I consider diesel fueled engines as dead-ended a technology as ethenol. I don't think development resorces should be wasted on extending the use of fosil fuel in any way. I don't think giving ethenol manufacturers a $0.51 cent tax credit to help them compete in the fuel market place is a good investment for the American public.

What is needed is to expand the generation, delivery, and use of hydrogen for mobile vehicle requirements. Don't harvest the algae for biodiesel, let the algae generate hydrogen. Use it as the basic fuel. You can even run your turbo-diesel on it and get even better milage then you get now.

This is only the beginning of my 'rant'.

Hydrogen may, or may not, be a "tomorrow" fuel.

Biodiesel is something that can be done today. It can use existing infrastructure and is far, FAR safer than hydrogen. Hindenburg, anyone?

I'm not aware of a process where algae produces hydrogen directly - can you provide a link to a source of info for me? Hydrogen through electrolysis is a losing proposition. More energy in than you get out, like ethanol. At least biodiesel is a break-even or net gain.

You can't compare the Hindenburg with hydrogen fuel cells. Please.

And gasoline/alcohol aren't flammable? Give me a break! You're butt is sitting on top of a bomb every time you get in your car/truck.

Back in my gas pumping days, I was selling gas at 1.00/gallon(Canadian), and minimum wage was 3.50/hr.

not too bad, 3-1/2 gallons per hour.

as of this morning, gas is 5.08/ gallon, and minimum wage is 7.75/hour

this means you now work 2.3 hours to get the same 3-1/2 gallons.
or 230 percent higher cost.

any way you look at it we get hosed at the pumps.
A little tidbit for our US friends, Canada sends more oil (crude) to the states than the Arabs do.
The old "adjusted for inflation" argument about gas prices is spouted constantly on the boob tube and is nothing but pro-oil corporation propaganda initiated by those corporations. Repeating that baseless argument is pretty pointless. Gas is far more expensive than it used to be. Hence the pain in the wallet every time you gas up.

What is going to feed those fuel cells, BTW?

I agree that gas and alcohol are extremely flammable. That's one of the great benefits of diesel / biodiesel. Biodiesel in particular is very safe and is essentially non-toxic.

Nobody's fighting.

The "hydrogen is flammable" argument is another one promoted by the hydrocarbons industry.

That said, the hydrogen fuel cell as our transportation savior is a pipe dream. The technology is decades distant. It's just something to keep people from getting too antsy while our atmosphere continues to become polluted and our climate is irrevocably ruined and the ecosystems collapse.

There are decent alternatives. Fuel diversity is one. Including diesel/bio-fuels as mentioned before. Also electric cars, which have short ranges, but which are excellent choices for in-town commuting. And, no, they don't use as much hydrocarbons as gasoline-powered autos. Especially if you live in an area that generates part of their power grid via hydro plants, wind plants, natural gas-fueled turbines, or nuclear power plants. Again, the argument that electric cars generate as much CO2 is an oil corporation lie.

Also, an increase of fuel efficiency in American autos. Tightly regulated and fiercely enforced. Corporations don't seem to want to do the right thing and must be made to do so. An unfortunate truth.

The plain fact of the matter is that pulling even a fiberglass trailer takes a decent motor powered by either hydrocarbons or bio-deisel. Electric power ain't gonna do it. Neither will the pipe-dream hydrogen fuel cells do the job (not for a long, long time). For now, we have to make do with gas-powered internal combustion engines, or engines that will run on bio-fuels. Those are the only reliable choices for those of us who have RVs.

Don't believe the propaganda.

Hydrogen fuel cell power for automobiles is not a technology that will be available for decades.

However, you can run your reciprocation engine on hydrogen today. The only difficulty is fuel availability and an afordable conversion kit.

Why not just add a hydrogen boost system today and increase the miles driven on each gallon of gasoline.

Hydrogen Boost

<---- See my avatar.

It's not a long-term solution, but if the U.S. would just embrace the new technology of high-speed passenger-car turbo diesels like Europe has, it would go a long way toward easing the pain for a while and allowing us to work on a longer-term solution. Fuel that diesel with a percentage of domestically-produced biodiesel, and watch us stretch the supplies that much further.

