UC Santa Cruz Tesla at Crittenden SCIPP UC Santa Cruz We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is converted wind, water, thermal power We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is converted wind, water, thermal power Physics Principle: Transformer Power goes in at Volts Power comes out At 120 Volts It is brought to your city on high voltage lines to transformers

UC Santa Cruz Tesla at Crittenden SCIPP UC Santa Cruz Transformation of Power The SLAC linear accelerator creates 90 Billion Volts, as much as 90,000 Tesla coils! We use that power to make new particles for scientific research

UC Santa Cruz Tesla at Crittenden SCIPP UC Santa Cruz Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle:Air is made of molecules. When they are ionized, they become charged and can conduct a current like an electrical wire. If there is a large current, it heats up the air and makes light. Thus, the sparks, flames etc are direct evidence for the model of atoms! Electricity in Air

UC Santa Cruz Tesla at Crittenden SCIPP UC Santa Cruz The Faraday Cage –– – – – – – –– – – – – Are you safe in an airplane or a car during a lightning storm? Is it safe for the knight to be hit by the lightning bolt? Yes! Electric current flows invisibly through the outside of the metal shell (Faraday Cage), not touching the people inside.
