Psychological/Physiological Effects Questions

Can the tubes be transparent, so people can view outside when they travel?

You are not alone in your thought, others have expressed similar concerns prompting detailed research into the issue of fears.  What we
discovered is that there are some people who are so claustrophobic that they cannot get into an elevator, phone booth, or even an

If there is a nuclear accident, can the tube be used to simply vacuum up the mess?

ET3 will be safer than other modes for transporting hazardous waste.  ET3 offers several levels of containment, and is very secure and traceable.  In the case of nuke waste, ET3 will need permitting from several government agencies before transporting such materials.  We are not focused on promoting ET3 for this use, but in the future it may play a role. 

Will people feel claustrophobia?

Some people are unreasonably afraid of enclosed spaces. The amount of room per passenger exceeds that of airplanes and luxury automobiles. Reclined seating and "virtual window" displays allow the simulation of whatever environment the rider prefers; or TV, movies, video games, etc. may be displayed to provide distraction from negative thoughts.

How can people breathe?

Life-support apparatus is a well developed field. Space stations in orbit allow astronauts to breathe for several months, even though the capsule is in a near vacuum. Submarines have been around for over a hundred years, modern subs can stay submerged for more than a month. The systems used in Evacuated Tube Transport will be much less demanding. Only 2-3 hours (plus reserves) of life-support is needed.

Can people handle the forces of going that fast?

Just going fast does not affect the human body. Astronauts in orbit travel faster than 20,000 MPH. The human body can tolerate 8g of acceleration or more for short periods of time. Top fuel dragsters are capable of about 4g acceleration. Many roller coasters produce 3g of acceleration. Most cars produce almost 1g under maximum braking. If acceleration is limited to 1g, most people will not experience any discomfort. The time to travel estimates assume a maximum of 1g of force, and a top speed of 4,000 MPH
