So carbon nanotubes are incredible. Is a macrtube a possibility? If we stretched one out for centuries, and landed it on another planet, would it transfer gravity?
It's such an attractive idea but it would demand a lot from our technology and is probably just not feasible. The orbit of any object on the end of the elevator would beed to have a 24hour period or the 'rope' would wrap itself around the Earth. The end would have to be at the same altitude as Geosynchronous (TV etc. ) satellites. It's well worth Googling "Space Elevator" to find a lot of enthusiastic links which are usually not based too firmly on Engineering principles. Good fun tho'.Ibix said:You can build a space elevator in principle,
Launching into space without fuel is not possible with our current technology. Fuel is necessary to create the thrust needed to propel a spacecraft into orbit and beyond. However, there are ongoing research and development efforts to find alternative methods of propulsion that may require less or no fuel.
Some potential alternative methods of propulsion for space travel include solar sails, nuclear propulsion, and ion propulsion. These methods use different forms of energy, such as solar radiation or nuclear reactions, to create thrust and propel a spacecraft through space.
Finding alternative methods of propulsion for space travel is important for several reasons. First, it can reduce the cost of space missions by using less expensive or more abundant resources for propulsion. Second, it can reduce the environmental impact of space travel by using cleaner and more sustainable sources of energy. Finally, it can potentially increase the speed and efficiency of space travel, allowing us to explore deeper into space.
Yes, there are significant risks and challenges associated with launching into space without fuel. One of the main challenges is finding a reliable and efficient alternative method of propulsion that can generate enough thrust to overcome Earth's gravity and reach the desired destination. There are also safety concerns and potential technical difficulties that need to be addressed before any alternative method of propulsion can be used for space travel.
It is difficult to predict when we will be able to launch into space without fuel, as it depends on the progress of research and development in this field. However, some experts believe that we may see the first successful test of an alternative method of propulsion for space travel within the next decade, and it may become a viable option for space missions in the next 20-30 years.
