下面是Cavallaro给我的挑战书：

It seems that you alone have figured out that our DDWFTTW vehicle would violate the laws of thermodynamics.  So I have a spectacular offer for you.  I offer you the same wager that Derek gave Dr. Kusenko...  $10K.  So if you'd like to make $10K the easy way, and show me to be the charlatan that I obviously am, let me know.  Otherwise I'll assume you are like all the other many deniers - all talk.

Regards.

Rick Cavallaro
