Engineering - October 2007

I need to find a way of heating large volumes of rapidly moving air (wind) quickly, so as to create an artificial thermal that preceeds below an aerofoil wing for the generation of lift. What device can I use to heat the surrounding air effectively enough to create a thermal, that has no moving parts at all, and that can be interfaced with a solar panel??

A 12v DC power supply from a 500 Watt power supply unit is being used to heat a wire of approx 1 meter. As I understand if more current passes through the wire, the hotter it gets. In order to vary the heat of the wire I need to vary something.

My question is...

What is that something and which way is it to be varied (as in up or down)?

Also what would I need to do it ?

Many thanks,

Paul

I'm trying to visualize shock waves for gas flow in piping systems (choke flow); but all there seems to be out there is for external flow (aeronatics). Is there a picture of a shock wave on a PSV or orifice plate for choked flow, I'm having trouble visualizing pressure waves for pipe flow, its easy to see for aircraft but not for gas flow in piping systems (restriction orifices, PSV's etc.).

I'm a machinist and I need to make a precision reflective surface, I can put a mirror on it, but I'm not sure how accurate it would be. But I know I can machine and grind a surface with a mirror finish. Will this be comparable to a mirror though?

So i have picked between either of these majors and am going on to get an masters degree then MBA after college. my question is which can i get more involved with marketing/sales? my future goals are to make alot of money this way and start researching/working on anything space oriented stuff far as getting our race off the planet and to the moon and beyond. with electrical engineering i could explore new energy technoloies but with mechanical i could just as well design the spaceships themselves! can you see the predicament im in? i just cant decide which has the most practicality for the rest of my life according to my goals. far as position id like to be a ceo hence getting the MBA degree. (dont you hark on me you English majors, i know i there are some misspelled words ha). thanks -Nate
