I'm guessing you will flash plate everything within a 3 foot radius.

I think you could probably cook a turkey with that. My initial guess would be that the turkey could have a starting temperature of -273C (absolute zero) and still get cooked. Since I have extra time not being an officer of DPRG anymore, I attempted the calculations: Disclaimer: You might want to check my work if you decide to carry the experiment out with expectant dinner guests. Figuring latent heat of fusion to thaw the bird once it reaches 0C (334 kJ/kg) plus 4.2 kJ/kg per delta degree C. I calculate for final temp of 80C (176F) and above stated 1MF capacitor charged to 2.7 volts: Bird kg x (334+ (273+80) x 4.2) = 3600 kJ Bird kg = 3.81 kg = 8.4 lbs Not a very large turkey, but with a pre-thawed turkey at say 5C. The calculation yields a 25lb bird can be cooked. Maybe we can try this out at tomorrows RBNO at the generator. I will spring for the bird if someone will bring the capacitor(s).
