Shawyers new EMDrive

Shawyers new EMDrive

Postby Good Elf » Fri Aug 11, 2017 1:41 am

Roger Shawyer's new EM Drive Mk#3 appears to claim vastly improved thrust. A small demonstrator VTOL vehicle weighing 701 KG (see below) can be constructed which will reportedly achieve Low Earth Orbit (LEO) and return to land is now proposed. The Shawyer RM Drive Mark #1 was tested in space by the Chinese and in the Lab by NASA's Eagle Labs in the US and appears to work, though this is disputed by some sources. A plausible explanation of the principle is provided by Shawyer. Though the original device achievers very low thrusts, his Mark #2 version is claimed to be much more improved, however so far no results from the testing of this earlier vehicle have yet been reported publicly, but some claim the device is under development "somewhere" and if the claims are as supplied, these results would be "definitive".

This latest version is Mark #3 sports a newly designed end plate and even further claims are made for increased thrust. Ignoring on-board needs for power and cooling, to supply energy to the various drive circuits and to maintain cryogenic elements, all versions do not require any "propellant", and if so could technically accelerate away from the earth as long as power is able to be supplied. Nuclear reactors could supply power for decades if necessary for example the Voyager Missions are still underway and heading out beyond the solar systems powered by SNAP atomic batteries. All current rockets use up their propellant in a few minutes but Shawyer's Drive could provide substantial thrust for years on end, ultimately reaching very high relativistic velocities. The biggest problem would be radiation shielding, a one way mission to the nearest star system could take less than a decade including a deceleration phase, and with Quantum Entanglement Teleportation Communication, results could be learned immediately. But it will depend on a substantial source of power such as a small nuclear reactor of some kind. But because the demonstrator design required a large superconducting plate, will require substantial low temperature cooling and a fuel cell power pack for the drive, since no room temperature superconductors are presently known ( but are currently being actively sought or under intense investigation around the world) and current batteries would probably be too heavy and/or too inefficient for this application. Maybe such missions will need to wait for the availability of room temperature superconductors. I dunno?
