Today we have news for discussion:

Could the spacecraft and satellites of the future be launched into space without fuel? 

Scientists at the UK’s University of Plymouth say that it’s a distinct possibility. Fortunately, they will spend the next four years testing this idea, with the help of a $1.3 million grant from the United States Defense Advanced Research Project Agency (DARPA). 

The grant recipient is Dr. Mike McCullough, who first hypothesized that light can be converted into thrust in 2007. The gist of his idea is called quantized inertia (QI) and it lies in the difference in the intensity of Unruh radiation in space, known as the Unruh waves. According to the hypothesis, if a damper is placed above the object, it will be propelled upward. 

Do you think propulsion without fuel is possible? If so, how significant will the drop in cost be compared to fuel rockets?

How much do you think the transportation of say 100 Kilos of cargo would cost?

What's more, the new engine will need a source of electric energy — where do you think it will come from? Are solar panels the only option?

And do you think there will be some kind of an emergency reserve energy source?

Let's discuss in the comments below.

YOU KNOW THE WAY YOU CAN FORM A BUBBLE UNDERWATER AND IT LIFTS UP, TO THE SURFACE. 

THE PRINCIPLE IS OSUND HOWEVER THE HYDROGEN PARTICLES WITH LIFT ON THE LAND AND SPACE ARE TOO FEW ,HOWEVER THE PRINCIPLE IS SOUND. TO CREATE A VIOD IN A SMALL AREA ON EARTH AND GAIN LIFT INOT SPACE. HOWEVER IT IS DANGEROUS AND YOU WOULD NEED ALOT OF AREA, LIKE OUTBACK AUSTRLAIA . THE IDEA IS SIMPLE CREATE A VIOD WHIC HAS LIGHTER INSIDE THEN AND CREATE THE LIFT INOT SPACE THERE IS NOSYSTEN THAT WOULD BE BETTER AT THIS STAGE, I WOULD LOVE TO DO THIS I JST NEED A 60 KLMS RADUIS OR BUSHLAND THAT NO ONE CAN GET HURT AND THE GOVERNMENT TO GO HALVES WITH ME. IT SHOULD WORK, THE PRINCIPLE IS SOUND. THE MATERIAL COULD BE A MATERIAL ELEMENTAL CHEMICAL ,MAGNIETIC BREAK DOWN THAT THEN RESULTS IN A VOID A LIGHTER THEN , TOMAKE IT HAPPEN.

OR YOU OCULD USE A GROUP OF SUB ATOMICS LIKE GLUONS AND BUILD A DEVICE THAT CAN SEPERATE THEM CREATINGTHE LIFT INOT SPACE, BY SEPERATING THEM IT WOULD BNELIOKE THE BUBLE UNDER WATER CREATING A LIFT CAPACITY TO THE SURFACE BUT IN THIS CASE THE BUBBLE CREATED ON EARTH WOULD LIFT AN AMOUNT OF WEIGHT INTO SPACE.
