9. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Balloon Chase and Recovery Balloon flew 400 Miles across Texas, at 130,000 feet in the air.

10. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz n Normally you can't see, hear or smell electricity, but the Tesla Coil makes Bright sparks Bright sparks Loud crackling noise Loud crackling noise The air smell strange (Ozone) The air smell strange (Ozone) SAFETY FIRST! BRACE YOURSELF! 1 Million Volts! DANGER n Distance at least 20 ft. n Computers, Gameboys, CD players, telephones to the back of the room – unplugged, switched off! n Hearing aids off, pacemakers out of room!

11. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Three things to understand: n Electrical Current n Lightning n The Faraday Cage

12. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz ZorroZorro Drawing lightning with a sword

13. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Sparks to grounded sword What is happening with Zorro? Wire to safe ground What about those lights without cords? Electricity Moves Through the Air (you knew that, because you use a radio and TV

14. UC Santa Cruz Tesla at Freedom 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 very small bodies called “molecules”. When they are broken apart, 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 (like in your toaster!). Electricity in Air

Why aren’t they in grave danger from lightning? ++ + + + + +++ ++ + –– – – – – – –– – – – – + +++ + + + Safest place during a lightning storm is in a plane or car because it is a Faraday Cage Answer: They form a “Faraday Cage” -- that is, they are surrounded by metal. Electricity flows around the outside of the metal, and anything inside is safe!

18. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Thomas “DC” Edison Thomas “DC” Edison and his Batteries Nicola “AC” Tesla and his Generators vs. n Tesla Revival n 271 web sites are dedicated to Nicola Tesla n Join the “Tesla Coil Web Ring” http://nav.webring.yahoo.com/hub?ring=teslaring&list

19. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz n Nicola Tesla as a Daredevil waiting for a hair cut? n Double Exposure makes it safe!

20. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz The “Chicken Coop” The World’s Ugliest Faraday Cage -- and it’s full of holes! But can it keep the lightning out? Does the chicken trust the equations? equations?

21. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Voltage starts at 120 ends up at 1 million! Transformer 14,000 volt Outlet 120 volt Resonance circuit 1 million volt Ask us about details! How does the Tesla Coil work?

22. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Learn about Transformers Where have you seen this before? Power comes out at 14000 Volts Power goes in at 120 Volts

23. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz We heard a lot about conserving Power (turn off lamps, air conditioners, close refrigerators...) Power is brought to your neighborhood on high voltage lines on high voltage lines and a transformer brings it down to 120V We heard a lot about conserving Power (turn off lamps, air conditioners, close refrigerators...) Power is brought to your neighborhood on high voltage lines on high voltage lines and a transformer brings it down to 120V Physics Principle: Transformer Power goes in at 14000 Volts Power comes out At 120 Volts

24. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Transformation of Energy GLAST SLAC n Power is used everywhere –Visit the Stanford Linear Accelerator Center (SLAC): Electricity -> New particles Quarks Power is tranformed in Space Power is tranformed in Space Black holes explode : Black holes explode : – Material -> Light, x-rays, “jets” – SCIPP works on GLAST Mission: discover the most powerful “power plants” in the universe discover the most powerful “power plants” in the universe

25. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Learn about Resonance That’s how a swing works: A kick at the right moment builds up and gets you sky-high! That’s how a swing works: A kick at the right moment builds up and gets you sky-high! In the Tesla “swing”, the kick is supplied by the AC electrical current moving back and forth In the Tesla “swing”, the kick is supplied by the AC electrical current moving back and forth

26. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Mystery Knight Who is afraid of Lightning? Not the Mystery Knight! Not the Mystery Knight!

27. UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Electrical current flows on the OUTSIDE of a metal! Is Mr. Rasmussen OK?Let’s check! The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside Is Mr. Rasmussen OK?Let’s check! The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside Invisible current Visible sparks Ground 1 Million Volt Visible sparks
