    About 65-70% in practice, actually, on a per-gallon basis with E85. So yes, there's a rather modest cost in convenience (or you just have to build cars with 19 gallon tanks instead of 15 gallon tanks).

    But all of this is irrelevant. The fuel:air ratio in modern car engines is an electronically controlled parameter. FFV engines already exist, and cost only a modicum more than standard gasoline engines. They detect ethanol/gasoline mixtures and automatically adjust the combustion ratio appropriately. See the Wikipedia article for a summary.

    Since the vast majority of engines in passenger vehicles and fueling stations currently support gasoline, telling people to get an FFV for their new car is actually much easier than telling them to get a diesel. And in fact, some people already have FFV cars and don't even know it (the car manufacturers sell them to comply with legislation and get tax breaks, even when people don't know their car can use ethanol).

    Nobody except corn farmers has ever proposed using corn ethanol as a fuel on a meaningful scale. That is just a farming subsidy scam and a straw man used by confused or malevolent opponents of ecologically sound fuels, or those with political agendas in line with the fossil fuel industry.

    Bioethanol is ethanol made from cellulose feedstocks. These should, in practice, be much lower in terms of energy input required than corn or similar crops used for human consumption. The economics of bioethanol produced by SSF (simultaneous sacharination and fermentation) bears almost nothing in common with corn ethanol.

    Furthermore, if you get rid of farm subsidies from the equations, then the market should take care of making sure energy costs are fully reflected in all prices. Carbon impact is another story, but shouldn't be too hard to measure (and probably is closely correlated with the portion of costs attributable to energy use).

    As for biodiesel - I am under the impression that the major costs are associated with the feedstock itself, not with the acid used in processing. From memory, I think that the feedstock cost is responsible for at least 60-70% of the final cost of biodiesel, so I wouldn't expect a 10x reduction in acid costs to save more than a few percent in total cost. Genetically engineered bacteria seem to provide the most reasonable way to make an oil feedstock for bioethanol production efficiently. The reason that some people think biodiesel is cheaper than diesel is that in Europe they get huge tax breaks on biodiesel, so they are comparing apples to oranges.

    Bioethanol is by far the most promising alternative fuel available today, with attractive envrionmental impact and economic characteristics, and only modest incremental cost to make Flexible Fuel Vehicle engines that can burn either ethanol or gasoline. It's too bad there is zero governmental support for this here in the US. We could greatly reduce our foreign oil dependence within 5-10 years with just a bit of political willpower.

    Perhaps I was in a grumpy and curt mood when I posted that, but your attitude is no better. You are both wrong and misleading (in that I never said preferred shares are debt). Perhaps like most VCs, you don't have the patience or requisite brain cells to read more than a 1 page executive summary. Clearly I should have said "like debt" and "like equity" to be more clear. Or maybe you are just intentionally misreading to be argumentative?

    Liquidation preference is a debt-like seniority feature that is a part of most preferred shares. Bank debt is going to be senior to preferreds in a liquidation, of course. And interest on debt is non-deferrable (failure to pay leads to default and all the consequences thereof), unlike preferred dividends. Re: conversion features, most preferreds used by VCs have conversion terms of some sort in them. I guess I had to say all of that to clarify. My original point was of course that VCs want upside and control along with as senior a status in a company's capital structure as they can get.

    Oh, and as you reference yourself, convertible notes are often used for seed stage investments by angels and very early stage VC firms, to avoid attaching a fixed valuation to a firm that's too early to accurately value. Though you are right that handing out debt isn't the primary purpose of a VC firm, I never said it was.

    BTW, I have been an entrepreneur (and raised capital from VCs in three separate rounds) and have done private deals at a hedge fund, though I principally invest in public equities.

    It seems related to a behavioral finance effect calling anchoring, which I believe was part of Kahneman and Tversky's Nobel-winning work. From Wikipedia:

    As a second example, according to Daniel Kahneman if an audience is asked firstly to memorise the last 4 digits of their social security number and then to estimate the number of physicians in New York the correlation between the two numbers is around 0.4--far beyond what would be expected by chance. The simple act of thinking of the first number strongly influences the second, even though there is no logical connection between them.

