  1. Re:snake oil, more like on "Vetrolium" From Agricultural Waste · · Score: 2, Insightful

    Energy is like the universal currency whether it takes the form of heat, electricity or the chemical potential energy in an easily stored liquid. You can convert them at various rates of efficiency, and there are financial markets for each type of energy. Given the low efficiency of thermal depolymerization, I suspect it's worth more to use your solar collector to run a steam turbine and sell power to the grid.

    The metric here is Energy Return On Energy Investment (EROEI). Oil is a very concentrated source of energy. In the early days of oil, EROEI was 50-100:1. These days it's still over 10:1 (http://www.theoildrum.com/story/2006/8/2/114144/2387). Thermal depolymerization is nowhere close to that, and it's probably a net negative. Then remember that the feedstock for it is much less energy-dense, and you're moving a huge amount of mass for a small amount of oil. You can mitigate that by locating the plant at a garbage dump where it's already being collected, but there's not enough garbage to replace more than a tiny fraction of our oil use. If you collect virgin feedstock, you're back to the same old problem.

    Bio-crude from thermal depolymerization needs to be refined too. No difference there. The EROEI of refining is typically 10:1, 1 unit of energy (usually natural gas) in for finished product worth 10 units of energy.

    Crude oil is the stored solar energy of millions of years of biomass cooked by the heat of the Earth. The energy we invest is just to drill and pump it out of the ground. The amount of energy needed to cook it out of garbage is much higher.

    Nah, suburban people are more fearful than urban people. "White flight" was all about getting away from the scary brown people. The gated communities and cul-de-sac mazes of the suburbs are all about isolation and escape. Plus, unlike rural people, suburbanites avail themselves of the full array of public safety services like police, fire, ambulance, and sewage (the "city cocoon" as you put it). Suburban people may or may not have an edge in outdoor survival skills, but considering that nobody walks in the suburbs, they probably spend less time outdoors than urban people.

    The problem is that it inherently finds the most efficient equilibrium at any cost. When we reach peak oil--capitalism will re-stabilize the system. But if that means purging mass sections of the population from the equation... that's what it'll do.

    At some point in that collapse, markets break down and the old rules no longer apply. This is the biggest folly of Libertarianism: the idea that markets and contracts reign supreme, that people priced out of the food market will go away meekly and die, and that any violation of that natural order can be ascribed to criminality and solved with law enforcement. Well, I have a newsflash. You can't have commerce without political stability. Starving people will riot for food, and such riots are bad for political stability. Just see the role of bread riots through history.

    The EFF and ACLU have no political influence per se. They're 501(c)(3) charitable organizations just like, say, Focus on the Family, and it's already illegal for them to participate in partisan political campaigning. Here's the IRS pub.

    It gets complicated because it's more than just direct contributions from PACs to individual campaigns. There are various PACS like the ones belonging to Blue Dogs caucus and Majority Leader Steny Hoyer, that collect corporate contributions and distribute to House members.
    The Blue Dogs are a group of about 30 fiscally conservative Democrats in the House. They're reliably in the pocket of corporate lobbyists, so right off the bat, the Democrats were 30 votes behind on stopping immunity.

    The lobbyists have an easier job flipping the Democrats on these votes. The Republicans generally vote as a block because they're all AT&T's bitch (except for Ron Paul who still cares about the 4th Amendment). With the House majority, they only needed to flip 1/3 of the Democrats to win the vote, and that's about how it ended up. 2/3 of the House Democrats voted against it.

    If people were "fine" with it, why would the admin. be trying to keep their violations of NSLs secret? And be trying to grant retroactive immunity to the Telecoms?

    There's "fine with it" and then there's "fine with it". Opinion polls about warrantless wiretapping run about 50-something percent against/40-something percent for. That's a solid majority, but far from the overwhelming majority it takes for Washington to pay attention. That's not even a big enough majority to break a Senate filibuster. The secrecy surrounding NSL and the push for telecom immunity is just to be double-extra sure they get away with it.
