hydrogen, ahoy!

It\'s hard not to feel a little ecological
When the first hydrogen fuel cell ship on the Bay of San Francisco slid past the marina of the South Beach Yacht Club at Pier 40, smug, leaving behind a marina filled with huge yachts and sailing boats, the yachts and sailboats burn dirty diesel and gasoline in the engine.
A loud noise from the bow propeller, 30-
The foot green fiberglass water taxi turns left, but once the boat is on, there is little noise in the engine and there is little vibration in the boat.
\"I have never been on a boat so quietly!
A passenger exclaimed.
The ship, designed by the airworthiness system, is not discharged because it has no interior
Internal combustion engine.
It is powered by fuel cells and batteries and requires additional oomph during acceleration.
\"When you\'re on the water, the energy really comes from fuel cells,\" explains Rex Hodge, president and CEO of battery maker Anuvu.
Like a hybrid car, the internal combustion engine charges the electric battery and the boat never has to plug in the power to charge the battery because the fuel cell can do the job.
Away from the Bay Bridge, the boat makes a sharp turn to the right along the cement embankment separating the port from the Bay.
Seagulls, morcor and several brown pelicans hung on the wall, and they didn\'t seem to notice the quiet boat or its manpower cargo.
The ship then circled the Pac Bell Park, across the same waters, and in giant games, the pods of kayaks and motorcyclists tried to capture the home run.
But our journey ended soon.
\"I was told that my last trip was too long,\" the captain apologized.

After all, it\'s just a demo, and on top of that, the fuel for the baby\'s juicing sodium bhumate costs $48 a gallon.
In the past year, hydrogen has been touted more and more
From the global warming caused by greenhouse gas emissions to the excessive dependence of the United States on foreign oil, long-term solutions to all problems.
Until recently, hydrogen was the territory of a handful of futurists and environmental activists, and has even entered the Republican policy-makers.
In January, President Bush mentioned hydrogen in the \"free fuel\" program.
Earlier this fall, the current governor
President-elect Schwarzenegger has proposed that California lay a \"hydrogen Road\" by 2010 \".
The pump delivers zero fuel to a new generation every 20 miles.
Emission vehicles--
An offer that drew ridicule from those who wanted to know where the Hummer was
In the midst of a terrible budget crisis, drivers will find money to pay for bold new infrastructure.
Meanwhile, hybrid cars like Toyota Prius are being snapped up by buyers as quickly as possible.
However, like many great future technology solutions to today\'s problems, the hydrogen economy has a way, and with your attention to it, there are always years, if not decades, then go.
Problems with infrastructure, problems with fuel cell prices, problems with where you get hydrogen, and so on.
It is not clear that the modification of the ship with fuel cells is only the best decision to clean up marine pollution.
There are cheaper options.
However, the momentum of hydrogen seems to be forming, driven by the rising tide of land and sea.
In October, Anuvu began quietly offering fuel cell vehicles to the public. -
A pickup truck with a hybrid fuel cell and battery engine--
Retail price is $100,000.
No one has bought it so far.
Despite the hype and media coverage of fuel cell cars, in fact, the public may get it on the water ---and afford --
This is the first application of transportation technology.
Mary Francis kunani said that San Francisco plans to have a fuel cell ferry on the bay by 2005 to drive from Treasure Island to the city before returning, the marine engineering manager of the city water transport authority.
The project is funded by $2.
5 million federal grant from Congress to try out the technology on working marine ships. Our boat\'s $48-a-
The gallon fuel interacts with a catalyst that separates it into sodium boron and hydrogen.
The fuel cell breaks down hydrogen to generate power, powering the engine.
When a non-toxic sodium boron by-product returns to the dock, it is poured out of the ship.
However, Craig Newhouse, sales director at Anuvu, stressed that so far this expensive fuel has \"no distribution or infrastructure\", noting that the price per gallon has to drop for an effective commercial use.
But he believes it will come true.
The boat we ventured out today is a demo leisure car, not commercial, it can accommodate 18 people, up to 8 people.
5 miles per hour.
The project is funded by the California State University transportation technology business deployment center in Long Beach.
Hodge said the center, in turn, received most of the money from the Ministry of Defense.
New House of the South Beach Yacht Club said: \"Every ship here is polluted like crazy, they won\'t use it in a few years,\" more than a hundred yachts and yachts float in berths.
