EmDrive engine and Sir Issac’s third law blues

#EmDrive Skinny:

  • Thrust is the reaction to an electromagnetic frequency (read vibration) and a waveguide (read metal pipe)
  • NO fuel (chemical, nuclear) required
  • The Universe is the “fuel.”
  • Newton is listening

Hotel Mars is a robust recurring John Batchelor Show segment with Dr. David Livingston,  AKA Dr. Space of The SpaceShow which reviewed #EmDrive propulsion with Dr. Mike McCulloch last week.

NASA’s thumbs-up that there is a there-there for #EmDrive has lit many Twitter feeds. Dr. McCulloch’s Twitter page  illustrates that the only constant of science is transition, not stability.

Note, Dr. McCulloch also presents an alternative to Dark Matter which he argues must be tweaked for each galaxy to explain the missing stuff which totals a galaxy. He calls his theory “quantised inertia or MiHsC” and his @worldscientific published  book, Physics from the Edge : A New Cosmological Model for Inertia to illustrate Dark Matter’s flawed data fixing to meet an observation.

Dr. McCulloch’s “notes” preparing for his #EmDrive propulsion Hotel Mars segment on The John Batchelor radio show with Dr. David Livingston had my mind spinning, thinking of terrestrial applications for #EmDrive besides traveling to Mars in 70 days.

If autonomous land vehicles are in their early days than #EmDrive land vehicles are not yet in their first seconds to continue the metaphor.

Second generation” land based #EmDrive engine conjecture from the U.K. company Satellite Propulsion Research Ltd (SPR Ltd) noted, “… 1 kilowatt (typical of the power in a microwave oven) of a static thrust of 3 tonnes (3,000 kilograms) can be obtained, which is enough to support a large car…”

But Newton’s law of conservation of energy (read energy cannot be created or destroyed, only transformed in a separated enclosed system, i.e. a land vehicle) dictates that an #EmDrive engine would need another source of energy to move the vehicle across the ground.

How soon before someone switches from Chemical energy to EmDrive energy for space use? How soon after that do we find a hybrid of EmDrive with electric vehicles for instant thrust and longevity?

As Dr. McCulloch noted, “… zero to 60 mph in days” is AOK if you have the time to accelerate to a tenth of the speed of light to reach the exoplanet Proxima Centauri b in a human lifespan, but would be a tough way to get to the pub for a pint, chips, and a banger.

Fun and fascination #EmDrive Twitter feeds:
