I fly model jets that utilize miniature gas turbine engines. If one wishes to introduce a smoke system, A smoke oil tank is installed on board, The smoke oil fluid is then pumped from the tank to a spray nozzle located at the exhaust outlet of the turbine (thrust nozzle). The smoke oil is then...

I have been told that to solder properly the source of heat is to be directed at the bottom of object to be soldered (6 o'clock), Particularly, During a soldering operation to join two copper pipes.When I asked why that is, I was told it was due to convection distributing the heat around the...

How difficult/dangerous is this to utilize? I don't understand enough about electrical engineering theory to have a conceptual understanding of powering such a system. How does one go about obtaining such a high voltage without producing a dangerous level of amperage? Such a device would...

Hey thanks for the info Bob. I am looking into maintaining a system of water vapor as well, thanks Don. I should have also mentioned, It is critical that the system operate at a pressure that is NOT dangerous should the reservoir fail. Lets say I decided to go with laser diodes as Don...

Hey thanks DLgoff, That's a great idea. My only thought would be the longevity of the environment, Once the container is sealed (with what ever gas/aerosol is to be used) it should not be opened for its expected life. I wonder if a fog of some sort as you said would be comprable to an...

Hey guys, I guess I should mention first that I am not a student I had something in mind I would like to try but have very little experience with electrical components. I also do not have the best knowledge base in electrical theory. Im trying to find a somewhat practical way to cause a...

Well energy must be conserved so I would imagine that the amount of work done to pressurize the system would change proportionally to the energy of the new system. If your air system has energy X at 60 psi then an argon system may have energy X+10 at 60 psi, However the work done to pressurize...

Hello guys! Would an object about 6 ft in length and about 180 lbs hitting the Earth at 99% of light speed destroy the Earth? If not, what would it do? Obviously assuming it did not disintegrate due to frictional forces first. Can this be solved by a simple energy transfer equation? Thanks!

Thank you!

Hello friends! Would a star (O-Type) with max output peaking in the UV range, which was subject to (at distance) redshift 8 end up in the IR spectrum when its light approached earth? Would this be taking into consideration the doppler effect? BTW, yes this is somewhat an extension of my...

A recent (dumb) question that came to mind. Perhaps I posted in the wrong place recently. Given the brightest known star. What is the maximum distance we would be able to see it given current technology. Is there a rule or something? Say the divergence of photons vs initial brightness...

:redface: How about taking for instance the hottest/brightest stable star? is there a formula? Or one which must be adhered to in order to observe it correctly?

oh, sorry guys. It was a "heard it through the grape vine deal". I also heard it was backed by Bell labs, however I couldn't find anything official upon my search attempt, just the occasional physics enthusiasts "dark suckers" reiteration page. Out of respect for everyone here I did not want to...

Given current technology, and applicable laws, what is the greatest distance at which we can see 1 star?

Without taking up too much time, I came across this ridiculous article (only pasted the first 2 paragraphs) which supposedly was discovered out of Bell laboratories. What is this nonsense?? "A few leading scientists have come up with a new theory that is sending shock waves through the world...
