Yeah,

This is way off topic, but a few months back I was speaking with
someone who was into green technologies.

I never did quiet catch his name, but he seemed puzzled why I was big
on promoting Liquid Fluoride Thorium Reactors as
the future of nuclear.

Here is a IEEE spectrum article (the links the article has as
resources are even better) which make the case better than I could.
I am not a nuclear physicist nor engineer. The people cited in this
IEEE article are.

This video is specifically useful in explaining the LFTR position:

I'll spare you the election literature that I have had up for sometime
for a particular candidate in regards to this technology.

Great video. It would be better if we actually would go that way with
the new Nuke plants that are on the horizon.

Y'all already know we can't continue down the current path. Why continue with nuclear energy? It is like riding a tiger. Eventually things go wrong.
Hydrogen is like vatamin c. It is easy to produce. Would it be easier to improve the efficiency of photovoltaic cells or build nuclear power plants to use Thorium?

There will not be as much money in producing H. Everybody will have a little H gernerator on top of the garage. Part of the H produced could with the help of the photo cells liquify H and viola! Stored energy.
 
When the Sun feeds your hot water heater and your furnace, burning fossil fuels for electricity will go out of style.
 
Oh. My favorite part. Because liquid H in a fuel tank is more a prescription for disaster than gasoline, I see huge improvements in the human gene pool.

What's not to like?

Hmm, so H is easy to produce?  I think you need to recheck that.  Yes, we have electrolysis but it is very inefficient so far and there are other issues like degradation of the electrodes.  The best way we have to produce H is to strip it from Hydrocarbons... whoops there we are right back at fossil fuels.

Did you not watch the video?
It's vastly more safe than the current nuclear paradigm.

Saying things eventually go wrong is like saying why bother with
computers, things
eventually go wrong. There is risk in anything.
I'd like to see 1 gigawatt hydrogen plant be anywhere close to as safe
as a LFTR plant.

Actually, I'd settle for seeing a 1 gigawatt hydrogen plant in the first place.

There is a hard limit to any kind of battery or cell.
This hard limit is imposed by chemistry. To mutilate Clinton's '92 slogan:
"It's the energy density, stupid."

This is why for now oil has remained king.
Oil is very energy dense. In fact more so than nearly anything else.

I'd like to see this on a large scale.

Why produce H anyway?  Both the Sun and the Gas Giants are just crazy with it, lets go mine them!

The fastest way to get money for it would be to say that the terrorist
will do it if we don't.
Either that or say that's where Wikileaks staff is hiding.

I was not suggesting photovoltaic cells to make steam to strip natural gas. Of course, it would be cleaner than current fossil fuel uses. Electrodes have been produced in the last two years much improving the degradation. Also there has been success with an alkaline electrolytic solution. If you are using the energy of the sun there is no problem with efficiency unless I am missing something.

The real problem and inefficiency is liquification of H.

If something goes wrong with my computer, my back up will take care of me. If the nuclear plant ... Oh. No biggie. FEMA.
 

Actually, I'd settle for seeing a 1 gigawatt hydrogen plant in the first place.

Then you have missed the point again.

I cannot believe you are that slow. Carefully read the part Where I suggested no grid.

Bill, this group has got into some very heated discussions in the past
but I believe you're stepping over the line into personal attacks.

Even 1GW style coal plants are not safe. The biggest safety problem is not the
generators it is the boiler. Coal plants do 'blow up' and we seldom hear much
about them. All we are doing with any of the nuke scenarios is replace the
coal fire with a nuke. Now I REALLY like the thorium cycle they proposed. It
removes much of the problems of quantity of rock mined to get the
fuel, it consumes
most of the fuel and leaves little plutonium as a byproduct, and the
byproducts get
to near background radiation levels in only 300 years rather than
10,000 years like
the high level stuff we are stoking yucca mountain with.

I will never say that nukes are 'safe', but the thorium option does
seem much more
'atoms for peace friendly' than the uranium methodology we are currently using.

The self scramming aspect of the thorium reactor seem especially
nice/safe to me.

High level energy in any form is inherently dangerous. We just need
to choose the
lesser of the evils, and this one could be economically beneficial as well.

I agree, it is the energy density, especially when addressing
transportation issues.
Tracked vehicles (trains, trolleys, and subways, not armored tanks)
can make good use
of electricity easily. Other than that, petrol will be around for a
long time. Electricity
is good, but petrol took over in the early 1900's and will stay king
for a long time.
Electricity is coming in as a nice also-ran and will get better
incrementally over time.

Hydrogen is nice, but it has some current handling and storage issues,
plus we have
way to many video's of the Hindenburg that people still think they
remember seeing.
Few will recognize the Hindenburg was basically painted with the same
stuff that we
put into the shuttle assist rockets (an aluminum oxide) so when there
was a fire it
went up like a rocket! :) ... still neat films, bad publicity and pop science.

Storing enough hydrogen to power a plant for a few days that generates 1GW
scares me until we get some better technology for managing it. Current folks
that work at power plants would definitely need retraining :)

Time to go burn some petrol and let someone else feed us tonight. ... Later.

Where do you visualize as the source for the hydrogen to power all of these garage-too generators? Most of the hydrogen is already combined with other chemicals (for example, combined with oxygen to make water), and you have to out as much energy in, to split out the hydrogen, as you will get back later when you burn the hydrogen. In fact, as no process is ever 100% efficient, you have to put more energy into separating out the hydrogen than you will retrieve later. So, hydrogen is a way of storing energy, not an actual energy source.

No, However, the people giving this presentation at Google aren't
exactly nobodies in the nuclear world.
Additionally, I have shown it to friends who are/were nuclear
engineers at Oak Ridge.
It checks out. If there are factual deficiencies in this video, please
point them out.

In the long run we will need a sustainable base load energy source.
I have no missed any points. We are talking about different energy usages.
Thorium could be an answer for muni or industrial power needs.
BTW 1 gigawatt is not some magical number. There is a reason why I am
specifically targeting that energy quantity. Hint: Base Load.

It has a lot to do with it. Again I am not a Nuclear physics or Engineer.
I am not even an electrical engineer. However, I do know addition.
I have yet to see how Hydrogen can be a baseload power source.

My whole point is base load. period.

How does this address base load?
If you have to resort to ad hominem attacks then it is merely a sign
of a weak argument.
I get the sense that some individuals may be financially invested in
Hydrogen, thus the animosity.
Just Saying (TM).

I have already disclosed my interest in Thorium and LFTR. :-)

I do love how many of the 'commercial fuel cells' use methane run
through a catalyst as a source for their clean hydrogen. Of course
they let the CO2 byproduct free into the air. :)

Now there is something we could do, is to use Nuc energy to combine
CO2 with hydrogen and put it back into the pipe lines. This way it
will temporarily sequester the carbon until the new natural gas
(methane) is burned. And we already have an infrastructure in place
to transport natural gas fairly efficiently.
