We have no natural source of anti-matter in near earth proximity to use for fuel. Yes, we can produce antimatter in particle accelorators, but the energy required to produce it far outweighs the benefits. Nuclear fusion will come before anti-matter energy is used.

you're right - the cost of producing anti-matter is directly related to electricity costs. So a cheaper and more efficient source of energy must first be in place: and we have Nuclear energy!

The dog can not bark his head off because at the precise moment when his head is severed, there is no barking

It would be a dead headless dog

One more problem. The fuel sources for nuclear fission aren't renewable ... and the sources must be refined for use as nuclear power. Fusion, on the other hand, can be powered by salt water, something we have plenty of.

I believe the "4th of July" celebration is only something America celebrates, but elsewhere in the planet, we treat the 4th of July as any other day. YES, Iran has a 4th of July, but it isn't a significant date on their calendar, I suppose.

I would really like to know if the sin of sloth was named after the animal, or vice-versa.

Better yet, skip the Dan Brown... Everyone seems to forget that he writes fiction.

Me? I stick with ltsimring... I hear his works are just so much... meatier...

From a CERN Sportlight on Angels and Demons:

The truth about anti-matter:

Can we hope to use antimatter as a source of energy? Do you feel antimatter could power vehicles in the future, or would it just be used for major power sources?
There is no possibility to use antimatter as energy "source". Unlike solar energy, coal or oil, antimatter does not occur in nature: we have to make every particle at the expense of much more energy than it can give back during annihilation.

You might imagine antimatter as a possible temporary storage medium for energy, much like you store electricity in rechargeable batteries. The process of charging the battery is reversible with relatively small loss. Still, it takes more energy to charge the battery than what you get back out of it. For antimatter the loss factors are so enormous that it will never be practical.

If we could assemble all the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes.

I was hoping antimatter would be the future answer to our energy needs. It seems more research is needed for this to happen.
No, the true answer is that it will never happen simply because of the entropy problem. Creating antimatter out of energy via E=mc2 unfortunately always produces equal amounts of normal matter and antimatter. This is fundamentally built into the universe. For any given amount E of energy you will get m/2 grams of antimatter and m/2 grams of matter. Putting these two amounts back together and annihilating them gives back E. But the process is not without loss: today the loss is enormous, but even if we could make the process very efficient, we would still not have any net gain!

It is not a matter of "more research" or "more advanced technology" to find ways around these limitations. Antimatter is a fundamental state of matter. It could only become a source of energy if you happened to find a large amount of antimatter lying around somewhere (e.g. in a distant galaxy), in the same way we find oil and oxygen lying around on Earth. But as far as we can see (billions of light years), the universe is entirely made of normal matter and antimatter has to be painstakingly created.

This by the way shows that the symmetry between matter and antimatter as stated above does not hold at very high energies, such as shortly after the Big Bang, since otherwise there should be as much matter as antimatter in the Universe. These energies are higher than any that can be achieved on Earth at present; what future research might tell us is how this asymmetry came about, although it is extremely unlikely to lead to the possibility of using antimatter as an energy source.
