A vactrain (or vacuum tube train) is a proposed, as-yet-unbuilt design for future high-speed railroad transportation. It is a maglev line run through evacuated (air-less) or partly evacuated tubes or tunnels. The lack of air resistance could permit vactrains to use little power and to move at extremely high speeds, up to 4000–5000 mph (6400–8000 km/h), or 5–6 times the speed of sound at sea level and standard conditions.Though the technology is currently being investigated for development of regional networks, advocates have suggested establishing vactrains for transcontinental routes to form a global network.

Theoretically, vactrain tunnels could be built deep enough to pass under oceans, thus permitting very rapid intercontinental travel. Vactrains could also use gravity to assist their acceleration. If such trains went as fast as predicted, the trip between London and New York would take less than an hour, effectively supplanting aircraft as the world's fastest mode of public transportation.

He is best known for co-founding SpaceX, Tesla Motors and X.com, which later became Paypal after acquiring the service. He is currently the CEO and Chief Designer of SpaceX, CEO and Product Architect of Tesla Motors and Chairman of SolarCity. While at those companies, Musk co-designed the first viable electric car of the modern era, the Tesla Roadster, a private successor to the Space Shuttle, Falcon 9/Dragon, and the world's largest Internet payment system, PayPal.

Elon Musk was born in Pretoria, South Africa, the son of a Canadian-American mother and a South African father. His maternal grandfather was from Minnesota, and had moved to Saskatchewan, where Musk's mother was born. His father is an engineer and his mother is an author, nutritionist and model, appearing on the cover of New York Magazine in 2011 and a Time Magazine supplement in 2010.

Musk bought his first computer at age 10 and taught himself how to program; by the age of 12 he sold his first commercial software for about $500, a space game called Blastar.
