A Look At Intel ISEF 2004

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 made battery out of a lemon and some pennies, but i didn't get past the first round.

It's all in the presentatation. Think of the scientific mileage Pons & Fleischman could have milked out of that lemon.

Then I went to the Reed College Nuclear Reactor which was a neat open-pool reactor. We got to see the core and also see a SCRAM where they drive control rods into the core.

I hope he was wearing his metal cup shielding

Milk and lemon, think of all the cool curdling that would go on!

Actually, I recently considered what it would take to build a go kart for the sky. My idea was to take a basic frame (like that of a go-kart), add blimp-like "pontoons" to the sides, and attach a lightweight propeller to the back. I figured that if I could get it to lift a few hundred pounds, I'd have myself a new way of getting to work. The problem came in when I did the actual calculations.

To lift one kilogram of weight, I need about .4 kilograms of helium. This didn't sound so bad until I found out that the .4 kilograms of helium takes up about 1 cubic meter of space. I then assumed two gasbags, each one cylindrical, about one meter in diameter, and 4.9 meters in length. This worked out to about 8 cubic meters. (.5^2 * 3.14 * 4.9 * 2 = 7.693 m^3) 8 cubic meters would only give me 8 kilograms of lift! I then did the figures to lift 250kg of weight, and found that I'd need a gasbag the size of my living room to lift it.

Ah well, another idea bites the dust.

Did you consider compressing the helium? Compressed gasses take up less space, so you would have needed a much smaller envelope.

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 .01 atmospheres in a standard blimp). These stronger materials would of course be heavier and thus defeat any gains you would get by creating a vacuum.

It's a common mistake. People tend to have the idea in their heads that helium is a magic anti-gravity substance. Once you point out their error to them, they tend to realize that they'd never really considered how it worked in the first place.

In short, cut the guy some slack will ya?

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!

Some lame-o actually did this!! look at this kid's photo (second one down) of the project which he clearly marked "uncool" http://isef.syndetics.net/projects/. The person clearly didn't even understand simple oxidation/reduction potentials of metals. How dreadfully embarrassing when juxtaposed with >a href=http://isef.syndetics.net/projects/C%20-%20La st%20Years%20Winner.JPG>this.

Something is wrong with the site...

[gatzke]

I went to the site and opened 20-30 tabs to load the various images in the photo journal, but for some reason very few of the images have loaded. The ones that did load so far do look pretty nice, but boring...

OMG, They all loaded eventually. Amazing.

Strange coincidence?

[WoodstockJeff]

One of my clients called today asking me about home-brew STMs. There's a site that we found that covers where to find research papers on building them for around $2K...

Re:Brain-Computer interface?

[gandalphthegreen]

Don't the Borg use a brain-computer interface to network their people together to become one?

The Borg aren't real. Yes I know you know that, but I think it's worth pointing out to put the tin-foil-hat arguement in perspective.

Pictures of Airport Computers?

[bdigit]

That doesn't seem like a smart idea to be doing. A kid walking around photographing the terminals, the ticket reader and among other things. Post 9/11 I am surprised a security guard didn't tackle him to the ground and then have the FBI come in and question him for 9 hours. Sure he was just harmless ly taking photos but not a good idea to be taking photos of the equipment like that.

Browsing through the pics...

[Serk]

Browsing through the pics I had one thought that kept going through my head:

Cool! Someone even geekier than myself!!

But than cold reality crept back, and pointed out that, while the taker of those picture might be geekier than myself, he isn't MUCH geekier than me...

This is a great, exciting experience.

[Richard Mills]

I participated in two ISEF's (1994 and 1995) when I was in high school. I think that very few events I have participated in conveyed the excitement of doing science and participating in the scientific community like those ISEFs have. I'm just about finished with my Ph.D. now, and of course I've been to plenty of "real" scientific conferences, but none have captured the excitement that I experienced at those ISEF's.

If anyone involved in organizing the ISEF reads Slashdot, I hope they read this testimonial. Participating in ISEF was very important for me and many of the other students, and the experience really helped cement my decision to pursue a career in the sciences. Thanks!

Sometimes less can be more

[wombatmobile]

So many pictures, so few highlights, so little time.

Remember when photography took 24 hours and cost real money per click?

I, too, was at Intel ISEF 2004 and also went on the BPA tour! In fact, I think I know the kid who took these pics... Anyway, check out my gallery of the whole ISEF experience.

Hey I was just reading wired today and saw the new AI lab that Frank Gehry designed. So cool, and this picture of you and Rod Brooks brought back some memories for me too. In 1992 I was at the ISEF engineering project entitled Computer Controlled Robotic Crane. At one point during my life I ended up at MIT at the AI lab and always had a keen interest in listening to Brook's philosophy on robotics, so analogous to a biological model :) Its very cool that things like the ISEF are still going strong and that people are still interested in science and willing to pursue it, and it looks like you got to do some pretty cool things too. The one lament I have is that I've only kept in touch with a few people from the ISEF, though one is my best friend, so I can't complain to much, but there were so many talented people there that its a shame to have not taken in more of the people around me then.

ISEF is amazing, anyone that can do it should try

[Anonymous Coward]

I attented ISEF in 2002 and my team won grand prize for teams in 2003 at ISEF (BEACON) and we were awarded a free trip to europe to display our project at the EU science fair. (we coulden't compete, we are clearly not in the EU). This science compatition is an excellent way to get yourself on the map and get your foot in the door with many professors at many universities. It also is one of the best way to make friends and learn that most science nerds are not as nerdy as you think.

I loved the ISEF

[Cyclotron_Boy]

I participated in 93, 94 and 95. I actuall won Grand award in 94. Those were some of the most fun times I had growing up. The projects really did vary in quality and dedication, but overall the experience is usually wonderful for anyone that participates. I met a number of physicists, and actually got a job at Fermi National Accelerator Lab as a result of my projects and the interest they generated. I actually left my PhD program and now work in the real world, but the ISEF really did introduce me to science on the grand scale. I wouldn't have gone into physics if it hadn't been for the ISEF. I am also currently trying to get my company to sponsor special awards at the ISEF. I figure it is the least I can do to give back.
