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

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

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

Power Supply• Input = 12DC

• Converts to 35kV

• Regulates current (AC)

• Variable Spark gap

Problems collecting data

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
