Hi Keith: I am afraid egos have entered this discussion. The reality I see from all of the objections is some folks would like to be physicists. I think being a good physicist requires extreme depth. The objections I have seen are valid to understand where the extra energy is coming from. Once this is understood, it is helpful to look at what energy is required as input and what we receive at the other end. I am grateful for this discussion, it has been useful to me to organize these procedures in my mind, and to be able to re-iterate them in an intelligible way. Beyond that I am only seeing a distortion of egos.
Farmers seem to have a handle on this, they know the sun is providing a certain amount of energy to help them grow corn. But they are smart enough to focus on what energy input is necessary from them. Perhaps this is why so many farmers just shake their head in disbelief when a physicist speaks Wes On Behalf Of Keith Addison Sent: Friday, January 12, 2007 4:39 AM Subject: Re: [Biofuel] Pendulum Wes Moore wrote: >Oh yes I read what you wrote.
