1 Mirrors in Space for Low-Cost Terrestrial Solar Electric Power at Night (Less than 6 cents per kwh) Dr Lewis Fraas JX Crystals Inc July 2012
2 Space & Terrestrial Solar Cost Convergence Convergence Solar Power (GW) LEO Launch Cost ($/kg) Years (2012 to 2022)
3 Revolutionary Concept: Lightweight mirrors in a Dawn-Dusk Orbit beam sunlight to earth PV stations providing solar electricity in evening & winter for 14 hours per day increasing solar power station capacity factor to 60%. Space Mirrors Normal Sunlight
4 Large Terrestrial Solar Fields are being installed but electric power production in evenings & winter is desirable: Photographs of multi MW solar power fields in India, California and Germany.
5 Space Power Beaming Prior Art Concept Very Complex
6 Power Soletta proposed by Dr. Ehricke (Prior Art Concept 1978) Advantage: Mirrors in space beaming sunlight to earth is simpler than converting it to electricity and then microwave beaming it down and converting it back again to electricity. Problems: 1.) 4200 km orbit 2.) Sun s disc size is 10 mrad 42 km diameter spot on earth 3.) 180 GW power station
7 Present Proposal: Put Mirrors in Dawn to Dusk 1000 km Sun Synchronous Low Earth Orbit Advantages: 1.) Sweeps a 10 km wide sunbeam over each point on earth for 2 hours in early morning and 2 hours each evening. 2.) Multiple earth ground stations possible with 5 GW per station.
8 Track for a Dawn to Dusk Satellite (Multiple Satellites will cover all +/-80 latitudes)
9 Proposed Mirror Satellite Constellation This 18 evenly spaced mirror satellite constellation is 1000 km high in a sun synchronous orbit around earth with a 30 degree latitude and longitude view. 30 degree longitude equals 2 hours. N is up. The circle represents the earth s surface at 35 o latitude. As the world turns, the target ground station moves up and the slant angle and slant range increase. 15 o represents 1 hour. When the slant angle is 45 o, the earth has turned 13 o or 60x13/15 = 52 minutes. The mirror satellites can be gravity stabilized as illustrated. Here, the mirror satellites are very simplified and exaggerated in size simply to illustrate a concept.
10 Space Mirrors Add Solar Energy 12 in Morning and Evening Power Space Mirrors Normal Sunlight Time
11 Mirror Satellite Concept Gravity Beam Earth (Z) Velocity (X) Sun (Y, Z) A satellite mirror element is shown with 0.25 km diameter mirrors. The NASA ISC SPS assumes 0.5 km diameter mirrors. This MiraSolar satellite element can serve as an initial test article as well as a repetitive building element. Each mirror satellite will contain a very large number of mirror elements each of which can be individually pointed at the center of an earth target solar field. Each MiraSolar satellite can be built up from multiple mirror segments. Four hundred segments in a linear sequence will produce a 10 km diameter 1 kw/m2 sun beam.
12 Solar Electric Ground Stations in 2022 (5 GW each PV or CSP) 1.) LA, San Diego, S. Ca. 2.) Hawaii 3,) Albuquerque 4.) Phoenix 5.) Las Vegas 6.) El Paso 7.) Alaska 8.)Calgary 9.) Denver 10.) Kansas City, St. Louse 11.) Miami 12.) Boston, N.Y., N.J. 13.) Mexico City 14.) Panama 15.) Rio de Janeiro 16.) Brasilia 17.) Lima Peru 18.) Buenos Aires 19.) Madrid 20.) Rome 21.) Berlin 22.) Istanbul 23.) Moscow 24.) South Africa 25.) Saudi Arabia 26.) Bombay 27.) Calcutta 28.) Bangkok 29.) Manila 30.) Taiwan 31.) Sydney 32.) Tokyo 33.) Beijing 34.) Tibet Plateau 35.) Inner Mongolia 36.) Cairo 37.) Delhi 38.) Perth.
13 Revenue Projections for Mirror Satellite Constellations Assumptions ) 18 satellites in dawn/dusk orbit 1000 km above earth. 2.) The sun s disc diameter viewed from earth is 10 mrad. This implies solar spot size on earth from a mirror up 1000 km equal 1000xtan(10 mrad) = 10 km. 3.) Assume each mirror satellites has diameter of 10 km. 4.) Solar intensity = 1.37 kw/sq m = 1.37 GW per sq km. If mirrors are at 45 degrees deflecting sunlight 90 degrees toward earth, the beam intensity directed at earth will be 0.95 GW/sq km. The area of each satellite is π x 25 sq km = 78.5 sq km. The energy in the sunlight beamed down toward earth = 75 GW. Assuming slant range losses, the intensity on earth will be 0.7 GW/sq km. 5.) Assuming that an already installed PV array on earth uses 20% efficient modules and has a ground coverage ratio of 50% and occupies an area with a diameter of 10 km equal to the sun beam size, then that ground station will produce 0.7 GW/sq km x 0.1 x 78.5 sq km = 5.5 GW. 6.) Now assume that in the year 2022 there are 40 ground stations distributed around the world that the 18 satellite constellation will serve and that the constellation gives 1 hr x 0.7 kw/m2 of sunlight to each station in both the morning and in the evening for a total of 2 hr x 0.7 kw/m2 of sunlight per day per station. 7.) Combined, the 40 earth stations will produce 5.5 x 40 = 220 GW. The total energy produced from the sun beamed satellite constellation = 220 GW x 2 x 365 hrs per year = 160,000 GWh /yr = 1.6 x 10^11 kwh/yr. 8.) Assume that the price for electricity is $0.1 / kwh, annual revenue = $3x10^10 / yr = $16 billion per yr.
