| Highlands of Scotland - Steam Train |
How would you like to be able to travel between Europe and the USA, under the sea but at super high speed?
Apart from the obvious benefit of getting to your destination really quickly, it is possibly a greener solution to the current modes of transport.
The video today looks at how this could become a reality! It's full of science vocabulary to help with those science listenings and readings in the TOEFL!It is not too difficult and is just a short one so it won't take too long!
Here is the link: Air resistance
Vocabulary
To hurtle - to go at a very high speed.
To do away with - to eliminate
Airless - without air
To shove - to push hard
To impede - to put obstacles in the way
Questions
What kind of technology holds the promise for a transatlantic train system?
How fast might these trains travel?
What problem needs to be solved?
What happens as you travel faster?
How much power would the trains use if they travel in a vacuum?
When was vacuum tube technology invented?
What was it used for?
How does it work and what happens to objects placed in the tube?
Where are engineers currently doing experiments on vacuum tube technology and Maglev trains?
Can you describe the experiments they are doing and what happens to the speed of the train when it is in a vacuum?
How long is the experimental tube and how long is the proposed transatlantic tunnel?
Does the narrator think the experimental tube can easily become reality?
As I was doing this I wondered about the G-forces on people in the train....wouldn't they have an effect? I am sure someone out there can answer that!
