"Electromagnetic Systems" provides another welcome hint at Gravitic Drive propulsion systems development for spacecraft. UFOs for those educated by the media. Not since Analog Magazine promoted the Dean Drive as a true space drive in the 1960s has a written source given a tutorial and a history of development leading, in this case, to the B2 that is worthy of attention. By the way, Dean had the theory right and the methodology wrong, You need to accelerate the electrons, not the masses they are attached to, in order to attain sufficient thrust.
This book proposes the idea that gravitational engines have been in development since WWII based on theories raised in 1923 by Dr. Paul Biefeld at the California Institute for Advanced Studies.And others, such as T. Townsend. This line of development works on the theory that a high voltage across a capacitor causes gravitational changes around the capacitor. References are made to the efforts of numerous aerospace manufacturers in support of this development during the 1960s to 1990s. Material from secret Air Force files and patent applications are presented to support this contention and the B-2 bomber's auxiliary propulsion system is noted as having the precise nature to support this goal.
Hmmmm. Let's take this to a logical conclusion. Others have noted that the B-2 take-off and landing times require it to move at 5.5 times the speed of the B-52s over the same track to Diego Garcia. If the B-2s average velocity of about 2800 mph is correct and adjusting for subsonic exit and entry tracks a speed of 3500 mph in orbital trajectory would allow them to accomplish this while remaining subsonc bombers( speed of sound in a vacuum is undefined you know). Depending on internal supplies of oxygen, food and recycling capability, the one way trip to the moon and mars could be roughly 17 and 48 hours respectively, assuming constant acceleration..No wonder the space shuttle was scrapped. And how is our Moon and Mars colony doing I would like to ask?
Buy the book and you will be able to ask even more interesting questions.
