  1. Re:But the engine upgrades are what make it fun... on US Offers $30M For High-Risk Biofuel Research · · Score: 1

    Engine mods and upgrades are NOT fun. The reason is that it often costs upwards of $100,000 to certify any conversion kit for a vehicle with the EPA. What this means is that all alternative fuel mods on post 1975 vehicles are a no-go. Unless the fuel can go in without conversion (like with biodiesel), then the costs are going to be too high to make it viable. This is why CNG is not our primary transportation fuel right now.

    Developed country population growth will not stop without closed borders, which is not politically fashionable. Developing country population growth will not stop without massive increases in wealth, which has real physical limits. Barring epidemics or massive warfare, how do you envision population growth stopping? Because nowhere on Earth is it stopping voluntarily.

    This is the central flaw of Malthusianism. If you look at this graph, you'll see that population growth (births/woman) slows down as you get richer, with some noted exceptions in cases of religion. This means that wealth = no population growth.

    There are clearly limits to wealth. The question is how big they are. History shows us that they are a lot bigger than we think. Here is the question. What would happen if everyone had a US style suburban home. The answer is that the only thing stopping it is energy. This is because our suburbs are powered by fossil fuels, not renewables. If we changed the equation and switched to renewables, 10 billion people could live in suburbia. 10 billion americans = 100 terawatts. The solar influx to the earth = 175,000 terrawatts. The prices of metals are all going down, meaning that they are getting less scarce.

    "Innovation" currently goes almost exclusively into creating new consumer trinkets, healthcare and military applications which destroy wealth, increase lifespan and consumption, and create resource shortages.

    A lot of innovation is going into producing the hated consumer trinkets, but much is going into renewables and finding new reserves of metals.

    So what will you call it when global production peaks?

    A transition from oil to renewable energy. Oil production will peak from traditional sources, because renewable energy prices will crash through the floor, and production will soar.

    What, iron? We have that. It isn't economically viable. And it will never produce enough liquid fuel to provide for the level of transportation we currently enjoy.

    Then why does south africa use it for their diesel? Because it is.

    You realize that coal will peak also, and isn't unlimited?

    Because you can feed waste biomass into the system, like sewage, trash, and wood scrap. This already happening in Africa.

    Population grows exponentially.

    Paul Erlich, Tomas Malthus and the members of the flat earth society still believe this. The problem is that it is false, because captalism = wealth = less population growth. India, China, the USA, all have zero or rapidly zeroing population growth rate.

    "Affluence" will peak once we reach the limit of exploitable resources on Earth.

    Actually it will stop because people are starting to get satisfied with the amount of stuff they have. Once you have a house and an SUV, and maybe a motor home, what else do you want?

    "Technology level" (whatever that means exactly) will peak given a large enough supply-shock to send researchers heading for the hills.

    Because population growth will stop, innovation will stop the shortages, and wealth will grow, this just won't happen.

    You do the math.

    I did the math. Now let's see some math from the Malthus flat earth society, who's basic core fact (exponential population growth) is utterly wrong.

  8. Re:And... on Watch 200 Years of Global Growth In 4 Minutes · · Score: 2

    No it's not. There is for all piratical purposes unlimited amounts of oil in the planet. We're getting to the lower ores, the tars and sluge, basically. Once we're below that, we've got air and water. That's why many, many people are looking to that unlimited oil resource (sky and water and sun), so that won't happen. There has never been a non-localized shortage on earth in history.

    Here's some of the best links in this regard:
    1. The synthesis of gasoline and diesel with nuclear energy (PDF).
    2. The Sandia CR-5 thermochemical engine (PDF).
    3. Windfuels.

    Oil will never run dry, ever. Right now, we throw out waste biomass equivalent to 20% of our oil consumption, and about 50% of our oil consumption. Cut oil use by 50% (even lead-acid plug-in hybrids can achieve this), and we don't need any of the above technologies. We just need the same stuff the South Africans currently use to turn coal into diesel.

    Oh, and I should mention that natural gas, not oil, (really hydrogen) is the primary component of the "oil-based" fertilizers. A lot more of that than oil. In fact, ammonia was originally produced by using hydrogen form water and electricity from hydroelectric powerplants.

    There is a reason why battery technology hasn't developed as fast as the technologies that use them; packing more and more energy into a given volume is a dangerous thing to do.

    Not necessarily. What you want is something that is energy dense yet kinetically stable. Explosives are the opposite. Explosives deliver small amounts of power really fast. For example, the best explosives (according to wiki) are around 16 MJ/L and most around 3-5 MJ/L. Gasoline is at 34 MJ/L. If you want something that stores a lot of energy and won't explode, look no further than a pile of scrap aluminium. Aluminium stores roughly 83 MJ/L. You wouldn't be scared to have a ton of aluminium lying around behind your house, but that block could store enough energy to run your house for a year.
