3. Overview A Lifter is an asymmetrical capacitor which uses High Voltage ( > 20KV ) to produce a thrust. Equivalent to a RC circuit. Lifters work without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus some additional load. Lifter is 3.7g and the distance between the wire and aluminum is 2.9cm Theories behind our lift –Ionic-Wind –Biefeld-Brown effect –Electrogravitics

4. Synopsis of Lifter Topics The initial goal was to study the reasons why our lifter was able to oppose gravity and lift with no moving parts. –Shape/surface area (stability) –Wire and foil distance (arcing) –Wire type (consistent plate separation) –Resistors load

5. Chapters of Lifter Project Damaged power supply –We think the polarity to the battery was inverted. –Provide more protection to the circuit/power supply. Preventing surges or wrong polarity. Collecting data and more efficient way to collect, with more accurate data. Any outstanding problems and suggestions for future improvements. Problems collecting accurate data… Spark gap adjusted fixed lift Blew on lifter, to finally get it to lift. After that it always lifted Lowered the load resistance from 10M ohms to 4M ohms Construction of the Lifter is very tedious. Having the right distance between connections so the lifter works properly. Efficiency on building new lifters

6. Power Supply Input = 12DC Converts to 35kV Regulates current (AC) Variable Spark gap

7. Problems collecting data

8. What we have done We have constructed multiple working lifters. Recently troubleshot and repaired our power supply. Collected data on our working lifters to compare and better understand their operation. Examined the effects of ionic wind
