What happens inside the microwave to make it work? Does it shake the particles or what?

I intend to control an underwater ROV via fiber optic cable. Is there a device that exists that can accept a single PWM input, convert it to speed control instructions, and output those as PWM to speed controls?

Also, I need a way to convert either instructions on a laptop or a joystick setup to PWM.

I'm trying to control an underwater ROV using a conventional radio setup, with the tiny hitch that one obviously cannot transmit radiowaves through water. I was thinking of converting the transmitter output to PWM, piping it down a fiber optic cable to a pulse reciever at the ROV end, reconverting it to FM, and then running it to the reciever.

Now for my problem: how do I convert FM to PWm and back again, in such a way that a conventional radio system won't foul up?

I have made a wind generator out of cheap, everyday materials.
Is it possible to make solar panels for generating electricity from everyday materials, perhaps something like a thermocouple with two different metals?

2. why is 0.8% C steel very strong but much less ductile?
3. why is cast iron brittle, but still very widely usd?
4. why is martensite brittle?
5. why does toughness increases with tempeing time and temperature?
6. is it better to use a slow cooled sample , rather than a quenched plus tempered one?

Wouldn't this give out limitless power? I know it is really hard to make antimatter, but if there were a way to annihilate it with matter causing energy to be dispersed, is there anyway to use this energy as a fuel source? I can't wait until the future

One quick point - this isn't a stupid question, I know that the main function of a water cooler is to provide cold water. However the water cooler where I work also provides boiling hot water for tea, etc. The hot water comes out of the machine as the same speed as the ice cold water; yet it's actually boiling (with visible steam coming off it). How does the mechanism inside the machine work, to provide this function so quickly and efficiently? I can't find anything useful related to this on Wikipedia - so any genuine answers would be very much appreciated; thanks in advance '_'

Hello All,

I run a Design Company, and as part of my expension, I am mortgaging to build an "Eco-Friendly" office. I have grants from the DTI and assistance from several groups to build a "green" building at a smaller cost than a traditional "bricks and mortar" construction.

We are looking at using Solar panels on the roof to reduce our electric and heating costs, and potentially tying it in with a small windfarm. My question is, does anyone know (on a conceptual basis) what equipment is needed to allow these two energy devices to work in harmony with mains supply?

Your thoughts & advice are appreciated
