Fuelishness! Marathon – Part 3: What is cellulosic ethanol; Algae Farming; Most Efficient Way to Travel 350 Miles

  • What is cellulosic ethanol and how does it fit with green cars? : There is a lot of controversy surrounding biofuels. Various studies have shown that crop-based biofuels contribute to global warming more than they help prevent it, that ethanol is no better than gasoline, and that South East Asian rainforests are suffering for biofuels, to name just three. The most dramatic recent claim was that ethanol was the worst type of renewable energy.
      
  • Algae Sizzle and Algae Steak : Bionavitas “Light Rod” idea called Light Immersion Technology that looks like a giant tapered optical fiber that places light at depth into algae cultures. Ingenious as ideas go, with a near stunning amount of coverage on Wednesday the idea might get some financial and research legs. What has been left out is the details about the light. The photos seem to leave out the top of the rod or fiber or just show a shaft, whose top area sets the amount of light; no matter how deep it is distributed. The idea solves a problem in algae culturing, getting light deep so that the culture isn’t just a thin layer at the sunlit surface.
      
  • How Many Gallons of Fuel Does it Take to Travel 350 Miles? : GOOD Magazine, in collaboration with Robert A. Di Leso, Jr., explores fuel use by various modes of transportation. In what is essentially a fancied up bar chart, we see how many gallons of fuel it takes for a passenger to travel 350 miles by cruise ship, Amtrak, Boeing 737, Sedan, hybrid, etc. A couple of non-fuel modes of transportation are included as well using caloric conversions. It’ll take about 48 Whoppers with cheese to walk 350 miles. Good to know, especially since I was planning on walking 350 miles today. Totally kidding. I’m walking 360. Like a circle.

    I enjoyed the bar graph of how many gallons of fuel it takes to go 350 miles by various modes of transportation. I guess if the amount of time to get where you need to be wasn’t as important, we’d all be biking and walking. We diffinitely would be more healthy too.
