I have an idea of something I'd like to create and patent. I need to find a very small motion sensor and a motor to accommodate the sensor(similar to that of soap dispenser). Where can I find a website with instructions on creating such a device or where can I purchase what I need.

A teacher says the following is true:

XY + ¯X ¯Y = 1

Do you agree or not, if yes then why?
I don't because:
Z + ¯Z = 1 BUT if Z=XY then ¯Z is not equal to ¯X¯Y
in fact ¯Z = ¯(XY) = ¯X + ¯Y

any other opinions?

I saw an article and a patent for a new and revolutionary solar panel last year, with promises that they will be on the market soon. Has anyone heard anything more about these solar panels?

I'm looking to buy a tri-fuel generator. The one I'm looking at not only produces 110V but also 12V for charging a bank of batteries. How does it do this? Does it have two alternators, one for each voltage? If I'm only using the generator to charge my 12V bank of batteries, is it not the most efficient option because it's also doing 110V at the same time?

Thanks!

It's liquid bromine pumped into a heat source, vaporized, and moved.............to do something.

Bromine properties:
Boiling point: 58.85C
Latent heat of vaporiztion: 193.83J/g
Specific heat capacity: 0.473J/g-C

Don't worry about the heat source. It's just a meteor that fell in my back yard.
