This is a C1166 Pulse Tetrode made by English Electric, who also made transistors. Good for switching 17 500 volts at 15 amps. But only for 1 microsecond every 1 millisecond (1T4 and AA battery for scale).
The filament alone needs almost 60 watts (9 amps at 6.3 volts).
Quite useless unless one wants to build a glowbug radar or something. But quite marvelous in a way.
Back in 1935, Charles Garrett built a carburetor that allowed a standard car engine to run on water.
The patents were immediately bought by the fuel companies and put on the shelf next to the Pogue carburetor and the Oglemobile.
I wonder what they’re going to do about these fellows making fuel from water using solar power?
Would you like an ad-blocker with that? Speak to Stefan. He's a cool guy.
