Contractor Proposes Laser Rifles for US Military

The Fryar writes "Well, folks, it looks like the future really is now! It seems the Defense Review has uncovered a submission by Stavatti, a sort of "free market" defense contractor, to the military for a laser rifle. The submission comes in response to the Army's LFLAN requirement - the quest to provide "Light Fighter Lethality After Next" technology, or lasers/phasers/sabers/advanced weapons for use some 20 years down the road. Needless to say, I also considered the category "Star Wars Prequels" for this article."

Under a free market system, every transaction is done on a voluntary basis. Government contracts, on the other hand, represent the exact opposite of free market economics. Government contracting does not represent voluntary association but coercion: The consumer (you and I) do not choose for ourselves whether or not to patronize these businesses. We choose between paying our taxes, leaving the country, or going to jail. This is not market decision but a threat, and hence, the defense contractor does is not a true competitor in the free market.

    Four problems: First, po-210 is rare; in the early days, tons of pitchblende had to be refined to get microgram amounts. Today, we let bismuth-210 beta-decay, which lets us get milligram amounts reasonably cost-effectively, but we're a long way from getting the thousands of kilos that would be needed to power these rifles. It might be cheaper just to build that army of giant robot samurai Bechtel's got on the drawing board.

    Third, of course, is the heat issue: how do you effectively shield the troops from the massive heat source sitting literally in their hands? One of the things that scotched the radioisotope-powered plane was the necessity of constantly ducting away waste energy.

    Fourth is the terrific intensity of the alpha emissions of po-210.

    The TIS-1 Gasdynamic Laser Weapon System will function as a result of gasdynamic thermal pumping of a 10%, 89% and 1% mixture of Carbon Dioxide, Nitrogen and Helium gas respectively. Initially contained at a state of thermal equilibrium at a high temperature (2,173K) and pressure (272 atm) within a gas reservoir heated by a radioisotope power cell offering a high energy density, the gas mixture is permitted (upon release of the weapon trigger) to enter a restrictive nozzle throat annulus whereby the gas will achieve local sonic velocity (Mach 1.0). Exiting the annulus, the gas is permitted to enter a supersonic expansion nozzle, consisting of an inverted aerospike configuration.
    Googling for 'radioisotope power cell' gives several sites including:
    http://cndyorks.gn.apc.org/yspace/articles/amps.ht m
    which describes such a cell to be used for NASA space missions. On that site:
    Each cell will create about 6-8 watts of electrical power and be about 5 inches high and an inch and a half in diameter. Coming up from the bottom will be eight or nine white ceramic tubes wrapped in a metal called molybdenum. Heat - supplied by plutonium -- is applied to the bottom of the cell. The heat vaporizes sodium metal at the bottom of the cell, the vapor then rising into the ceramic tubes. As the vapor reaches the ceramic surface, electrons are freed, which run along a wire that exits the cell, leads to the load and then re-enters the cell. As the electrons flow along the wire, a current is produced and power is delivered. The sodium vapor passes through the ceramic, is recombined with the electrons, hits a condenser and is turned back into a liquid. The liquid is sucked into a wick, returned back to the hot spot and reheated, starting the process all over. The sodium metal will be recycled through the process seven or eight times an hour.
    So in order to produce ~2kW, the cells are going to be BIG - and before anyone points out the 15-25 years bit again, even THESE cells don't exist yet, they are still being developed.

    Looking at Stavatti's claims - the gas reservoir is therefore going to contain plutonium, and gas at 2200K and 270+ atmospheres.

    reloading the powercell must be reasonably easy when you only have a half life of 138 days.

    pressure is immense and boron nitride is not just hard, it is brittle. Protecting against shattering requires a bit more than a little injection moulded plastic. When this high pressure hot gas breaks free it is a good idea to stay away.

    wavelangth is 10.6um which means it will be eaten up by the CO2 in the air so useful range becomes limited. This is not described properly.

    the large wavelength makes for more diffraction but the opening aperture is not stated.

    this wavelength chouce makes locating a shooter relativgely simple, just look for massive re-radiation in the CO2 band.

    of course the massive constant power flux from the Po source makes for nice thermal targets too.

    this wavelength is not eye safe. No, this is not a joke. The snag is that it can then be construed to be a violation of various convensions of war.

    thrust is said to be big, yet recompression is said to be part of the plan in which case most of the recoil should be possible to compensated for. Why is this not mentioned?

    and compression takes a lot of power, where does this come from?

    the gas expansion is likely to cause a hideous noise and makes for even more simple location.

    And so on. I could go on at lengths.

