for example, in vacuum chamber drying saturated steam is used rather than using superheated or unsaturated steam.

When there is a power outage solar powered street lights would be more senseable to have enabling us to still be able to see the street and eventually save money. And help prevent looting.

i can purchase a copper diode that claims to provide protection against emf where electricity enters the house. advertising says it neutralizes energies. is this likely to be a true claim? thanks.

This statement is taken from a wind energy site (http://www.reuk.co.uk/Wind-Turbine-Water-Heating.htm):

Direct Wind Turbine Water Heating
"It is not usually possible to connect a 12 Volt water heating element directly to the output from a wind turbine. The voltages generated by a 12 Volt wind turbine are typically far in excess of their nominal 12 Volt rating - values of over 50 Volts can often be recorded in heavy winds which would rapidly burn out the heating element..."


Some figures:

Wind alternator rating: 12 volts, 200 amps @ 6,500 rpm
Heating element rating: 5,000-6,500 watts (Incoloy material)

As the figures above show, the power output of the wind turbine is well within the operating parameters of the heating element. Since the heating element can withstand the power output of the alternator (assuming it runs at a constant 6,500 rpm), in practice, will it be OK to do so? If more than two heating elements are used, will that translate to better safety and reliability?

Tnx!

We're moving from surface mount tantalum capacitors to surface mount ceramic capacitors. How do I properly size a ceramic capacitor in terms of rated voltage? With bulk tantalums we always spec a cap with a voltage that is twice or three times the nominal voltage of the circuit. Is there a similar rule for ceramics?

Is there a particular name for the big switch that evil villan's usually use for turning big machines on? It's sort of like a big handle that you pull down to connect 2 metal sticky-out bits together to make a circuit. Any ideas?