Until recently, Terri Shore of the blue water network pointed out that the blue water network is a non-profit organization that advocates cleaning ships and ships, various regulations that have made some progress in cleaning up cars and trucks have exempted marine vessels.
\"On the basis of each passenger, the ferry is more polluted than other land transportation,\" said Shore.
The weight of each passenger is much dirtier.
This is because the cleaning rate of cars and buses has reached 97% in the past 30 years.
The marine engine is not controlled.
\"This will change.
Between 2004 and 2007, the federal regulations on Marine ship emissions will come into force step by step.
In San Francisco, the water transport authority has promised to operate the new ferry on a standard of 85% cleaner than the Environmental Protection Agency\'s 2007.
\"By setting strict emission standards, they will be more comparable than cars and buses, so if someone switches from car, bus or BART to ferry, there will be no significant increase in air emissions, \"said Shore.
Today, shipping accounts for about 2-3% of global CO2 emissions, according to James J.
Corbett, Graduate School of Marine Studies, University of Delaware.
But the federal government will not impose any new requirements on most container ships. -
Some of the biggest polluters in any big port-
Because most of them fly under foreign flags.
Even the new standards that have been set will not clean up a lot of diesel
Power boats already at sea.
\"The diesel engine has been going on for decades,\" explains Diane Bailey, a scientist at the environmental advocacy group\'s Natural Resources Conservation Committee.
\"The new standards only involve new purchases, [emissions]on older boats]
Over time, the engine is getting worse and worse.
Therefore, the new standards have no effect on reducing the pollution caused by emissions.
\"Although more government regulation may be needed to really have a significant impact on marine vessel emissions, environmental-conscious boat owners are asking: why wait for hydrogen fuel cells to arrive, when you can now use biodiesel on your existing diesel engine \"air pollution control is an important temporary step for hydrogen fuel cells,\" said the Blue Water coast.
The purest biodiesel-B100 --
Already implemented on existing diesel engines at Ventura port, California;
Elliot Bay in Seattle
West Bay pier in Olympia. ;
Channel Islands National Park on the southern coast of California.
San Francisco plans to build a biodiesel-fueled ferry with a hydrogen fuel cell ship.
But this is not a perfect solution.
\"We tested it with biodiesel, but it wasn\'t as good as we expected,\" said Heidi Massen, a spokesman for the water transport authority.
\"Nitrogen oxide emissions have increased slightly, while other emissions have decreased.
\"Biodiesel ferries and fuel cell ferries will be just two of the 31 new ships that San Francisco will install on seven new routes in the next few years.
The shipping system Sweeney believes that a novel read by a rich man on a boat, technology
Savvy ways to impress friends may also help push fuel cells forward.
\"The rich may push the technology, just as they drive horse-free carriages at the turn of the century,\" he said . \".
He pointed out that the Tamiflu electric boats on Newport Beach sold hundreds of pure electric ships, which were just water taxis converted from fuel cell party boats, designed to be inserted at the pier after a pleasant cruise in the afternoon.
Buyers see the ship as a \"second ship\" other than a yacht or sailing boat to show off.
Duffy, airworthiness systems and Anuvu are not the only companies that are trying to turn wealthy boat people into the possibility of a clean trip in the future.
Australian company Solar Sailor has built several hybrid ship models that combine Solar, wind and power to create a wide variety of zeros
Ship discharge.
Designing alternative fuel technology into a boat has two advantages over a car: the space limit on board is not that tight, which is handy when you design a new power supply.
Unlike cars, ships usually return to the ports they launch to make fuel.
Infrastructure problems are easier to solve.
But the real struggle to control greenhouse gas emissions, improve air quality, and reduce America\'s dependence on foreign oil will eventually remain on the road, not on the water, because cars and trucks account for a much higher proportion of total emissions.
When Detroit concluded that consumers would not choose a limited range of technologies, the electric car market collapsed, despite protests from enthusiastic early adopters.
But a variant on an electric car that does not need to be inserted--
Hybrid electric vehiclegas model --
It has achieved a certain commercial attraction.
Japanese automakers Toyota and Honda are leading the way.
Toyota has sold about 50,000 Toyota Prius hybrids since 2000.
By 2010, combustion/electric engines were used as a regular option for most models, thus providing more fuel for consumers who need larger cars --
An effective alternative to today\'s gas consumption.
