what we jessica say? she would say time,, tom. remember that cell phone use opening. it gave me a whole new set of functions i never had before. it was great. you spoke in this auditorium twice. you know we already have lights. [laughter] and we don t really care whether the photons and electrons come from. so unless the mayor of d.c. comes along and says, from now on you re going to be the fully burdened cost of those lights, your to pay this u2 in napster, the cost of the troops protecting the oil in the gulf, they will now cost you $200 a like. what happens then? jessica gets on her cell phone which now costs only $25 says tom, your solar lights, and i ll take 10. and then what? then i m heading down the cost volume curve on my solar lights. sure, there is a transition but remember, as you go through this transition, your higher unit cost of energy will be higher, but you will be using less energy so he your actual bill, okay, system works as a wood and other technologies,
