The green man is a fake

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

As it has already been said "The amount of sunlight hitting the area of human skin is not enough energty to allow homeothermy and movement". What that means is that it is physically impossible to harvest enough energy from the sun for a body with such a mass/surface area ratio to support him to such an extent. Artificial algae won't change that. Alo, I seem to remember that the Green Man is not supposed to eat, etc. It's almost as if Wolfe forgot that photosynthesis is a source of energy but photosynthetic organisms still need "food" for structural building (growth) in the form of other nutrients.
