And a pet peeve of mine (not necessarily related to the subject): Take a university, that gets substantial state funding. Take a professor and a (graduate) student(s). Take a couple of thousand lab hours and research using the excellent facilities provided and the good name of the university (built on what ? - see below) and you have a new valuable, proven idea. Then, these nice people go to a patent office (perhaps the university's) and patent it, and then they get support to create a company that markets the idea (again with some starting funding from the university and/or venture capital arranged through it). I beg your pardon ?! Funding for the research will have been at least 40% state contributions towards education, not subsidizing a firm (which is illegal in many countries, f.ex. in the EC, under most circumstances). How come this is possible ? How come tax money can be used to create 'wealth' sold back to taxpayers, with income tax and VAT tagged on ? Isn't this double taxation ? The US once upon a time had a law where any research that was done while being sponsored by tax money had to be released under an open copyright or to the public domain. They reversed that sometime in the 1970s. One of the results was the closing of access of universities to Unix source code, which led to the development (explosion?) of free open source software 10 years later, in the 1990s. This is probably one of the very few examples where such a positive outcome was possible. What about the rest ? What do people think when they take up mortgages to put their kids through university and then read in the newspaper what dandy high-tech firms the university spawned by blowing some of the tuition fees and state aids on research that becomes privately held intellectual property, out of reach essentially forever to those who paid up ? And meanwhile, the same university would enjoy serious tax privileges and status nobody else can dream of. Huh ?! Now with the new energy crisis and other problems (like hurricanes etc), a lot of university-generated information is used to find solutions to serious problems. Most of that information predates the 'turnabout' that made it possible for universities to sell their tax funded research. Papers used to design wind turbines and solar collectors almost invariably bear 1960s and 1970s dates. Coincidence ? Is it a coincidence that a web search for more recent serious studies in the domain (and often in any domain) often lands web hits with the now well-known Google 'un-sponsored' links that allow no access to information without paying ?
