The weight is still there going down... That should read ( 20 lbs - weight ) going down. Does the large diameter not give you any pause?

I am toying with an idea and not sure if it's feasible. Here is the setup: There is a 6' diameter steel pipe that is 30' long standing up vertically. Inside, among other stuff, are ~20 small 'trolleys' on tracks that run from top to bottom, spread out evenly among the cross sectional area of...

Agreed. And we didn't stop Hitler with a sit in... But I'm not arguing that some people (such as the Taliban) need to be killed. My original point was that when you design a weapon, you hand it over to some 18 year old soldier, and he is told who to point it at by some politician in...

Same as what Danger said, I happen to agree with you too, even though the worlds only super power is currently locked in 2 wars... And our most high tech weapons aren't helping us defeat guerrillas.

Oh yes, I've done that experiment before. I won't argue against boiling and condensing water as a powerful way to extract energy because that is the most prolific thermodynamic cycle we use for power generation, meaning the Rankine Cycle. But this patent seems to be about dissolving gas (he...

haha fair enough, but I've been reading into energy density of transport fuel a lot lately and this seems to me at first glance like it wouldn't be efficient. I've never seen the coke can experiment, can you explain it in better detail?

Summary of the patent: A piston cylinder setup containing a liquid and a gas with a strong affinity to absorb into the liquid. The gas wants to absorb so much that it will reduce the pressure in the cylinder, causing the piston to contract reducing the volume and producing force on the piston...

I can only explain it when she moves her body to the center that it will increase, but when she moves her body back to where she started you should be going the same speed. This is due to the conservation of angular momentum, like when a figure skater is spinning like a top and they open their...

Thanks for the reply, you helped me find an error in my spreadsheet! That is around the temperature I'm trying to reach, and I can keep getting colder by reducing the turbine inlet temperature in a counter current heat exchanger. Are you using this equation: T2 = T1 * (P2/P1) ^ ((k-1)/k) It...

Check out the attached image. My assumption is that if you can lengthen the piece I have shown, it will allow for a little more clearance and remain rigid.

I'm going to take a different angle on this thread... When I was a freshman in Mechanical Engineering I wanted to design weapons systems as well. Then I started watching all the unedited video leaking out of Iraq and I changed my mind really quickly. Have you seen what a 30 caliber bullet...

Hey guys, I'm trying to do some experiments at low temperatures in my garage. I have an air compressor that can push 6 cfm at 150 psi, and I want to expand this gas through an isentropic expander (NOT an isenthalpic expansion valve). Isentropic expansion extracts work from the fluid as it...
