I read material about power grids that explained how 3-phase power at the power plant is eventually distributed as 7200-volt single-phase power, which is then stepped down to 240 volts right outside the houses that are served.

My question is how the single-phase power (which is 7200 V or 240 V to ground) becomes two 120 V-to-ground leads that are 180 degrees out of phase with each other in my electrical panel.

Thanks in advance for your explanation.

I have a video camera and monitor that I want to use in a car. They use AC adapters which each output 12 volts, but a different amount of amps. I use an inverter to convert the car's DC current to AC, in order to power these AC adapters. Since the car's DC is 12 volts, I'm wondering if it's possible to skip the inverter and the two adapters and wire the devices directly.

I don't know the amperage of the car's DC output, or if it matters at all. Is there a risk of damaging the equipment if the amperage is too high or too low?

I readed a Deutsche news about bionics applications in non-pump irrigation online in July, 2006.

In this news, it is mentioned that the current
technical non-pump water lifting height is 10 metres, and the example in natural reality is about 100 metres. I want to know if the major principle of non-pump water lifting is about the surface tension of water and capillary elevation? I am wondering what are the major obstacles for artificial technique to reach the natural one.

From the formula of capillary elevation, it seems that the water lifting height could reach about 1000 metres (order of magnitude) if the redius of the capillary was about 10 nanometres (order of magnitude). Am I right or wrong in using the formula to make such a theoretical estimation? Are there any limited conditions for using the formula, which may not allowe me to apply it in such a huge scale? May be that there is difficulty in practice to achieve the theoretical one?

Thanks for helps!

Could anybody briefly descibe the following functions of a burner and how they fit in with each other.
Venturi, venturi throat, Mixing tube, burner body.
They all seem very closely related.
Thanks

So, how do we do it? I was thinking I could stuff blankets or foam rubber around it's intake of air valve and this would over-heat it..
Is this possible, or is there a better way?
