How can one hit the $60B mark in five years? (Score 1)

A number of posts have suggested that it is potentially some form of transportation system which reduces pollution and traffic - based on various theories as to how the technology works. If you accept the premise that this product will hit the $60B threshold within 5 years then there has to be limited or non-existent barriers to its adoption or perhaps significant cost savings if implemented. My rationale behind this is that the sheer investment in dollars and the time necessary to develop the infrastructure for a new transportation project is tremendous - it might require well in excess of 5 years to complete the projects and deploy it. Consider the steps involved: gather the parties mentioned, i.e., city, state, universities, etc., approve a proposal submitted by this group, award the development contracts and implement the contracts - which presumably require infrastructure development, read construction and then full commerical deployment. Therefore, I am proposing it has to be something which completely leapfrogs the current infrastructure or leverages off of it with minimial modification. Otherwise, (i) the VC's would not embrace it so wholeheartedly after seeing the issues with adoption of other new technologies (read: Internet) and (ii) it could never scale up so quickly. I think it argues for something much simpler to install - such as a clean energy output device - perhaps fuel cells running off of the existing energy distribution system (natural gas or retrofitting natural gas delivery system for new fuel) for the home which produces H20 as its end product - kills two birds with one stone and totally wipes out or supports existing complicated and expensive ecnomic structures, i.e. power generation and delivery and water treatment and delivery. Alternatively, if it is a transportation device it must not require the infrastructures alluded to in some other posts. Either way, interesting stuff. Let's hope this is not "cold fusion" revisited.
