Answer: Another good question.
Richard Nelson first used the technology for private experiments from the time of invention (about 1973) until about 1979-80 when the first patents were applied for. Then Nelson used the technology as a basis for his private R&D enterprise that was funded by private and government funding until about 1995. During this time many “commercial confidential” laboratory, field testing and demonstration scale projects were implemented, the largest being a 6,000 square foot greenhouse at McGill University in Montreal.
Since then, Richard has helped numerous inviduals and groups to build greenhouses using the SolaRoof technology. Along the process, he has encountered several attempts of taking ownership to his intellectural properties once the people involved see its huge potential for profits and real life applications.
The simplicity of this technology itself creates three problems for its wide use: (1) The general public thinks it is too good to be true; (2) The commerical operators think it is too simple to hide any business secrets inside its commericallized products; (3) The so-called experts either lack the insight to conceive its full capacity and potential or look down on it as such a low technology to warrant heavy research and study – the opposite is true which opens up a new area in science: Bubble Science.
Over the course of Richard’s persistent effort of promoting it, some have shown tremendous interests in SolaRoof but somehow still lack the persistency to push it to its final commercialization stage. One has to handle it with their own hands and use it to themselves in order to effectively convince others.
Well, there is one more reason that is common to all good things in life: there is a spiritual battle involved that the best thing is always the last to come. That is, a person has to battle with his or her own devil inside to put it into use.
