipped the sailboat with a 300-watt Horizon fuel cell system with the hydrogen supplied by NRC in Vancouver and the only by-products of the operating fuel cell being heat and water. "This is history being made. It is that significant," commented Harrington. Noting that Canadians are on the brink of a hydrogen revolution, Harrington said, "Every so often in history, there's a convergence of where technology and the supply of parts necessary to start a new age occurs." Harrington's early calculations suggested the sailboat could reach 6 knots under fuel cell power, but his tests revealed a top speed of just 1.5 knots. Future tests will incorporate larger fuel cells. Harrington is working with iGreen Technologies to develop more fuel cell technology products and it is thought that one of their plans is to put together fuel cell kits priced at $4,500. |

@d55g2000hsg.googlegroups.com: Harrington's early calculations suggested the sailboat could reach 6 knots under fuel cell power, but his tests revealed a top speed of just 1.5 knots. Future tests will incorporate larger fuel cells. Just like cars....there's no place to STORE super-high-pressure hydrogen gas bottles that weigh too much, is there? If you took out the diesel fuel tank from your sailboat, the little one that runs the diesel, and replaced it with hydrogen cylinders, how far would it travel on gas stored in the same space? Will it go 20 miles? at 1.5 knots that's over 13 hours. Will it produce full power for 13 hours on cylinders that take the same space as the diesel tank in a sailboat? No, it won't, and never will, no matter how greenie feeley good it is. Then there's this other problem: http://www.hydrogenassociation.org/n...92h2future.asp "At $4/gallon for gasoline, hydrogen’s break-even cost is $8/kg." "Renewably produced hydrogen and oxygen would be cost competitive with gasoline at about $6 per gallon." http://local.google.com/answers/threadview?id=704915 "The price of hydrogen gas in steel cylinders costs about $100/kg." At $100/kg, you could run a sailboat 1.5 knots for about the same price as buying diesel for a SHIP! The ship has bigger heads and lot more creature comforts. Can you say "crazy" without laughing?

No wonder they didn't reach their goal of 6.5 kts. They need at least 20x more power, and then there is the hydrogen generation or storage problem to be solved. |

Couple or three years ago, I read an article about a fuel cell powered Duffy launch with an experimental system that produced hydrogen from seawater as needed, through some kind of chemical process. I wonder what became of that? |

I wonder what became of that? Ran out of fuel? Seriously, if a chemical has to be carried onboard and is transformed thru some process (perhaps even using seawater) to produce the hydrogen to be consumed in the fuel cell, then what is that chemical, other than a fuel? Some examples of such a fuel come to mind: sodium, potassium, calcium. As with anything associated with the "hydrogen economy", spend some time researching how these substances are produced. bob s/v Eolian Seattle |