    Basically, people often don't have any absolute framework for judging what is reasonable in a particular situation, so their mind subconsciously focuses or anchors on the first number they see, even if there is no rational basis or relationship between the number presented and the judgment call being asked for.

    Sorry, but you don't seem to understand what the word "evolution" means, since you start talking about cosmology and galactic formation shortly after introducing the subject of evolution. This is a straw man of creationists.

    As a physicist who has done research in astronomy and astrophysics, I can tell you beyond a reasonable doubt that what you are referring to as "evolution" is actually the grand total sum of scientific knowledge about the historical development of our universe. This comes from scientific work in diverse fields, with entirely separate bodies of evidence and so on.

    The only thing these different fields of knowledge have in common is that they happened in the past and we make inferences about them from present observation. Oh, and that they all happen to contradict a literalist interpretation of the Bible, and thus piss of the same yahoos who reject evolution on that basis, even if they wrap themselves in the cloth of "Intelligent Design".

    Furthermore, the demand for "incontrovertable proof of evolution from start to finish" is absurd and represents a complete lack of understanding of the scientific process. That's just not how science works. Theories are falsifiable, not exhaustively provable. And different theories are supported by more or less evidence. Which is why lumping together entirely disparate areas of knowledge under the heading of an intentionally inflammatory word ('evolution') which are backed by entirely different bodies of evidence is itself incredibly intellectually dishonest.

  14. Re:But he neve said. . . on New Discovery Disproves Quantum Theory? · · Score: 3, Insightful

    You are way off base. Every theory backed by sufficient evidence has to be subsumed in future theories (i.e. they have to explain those results as well). Nobody ever "disproved" Newtonian physics, they just came up with more complete theories that reduce to the old Newtonian physics for most normal, human scales (i.e. quantum mechanics and all that came from it for the very small stuff, and general relativity, for the very big stuff).

    So if you have a new theory that explains otherwise unexplainable results, great, but it better also explain why my toaster over, and my CRT, and my LCD, and my computer, and my car and so forth all work too, or else it's worthless.

    BTW, a huge amount of very useful physics is still done using Newtonian mechanics. To think that physicists "discarded" a useful theory because there were more accurate ones for other domains is foolish. I think most physicists would tell you that quantum mechanics is useful and accurate, but I am sure most will tell you that they don't think it's "right" in the sense of being complete and correct. That's old news. If this guy has something that's more complete and correct in that it explains all the old stuff and some new stuff too, I am certain physicists will embrace it, though it will probably take somewhere between a few years and a decade to convince themselves that it all works out (similar things happened with GR and QM).

    Also, not every new discovery is "revolutionary". Plenty are simply minor modifications to the existing theories to account for new results. That seems plausible here to me. That or this guy is defrauding investors big time. Which seems to still be the most likely explanation.

    I do agree that the incentives for lawyers in civil suits are a big problem in that they promote class action lawsuits and over-the-top rewards. This is fairly easily achievable, we just need the will as a society to pass some appropriate legislation. And perhaps it would be better if lawyers saw their first duty to justice, and their second duty to their clients (to achieve this effectively requires incentives that match obligations - so lawyers would need to be remunerated for pursuing justice, not just representing clients needs - this is done in other countries, where lawyer's fees for criminal cases are generally set by law and lawyers are compensated out of state funds, not private pockets). This is conceivable to achieve, but less likely.

    Unfortunately, the part about laws that are always clear, never conflict with each other and have no unclear "corner cases" is a pipe dream. No society has ever figured out how to do that. The more heterogenous and complex your society is, the more complicated the laws needed to run things are, and that's why the US has a more complicated body of laws than many other countries. I really don't think it's possible to radically simplify, though there is undoubtedly "cruft" in terms of law and jurisprudence.
