Fisherman, dont be an idiot, although it is already too late for that. Receiving payment for IB services in Dec 1998 and Feb 1999, is ancient history, and the entire world knows that. What do you think you are scooping the readers of this thread?

Fuel cell boats: They?re coming By Liz Evans
WORLDWIDE
Oftentimes, new technology trickles down to the marine marketplace from the auto industry. But that may not be the case with low- to zero-emission fuel cell technology.
The auto industry recently turned to fuel cell-powered engines, which produce electricity through a chemical reaction involving hydrogen and oxygen, instead of traditional battery-powered engines, as the technology of the future to replace the internal combustion engine.
And the auto companies plan to move fast. Japan?s Toyota Motor Corp., for example, hopes to bring a fuel cell-powered electric automobile on to the market by 2003.
The auto companies also involved in the marine business, such as Toyota and Honda, are focusing their fuel cell development efforts on their core auto business. However, instead of waiting for the technology to trickle down to the marine sector, some small "boutique" research firms are working on fuel cell applications specifically for the commercial and recreational marine industries.
Alkaline versus PEM
There are two types of fuel cells currently being researched for marine application.
Alkaline fuel cells, which helped American astronauts reach the Moon 30 years ago, are one version.
Proton exchange membrane (PEM) fuel cell technology, currently the auto industry?s choice, also is being pursued for marine applications.
One company involved in the effort to develop fuel cells for marine applications is the UK?s Zemar Ltd., which is focusing on alkaline fuel cell research.
Alkaline fuel cells were written off by many manufacturers after being criticized by American space program scientists years ago. However, Zemar executives believe the company?s decision to continue working on alkaline fuel cells eventually will pay off, says Stuart Laycock, business development manager at Zemar, the marine division of alkaline fuel cell producer ZeTec Power.
Even though the auto companies are looking to PEM fuel cells, not alkaline fuel cells, Laycock believes alkaline fuel cell manufacturers will benefit from the exposure the auto companies are providing to the fuel cell concept.
Zemar is targeting the commercial side of the marine industry first because it believes the commercial sector, where profit margins are under intense pressure, will accept alkaline fuel cell technology before the recreational sector, Laycock says.
However, he predicts that stringent environmental regulations or widespread media exposure eventually will push fuel cell technology into the mainstream recreational boating marketplace. And that time may not be so far into the future. Laycock cites strict environmental regulations in Lake Tahoe, Nevada, USA and Ghent, Belgium as evidence that tolerance for internal combustion engines may be waning.
Operating cost is less
Zemar?s fuel cells currently cost about 15 percent more than comparable diesel engines, but the operating cost of fuel cells is much lower, according to Laycock. Fuel for Zemar?s fuel cell costs only about one third as much as fuel for a comparable diesel engine and maintenance costs also are lower.
Consequently, the higher cost of an alkaline fuel cell should be absorbed after five years of use, possibly less, Laycock says.
ZeTec already has built a prototype taxi and van using its alkaline fuel cell technology and the company is working on a boat prototype to be completed by the end of this year. The boat will be 7.6 metres long and trailerable, so it can be pulled to various locations for tests and demonstrations.
But even if the boating industry accepts fuel cell technology, it could take more than 10 years to install the infrastructure needed to support widespread usage, according to Bob Young, manager of special markets at Honda Marine.
The infrastructure needed for marine applications may take less time to develop than that of automotive applications, however, says Walker of DCHT. Fewer fueling stations are needed for boats than for cars.
Infrastructure also may be less of an issue, at least for boat operators, if America?s Powerball Technologies and other companies like it are on track with new fuel concepts. Powerball is developing a pellet-like fuel that can be stored easily and forms hydrogen when mixed with water. If the project is successful, the industry of the future may see the reliance of boat operators on fuel dock locations come to an end.
Meanwhile, the US Department of Energy has selected low-power PEM fuel cell manufacturer DCH Technologies (OTC: DCHT) to be part of a team of companies that will explore the feasibility of marine application of fuel cells. The study will not be restricted to PEM cells as one of its goals will be to conclude which form of fuel cell technology is most appropriate for the marine industry.
Ship manufacturers, boatbuilders, and engine and propulsion system manufacturers are invited to participate, according to David P. Haberman, vice president of technology of California, USA-based DCHT.
"The marine engine market is multifaceted, and it is our mission to ensure that fuel cells used with electric motors become a competitive part of the maritime industry," Haberman says.
The initial phase of the study will be directed at commercial shipping and military applications, but it will lead to the exploration of other applications, such as retrofitting ships, says David Walker, president of DCHT. If the technology proves viable in commercial shipping, he says it probably also will work in recreational applications.
Fuel cell-powered boats
The use of fuel cell technology might lead to changes in boat design. Fuel cells themselves will not require special hull designs, but the hydrogen fuel used by fuel cells is lighter than gasoline or diesel fuel, which suggests that hydrogen-powered boats could be designed in innovative ways, according to Haberman and Walker.
Fuel cell development is a continuing process. Those interested in following advancements in fuel cell technology can watch for new developments and demonstrations at the International Fuel Cell Conference 27-29 October 1999 at Lake Tahoe, Nevada, USA.
