The present invention relates to solar radiation and, more particularly, to a solar parasol and methods of shielding the Earth from solar irradiance.
At Earth's average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by NASA satellite missions. This amount of power is known as total solar irradiance. This heat energy is the largest source of heat warming Earth's surface. Heat is also coming from the core of the earth due to compression of the Earth itself. This heat migrates up through the surface. Heat travels from a hotter source to a lower temperature area. This total amount of heat is transferred to the environment, i.e., our atmosphere, and eventually lost to space. Our planet balances this heat gain with heat loss and yields our Earth's average temperature.
However, the amount of heat lost can be hindered by gases generated on Earth, either naturally or by humans. Several attempts have been made to restrict the amount and number of gases created by manufacturing processes, energy production, or by how we use everyday devices, such as our automobiles and light bulbs. Each hour 430 quintillion Joules of energy from the sun hits the Earth. That's 430 with 18 zeroes after it. In comparison, the total amount of energy that all humans use in a year is 410 quintillion Joules. For context, the average American home used 39 billion Joules of electricity in 2013.
Some practices to harness natural energy are currently impracticable, such as the manufacturing of windmills and solar panels. The cost of their production is either too expensive, or the process creates byproducts that are more hazardous to the environment than they save in energy production. Reducing the energy our Earth receives every hour will help reduce global warming.
As can be seen, there is a need for a device for reducing the amount of energy received by the Sun.
Broadly, an embodiment of the present invention provides a parasol to be positioned in the Earth's atmosphere to reflect solar energy.
In some embodiments of the present invention, at least one solar parasol sits in sun-synchronous orbit, approximately 450 miles above Earth's surface. These solar parasols sit between the Sun and the Earth and reflect the Sun's energy away from the Earth, acting as a shield.
The present invention embodies two (2) deployment phases: phase one is the use of mylar film secured to a carbon fiber frame, thereby defining the solar radiation shield. Deployment of phase one may last for twenty years. Phase two is utilizing and deploying the aluminum panels (approximately 10′ by 10′ panels joined together to form a new solar radiation shield) with a gold and beryllium coating to reflect the Sun's light. Deployment of phase two should last approximately 30 to 40 years.
In some embodiments of the present invention, three solar parasols may block energy from the Sun: two solar parasols located over the North or South Poles, respectively and a third solar parasol disposed over the Earth's equator. The arrangement of the three solar parasols may lower or slow Earth's rising temperature and subsequently lower or slow a rise of ocean levels. The solar parasol located over Earth's equator may stop or slow Earth's average rising temperature.
The equator is zero degrees, and thus the North and South Poles are ninety degrees latitude from the equator. The deployment of the parasols over the Poles should be approximately 80 to 85-degrees, latitudinally, offset from the equator to block the Sun effectively. In one embodiment, the parasol runs for one mile by one mile over the equator. The solar parasols over the Poles are approximately one mile by half a mile, wherein the one-mile parameter extends longitudinally to block the sun rays for approximately 30 seconds. It being understood that the dimensions may be adjusted in different embodiments.
Three solar parasols, being deployed in this configuration will block enough solar energy to stop the current rise of the earth's atmospheric temperature and slow the melting of the polar caps.
The parasols may be made of a large blanket supported by a substrate or frame composed of carbon fiber rods and a positioning system. The positioning system may be controlled by NASA. Parts of the parasol may will be launched into space for assembly. They may then be assembled and positioned outside of or within Earth's atmosphere.
In some embodiments of the present invention, frame may hold a sheet. The equator's frame may be 1-mile by 1-mile, while the polar frame may be 1-mile by 0.5-mile. The sheet may be a reflective mylar film. A positioning rocket may be in each corner of the frame. The positioning rockets assist in maintaining a stable orbit and altitude. Additional positioning rockets may be added to the frame or solar parasol.
In some embodiments of the present invention, the mylar film may be highly reflective. It may be painted or colored black on a surface facing the Earth. The frame may be composed of 25-foot lengths with a twist lock connector between each length. The mylar may be connected to the frame by a hook and loop fastener such as Velcro™.
In some embodiments of the present invention, multiple mylar film blocks, approximately 10 feet and 4 inches by 10 feet and 4 inches, may be connected by hook and loop fasteners. The blocks may be joined to form the sheet. The blocks may also be connected by bolts. The sheet may be one mile by one mile (i.e., one square mile). A surface of the sheet facing the sun may be a highly reflective substance (e.g., mylar film).
As mentioned above, in some embodiments of the present invention there are two phases of placing the solar parasols into sun synchronous orbits. Phase one places the three previously described mylar film solar parasols into orbit between the earth's equator and the sun and between the earth's polar caps and the sun. Phase two will be the placement of aluminum panels constructed to be the same dimension of phase one's panels of 1 square mile panel to be at the equator and two panels at 0.5 square miles to be at each of the Earth's polar caps. These solid panels will be made of smaller panels each peel being constructed at approximately 10′-4″ by 10′-4″. The sun facing side of each panel being coated with beryllium then coated with a highly reflective surface such as a thin gold layer of approximate one gold atom thick. A surface facing the earth may be black and include a lightweight aluminum alloy. The phase two solar parasols will be placed in orbit to be adjacent to the phase one solar parasols.
The parasols embodied in the present invention may benefit Earth's climate by slowing or stopping a rise in global temperature.
In one aspect of the present invention, a method of reducing solar irradiance the Earth receives includes placing a solar parasol in sun-synchronous orbit between the Earth and the Sun, wherein the solar parasol is located over the equator of the Earth.
In another aspect of the present invention, a solar parasol for a sun-synchronous orbit, the solar parasol includes the following: a frame; a positioning system controlling a position of the solar parasol in the sun-synchronous orbit; and a shield covering a center of the frame wherein the shield includes a reflective coating on a surface facing the Sun, wherein the positioning system comprises a positioning rocket on each corner of the frame, wherein the reflective coating is mylar film, wherein a surface of the shield facing the Earth is entirely black in surface color, wherein the shield comprises a plurality of film blocks joined by hook and loop fasteners, wherein the frame comprises a plurality of connecting rods, wherein the shield comprises a plurality of sheets connected to the plurality of connecting rods by way of hook and loop fasteners; and further including a triangular reinforcement plate at each corner of the frame.
In yet another aspect of the present invention, an aluminum parasol positioned in a sun-synchronous orbit, the aluminum parasol includes the following: a frame; and a plurality of aluminum panels interconnected forming a shield that covers a center of the frame, wherein an interconnection between adjacent aluminum panels is formed by hook and loop fasteners or magnets, wherein each aluminum panel has a handle on one end and a lip on an opposing end, wherein each handle is dimensioned to operatively associated with, separately, each lip forming the interconnection, wherein each handle has a lap joint for operatively associating with, separately, each lip, wherein each aluminum panel comprises, along the shield: a coating layer; and a gold film layered over the coating layer, wherein the gold film faces the Sun in the sun-synchronous orbit, wherein the coating layer comprises beryllium, wherein each aluminum panel comprises a heat sink along a surface of the shield that faces the Earth in the sun-synchronous orbit.
