In the Chris Froome thread in the Pro Racing subforum, I saw a picture of Froome preparing for Rio 2016 in a "Peak Performance Chamber" by GlaxoSmithKline. In this chamber oxygen levels, humidity and temperature can be regulated. I also remember reading Team Sky's super performance on stage 10 of the TDF was explained away with the story that they had trained in a special chamber in which they mirrored the predicted conditions for that stage; this might have been the same chamber/machine. This made me think at the time and now that I see it again, I started wondering, do other teams have access to similar chambers? I remember reading a reply on the theguardian.com website, stating that Tinkoff-Saxo had tried to get their hands on the ketone drinks but you have to be besties with Oxford University to get them. I searched the comment section for that reply a while later but it appears it has been deleted just like all other replies questioning Team sky

anyway my question: does anyone know if other teams have access to such chambers? And if they don't surely we have to wonder if this is what we want: multi-million dollar teams owned by huge companies with massive influence and many connections in their country of origin, leading to a massive technological and scientific advantage for these teams? It's not even just a matter of larger budgets: I understand a team with a bigger budget will have an advantage. But if one team can use methods other teams can't, no matter how much money those other teams are willing to spend.....?
