I would add: Khosla, who pushed green tech as a VC and with his private money.

ratan TATA , who pushed the low cost indian car , which is a sort of science fiction in his culture.

Idan ofer , who invested in "better place" the electric car company with the swappable batteries.

And BTW , i'm sure bezos see full e-commerce(including groceries and fashio and furniture) as a science fiction.
