  • A single-issue movement won’t cut it

    David Roberts has been writing about environmental talking points. But I think that skips a step. We need to examine what kind of politics the talking points are intended to contribute to.

    I don't think I have to persuade anyone reading this blog to forget about informed, competent insiders trying persuasion from the inside. Romm tried that with both government and business since the early '90s. Al Gore spent decades as a Senator and Vice President of the U.S. playing insider baseball on the issue. Amory Lovins has been pursuing the "appeal to rational business self-interest" strategy since 1976!

    The only thing will make change is a bunch of ordinary people getting together and exercising their democratic rights as citizens. And it is not just us dirty hippies saying that. Non-hippie former VP Al Gore says:

  • Biofuel processing? Part 2: methanol

    As a method of processing biomass into liquid fuel, methanol tends to be less discussed than its more glamorous cousin ethanol. But it is much more efficient, and can accept just about any biological input besides.

  • Catch up post: replying to some comments

    As promised, this is a catch-up post, wherein I belatedly reply to various comments.

  • An old-school method for making gas from biomass

    There is a great deal of argument over biofuels, and indeed we don't want to overuse them. But I don't think anyone argues that we can't get some of our power from biomass, or that we won't need a sustainable source of hydrocarbons for chemicals and liquid or gaseous fuels.

    I'm going to ignore the usual suspects for a moment to discuss the Fischer-Tropsch process, which uses catalysts to convert biomass to gasoline, diesel, or kerosene (pretty much in whatever ratios you wish). Unlike biodiesel and ethanol, these products are 100% compatible with existing engines in all temperatures, without needing dilution by fossil fuels and without needed engine modifications, even minor ones. The net energy balance is better than for cellulosic ethanol, too.
