Yah, it really was an amazing accomplishment. Just
goes to show what a bunch of dedicated engineers can
do when they have enough money tossed their way.

The only thing O'Nielle forgot was that politics can
ruin any good idea, given that it might get someone
elected, which is exactly what happened when Tricky
Dicky decided to gut the "Democrats" great vision.

I fear O'Nielle was an optimist. Ah well, so am I,,,

While we can probably agree that Nixon was less-than-nice (I found the revelation that he had refused to allow the carrier John F. Kennedy to pick up the Apollo 11 crew particularly galling), I don't think he was entirely to blame for what happened to NASA after Apollo. The plain simple fact of the matter is that the American people no longer cared. Like any politician, he merely responded to the public trend. We can be grateful that by approving the Shuttle, he at leastdeclined to eliminate the manned space programentirely.

NASAs avowed purpose is research and exploration,
something they've done pretty darn well.

To do the things we(SSI proponents) want requires
research and development, with the accent on
development.

That seems best done by a commercial interest in
space, which is the major way we have of deciding if
something is worth doing at all, ie, is this
investment worth my effort?

Return on investment is how we keep score. The
POTENTIAL returns on space development are so
enourmous as to boggle the mind of Midas, but
convincing people to invest their hard earned cash is
really hard,,,but, it can be done,,,

I guess I can accept that reality Mike, I just have a
negative bias toward Nixon.

It's really bugged me that he seemed the principal
negator of the High Frontier. I was so excited by the
space race, I thought it would mean I could expect to
really go to space myself. Now it appears I won't make
that trip in my current incarnation,,,bummer,,,

At most, we can only say he canceled Apollos 18 - 20, or that hedeclined to pursue post-Apollo lunar programs.

I think there were two principle negators of High Frontier:
1. The Shuttle not living up to its initialpromise, which meant that the original costs estimates and schedules were too optimistic.
2. The sudden resumption of cheap oil from the Middle East, which undercut SPS which was the principle economic foundation for High Frontier.

Now, any current causes for optimism on these two fronts? Consider:
1. There is a plethora of new space companies working onspacecraft for tourist applications. While these vehicles are suborbital, they might advance to orbital in gradual increments, bringing airliner-like development and operations to spacecraft for the first time in aviation history.
2. In addition to concerns about enrichingnations which support terrorism, we're also increasingly concerned about greenhouse gas emissions. SPS is the only potential replacement for fossil fuels which doesn't have an attendant waste disposal problem.

Not the only one -- if Bussard's recently revealed approach to
proton-Boron fusion can be made to work, then this would produce
abundant energy with no radioactivity (the only outputs are helium and
electricity).

This is unlike the tokamak approach to fusion, which does indeed
produce radioactive wastes (though ones with a much shorter half-life
than the waste from typical fission reactors).

I've long been a skeptic of fusion, and I'm still a skeptic about the
tokamak approach. But I'm cautiously optimistic about Bussard's new
approach (see references below). We shouldn't despair about this,
either -- if this form of fusion works, it can be used to produce
rocket engines thousands of times more powerful and efficient than
anything we have today, and would so dramatically reduce launch costs
and in-space transit times that I suspect the solar system would open
up to us almost overnight.

Keep your eye on this technology -- it's still unknown who is going to
pick it up and run with it, and how. But I think someone will. The
next step is to wait for the technical paper Bussard is preparing,
which will lay down all the theory and experimental results. Then I
imagine we'll see other groups (such as the U. of Wisconson folks)
attempting to reproduce his results. And if his results are confirmed,
somebody will step in and aggressively pursue it -- and I bet it will
be a company, rather than the government, that will be first to the
punch. Of course all this is speculation, but that's my guess.

Best,

Be careful. I think that these kinds of non-market considerations are
exactly the kind of top-down calculated-instead-of-discovered-price
thinking that has sidelined what might have been the space development
business for the last few decades. Sell people more of what they want to
buy *now*, not what you *think* they'll buy in the future, or, worse, what
you think they "should" buy, especially if the proposed hair-shirt in
question is supposed to be "good" for them.

Mrs. Smith didn't raise her son Adam to be no fool, and all that. Count on
enlightened self-interest -- hell, pure self-interest -- to guide you at
all times, and let time wound any invisible "externality" heels as they
manifest themselves.

