$this->bbcode_second_pass_quote('TWilliam', '')$this->bbcode_second_pass_quote('outcast', 'T')he nice thing about energy is that there are many sources. :)
Not any practical, readily transportable ones with anywhere near the 25,000 man-hours per barrel energy equivalent of oil, however...

Nope

Short term there's methane, long term (if we can work out the storage issues) there is also hydrogen combustion (or fuel cell).

That being said, if it is absolutly necessary we can still go with lithium borohydride

And a nice comparison chart for fun

EDIT: And here is yet another possibility, maybe it isn't quite as good as oil but it should still be adequate for most needs.

$this->bbcode_second_pass_quote('mgibbons19', 'T')his hit me a while ago as well. After a while, one does get tired of the recycled discussions, as well as some of the perennially stupid arguments, like why SUVs suck or don't suck.

In the same vein, having been on the board for 4+ years now, I realize that this is not something that is going to hit one day and the whole world fall apart. That doesn't mean that we don't have a very serious problem, just that history doesn't happen on my timeline, nor does it necessarily happen quickly.

But, I still respect many of the posters, and there's often (certainly not always) some decent discussion surrounding current goings on. I do wish it was a little easier to sift through the bigfoot sightings to get to the good stuff, but it is what it is.


There was a big foot sighting???!!!

By the same guy who said this?

$this->bbcode_second_pass_quote('', 'I')n effect, the world is teetering on the brink of a Greater Depression because there's not enough $30 oil to go around anymore. So here's the solution: We could reduce the price of oil just by reducing demand. If the world could be satisfied with the amount of oil that can still be produced cheaply ($30 is an arbitrary figure - by now $130 oil sounds cheap), then the price would fall to that level.



That was written last summer before the oil bubble burst. If the world is on the brink of a Greater Depression, it is not because of oil prices it is because there is a horrendous amount of bad debt in the system that is being de-leveraged.

TWilliam said there was nothing with as much energy density as oil (excluding nuclear for obvious reasons), and I found something that has a GREATER density, yet you simply dismiss its potential since it isn't in one of your books but is in a "worthless" wikipedia article.

Is it an energy source or transfer medium? It is important to observe this distinction. If it is a source like hydrocarbons then it may be viable. If it is an energy transfer medium like hydrogen, it is a non-starter.

There have been several recessions that were preceded by high oil prices. Now we have another. Is this just coincidence?

I don't dismiss the potential of alternatives. I merely state that they will be (a) much more expensive than what we're used to and (b) incapable of yielding as much energy, in total, than we've "enjoyed" in the FF era.

It was originally researched as rocket fuel. To make it work there would need to be some additional R&D, namely designing an ICE that could use it, but it certainly does have potential.

But even so, for day to day city driving we don't need something this powerful, the entire point of the PHEV was to be able to do your day to day driving while using little or no gas.

$this->bbcode_second_pass_quote('', 'T')here have been several recessions that were preceded by high oil prices.


Other than the one in the 70's that was caused by an artificial shortage (ie, embargo), name one.

$this->bbcode_second_pass_quote('', '(')a) much more expensive than what we're used to and


If we were to use a direct borohydride fuel cell (not to be confused with the lithium borohydride i mentioned earlier, different things), while it not would have as much energy as oil for most people doing their city driving something like this is enough. Here is the cost of the fuel:

$this->bbcode_second_pass_quote('', 'S')odium borohydride costs US$50 per kg, but with borax recycling and mass production projected prices for the fuel are as low as US$1/kg


The reason it is expensive now is because currently it is not mass manufactured. At $1.50 per gallon, gas costs $0.6 per kilo. While it is somewhat more expensive than gasoline, the difference can be made up with subsidies and gas taxes respectively. Since in many parts of the world gasoline is already subsidized I'm not really seeing how this would be different from normal. Besides, many parts of Europe already have high enough gas prices to make this competitive without subsidies.

I think the question is whether it is a Primary source like oil, coal, wood, etc or simply a carrier.

Outcast you conveniently ignored the two other requirements. I said nothing else is as energy dense that is ALSO as practical and easily transportable as oil. Oh, and I forgot one additional requirement: abundance. Nothing else is as energy dense, practical, easily transportable AND as abundant as oil.

Incidentally, most of the items on your 'list' that have a higher energy density are refined from oil, so of course they will have a greater energy density. That's the point of the refining.

$this->bbcode_second_pass_quote('Ludi', 'I')t takes energy to make stuff.

Yes it does. Consider nuclear. A 1 kg Uranium 235 fuel pellet can give as much energy as 1500 tons of coal (source). That is a super dense energy source, but nuclear doesn't scale down very well, but we can still use that colossal amount of energy (at least some of it) for our vehicles by using it to make things like this. EROI doesn't matter as much with this amount of extra energy.
$this->bbcode_second_pass_quote('', 'a')bundant as oil.

It doesn't have to be as abundant as oil, because unlike oil the left overs from its use are intended to be re-used and recycled.
$this->bbcode_second_pass_quote('', 'a')s practical

Lithium borohydride was researched as a rocket fuel, so while it would require a new kind of ICE, it is not so far fetched. Direct borohydride fuel cells don't need platinum, although there is still some research left to be done.
$this->bbcode_second_pass_quote('', 'e')asily transportable

Lithium and sodium borohydrides are both solids at room temperature, unlike pure hydrogen so they don't have the storage problems hydrogen does.

And therein lies the problem. By the time one factors in ALL the energy inputs involved in this process (including those involved in the production of the various reagents):
Schematics (large)

I seriously doubt it gets anywhere near the equivalent, much less greater than the return of pumping a barrel of crude out of the ground...

All of which get recycled and reused, making it a one time expenditure. Plus the vast majority of this just appears to be reacting chemicals and moving them around.
$this->bbcode_second_pass_quote('', 't')he return of pumping a barrel of crude out of the ground...

There's more to it then that. After you pump it you still have to refine it, and then you have to make all the additives for it.

Since lithium borohydride is man made, there will be some energy loss, but nowhere near as much as a pure hydrogen system. Plus the electricity for the separators and the electrolysis can came from nuclear, which is so much more energy dense than any fossil fuel it more than makes up for any losses in the system.

Look at the date on that patent. 1977.

There are many reasons why these exotic alternatives don't get off the ground.

Chief among them is scaleability. They may work fine in the lab or for small-scale applications or demonstration projects. But they can't in any practical or economic sense replace the fossil-fuel infrastructure. The fossil-fuel infrastructure is there because it IS practical, or has been, at least. In relative terms, it has been virtually free, in fact. Now there's this notion that we can conjure up something in the lab to smoothly replace it. We can't, and all things show it.

Until a vision of alternatives is coupled with a vision of power-down, environmental repair, and reduced human population, I can't take this stuff seriously.
