Wrong.

Resonance Research Corp. has a 60 kV Electrothrust lifter that is powered by 
a power pack (battery) that lifts itself and additional weight.  It is 
totally self-contained --- not tethered to the ground.  At present we are 
investigating marketing options for this device --- possible military 
applications.  We are also investigating the best "steering mechanisms" for 
our new flyer.

Electrostatic fields do not require high current only high voltage so a 
heavy transformer is not required.  Our transformer units weigh less than 8 
oz.
