New Approach to Space Based Solar Power from Satellites
Patent Pending
The great bulk of our energy comes from fossil fuels of which there is a finite supply and the use of which is having adverse effects on human and planetary well-being. Nonetheless, world demand for energy is growing rapidly. Since greater supplies from our present sources are made available only at increasing cost and, most often, with even greater environmental impact, we must seek new sources that will be sustainable, economical, and which will not exacerbate environmental damage.
A revolutionary new power technology is needed for man’s future cutting off the terrorist threats by countries or individuals to the world’s security. Microwave power transmission and space power satellites proposed for the future use a wide array of physics and science fiction in an attempt to achieve power from space and solve this problem. All attempts to date plan on converting solar power into laser and microwave energy transmitted to Earth which need a multi-billion dollar satellite parked in GEO orbit to work costing hundreds of millions in rocket launch cost. The launching of the $ 500 K (ea.) Microwave Power Transmission Satellite (MPTS) to a 200 – 350 mile LEO orbit would cost hundreds of thousands of dollars to a tens of million where hundreds of these low orbiting satellites would be launched. The efficiency of solar panel technology conversion of light to electricity with the best technology available today is 10 to 15 %.
In contrast, a microwave power transmission satellite ( MPTS) using electrons from the ionosphere will have > 60 % energy conversion using the existing high energy free space based electrons. All other proposed solar panel space based technology must be launched 22,000 to 38,000 miles to GEO which increases the cost a 1,000 fold, uses poor energy efficiency solar panels becoming even less energy efficient because of the inverse square law. Definition example of inverse square law of physics, the intensity of radiation from the Sun is 9140 watts per square meter at the distance of Mercury (0.387AU); but only 1370 watts per square meter at the distance of Earth (1AU)—a threefold increase in distance results in a ninefold decrease in intensity of radiation. It also needs to be pointed out that the point source area increases significantly. For example, The energy or intensity decreases by a factor of ¼ as the distance r is doubled, or measured in dB it would decrease by 75% or 6.02 dB ( 3dB is 50% power loss).
This is the fundamental reason why intensity of radiation, whether it is electromagnetic or photonic radiation, follows the inverse-square behaviour, at least in the ideal 3 dimensional context (propagation in 2 dimensions would just follow an inverse-proportional distance behaviour and propagation in one dimension, the plane wave, remains constant in amplitude even as distance from the source changes).
The loss from a GEO solar power satellite would be so diffused in intensity to almost making it useless as a reliable power source.
The major problem for MPTS is that at 17,000 miles an hour in LEO the MPTS satellite can only transmitt to any one attenna for 2 to 3 minutes so it would be necessary to construct a power gird of hundreds or thousands of antennas similar to a rail road track layout. The 15 ft diameter parabolic microwave receiving attennas made of fibreglass would collect the microwave energy from the satellites as they go whizzing by in LEO. An attenna array from tens of miles to hundreds of miles would convert 24 x 7 hundreds of Gigawatts an hour of low cost microwave power energy to its customers.
The 200 mile LEO microwave power transmission satellite MPTS has none of the solar power satellite disadvantages. All project planning for space power satellites use microwave transmitters made with lasers, klystrons, magnetrons, photo electric converters, or traveling wave tubes. The major problem with klystrons, the preferred microwave power device by MPTS is that the cathode fails from electron depletion and while magnetrons and traveling wave tubes offer a little longer lifetime before failure the performance is limited by the low power they can finally transmit.
Also the recommended transmitted microwave frequencies should be kept at about 2.4 GHz. due to refraction by the Earth’s atmosphere. Laser power transmitters have also been proposed but due to the severity of laser light refraction and power loss through clouds lasers have been seen as less desirable. The last method which was proposed by Nikola Tesla now in study by MIT and others is wireless power transmission. The method of having two resonating tuned electronic circuits which can transmit power over short distances rules out space operation as the power transfer is less efficient than microwave.
In contrast, the microwave power transmission satellite MPTS with its new unique patent pending concept of using Ionosphere free space electrons, with LEO orbit as the preferred orbit, and phased shifted microwave signals offers a unique approach to controllable high energy power transmission from a space based satellite to an array of hundreds or thousands of antennas in series/parallel feeding a power grid consisting of hundred of power receiving conversion stations across the country. In the future it will also be possible to use a klystron with free space electrons feeding the cathode for a much higher electron amperage source while extending the life of the klystron many years. The present invention will allow for a high power microwave energy transmission method to Earth preventing any future major energy disruption or terrorist threat to the United States and the rest of the world.
The invention relates to a novel satellite using a free space electron feed klystron, and more particular, a satellite that is able to use these electron particles accelerated to 99 percent of light speed as a source for high energy microwave transmission and a propellant for maintaining the low earth orbit of the satellite. The prototype itself contains small, sealed, transportable, autonomous satellite which will provide reliable energy from LEO 24 hours a day, seven days a week, 365 days of the year for at least 10 years or greater of 100 Megawatts or 877 Gigawatts a year per satellite of microwave energy transmission to receiving antennas on Earth. The microwave energy from the prototype satellite will be the source of uninterruptible high power electrical energy to energy conversion sites.
