Right, But as far as I am aware, nobody has requested state or federal  funding to build a space elevator in Minnesota as has been the case recently with PRT. Just this week, a PRT promoter asked the Hennepin County Railroad Authority for a resolution in support of PRT. You can watch the video of his presentation on my blog. Do you think the Wikipedia PRT article is a good source of information about PRT  for public officials faced with a decision to commit public funding or rights of way for PRT?
