Are infrared heaters effective and cost efficient?

No you are not confusing at all, however I think that trying to build one from scratch is a bit more then you care to take on. This is a big touch frame you are trying to build and would be incredibly difficult, having done this before it is recommended that you have one built for you, I have used Screen Solutions in the past. http://ssidisplays.com The USB cable from the touch screen is connected directly to the pc, the driver interacts with the pc and will communicate the touches.

Good luck with your project!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