The F2 free space electron density varies around 1012 e/m3 at 300 km height from Earth. The F2 Ionosphere electron temperatures vary from 1000 K to 3000 K where the mean thermal speed is 200 Km/sec and the electrons have a Mev to Gev potential. When collected by the satellite collector screen the free space electrons will supply high quality energetic electrons as a source of renewable thermionic electrons to the klystron cathode and supplemental power to the satellite. Increasing the amount and energy level of the electrons supplied to the cathode by free space electrons will increase the maximum thermionic current density and increase the total current supplied by the klystron allowing the klystron to produce significantly higher energy microwaves well beyond the original invention design gains specifications.
By using free space electrons the lifetime to failure of the klystron can be extended thousands of times its normal usage, a major problem preventing the successful implementation of space power transmission from satellites to Earth. All klystrons to date have a typical 5,000 hour cathode lifetime before burnout due to electron depletion of the thermionic emitter materials. This major hurdle to wireless power transmission from space can now be overcome with the use of free space high energy electrons providing the necessary energy for the prototype klystron to reach >100 Megawatt microwave power outputs with the possibility of Gigawatt klystrons in the future while extending the lifetime of the thermionic cathode component preventing total loss of the satellite. Microwave power can now be beamed to the receiving station 24 hours a day 7 days a week for tens of years.
There are many major advantages for operating a microwave power transmission satellite in outer space as the solar light can be converted more efficiently to electrical energy for satellite operation. The electrical energy supplied by the 400 meter 250 kilowatt $ 60 million 1,000 pound solar panel array will provide the necessary operational energy to the satellite and high power klystron microwave system. The microwave phased array antenna electro magnetic frequencies will work together to create a variable angular pitch virtual waveguide in space for the path of the near light speed propellant electrons and a non mechanical means of changing the microwave beam angle to the receiving antenna microwave conversion station.
A satellite using electron subatomic beam particles can be accelerated to over 400 thousand electron volts having a thrust of greater than 88,000 horsepower. It can therefore be shown that the kinetic energy of the high velocity electrons having mass, i.e. E=MC2, can be used to maintain a satellite in low earth orbit (LEO) or propulsion to some other interstellar position. An equal and opposite force will thereby be applied to the satellite aft according to Newton’s Third Law of Motion.
This method will allow the satellite to stay in a precise low Earth orbit (LEO) countering the effects of Earth’s gravitational pull and other miscellaneous frictional forces acting on the satellites preferred orbit. All prior world wide aerospace designs of the ISS and satellites looked at free space electrons as bad contamination called space craft charging and a precursor to ISS or satellite destructive damage and much effort was and is given to ridding the ISS or satellites of these electrons.
Today’s space power systems proposed by all others talks of cost in the $ billions even $ trillions of dollars. The prototype unit cost per LEO satellite of $ 1 million or less for a microwave power transmission satellite (MPTS) that will use these free space electrons as an infinite renewable high energy source for the earth and future space exploration is more inline with logical costs. Comparison cost just with the investment in the US Nuclear Power Industry would equate to >>>1640 LEO satellites producing greater than >>164 BILLION watts of power 24 hours a day 7 days a week. With the addition of many more satellites the energy output to Earth goes up dramatically.
When one part of the Earth goes into darkness a World Power Internet Grid analogous to the Alaskan pipe line and internet going from Asia to North America to Europe and other countries all inter-connected could continue to supply thousands of Gigawatts of power to the planet. As the LEO satellites enter the dark part of earth the free space electrons will continue to supply electricity to the LEO satellite for power transmission to Earth 24 x 7. The possibilities are endless and only need mankind's genius and ingenuity to make it reality.
Using the US average cost of $.05 Kw/h for electricity to homes in America this would calculate to a gross profit from 1 year of operation of $ 44 Billion/year, essentially paying the cost of 1 satellite thousands of times over. It would also be conceivable for 1 satellite to create >$ 1,000,000,000,000 profit (1 Trillion) in its operating lifetime.
Space base power is seen as a viable alternative to man’s need for energy and the need for security of our country from terrorist taking control or destroying the present oil / hydrocarbon dependent economies of the world. Japan for example, is investing Billions of dollars and plans on investing Billions more money in this kind of technology than any other know to man.
Another more sinister problem is that of the current practices for supplying energy to the planet with hydrocarbon energy sources that are not renewable and pollute the planet. Earth based wind power and solar power will not be able to meet supply energy demands, is unreliable do to changing weather conditions, and will effect food production and other animal and plant life. US nuclear energy plant cost now at $ 492,000,000,000 will not be able to supply future energy needs and has the added problem of radioactive nuclear waste contamination of thousands of years and dwindling nuclear material reserves.
All other proposed energy sources in research and development have major environmental problems and are still not renewable energy or reliable. The desalination of the ocean for fresh water - cheaply, anywhere forever and an electrical power grid for cars, homes, hospitals, ships, trains, etc. - clean energy.
The best of all possibilities is this new cost effective renewable energy source that doesn’t destroy the planet, allow countries and terrorist to threaten world peace, and will prevent further hydrocarbon green house gases from being created…….. Killing our planet and its people.
