  1. Re:Lower and raise the orbits on Low Earth Orbit Junk Yard Nearly Full · · Score: 1
    Going lower than LEO is not really practical. There's already enough air resistance there as it is.

    If that's how you define "LEO" then of course -- you've defined the orbital debris problem out of existence by adopting my proposed solution. Accepted definitions of "LEO" do, however, vary from altitudes where resistance from upper atmosphere is significant to altitudes where it is _not_ significant.

    And the cost of additional altitude is not actually that low; gravity in LEO is still 88% of what it is on earth. Sure air resistance is a big factor, but that doesn't make drastic orbit changes free, especially considering installations already in place (such as the ISS) are not fitted to just move around.

    No one said "free" but the cost is "very low" to gain altitude. The cost to place mass in a 200km LEO orbit is about 1/2 the cost to place mass in a 20,000km GEO orbit. Do the math. Moreover, the potential gains in economy are even greater by using higher Isp technologies with lower thrust and yes this is directly due to the absence of atmosphere at perigee, where you do the transfer burns.

    People seem to have a very Star-Trek view of orbital dynamics. You can't just drive around willy-nilly. You said it yourself: Space is big... really really big.

    Grow up.

  2. Lower and raise the orbits on Low Earth Orbit Junk Yard Nearly Full · · Score: 1

    Much of this can be ameliorated if not solved outright by launching only to lower and higher orbits. Lower orbits will be in the upper reaches of the earth's atmosphere which will clean out debris naturally. The orbital decay of the satellites can be matched to their expected operational lives and if launch costs can be brought down then additional station-keeping fuel can be placed aboard to help maintain the operational life until it is time for burn-up. Higher orbits will be in a volume of space that is vastly larger than the LEO shell now being threatened with overpopulation by debris. Space is big... really really big... All you need is to extend the orbital altitude and you reduce the problem as a cube of the orbital radius -- but the cost of additional altitude is _very_ low compared to simply getting to LEO altitude. Once again, lowering launch costs helps here.

  3. You mean NASA is going to follow the law? on NASA May Have to Buy Trips to Space · · Score: 4, Insightful

    Ever since the Launch Services Purchase Act of 1990 (PL101-611) NASA has been required by LAW to purchase all launch services from the private sector that could be reasonably provided by the private sector. As the person who testified before Congress about the passage of that grass-roots law I was fairly galled by the invitation I received a few years later from NASA to sit in the VIP stand and watch them launch the Advanced Communication Technology Satellite upon a shuttle. Well, actually, by that time I had somewhat come to expect that it was hopeless for a grass-roots legislative effort to actually have an impact on a governmental behavior but to actually receive an invitation to see them blatantly violate the clear intent of the law was still annoying.

  7. Still no fusion prize on The Role of Prizes In Innovation · · Score: 2, Insightful
    Fusion energy prize legislation was drafted 15 years ago and submitted to Congress by one of the founders of the US Tokamak program, Robert W. Bussard. There is good reason to believe this legislative proposal was a precursor to resurgence of interest in technology prize awards later in the 1990s.

    More recently, Dr. Bussard gave a talk at Google HQ about his currently favorite fusion technology and it has caused some commotion.

    You said: Perhaps you intended to suggest that it's reasonable to charge a use fee for services that wouldn't happen without government, but it came out backwards.

    No I said it correctly and you read it backwards.

    "Property rights that would not exist in the absence of government" are, collectively, the service that "wouldn't happen without government".

    That's what I said the use fee, aka net asset tax, should be applied to. Once you understand this it is clear why it is the proper basis for revenue for the government.

  11. Re:Get to the root: Tax net assets on The Return of the Fairness Doctrine? · · Score: 1
    I should add that once the government assesses your property, it is putting up a bid price and you can force the government to fork over the bid price in exchange for the loss of ownership of your property. Presumably the government wouldn't bid a price that it couldn't immediately get in liquidation itself unless it was trying to overassess you.

