Nathan Myhrvold's Recipe for a Better Oven
Indulging the Chowhound and the dork in me.
My God! Myhrvold's cured insomnia.
Really? "You can also create pulses of heat with oven wall panels that quickly change their conductance. One way might be through the use of variable-emittance coatings, which NASA and others have been developing for 20 years; these change their transparency or reflectivity when a current is applied. Another method would use tiny shutters made out of microelectromechanical systems or electrostatically actuated flaps."
You can picture the onanistic one-hand typing that attended authorship.
