    Oil production has been plateauing despite more drilling in even more remote areas and deeper waters, with new methods of extraction being deployed (shale fracking - it's not just for gas y'know). We keep drilling more holes just to keep up with the diminishing returns.

    The quality of the crude has declined, and it's gotten so bad in the past few years that now tar sands are economically viable because there's no place else to get it.

    Or did you think "peak oil" means it would all run out in one night?

    You can get the equivalent to variable compression ratio by altering valve timing; delaying the closing of the intake valve lowers compression ratio.

    The graph from the article really tells you nothing of value. Compare it to the output of a traditional rotary generator and it's actually kinda crap - looks about a 30% duty cycle.

    Certainly there is nothing you can glean from that graph about the thermodynamic performance of the engine.

    Plus, you are not getting a motion that is significantly different than sinusoidal with what is a fairly normal spring-mass-damper system. On the other hand, mechanically driven engines can have all sorts of fun motions with relatively simple modifications: The Prius, for example, uses modified valve timing to achieve an Atkinson-cycle-like profile.

    If anything, you can compare it to the thermodynamic efficiency of a fuel injected 2-stroke... because that's exactly what it is. In that case, it's slightly more efficient by virtue of less mechanical loss.

    The real advantage is lower part count, which cuts weight, size and cost. Couple this with a narrowly defined power band to optimize efficiency and you have something worth pursuing. If you want to increase efficiency further, maybe replace the lossy gas spring with a second combustion cylinder to get some of that bang back for your buck.

    Where does the law creating the FTC give them the power to regulate this? Please show me the wording.

    15 U.S. Code 45 states "The Commission is hereby empowered and directed to prevent persons, partnerships, or corporations [...] from using unfair methods of competition in or affecting commerce and unfair or deceptive acts or practices in or affecting commerce. "

    15 U.S. Code 46 gives the FTC further authority to perform investigations and classify businesses for the purpose to regulating them. They also have the authority to compel corporations to file reports for various reasons.

    15 U.S. Code 57a gives the FTC authority to deal with unfair business practices by creating rules.

    15 U.S. Code 57b gives the FTC legal teeth if the rules they prescribe are not followed.

    So the FTC has the power to investigate "dealership laws," determine if corporations are exploiting these laws in an unfair way, and act if they see fit. The FTC and the Interstate Commerce Clause meet at the Sherman and Clayton antitrust acts, which the FTC was essentially created to enforce and was given broad judicial, legislative, and executive powers to do so without requiring congressional action.

    Now, that's not to say that Congress CAN'T step in - only that the FTC does not need their permission. Note that rules and regulations that the FTC is empowered to create and enforce are not the same as laws - Congress is still required to make new laws.

    The law that allows the FTC to take action on the matter is the fact that they exist.

    Congress does not have to address it, because Congress created the FTC to address things like this a century ago. Congress doesn't need to delegate anything because this is explicitly within the FTC's jurisdiction already. It also doesn't matter that the founding law doesn't mention specific products and services - the role of the FTC is to protect consumers.

    Keep in mind that there has been nothing official from the FTC yet, but they have the power to step in and try (perhaps not successfully) to regulate, alter or annul even state-level laws that they feel are to the detriment of consumers. That is precisely the reason they exist.

    And since you mentioned them, the FTC has also bumped heads with the AMA back in the 1970s for somewhat similar reasons. The AMA lost.

    1. There are valve assemblies on "top" of each piston assembly, and these valves are flipped back and forth by the motion of the pistons themselves.

    2. The tubes are only a few inches long between valve and piston, and the valve itself vents the "off" side. At most you only need to depressurize a few inches of tubing at a time.

    3. There appears to be four pistons per assembly, 16 assemblies per stack, and 4 stacks. Each piston assembly has a small crankshaft which outputs to a gear, and then each assembly in the stack combines their power via a set of gears to a shaft, and each stack contributes to the shaft. You don't have (or need) a single central crankshaft like with a typical car engine.

    4. It doesn't necessarily need bearings, but it's entirely possible to make select sections that are round enough or use a series of wheels that ride in a round-enough track for support. Alternatively, the gearboxes on either end could be non-LEGO, leaving only the shaft to be built with no support required. (I suspect this is the case at least for the rear axle)

    So it seems rather ignorant for anyone to make claim to "2nd Amendment Solutions" as they are sometimes called, because in a strict interpretation of the US Constitution a "2nd Amendment Solution" as these people envision it would be to just shoot themselves.

    The real reason for the 2nd, IMHO, is because the US is not supposed to have a professional army. That's also in the constitution: "To raise and support armies, but no appropriation of money to that use shall be for a longer term than two years." Instead, private citizens were explicitly allowed to keep firearms so that in the event of invasion or insurrection, we would have a ready force to deal with it until a formal army could be put together instead of having to support an army in perpetuity.

    I get the feeling that you naively believe that an insurance company, offering different plans to different risk pools, is somehow keeping each plan's/group's finances completely separate. And it is absolutely not the case that you have some kind of account dedicated only to you, that only your money flows through, like a savings account that you can draw from when the conditions of the insurance contract are met. (I don't think you are THAT naive... but the part you put in quotes makes this worth mentioning.)

    Just because you buy plan A and I buy plan B, does not mean that my money will never go to you and your money will never go to me. It just means that we pay different premiums based on our risk.

    From the standpoint of the insurance company, the goal of course is to make profit. That means you WANT healthy people to pay into the system explicitly so their contributions can offset the costs of the sick people making claims against their policies.

    What you describe is already in place fro the poor and elderly; Medicare and Medicaid, respectively. They've been around a long time and they're pretty popular with everyone. There's also social security, which is essentially the same except not medically related.

    I think everyone who understand what insurance actually is understands - at least implicitly - that they are subsidizing someone else. These people also understand that if they end up needing help, then others will be subsidizing them.

    It real fun is when those who don't understand this end up relying on that insurance themselves and feeling just as entitled about it as they chide others for supposedly being. No sense of irony.

    When it comes to healthcare and the mandate, though, you are replacing an indirect subsidy with a quite possibly cheaper direct subsidy. Indirect, because these uninsured people still cost YOU money when they get sick one way or another... usually in the form of higher costs for healthcare because the uninsured either resort to hospital emergency rooms and the expenses they can't pay end up being covered by those who can pay, or by unspecified economic costs from lost productivity or opportunity (i.e. bankruptcy from medical bills, inability to work due to illness, etc)
