The fuel coming from? I think Colin has the idea! Use one of the WWII British steam radios that were used in the south-west Pacific. They were 'powered' by the camp fire. Am I correct in thinking that the sets intended to be 'crank powered' used mostly direct heated [battery] tubes and those fast heating direct power tubes that looked like a metal 6L6? One would think that the design would minimize the waste power, simply because of the limited output of the [human] power source. Neil S. |

Several thousand liters to burn, more than I'll be able to use before radiation poisoning will get the better of me. snip Hi, The thing about an EMP device is that it is meant to be detonated at a very high altitude, so there is no radiation poisoning on the ground. Since the device doesn't directly cause loss of human life, the attacked country has a quandry whether or not to launch a "mutual assured destruction" response. A lot of the large power plant a.c. generators would be knocked out, because they use "brushless exciters" for the rotor. The rotor is excited by a small separately controlled a.c. field, and uses large semiconductor diodes that spin along with it, to create the needed d.c. within the rotor windings. 73, Ed Knobloch |
