Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. Throughout space there is energy. — Nikola Tesla, 1892
When Tesla invented the first wireless communication device, he also discovered a form of free energy radiating throughout the whole universe. He planned on displaying wireless electric power with his Wardenclyffe Tower until it was sabotaged by financier J.P. Morgan.
Tesla conceded that his World Power System project was “retarded by laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.”
Perhaps the the world is now prepared for this technology as small applications using Tesla’s discoveries are finally being revealed to the public.
In a 1900 magazine article, The Problem of Increasing Human Energy, Tesla discusses a machine that can gather heat from the ambient air and other forms of harvesting energy from the natural world.
Just a short 112 years later, in March of 2012, scientists in Hong Kong built a graphene battery that turns ambient heat into electric current. This technology was picked up by UCLA researchers who claimed this same discovery as their own, seen in the video below:
More interesting Tesla technology came out in 2013 when a German university student invented a device that harvests electromagnetic waves to charge a battery.
Two more significant achievements have also been recently announced. One was seemingly being rolled out to acclimate the public to this coming technology, while the other quieter story is one where similar technology is already being used to power space propulsion.
Researchers from Washington University unveiled a wireless communication device called Ambient Backscatter that requires no battery.
They describe their device as:
Ambient Backscatter transforms existing wireless signals into both a source of power and a communication medium. It enables two battery-free devices to communicate by backscattering existing wireless signals. Backscatter communication is orders of magnitude more power-efficient than traditional radio communication. Further, since it leverages the ambient RF signals that are already around us, it does not require a dedicated power infrastructure.
They included an informative video explaining the technology and its possible uses:
Now try to imagine this type of self-harnessing power technology used on a larger scale. It’s currently being tested on the International Space Station.
On August 12th, 2013, the University of Maryland announced their success in powering the propulsion of satellites and the space station with a renewable electromagnetic power source. The project, sponsored by DARPA and NASA, is called RINGS (Resonant Inductive Near-field Generation System).
Besides testing electromagnetic propulsion, they also intend to use RINGS to demonstrate wireless power transfer (WPT). “WPT may offer a means to wirelessly transfer power between spacecraft and in turn power a fleet of smaller vessels or satellites.”
According to their press release:
New electromagnetic propulsion technology being tested by the University of Maryland’s Space Power and Propulsion Laboratory (SPPL) on the International Space Station could revolutionize the capabilities of satellites and future spacecraft by reducing reliance on propellants and extending the lifecycle of satellites through the use of a renewable power source.
Because a finite propellant payload is often the limiting factor on the number of times a satellite can be moved or repositioned in space, a new propulsion method that uses a renewable, onboard electromagnetic power source and does not rely on propellants could exponentially extend a satellite’s useful life span and provide greater scientific return on investment.
Associate Professor of Aerospace Engineering Ray Sedwick and his research team have been developing technology that could enable electromagnetic formation flight (EMFF), which uses locally generated electromagnetic forces to position satellites or spacecraft without relying on propellants. Their research project is titled Resonant Inductive Near-field Generation System, or RINGS.
RINGS was sent to the International Space Station on August 3 as part of a payload launched on Japan’s HTV-4 Cargo Ship from the Tanegashima Space Center. The project is scheduled for four test sessions on the research station. Astronauts will unpack the equipment, integrate it into the test environment and run diagnostics. From there, RINGS will undergo three science research sessions where data will be collected and transmitted back to the ground for analysis.
RINGS is composed of two units, each of which contains a specially fabricated coil of aluminum wire that supports an oscillating current of up to 18 amps and is housed within a protective polycarbonate shell. Microcontrollers ensure that the currents oscillate either in-phase or out-of-phase to produce attracting, repelling and even shearing forces. While aluminum wire was chosen for its low density in this research prototype, eventual systems would employ superconducting wires to significantly increase range and performance.
In the spring of 2013, RINGS was tested for the first time in a microgravity environment on NASA’s reduced gravity aircraft. UMD graduate students Allison Porter and Dustin Alinger were on hand to oversee the testing. RINGS achieved the first and only successful demonstration of EMFF in full six degrees of freedom to date.
“While reduced gravity flights can only provide short, 15-20 second tests at a time, the cumulative test time over the four-day campaign provided extremely valuable data that will allow us to really get the most from the test sessions that we’ll have on the International Space Station,” said Sedwick.
In addition to EMFF, the RINGS project is also being used to test a second technology demonstrating wireless power transfer (WPT). WPT may offer a means to wirelessly transfer power between spacecraft and in turn power a fleet of smaller vessels or satellites. Having the power to support multiple satellites, and using EMFF as a propellant-less means to reposition those same satellites, provides the flexibility to perform formation control maneuvers such as on-orbit assembly or creating synthetic aperture arrays. A synthetic aperture array uses a network of smaller antennas to function collectively as one large antenna. Larger antennas are capable of producing higher resolution images and better quality data.
And these are just some of the recent examples of the unveiling of this technology which seemed to have been largely under wraps until now.
Is the age of free energy upon us? Will some of this technology escape and go open source?
