Using huge amount of rocket fuel to escape gravity is inefficient. Not a viable option for interplanetary travel.

Ion thruster is much more efficient. The key is to design a thrust amplifier or mix along with small amount of fuel. Dual engine type.

Using small amount of fuel and along with ion thruster engine to produce enough thrust to escape gravity.

No traditional rocket!!  That's not the way for interplanetary travel.

Traditionally engineers have to  burn 500 KG fuel to send mere one KG object into space from the ground! It is really a huge expense on energy for out-space program!
Now I wonder if your ion-thruster technology is workable and is not harmful for the environment?
Childish pure  mindset can simplify your life which let you live in a light way! Without man-made troubles you will work in high efficiency!

They do...

   China has strongest fibre that can haul 160 elephants – and a space elevator?

Scientists say just 1 cubic centimetre of the carbon nanotube material won’t break under the weight of more than 800 tonnes

Tsinghua University researchers are trying to get the fibre into mass production for use in military or other areas...
    Those cables would need to have tensile strength – to withstand stretching of no less than 7 gigapascals, according to Nasa. In fact, the US space agency launched a global competition in 2005 to develop such a material, with a US$2 million prize attached. No one claimed the prize.

Now, the Tsinghua team, led by Wei Fei, a professor with the Department of Chemical Engineering, says their latest carbon nanotube fibre has tensile strength of 80 gigapascals...
