A Look At Intel ISEF 2004 69
crl620 writes "Just this past Friday marked the end of the 2004 Intel International Science and Engineering Fair (Intel ISEF). This year's ISEF took place in Portland, Oregon with more than 1,200 participants. Over $3 million was given out and three grand winners left with $50,000. Winning projects include a homemade Scanning Tunneling Microscope (STM) and a brain-computer interface for the muscularly disabled. My picture diary of this huge event can be found here."

I'm not completely up to speed on airship technology, but my understanding is that this presents two problems:
1. To compress the helium, you need a stronger gasbag structure. Making the gasbag stronger makes it heavier, thus defeating the purpose of compressing it.
2. Compressing the gas simply adds more gas for the same amount of displacement. Thus you've actually made the blimp or rigid airship heavier instead of lighter.
Keep in mind that airships work by displacing air like boats displace water. The only reason that helium helps generate lift is that it adds structural integrity to the airframe/gasbag while being lighter than if it had been filled with air. The absolute BEST airframe is a complete vacuum. However, an absolute vacuum would require much stronger materials (1-1.5 atmospheres of pressure on the materials vs. a pressure of

It is all about floating the blimp, the bouyancy of the envelope. The difference in density is what gives you lift in a blimp (or a boat).
I assume you are kidding, you never know. I ran into a cashier at KFC that did't know how many were in a dozen, she insisted it was 6 in a dozen...

Even more efficient than helium, a really light particle, is a total vacuum which has no particles. To make an efficient lifting device, you can figure out the amount of total vacuum you would need to lift 250kg. Essentially, you would need the equivalent amount as the displacement of 250kg of air. For sake of argument, let's say this is 250 cubic meters. The beauty of this is that a vacuum, having no particles, compresses down to nothing. In fact, you could compress 250 cubic meters of vacuum down to nothing and store it inside the object you are trying to lift!
This amazing technology was used by the Egyptians in building the pyramids and by whomever built Stonehenge. The object itself thus becomes its own lifting mechanism. Ever wonder why modern man has been unable to reproduce such engineering feats? They've been unable to harvest the power of compressible vacuums to move great masses. However, I have shared this new secret technology with you in the hopes that you too will build marvels of the Earth.
The trick, of course, is not to store too much compressed vacuum inside an object or it'll just float away forever. King Tut was really pissed when the engineers first made that mistake!

I think this is where the aliens come into the picture. A strong, flexible tube running from Egypt into orbit would allow them to suck the air out of anything.

A brain-computer interface for the muscularly disabled, this can only lead to bad bad things in the long term, especially with Intel owning the technology. At first it will allow disabled people to do stuff, then when disabled people are forced to contribute to society more they will be programmed to do more...
