Design to cost goalspower Sat solution:
• Raise millions of tons a year to GEO at a cost of less than $100/kg
• Space based solar power for a 1-2 cents a kWh, synthetic fuels made from that power for $1 a gallon (easy)
• Excess energy (300TW-years) to put carbon back in the ground if we need to
• Danger of storing 470 cubic km of CO2• We know how to make synthetic oil

$40 billion for the lasers• $60 billion for the rockets• Long build up time to get the lasers
installed and focusing mirrors in place, limited bootstrapping possible (does meet <$100/kg)
• Not impossible, but not compelling• Can we improve on the ISP of the
first stage and reduce front end cost? Yes!

Skylon and Lasers
Takes off from runway, 12 t to LEO
![Page 21: A Comprehensive Approach to Carbon and Energy Problems](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568155c0550346895dc39236/html5/thumbnails/21.jpg)
Laser stage 12 t• Mass ratio 2• 6 t propellant, 6 t payload• LEO to GEO 4.1 km/sec• Modest ISP of 600 • 6MW of laser, $60 million
takes 24 hrs LEO-GEO• First mirror is a problem
![Page 22: A Comprehensive Approach to Carbon and Energy Problems](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568155c0550346895dc39236/html5/thumbnails/22.jpg)
Eventually (after much buildup)
• 50 t laser stage, 25 t payload to GEO
• Skylon sub orbital, contributes 4-5 km/sec delta V
• 8 GW laser (8 years @ a GW/ year) contributes 9-10 km/sec
![Page 23: A Comprehensive Approach to Carbon and Energy Problems](https://reader035.vdocuments.mx/reader035/viewer/2022062816/568155c0550346895dc39236/html5/thumbnails/23.jpg)
After 8 years, a Skylon flight every 15 minutes
• 96 flts/day, 60-100 rockets• 800,000 t/year to GEO• Growth with more laser• Skylon life up to 500 flights• Fleet size at 1.5 flights/day• Other sub orbitals work too

Cost/kg to GEO
• Initial figured at twice the per flight depreciation of a $450 M vehicle and 6 t to GEO ~$750/kg
• Mature figured at twice the per flight depreciation of a $292 M vehicle and 25 t to GEO ~$46/kg
• Design to cost goal met <$100/kg