    Also, the way the definition of "subsistence assets" would be defined ultimately would be a single dollar amount, independent of any specific location's cost of living. With the citizen's dividend you are far less constrained in where you can locate so you subsistence basically becomes median price of a house for a household of your type, plus the median capitalization of a job.

    Tax net assets, in excess of subsistence, at the same rate as the rate of interest on the national debt. All other domestic taxes are repealed. Net assets are calculated as assets minus liabilities. Asset value is are assessed at the liquidation value. Liability value is assessed as the liquidation value of the debt instrument representing the liability. Liquidation value is set to the higher of either the government's bid for an asset or the owner's ask value. The government is required to take ownership at its bid and the owner is required to relinquish ownership at the owner's ask value. Liquidation value is also used in eminent domain proceedings to define fair compensation.

    When I said "property rights that would not exist in the absence of government" I implicitly stated that the property rights relied upon by a yeoman class would not be taxed. Subsistence properties are maintained by their occupants prior to government support of those property rights. Its why things like chapter 13 bankruptcy protection cannot confiscate home and tools of the trade, or why there are institutions like the FDIC or why the SEC has a minimum net asset level of around the same amount to qualify as a risk investor.

    The tax is necessary since the economic rent of wealth holders amounts to welfare for the wealthy -- a much worse policy than welfare for the poor since the wealthy are the economy's primary decision makers and we can ill afford to corrupt them through welfare. If the rent thereby taken is more than sufficient to support property rights then the remainder should not be held under the control of an elite few politicians lest we end up with the equivalent of central economic planning. Just disperse it evenly and the corruption is minimized while tending to create a yeoman class interested, to that extent, in the common welfare of all.

    People keep targeting the wrong problems since they can't get to the root problem: Concentration of wealth.

    There is every reason to charge a use fee for property rights that would not exist in the absence of government and very little reason to tax domestic economic activities.

    The failure to tax the right thing results in an accumulation of wealth in the hands of those already wealthiest and this results in increased centralization of ownership of everything including the means of indoctrinating the populous.

    Moreover, as people increasingly recognize on both the right and left, it is important to avoid replacing centralization of wealth with centralization of political control. Tax revenues should be evenly dispersed to the citizens without any prejudice in a citizens dividend so they can enjoy the kind of yeoman class independence that created people like Newton and the Wright Brothers.

  18. Universes and Universal Turing Machines on The Trouble with Physics · · Score: 3, Interesting
    An hypothesized (meta)algorithm running our universe has been proposed in "The New AI: General & Sound & Relevant for Physics" by Jürgen Schmidhuber of Dalle Molle Institute for Artificial Intelligence:
    "Systematically create and execute all programs for a universal computer, such as a Turing machine or a CA; the first program is run for one instruction every second step on average, the next for one instruction every second of the remaining steps on average, and so on."
    This actually computes all universes -- not just ours. It also computes what might be thought of as nested universes, giving rise to the idea promoted by Smolin that some universes might be more prolific than others. Among the consequences of this hypothesis is:
    "Large scale quantum computation will not work well, essentially because it would require too many exponentially growing computational resources in interfering 'parallel universes'".
    Prof. Schmidhuber's post-doc student, Marcus Hutter, of Hutter Prize for Lossless Compression of Human Knowledge fame came up with some of the key breakthroughs in "The New AI" upon which Schmidhuber's hypothesis is based.

It is criminal to knowingly use the H-1b visa to lower US wages and that is clearly what happened from 1995 to 2005: A lowering of real wages, ie: wages adjusted for the cost of reproduction (survival is mere existence, reproduction is life).

    The DotCon bubble raised and then lowered wages back to their pre-1995 levels but at the same time real estate -- the primary cost of reproduction component -- went through the roof driven largely by demand placed on real estate by "temporary" workers who, due to better ethnic networking to hold onto scarce jobs during hte the purging of US workers that occurred during the DotCon bubble collapse, have now virtually take over the US IT industry and are becoming permanent real estate holders.