14 Lightweight Mirrors L Garde Solar Sail 250 m x 250 m at 10 g / sq m
15 Mirror Constellation Cost and Payback Time Projections Mirror Satellite Mass Inputs The mirror weight on the Ikaros solar sail is 10 g / sq m = 10 metric tons (MT) per sq km. The Billman Power Soletta study assumed a mirror weight of 6 MT per sq km (2). Mass of mirror element, L Garde estimate (5): 250 m x 250 m mirror sail at 10 g per sq m = 10 MT per sq km. Assume 20 MT per sq km as goal, then each MiraSolar satellite will weigh about 1600 MT. Mirror Satellite Cost It all depends on launch cost for LEO orbit (Not GEO).The ISC SPS study (4) assumed $400 per kg. SpaceX Falcon Heavy (7) = $1,100 per kg. An AFRL study predicted $250 per kg (8). MiraSolar sat (4) cost $0.6 B; constellation (4) $11 B. MiraSolar sat (8) cost $1.8 B; constellation (7) $32 B. MiraSolar sat (9) cost $0.4 B; constellation (8) $7 B. Payback time range: Assuming 40 ground stations and $400 per kg launch cost: 0.7 years. Assuming 40 ground stations and $1100 per kg launch cost: 2 years.

17 Energy Cost, Start-Up, & Uncertainties 1.) Assuming that the 220 GW ground solar stations will be built for a complete installed system cost of $2.2 per W (DOE projection for 2016) and that they will be paid off over a period of 10 years. then the cost of solar energy without the space mirrors would be 8.6 cents per kwh and with the space mirrors, the cost of solar energy will be reduced to 6.7 cents per kwh and of course there is now more energy at peak demand times in the evening. 2.) There is uncertainty in the projection of the number of ground stations and there are going to be slant range losses as the satellites pass overhead. 3.) In projecting out 10 years to 2022, note that the solar electric power capacity is 65 GW and the annual growth rate has been about 30%. This implies that in 2022, the solar electric power capacity could be 65(1.3) 10 = 900 GW. 40x5.5/900 = 24%. 4.) However, a NASA study assumed 26 mega city sites in 10 years and assuming 40 sites may be optimistic. 26x5.5 = 143 GW in target ground station capacity. 5.) One can easily start with 11 ground stations in the 5 biggest sunny countries in the world: USA, Brazil, China, India, and Australia.
18 Longer Term Economics 12 Space Mirrors Normal Sunlight Deflected sun beams from mirrors in sun synchronous dawn to dust low earth orbit can provide 3 hours additional solar energy in early morning and 3 more hours in evenings to ground solar electric power stations reducing the cost of solar electricity to < 6 cents per kwh.
19 Evolutionary Mirror Design Based on Solar Sail
20 Mirror Billowing from Radiation Pressure is not a Problem Corner Springs The mirror membrane can be stretched flat to within 0.25 degrees With 3 springs at the membrane corners.
21 Mirror Tracking While each hex mirror is larger than the solar array on the International Space Station, the solar arrays are heavier. The moments of inertia and the slew rates are very similar. Hex Mirror: Span = 250 m; Weight = 980 kg ISS Solar Array: Span = 74 m; Weight on SARJ = 8,000 kg SARJ Slew Rate = Up to 30 deg / min Mirror Slew Rate = Up to 45 deg / min Ratio Moment of Inertia SARJ/Mirror = 0.98
22 Road Map & Assembly Sequence
23 Related Space Technology There are already satellites in dawn / dusk LEO orbit Radarsat-1 was launched in 1995 and is still operating in 2012
24 Radarsat-1 in Dawn Dusk Orbit Launch mass (total) 2,750 kg Array power 2.5 kw Launched in 1995 Still operating in 2010 SAR antenna dimensions 15 m x 1.5 m Bus 3.55 m x 2.46 m Solar arrays (each) 2.21 m x 1.32 m Altitude kilometers Inclination 98.6 degrees Duration of one orbit minutes Descending node 06:00 hours Ascending node 18:00 hours Sun-synchronous 14 orbits per day

27 Conclusions The proposed Mirror Sat economics works because the mirrors in space are always available 24 hours per day. For the terrestrial power producing sites, capacity factor is increased by over 50% for high latitudes at almost no additional cost. Ultimate simplicity. Each mirror sat in LEO is no bigger than the 5 km x 15 km NASA ISC proposed for GEO. While expensive, its cost is only 1/20th of the annual US DOD budget and its cost is spread over 10 years. Could catch public s imagination. Connects the space exploration program with the world wide energy future.
