Solar-pumped laser power transmission, a way to dramatically decrease launch costs?
I like this idea, Relatively small mirrors would power
the lasers, not huge solar cell arrays. The lasers would transmit their beams to other satellites that convert it to, and beam it down, as microwaves. No need for mile-size collectors in orbit. Proceedings of the ASCE Earth&Space 2006 Conference April 2006 Space Power Grid- Evolutionary Approach To Space Solar Power "At a higher level, a direct solar-pumped laser could be used to convert solar energy on the LEO satellites, and transmit the laser beams to other satellites where the demand for power is greater (e.g., satellites over the dark side of earth). Recently, development of such lasers has reached a stage where efficiency of up to 38% has been shown. These satellites would receive incoming laser energy using their high-efficiency narrow-band photovoltaic cells, convert it to microwave, and beam it to Earth. This architecture has two advantages: the beaming to Earth could be done at optimal microwave frequencies for maximum transmission through the atmosphere, without requiring excessive transmitter size. The laser beams would propagate with very high efficiency, and require only small collectors. Thus the mass and overall cost per unit power of the system with this architecture may be substantially lower than the lower-risk option presented before." http://www.adl.gatech.edu/archives/adlp06040601.pdf And it should be noted, the SPS start up company, Space Energy Inc, maybe one of the more legitimate commercial attempts at SPS, has as one of it's technical advisors this guy, and his /current/ specialty might be a clue of things to come..... Dr. Richard Dickinson Space Energy Inc technical advisors "Mr. Dickinson is one of the world's foremost experts on Wireless Power Transmission (WPT). President of OFF EARTH-WPT, Mr. Dickinson was Group Supervisor of the High-Power Transmitter Group at Goldstone and was NASA's microwave power transmission specialist on the Solar Power Satellite Reference System team.... ......he is currently involved in studying and designing the solar pumped laser-power beaming phased array for interstellar missions." http://www.spaceenergy.com/s/TechnicalAdvisors.htm s |

No need for mile-size collectors in orbit. 0) Do you know ANYTHING about optics or orbital dynamics? No. 1) Beam divergence. 2) Socket to photon is typically 1% efficient. 3) Lasing media wear out. 4) Conversion inefficiencies. 5) Hardware costs are immense. 6) Alignment specs are unachievable. 7) idiot Proceedings of the ASCE Earth&Space 2006 Conference April 2006 Space Power Grid- Evolutionary Approach To Space Solar Power "At a higher level, a direct solar-pumped laser could be used to convert solar energy on the LEO satellites, and transmit the laser beams to other satellites where the demand for power is greater (e.g., satellites over the dark side of earth).

Whatever anyone else can do, our William Mook can do it better and cheaper, as long as it never involves his own loot. Space Energy seems capable enough and willing to risk at least some of their own loot. I say we give them matching funds so that the public owns 50%. ~ BG |

Their web site says nothing about finances that I can see, but the resumes of the directors are interesting http://www.spaceenergy.com/s/Directors.htm It seems likely they'll know more about money, and how to get it, than about the technology.
