Speedoflight.eu presents the electromagnetic pulse motor or EPM. The
EPM can propel almost any kind of vehicle. For
instance it can be fitted in and propel a car, airplane or hovercraft.
But its most
revolutionary capability: It might be able to move a spaceship at the
speed of light.
Electromagnetic pulse motor
As the diagram below shows, it is a very simple device.
It consist of two electromagnets (1 + 2) which are fitted in one line.
Two solid-state switches (3 + 4) control one electromagnet each. The
control unit (5) manages the solid-state switches and monitors
temperature, power etc. The power source (6): batteries or fuel cells +
bio fuel generator.
How it works
Imagine a car equipped with an EPM. In order to move it in the
direction of the arrow, solid-state switch #3 switches on electromagnet
Next electromagnet #2 is switched on and off (up to 400,000 times per
second) by solid state switch #4, and because the like poles are facing
each other, electromagnet #2 will try to repel electromagnet #1 and by
doing so, move the car forward.
order for this to work, the magnetic field of electromagnet #2 probably
needs to be stronger than the magnetic field of electromagnet
Suppose the car moves forward 1 mm every time electromagnet #2 switches
on. If electromagnet #2 switches on 100,000 times per second, the car
will travel 100 meter in just 1 second.
This equals a speed of 360 km/h and acceleration of approximately 10 G.
The peak acceleration of an Apollo rocket during launch is
approximately 8 G!
An acceleration of 10 G is quite fast. Unfortunately, humans can endure
this kind of
acceleration only for a relatively short period. Many experts think
therefore that for travelling in space an acceleration 1 G or 9.8 m/s²
is more realistic.
It would allow the crew aboard the spacecraft to live under same
gravity conditions as on Earth and it also would save some
energy. The EPM would only have to switch on 10,000
times per second to achieve 1 G acceleration.
However, is 1 G not to slow for travelling in space? Not really, as
Stanton Friedman explains on his website
, it would take a
spacecraft travelling at 1G approximately one year to approach the
speed of light.
Einstein a partyboomer?
at the speed of light might be great fun but according to Einstein's
special theory of relativity, any object that has mass cannot
accelerate to the speed of light. This sometimes called the light
When an object is approaching the speed of light, the relativistic mass
of this object becomes so large that even using all the available
the universe will not be enough to accelerate this object to the speed
Unmanned test flight
all physicists accept the light barrier theory. Therefore, instead of
sending humans on a dangerous and very long trip, it is wiser to send
an unmanned spacecraft to find out whether or not the light barrier
the advantage of keeping humans out of harm’s way, unmanned space
travel is cheaper and since there are no humans aboard, the
spacecraft can travel at maximum speed
Speed of light
In the "How it works" section electromagnet #2 switched on
100,000 times per second and moves the car 1mm forward with every
pulse. The car
accelerated to 360 kmh in 1 second.
Since there is very little atmospheric and gravitational friction in
space, the EPM should be able to move the spacecraft 1 cm with every
pulse. Assuming off course the spacecraft has the same mass as the car,
and the electromagnetic pulse has the same power the one that propelled
the car 1 mm with every pulse.
In the car example the solid state switched on 100,000 times per
second, but a solid state switch is capable of switching on 400,000
times per second.
If the solid state switch turns electromagnet #2 on 400,000 times per
second and the spacecraft moves 1 cm forward with every electromagnetic
pulse, the spacecraft could accelerate to the speed of light in just
under 21 hours!
