underwater for energy?

I know I am new to the forum, but please bear with me as I try to explain some theories I have regarding a few things. I promise the post may seem like rambling at first, but in the end it will make sense to you.

As a child, I saw an experiment on some show (Mr. Wizard possibly) where an empty, thick, glass coke bottle was recapped and placed ten feet from a firecracker. The firecracker was lit, ignited and as usual nothing major happened except for the firecracker going off. Then, the same experiment was conducted at about 20 or so feet underwater. This time when the firecracker went off, the pressure created underwater shattered the coke bottle. This experiment has stuck in my mind ever since leaving me to fantasize over the possibilities of how much energy we can create underwater.

Several years later I took the same knowledge of the coke bottle experiment and began to think about the Philadelphia Experiment. There are supposed quotes that during the Philadelphia Experiment the amount of energy they created was rather a shock. I theorize that the energy created was magnified from under the ship into the water of the harbor and sort of bounced back off of the harbor floor possibly. That created energy would have magnified greatly into the water. Am I wrong in thinking this?

Also, I start to think of several other improbabilities that we keep coming up with per lightspeed travel. Underwater, I think we can create the energy we need to produce such power since every power generated there is magnafied so much....and by being underwater at such great depths with the pressure involved down there - we may have the way to contain our molecules at such a high speed ( so our molecules wouldn't seperate as is a common fear of lightspeed travel ). Does this make any sense to others as well?

I am probably not the first to think of these things, but I don't read as much as I should....so I hope I am not ignorantly rehashing old information. If so, just give me a good list of books to read up on. Thanks.
 
Willy,

The experiment that you refered to describes how a depth charge works as opposed to a similar explosion in the air.

The water doesn't magnify the force in the sense that I think that you're trying to state.

What happens is that under water the explosion accelerates and condenses a large volume of water where an air burst accelerates and condenses a large volume of air.

At STP (standard temperature and pressure) water has a density of 1gm/cm^3 and air is .0013 g/cm^3. Water is ~775 more dense than air. And that is at STP. It's much more massive than that when it is compressed by an explosion. Just how much more depends on the size of the charge and the burn rate of the explosive, the depth (ambient water density), temperature...

In Mr. Wizard's experiment the shock wave of the explosion didn't compress the air enough to collapse the bottle. The same shock wave under water compressed and accelerated the water with sufficient force so that when it struck the bottle it collapsed (or the submarine suffered a catastrophic hull failure
).

Remember that if all else is equal in the two explosions the general formula for the kineticenergy is:

KE = 1/2mv^2

The kinetic energy striking the bottle in the under water explosion will be on the order of 775 times greater than in the air explosion.
 
I fear the energy part is rather sci-fi in probability, but how do you guys feel about the ability to hold steady molecular structures underwater with such high compression? I just thought at least there would finally be a place on Earth to do such an experiment.
