I am planning to float the following idea before some Congressional aides I have met (comments invited): Congress would establish potential guarantees in the amount of $1 billion or more for the transport of water or equivalent payloads to LEO at a price not to exceed $2000/kg. These market guarantees would be open to any and all companies that are able to deliver--not promise--at that price or lower. Lower prices would enjoy higher priority in accordance with an economic elasticity of 2. For example, a company delivering water (or equiavalent payload) for $500/kg would be paid for eight times as many kg of water than a company charging $2000/kg. The water would be available for electrolysis into propellants for deep-space exploration--the cost of which should be highly dependent on the cost of propellants in LEO. Within limits, NASA could specify other payloads in terms of water equivalent; however, the launch company would have the option of delivering either water or the equivalent payload. This plan takes the bureauracracy out of the decision loop as to which companies get business. Any company of any size could compete for the guaranteed business. This plan also prevents all of the gaurantees being soaked up by cheap promises. Performance, not promises, would count. No money would be paid out--or even committed--except for actual performance. Excellent concept. That is a level of service private companies are ready to deliver. This would give startups experience with the now routine procedures associated with launch, rendezvous, and docking; while not requiring the non-routine capabilities of carrying crews or recovering spacecraft. Look at Len Cormier, for example, who has decades of experience and some very innovative ideas and patents for reducing launch costs and increasing safety and reliability. But he's not independently wealthy (unlike the founders of most other recent space start-ups), and has been entirely unsuccessful finding investment, so his innovative ideas remain unused. That's a sign of an unhealthy market, a situation which NASA could change by simply resigning from the launch business. (posted by Joe Strout). That he can't stay with a design concept more than a few months might also have something to do with it. Investors are wary of someone who can't keep his eyes on the prize for any length of time. There is a proper balance between focus and flexibility. We've discussed this before. IMO, the financial community is much too focussed on "focus"--and too wary of flexibility. There is one thing worse than not getting investors interested in a good project, and that is getting them locked into a poor project. I think that is a fact of life. I have found investors to have a surprising lack of a sense of adventure. Exploration and adventure requires a patron so wealthy that the funding required is mere throw away money. Usually this is not a private entity. In my book, "venture capital" is an oxymoron. Within my limited resources, the best use of my capabilities seems to be improvement on the conceptual design level. As long as there is steady improvement on the conceptual level, there should not be a stigma attached to it. Once serious money is committed, it is time to shoot the engineer--as Dutch Kindleberger used to say. I hope to unveil our Space Van 2010 shortly. If the design and analysis work on this version continues to hold up, I feel that it will be definitely superior to anything that I have done in the past 45 years--and perhaps superior to any other conceptual design of which I am aware. Sounds very impressive, but in keeping with your proposed legislation, have you designed a Space Water Tanker 2010? snip George Evans |

Right now it looks like they could launch about 20,000 lbs into LEO. That's not enough. Not enough for what? CEV? That's right, NASA has carefully designed the CEV to be just out of the reach of any commercial launcher. This gives them apparent justification for developing their own launch vehicle. I do NOT buy that this was a necessary decision, however; more numerous, smaller launches could have done the job, with far more robustness and without the need for NASA to have its own launchers at all. (But that would not satisfy their political requirement to keep large armies of rocket builders & maintenance staff employed.) It's not like NASA needs a car to drive down the road. It can't go out and buy a launch because no one makes one. Nonsense. Several companies offer very capable launch services. They are doing things for which vehicles have not been designed. They are choosing to do things, by design, for which current vehicles are too small. I wouldn't want missions constrained to designs that fit within packages available on the market. Why not? If those constraints result in more frequent launches, a more modular mission design, a greater number of actual accomplishments for the same NASA budget, and lower launch costs for everyone, then what's the problem? (Apart from the large number of unemployed NASA workers, of course.) They've had their ups and downs. From what I have read recently including the CAIB report, the shuttle program saddled them with an impossible task--making "all the people happy all the time". So I can see how someone could have your opinion over the past few decades. OTOH, I think NASA did a lot of innovation in the process of almost accomplishing the impossible. Me too. I respect NASA; I just think it's time for them to get out of the launch business, and I'm deeply saddened to see their renewed refusal to do so. ,------------------------------------------------------------------. | Joseph J.

Thanks, George. I do plan to float the idea before some appropriate congressional aides--so any further ideas would be welcome. I have purposely avoided the specification of orbital inclination, although I think altitude should be at least 450 km. One aspect of the plan that I did not elaborate on before, was the non-interference with NASA's present plan. I understand that Griffin is rightfully reluctant to support ideas that would conflict with NASA's basic plan. If there are no companies capable of delivering water or equivalent payload at low cost, then this should have little impact on present planning. However, the unplanned availability of perhaps 1000 tonnes, or 10,000 tonnes, of water in LEO should open up a lot of new possibilities for NASA. .......snip IMO, the financial community is much too focussed on "focus"--and too wary of flexibility.

