whats wrong with this site?
takes a 100 tries to get a page to open.
oh well back to something more entertaining,,

Attention
possibly you must ADD the ON resistance from FET TO the coil resistance !!?? (for your calculation!)

Also you can think about that On Resistance is "ohmic"
coil resitance have an "ohmic" DC part
AND an "alternative resistance"
that incresed wit the frequency.

(Best example  : Loudspeker 8 OHM.
Test them with Multimeter  (mutch loower !!)
The 8 Ohm is  for Audio AC Frequency ( 1Khz or higher , ist to find in
data-sheets)

You should shorten the duty cycle.

If the system works off radiant energy then you need short duration pulses.  You will also lessen your power requirements if you do this.

Also, why are you guys hitting these things with such high power?  The original unit only used a 9 Volt battery.  You just need to flick the coils with a fast spike from what I can see.

A very fast transistor and a very short duty cycle will lower your power.

try open ended control coils, this will show you the electrostatic effect and should eliminate the heating issue with the FET's.

Also you might want to think about a static magnetic field for the coils
