how do you breathe if the tube is a vacuum?
I know, on board air supply.
But, how do you allow for different people loads and different lengths of time to travel longer distances?
Answer>> this is all disclosed in the patent -- please consider that submarines stay underwater for months at a time, as do people orbiting in space -- all is highly proven, light weight, low cost, and very reliable.
What happens if the system has a failure (things DO break) and people are stuck inside?
Answer>> I believe your concern is safety, is it not? please realize that most freeway and air fatalities are NOT caused by failures, but by human error, weather, obstacles in the path of travel, etc. these normally accepted risks are all substantially eliminated by design in ETT. Also, ETT capsules have no moving parts (less than 1/1000th of the complexity of jet aircraft), and are by nature failsafe. Unlike aircraft, ETT capsules always operate in a highly controlled environment. It should be clear to anyone who closely examines the relative risks that ETT is many times less likely to fail than are cars or aircraft. Also, this is covered in more detail in the ETT patent.
How do you move a disabled car that is stuck in the tube?
Answer>> If failure occurs (remember that failure will be much rarer with ETT), where would you rather be: 7 miles above the ground (as in an aircraft)? OR,
On the ground, 3 inches away from rescue teams with equipment to effect reasonably fast rescue ?
The patent document discloses several ways to effect rescue and or self rescue; yet I doubt they will be used often enough to justify the added cost, and/or added risks of failure points.
So many basic things that are not addressed in your information.
Answer>> Please understand the Pickens Plan is NOT my website -- There is much more info on the referenced website
( www.et3.com ) - including the ETT patent document and images (good to open both in seperate windows when reading the patent).
AND, The et3.com website is only the "tip of the iceburg" of information we have accumulated on ETT design and implementation.
Thank you for your questions, and interest in ETT. If you have more questions after reading the patent, i will be happy to answer them as i am able to do so.
TRANSPORTATION is the master key to basic survival, and the cornerstone of the economy. We all know that transportation presently depends on oil production, and oil production is peaking. We must focus first on transportation – it is the highest priority. The PickensPlan to transition vehicles to natural gas is a great start toward 100% energy independence, but is a stop-gap measure till we can transition to all electric transportation. Electric energy is strained without adding transportation demands; so we must implement drastic efficiency improvement.
Evacuated Tube Transport (ETT) is a patented technology where travel occurs without air friction or rolling resistance (like “Space Travel on Earth”); ETT can accomplish 50 times more transportation per kWh (or carbon credit) than electric cars or trains. ETT is silent, low cost, safe, faster than jets, and is electric so it can make maximum use of wind or PV power. I invite you to visit my page to learn more about ETT
