Can an onboard power source be used, instead of external power?
Yes. Calculations show that High Voltage DC of less than 200 kV, at a pulsed on/off duty cycle of low frequency in an on-board power system weighing less than 400 grams including rechargeable batteries, can be a reality with the larger 5 and 6-footers, Beamships Variations III and V. A piezo-based miniature system with an air-core transformer is now being developed by a major electronics supplier specifically for this purpose. Applied Electrogravitics is currently developing a digital/proportional R/C on-board interface module for use with commercial/hobby radio/control transmitter/xceiver units.
