-> Another cold fusion story? Is this a hoax? 
  
I wondered, too. But they're not claiming to produce "useful" amounts 
of energy.

-> There we have it: Eenrgy isn't expressed in Volts! 
  
But electric potential is. Maybe the "energy" was put in as a result of 
a bit of sloppy usage.

-> 25 V/m is not a strong field. Certainly not enough to strip electrons. 
 
-> Cheers, Michiel 
  
You didn't notice the "n". 25 volts per *nano* metre, or 25 GV/m.