For instance, what always drives technological innovation in aviation is
not slipping the surly bounds of earth, but cheaper coach fare to Cleveland
- -- and mo' better bombs in the laps of the bad guys.

We already have airliners that can do 'teen-hour-plus death-marches to most
of the globe (747/777, various Airbussen), and soon we'll have commercial
airliners that will do non-stop geodesic, but still-death-march transport
from any point on the globe to any another (787s to start). Anybody who can
do the same faster for roughly the same money is always going to do better
than anyone who doesn't. And, to malaprop a famous space-activist, you're
only half-an-orbit to anywhere...

So, creep, crawl, walk, run.

Remember that commercial aviation, all the way back to the Wright Flyer,
started as a quasi-circus attraction, with barnstormers buzzing small
towns, wowing the "rubes" with a loop and a roll or three, and taking
various "worthies" up for a ride in exchange for cold, hard, cash.

It's ugly, but it does have precedence, and, apparently, it works. :-).

Cheers,
RAH
Who remembers also that government regulations, at the beginning of World
War I, required that all military aeroplanes must fly as straight and
level, with as few banks, climbs and dives as possible at all times, and
certainly no loops, rolls, or other such frivolous nonsense. That worked
just fine until people started shooting...

All of the Middle-East arguments and environmental arguments in the world wouldn't equal the significance of SPS underselling fossil fuels by a penny a kW. Unless... If the economic effects of global warming were precisely calculable (not trying to argue they are, mind you),some people would advocate a "carbon tax" being levied against use of fossil fuels. That might not fly politically, but if such a situation did come about, SPS might become competitive with fossil fuels at least a little bit sooner than otherwise. Similarly, I think if the costs ofwaste disposal and reactor decommissioning were to be fairly factored into theprice of nuclear energy, it toowould face difficulty competing with SPS. An unfair strike against SPS is that all of its costs are up front and obvious. Some of the costs of continuing to use fossil fuels and nuclear power are hidden.

There you go again...

:-)

Seriously, prices are discovered, not calculated.

As for "hidden costs", externalities in the trade, there's always my
favorite Hayek quote on the subject:

"Externalities are the last refuge of the derigistes*." -- Friedrich Hayek

One can always imagine costs, but most of those you can imagine are
incalculable, at best, and, at worst, your calculations produce
un-heh-imaginable results.

I watched the entire presentation. He is a very interesting and
compelling speaker. He knows what he is talking about. Does not come
across as has having any kookiness. In fact he comes across and being
down right grounded in reality, political and physics. It is a sad
commentary on our scientific community that every comment he made is
absolutely true. There is no better way to kill an idea then to bring
it to the attention of somebody who's paycheck is threatened by it. I am
ready to write a check for the little bit that I can get out of my
spouse's clutches for pet projects. We need a support Dr. Bussard
foundation!

There is also a "Space Show" interview with Jim Benson

that is supposed to have some updated information which I have

Also Tom Ligon (who worked on this as a low level employee) posted some
interesting comments to

Bussard is not the only one with an alternative fusion project. Eric
Lerner's Focus Fusion,

http://focusfusion.org

recently received additional funding and is conducting experiments in
Chile.

Further funding depends on reaching "proof-of-concept" levels by Jan.
2008. We should know by then if Focus Fusion has a chance of working.

If Lerner or Bussard can pull this off, it will spur research into
other alternative fusion methods.

No, but personally, he's the only one I believe has a chance of
success. I'm skeptical of the "Focus Fusion" project, but hey, maybe
I'm wrong. For something this important, it's certainly worth a bit of
funding to try, and I'd be happy to eat my words. Either one would be

I would add a couple of comments to Mike's analysis. The decision to abandon SPS funding in the federal government, as described in the book Sun Power, was a political decision driven by the oil, gas and coal interests, not just a reflection of lowered oil prices. A number of administrations share the blame for that decision. As for the current energy situation, the one big factor Mike doesn't mention is the rapidly increasing competition for energy resources on our planet, led by the explosive growth of the Chinese and Indian economies. More energy is going to have to come from someplace--it's our job to make sure that SPS is that place.

Careful, Mike. Suggesting that NASA is, was, or ever could be
anything other than some evil force for evil evilness will get you in
trouble with some people.