    Inevitably a soldier's laser rifle will get blown up (most likely by friendly fire, judging by the current state of things). There would suddenly be an invisible radioactive hotspot on the battlefield and drifting plumes of radioactive particles. Would all soldiers be forced to carry geiger counters? Would medics refuse to treat contaminated soldiers? Will chem/bio/rad suits become the permanent uniform of our fighting forces?

  53. free market vs. free choice by anonymous+loser · · Score: 3, Insightful
    contracts, on the other hand, represent the exact opposite of free market economics. Government contracting does not represent voluntary association but coercion: The consumer (you and I) do not choose for ourselves whether or not to patronize these businesses.

    In this case, the customer is the government. That's why they are called government contractors, and not citizen contractors. And, yes the government contracting market (by law) is pretty damned free. Anyone is free to bid on upcoming contracts. If you have a small company, there are a number of SBIR (Small Business Innovation Research) contracts available every year, from every department related to the government. The linked SBIR page is about NASA's SBIRs, but there are literally a total of thousands available from DoT, DoD, NIH, NIST, NIMA, etc. If you're a big company, then you go through a similar, yet more formal process to bid on contracts. As is the case with most government-related things, there's more paperwork to complete, and in some cases due to the sensitive nature of the contract, you might be required to have some level of security clearance before you can bid, but other than that it is really wide open. I happen to know of a few recent large contracts that have been competitively bid on by very small companies, so small businesses are not just limited to SBIRs (which are capped at $1M, I believe).

    In relation to your statement:

    consumer (you and I) do not choose for ourselves whether or not to patronize these businesses. We choose between paying our taxes, leaving the country, or going to jail.

    You clearly don't remember history class in high school, or maybe you didn't take it yet. We live in a republic. We elect representatives to make key decisions for us...that's the whole point of a republic. If you don't like the decisions being made, well, that's the citizen's fault for electing a bad decision maker. You are perfectly free to vote, write letters to your representatives, write articles in the newspaper, put up a blog, participate in protests and rallies, and bitch and moan on /. to express your opinion. But please don't complain that you are being coerced and that you have no choice, because you do.

    Human Evolution consists of at least 5 million years (from the moment there were appe like creatures that started to try to walk upright).

    One of the most common traits during the history of humanity is cooperation. Cooperation between human groups is what gave us huge advantages: the young taking care of the old, and that way preserving knowledge for longer, the childless protecting the childs of others increasing the chances of the species as a whole, you name it, you are human so you can find more examples like this.

    It is only when we compete for scarce resources that we turn against each other. The problem is that we are being so succesful that the groups tha lose a showdown can't just move to a different lace and prosper there.

    We exhibit the same kind of violent behaviour as those rats that were allowed to overpopulate in a controlled experiment. All went pearshape: violence, carelessness for the young, killings and in general mayhem.

    Evolution guided us trhough a bening path, it is only our own success and the finite amount of resources in this planet that has determined that we kill each other, but that is not pre-ordainde, if we were wiser we may decide to let the steam off by means of using our brain to go back to our communitary roots as a species.

    If you think of it as an invasion, I suggest you experience some WWII history.

    It's a little late for first-person "experience" of World War II. (Closest you can get is something like "The War 1939-1945," edited by Desmond Flower. Amazing book, mainly because it's almost all first-person accounts and it includes any perspective you can imagine.)

    If WWII is your model, doing a Google by "D Day" and "invasion of France" has just got me around 5,000 hits.

    For a party that makes a big deal out of not being "politically correct," our R'pubs do seem to have a problem saying this word all of a sudden. Iraq's another sovereign state. We may have all sorts of legitimate reasons for doing it, or not, but sending troops into another state to depose that state's government is being called an "invasion" by sympathetic sources like The Japan Times and unsymathetic ones like This Singapore newspaper.

    Lord, how Orwellian we're becoming. "Liberate" is okay, but "invasion" isn't? Can I say "war" or do I need to say "police action" -- because we're supposedly enforcing the resolutions of the body that was so divided over whether we should do this? C'mon, give me some guidance here -- I'm not sure how to adhere to the party line. Re-educate us, comrade.

    With a 2-month lifespan, the power packs would hardly "litter the battlefield", and besides the military is already very conscious of the necessity of not leaving behind anything that can be used as a weapon. When I was in the army, I found it quite amusing that the LAW rocket was designed to be a "disposable one-shot" design, but then they cautioned us that we were to never leave even so little as a fiberglass tube (e.g. LAW rocket launcher) behind, lest the enemy convert it into a mortar or something.