I thoroughly agree. ....snip Sounds very impressive, but in keeping with your proposed legislation, have you designed a Space Water Tanker 2010? There are two basic versions. One is a space tourism version with an oversize cabin to allow zero-g play for about 11 orbits--without an immediate need for a small orbital hotel. This version has two pilots, a flight attendant and provisions for eight passengers. We hope to cover operational costs and ROI at a price of $1 million per flight--or $125,000 per passenger. The second version is a cargo version with a single pilot and an oversize cargo bay--the theory being that volume is just as important as mass for prefab modules. At the present time, it looks like cargo payload will be about 1500 kg to a 60 degree, 450-km. We could back off a lot on cargo bay size for water tanker missions. Besides tourism, we see a "huge LEO" telecom system as being economically feasible with mass-produced telecom\ satellites. Performance and economics should be vastly superior to any of the big-LEO systems that have floundered because of poor performance and high cost to the consumer. Like previous big-LEO systems, the required investment is huge. However, proof of concept might be as low as $250 million: $200 million for the SV 2010, and $50 million for a few proof-of-concept satellites. With 4096 satellites, one is overhead at all times. Capacity is enormous and signal strength is as much as 32 db better than Iridium. Even at partial capacity, cost of the space segment to a subscriber could be quite low for unlimited use of a 20 kHz channel in L-band. BTW, the Space Van 2010 uses only LOX/kero in both stages. It looks like we can avoid using hydrogen even as a tripropellant concept. Our patent-pending "kite plane" approach plays a key role--even though we now have ultralight, low-stressed metallic skins and stage at about mach 4.6 and 70 km. snip George Evans Best regards, Len (Cormier) PanAero, Inc.

Check out the University of Wisconsin web site. What a wonderfully non-precise reference. How about you give a URL with this mythical claim of a working, greater than breakeven, 3He-burning, reactor demonstration? I suggest you are misremembering a web page that talks about a concept that might work, maybe, if someone built it (unless it's that IEC concept, which is known to not be workable as a power-producing reactor, even with DT.)

However, I'm thinking it'll be worth nearly a trillion per year by the time we've sucked most of our oil wells dry and having dug up that last quality tonne of accessible though still downright nasty coal. By then a gallon of gasoline should be worth $100 if not $1000, with most all other fossil energy related products and services as equally impacted, if not worse off. Of course, if someone actually had the LSE up and running, at least then getting whatever safely and efficiently over the tether distance of 64,000 km, such as transporting to/from the lunar surface and that of utilizing the massive CM/ISS should do quite nicely without involving any of those spendy and somewhat testy fly-by-rocket landers that haven't even been R&D prototype proof-tested as we speak. ~ Life on Venus, a township w/Bridge & ET/UFO Park-n-Ride Tarmac: http://guthvenus.tripod.com/gv-town.htm The Russian/China LSE-CM/ISS (Lunar Space Elevator) http://guthvenus.tripod.com/lunar-space-elevator.htm Venus ETs, plus the updated sub-topics; Brad Guth / GASA-IEIS http://guthvenus.tripod.com/gv-topics.htm Earth resources are dirty, both to use and store the waste. Oil is running out and coal will too. It is time to find new energy sources. He-3 is clean and powerful, fully capable of energizing the U.S. grid. The Moon has 100 million tons of he-3 ready and waiting. Solar power is clean and becoming more practical with improvements in solar cell efficiency. Hydrogen is clean and can take the place of gasoline for cars. Microbes can convert methane into hydrogen. We have plenty of methane. He-3, solar power, and hydrogen are my 3 top picks for new energy sources. Each could be on line in 10 years. tomcat |

Very good mindset that'll save humanity from itself, but don't leave out a considerable degree of wind-energy conversions or that of having to store whatever the surplus of such squeaky clean and renewable energy as H2O2. With H2O2 we could then cleanly burn the likes of corn or even oily dirt, or that of the worst quality of coal at a fraction if any atmospheric consumption to boot. H2O2/aluminum also makes for one hell of a nifty battery energy density, that's every bit just as clean and renewable unless we keep using using up our limited reserve of aluminum for accommodating those rather massive SBRs. ~ Life upon Venus, a township w/Bridge & ET/UFO Park-n-Ride Tarmac: http://guthvenus.tripod.com/gv-town.htm The Russian/China LSE-CM/ISS (Lunar Space Elevator) http://guthvenus.tripod.com/lunar-space-elevator.htm Venus ETs, plus the updated sub-topics; Brad Guth / GASA-IEIS http://guthvenus.tripod.com/gv-topics.htm |

If the plan fails, it has no impact on NASA. If the plan succeeds, does it: A: Make NASA look stupid, having invested in HLV etc to get to the moon. They now need to completely revise their architecture B: Enable NASA to continue with Constellation but at a much reduced cost / enhanced capability, by reducing the costs of the basic low value components, whilst maintaining NASA's ability to launch the precious stuff on the Stick. Provision of water creates problems of electrolysis and pumping. Would not hydrogen and oxygen be more useful? That can be made into water and power, or used as rocket fuel. Or perhaps Kerosene and LOX? An initial market might be to replace the EDS with 20 ton flexi rocket modules. Private contractors would deliver these for under $40 million (in your figures). A simple design would only add a few million on top of that. Three of these would be attached to provide the Earth Departure and Lunar Insertion Stage. Manwhile, one or two Sticks, and no HLV, would bring the precious CEV and Lunar Access Module. The beauty of this is that it doesn't rely on simulateneous launches, or in orbit propeallant transfer. Your space station acts as a Rack, on which several Flexi-Rocket-Modules will be waiting. The rack would equipped with a manipulator arm to assemble the components - plug and play, and no propellant transfer. |
