SPACE ELEVATOR – FUTURE OF SPACE TRAVEL
Ever wondered? Travelling to space with your family?Fantasies?Boarding an elevator that will take you to space.Well,It will be possible in near future.
A Japanese company had started the plans for a space elevator. Therefore,it would be the most expensive infrastructure ever built.
Engineers of Shizuoka University initially proposed the plans.
ADVANTAGES OF SPACE ELEVATOR
It cost 10000$ to transport a pound.On the other hand,Space elevatorr will reduce the cost to 100 folds.
Rockets are heavier increasing fuel consumption.In contrast,this tech is lighter so fuel consumption will be less.
Obayashi corporation announced that in 40 years the space elevator will function.Secondly,it will carry 30 passengers.It will reach the outerspace within 7.5 days.
There will be only 4 components Tether,Anchor,counterweight and climber.Tether acts like a rope and is a tensile structure.Anchor and counterweight will balance the rope.Anchor will be attached in earth.Counterweight in the space station.Climber is a car.
The astronauts can use this car for traveling up and down the tether.In conclusion, it would acts as a connector between space and earth, transporting directly to space station.
CHALLENGES FOR SPACE ELEVATOR
Main problem is tether.It should be light,affordable and more stable.But,no material like this was ever built.
Powering the elevator requires some renewable energy.Because a light weight elevator cannot carry fuel tanks with it.
If elevator fails,no backup plan is there.
Collection of material for building a tether covering a huge distance of 36000 kms.
Rocket debris in space can damage the tether.
Carbon nanotubes can serve to make the tether.In addition they are stronger and tough than diamonds!
Using rocket waste debris for the raw material.Experimental tests can take place in Moon.
So no worries, no dangers as there is no gravity.
