There's No Hyperloop in HS2. [£80Bn update]

Elon Musk played the media perfectly, with coy comments about at high speed rail alternative to the proposed LA to San Francisco project, building the intrigue with hints before finally releasing a comprehensive looking 57 page PDF with design and root schematics, costings and explanations. He certainly succeeded in grabbing my attention, and I think everyone should take his proposals very serious, however amazing they may seem; i.e. "Don't be afraid to dream a little bigger, darling."

He makes his PayPal co-founder, Peter Theil (via Confinity), look like a bit of a looser (especially after those losses at Clarium Capital the other year). Musk stuck to creating companies engineering new solutions:

Musk: robot, alien or superhero?

• SpaceX in 2002, the first private company to supply the ISS, delivering a $1.6Bn spacecraft project on time and budget. 
• Tesla in 2003, which makes all electric, domestic use cars that accelerate faster than Ferraris, now expanding rapidly into commodity price ranges.
• And SolarCity in 2006 (technically founded by his cousin from Musk's idea) which is "the largest provider of solar power systems in the United States", with Musk as the largest shareholder he stands to be an *extremely* rich person from this investment alone, given how solar PV is set continue growing exponentially in efficiency and scale over the next couple decades.

I mean, who IS this guy?! A visitor from some technologically advanced, alien civilisation? Or our future? Or JUST genius of a Tony Stark level competence?

So when musk says he can send millions of people per year, safely down partially evacuated tubes at 700mph, solar PV powered, electric turbine trains, riding only cushions of air, for far less than the expected budget of the unimaginatively planned rolling route... you'd best believe him!!
