Days after the towers fell during the clean up, there were pockets of molten steel in the debri. You can find pics of heavy equipment picking up glowing red hot fused together steel here www.911physics.com along with many other interesting facts. Jet fuel can reach a maximun temp of 1800 degrees (not enough to melt steel). So where did this molten steel come from?? Is there any known materials in WTC 1 and 2 that would burn hot enough to melt steel in less than 2 hours?? A radio communication from a firefighter on the 78th floor said this:"Ladder 15, we've got two isolated pockets of fire. We should be able to knock it down with two lines. Radio that, 78th floor" you can listen to it here http://rapidshare.de/files/9140213/FireFighter.mp3.html This would have been very close to the impact zone. Hardly seems like the type of fire to melt steel does it?? How can the vast majority of Americans just ignore things like this??

I have built a turbo jet engine, I have a spinning shaft off the compressor side of the turbocharger. I need to send a light beam onto the shaft then because the shaft as 6 points I should be able to count the rpms that make and brake the light. what type of light beam? can I use a 555 timer that can be triggered by the light beam and then send it to a digital counter? I have used a 555 timer in my ignition system that pulses a coil to spark the spark plug, that ignites the propane. so how and what type of light beam with the 555 is the question. thanks for all input, dave

any ideas for this project would be greatly apreaciated.

We own a Titan II missile site. We have excavated the access portal (a shaft 20'x20'x50'deep) and have gained access to the cableway leading to the launch control center. This is a 3 story circular building 45' in diameter. The cableway (tunnel) connects to the control center at the middle floor (50' underground) and there are then stairs leading upstairs to the crew quarters or downstairs to the main chiller system for the site. The air in the control center (all three floors) is very stale even though it is a constant 72 degrees. I want to know how I might go about exchanging the stale air for fresh air so I might be able to start cleaning out the control center. I can get power to the site via an extension cord. I look forward to your assistance on this neat project. Thanks.

I am interested in building a fallout shelter using 40' x 8' cargo containers. How deep can I go using this before the weight of the earth is too heavy. The sheetmetal panelling is 14 gau. I believe that earth is 100 lbs. per square ft. or something close, although I haven't looked too closely.

I'm looking for a desktop version if you have any schematics/drawings/parts lists. I'm only looking for one that you have built and verified it works.

I was in a surplus shop with all kinds of inductors, coils, chokes, transformers, etc The variety of these devices is amazing.

How are these devices designed? How are they measured?
How do the turns/radius/core determine the inductance?

They are such basic devices, but I have never seen a standard multimeter capable of measuring it. Why?

Just curious how I would know how to measure and design them from scratch?

Thanks for any creative answers.