My 1998 VW Jetta TDI has around 220,000 miles on it and still gets an honest, measured 50+ mpg if I keep the speeds down. Highway cruising at ~75 mph will return around 46-47 mpg. These figures are about the same if you're using 100% petroleum diesel or a blend of 20% biodiesel. Fr that matter, I've run it on 100% biodiesel and the mileage is the same, but it runs a lot smoother and even at 20% it makes the exhaust smell pleasant. This car has also had a performance chip installed in the computer as well as a 2-1/2" diameter exhaust system. it's certainly no slouch...

Keep in mind that this is an [b]8 year old car that carries 4 or 5 people in a very reasonable amount of comfort and has a generous trunk. It does not use special low-rolling-resistance tires and does not have anywhere near the level of complexity of one of the hybrids. No insanely expensive battery with an unknown lifespan, either, yet is still manages to better cars like the Prius in actual real-world mileage.

If you think of modern diesels as being slow, smelly, loud, and hard to start in the winter - forget it. They're not. I don't even have the provisions to plug in my Jetta and I have started it at -20F, the lowest temperatures I have seen here since getting the car. Granted, it did make a little bit of smoke and sounded like a bucket of rocks in a washing machine for about 30 seconds, but after that it cleaned right up and was good to go. It never once gave me a hint that it was not going to start, though. I think a gasser would have had an equally difficult time under the conditions.

Electric cars are nothing more than a very inefficient way to transfer pollution away from the point of use. [b]IF we generated power using solar, wind, or hydro power that might be a more palatable solution, but we don't. I think we also need to embrace nuclear power - there are obvious drawbacks to it, but nuke plants certainly run a lot cleaner than coal-fired ones.
If we are going to continue to run coal plants, the least we could do would be to couple them with algae farms - the CO2 from the smokestack is separated out and fed to algae in shallow, racetrack-shaped ponds. The algae is then harvested and the oil is used to make biodiesel. On a per-acre basis, algae is many, many more times productive than corn or soybeans.

Don't even get me started on Ethanol as a fuel source. Total dead-end. 'Car and Driver' had a very good article a month or so ago about the economics of E85 if you're looking for more info.

Now, if the auto manufacturers would offer us a genuine compact pickup truck with a manual transmission and a turbo diesel, I would be the first in line to buy one. My tow vehicle is a '92 Chevy S-10 with the small 2.8 V-6. If I was towing all the time, I'd say the larger 4.3 would be a necessity. If I could get a 3-liter diesel in it, that would be just about perfect for what I would want it for. Great mileage, and loads of torque for towing.

<sigh... rant off>
Lee - I saw your address as "live free or die" USA - that sounds like our state of N.H. We live in Errol up by the Canadian border - that's why we vacation in Newfy in order to escape the tourists.

There's a lot of talk of hydrogen, but what about other alternatives? While driving through the countryside we've all noticed those barnyard smells Why could we not harness some of that methane gas. We could keep a pig, cow, goat, horse or fowl and produce our onown gas and not have to top up at the local pump. The neighbour wouldn,t complain "cause he'd have his own.

Hydrogen Boost

My first question, after following the link, is "Do you own one of these Hydrogen Boost systems?"

From the website:

Quote:
...a Salesman Authorization Certificate that authorizes the owner to receive a $100 commission or referral fee for the first Hydrogen-Boost System he sells. Sales commissions increase for each subsequent sale. No stock required, no costs, no hassle involved.
Google "Brown's Gas" and you'll find a lot of what I would consider extremely questionable material.

It's very simple - electrolysis requires more energy than can be recovered from the gasses released.

Yep, I live in central NH. Amen on escaping the tourists. It's not bad here before memorial Day and after Labor Day, but fuggetabout it during the summer!

Thanks for the links - I was not aware of this development.

However, a quote from one of the sites:

Quote:
Economic feasibility with regard to algae sets in only when the energy efficiency - the conversion of sunlight into hydrogen - reaches 7-10 percent. But alga in its natural form achieves at most a meagre 0.1 percent. The new 'turbo-alga' has now come up to 1.6-2.0 percent.
...seems to indicate that we have a ways to go, yet.

Turning algae into biofuel can be done today!
