Why are fuel dock prices so high?

Their 2008 product is already spoken for. Their goal is to mostly sell to municipalities which could create several farms on the outskirts of a city. These are cheap and very low maintenence.

as for batteries, EEStor in texas allegedly has some kind of super capacitor that should allow 5 minute charging and 300mi automobile range (if household wiring is improved). They have partnered with Zenn motor company of canada, and Lockheed has signed rights to use them exclusively in military contracts.

these things are just around the corner! I wouldn't worry too much about oil.

I think it's fair to be skeptical of Nanosolar's claims until technical specifications are made available. I do agree that their design philosophy (focus on reducing cost rather than increasing efficiency) is the correct one. I also agree that carbon nanotubes are the correct route.

While solar cells will probably increasingly top our suburban homes and bimini tops, I do think that for industrial and urban purposes, nuclear is the way to go.

Absolutely. It doesn't matter if there is a 10 year supply left, or a 200 year supply left. Or even unlimited. Why not look for something that will be cheaper? And cleaner. And if the byproduct is that we don't have to worry about whether global warming is a reality, so much the better.

I don't suppose you want to PM me with a reference (from either a textbook or a journal article) for that claim?

Anybody who wishes to be schooled in climate science may PM me.

Below is the copy.
I am asking my resource for the document but won't post any more because of the notice of thread drift from GMac, even though Gord added his little bit afterward.

I've already addressed the reason for the CO2 'lag' (which your graph supports, BTW). I want a reference for this claim;

If every car and truck on the planet stopped tomorrow the amount of CO2 produced on this lovely earth would drop by an estimated 0.02% (that's right, 2 hundredths).

Feel free to PM me. Why not collect your favorite three denier arguments, PM me, and we'll see if they stand up to scrutiny?

Sorry.
I won't start a PM "discussion".
Perhaps this could interest you.
Global Warming Debate - SailNet Community

[anotherT34C]

I don't care about what is posted at sailnet.

And it's an open offer to anyone. PM me any three arguments, and we can see if they stand up to scrutiny. I promise to be nice.

The please keep on track suggestion is a reminder to not get into politics. We do not political argument and dribble here.
Discussion of global warming, as long as it does not become political, is fine and relates to us as a cruising community because it directly affects all of us worldwide.

That graph posted is incorrect and has been since proven to be so. The Co2 lags temperature change and over history, that lag has been shown to be as much as 800yrs. The lag what it represents has since been proven to be the release and absorbtion of Co2 from the heating and cooling of the Oceans.
The earth's history provides information that the Earth was once much hotter than now and also much cooler than now. And both extremes never brought the end of life.
There are huge holes and flaws in the theories and some scientists are now becoming much more vocal about the model that has been laid before us, as being flawed.

[anotherT34C]

Alan, the 'end of life' argument you refer to is a straw man. Show me the journal which claims life will end. You won't.

I've addressed the lag. For glacial/interglacial cycles, the initial warming is due to a periodic lining up of orbital motion and rotational obliquity. This causes a series of 'super-seasons' in the northern hemisphere, where most of the land mass is. This releases CO2, which then greatly enhances and extends the warming. From this model one would expect roughly (there are other confounders, but milankovich dominates) a saw-tooth pattern of heating and cooling.

For geologic time scales, the climate is dominated by the continent configuration. This is why the Earth was much hotter or colder in the distant past.

[anotherT34C]

BTW, there's certainly room to argue exactly how the Milankovich cycles cause the CO2 to be released (there's some debate whether it's a northern or southern hemisphere thing, or some feedback combination). The correlations however, are pretty much indisputable.

The planet can't be that bad. Why? Because the hypocrite pot smoking Greenpeace hippies have no probs consuming millions of gallons of fuel while running silly protest circles in the oceans. Cynical – me??? Where's the French navy when you need 'em!


OK, rant over, now back to boating


FYI, below is a pleasure troller that has circumnavigated via the southern ocean from Canada. She's 52' & consumes 1.3gph @ 6.5kts (0.2 usg p/nm) with a total range of 5,000nm on 1,000 usg using a single 55hp diesel. Either go long, narrow & light (or deep but a bit slower or more hp).

Thanks for the links. I like it.

This is a good inspiration for me. A smaller version of this is what I'd like. Just couldn't afford. Maybe if they start building like this commercially, in 10-20 years I could afford a used one...

Perhaps we should open a "Submarine Forum" on CF. Aren't they supposed to be very economical to push when submerged???

It's a southern hemisphere thing and as a person who lives 1deg15min north I think we should just cut the southern hemisphere loose (with all it's convicts and all and send it off on its own somehere.

Where is my thermonuclear hacksaw?

Dan - Here at the future end of the earth...

[anotherT34C]

But that's where all the water is, man! The N.H. has vast areas of permafrost, that're not so perma these days. Let's hack that hemisphere off... just lemme know ahead of time so I can make my way south.

Sail (usually a useless rag, IMO) has a shorticle this month about Steyr's flywheel hybrid. Might be a bit of system complexity I'm willing to put up with.
