Ethanol Returns
by Andrew McCaskey
The Illinois startup company, backed by General Motors that claims to have the secret sauce to break cellulosic ethanol to sell at $1 per gallon sounds at best, too good to be true.
The article linked in tonight’s show notes speaks of the ability to turn any organic material into ethanol, with a focus upon corn (the non-grain components) and various forms of cellulose.
I think some skepticism is in order. One of the details released is that, before the magic bacteria go to work, the cellulose material is gasified. How that exactly happens – without the addition of energy in the form of heat – is left as an exercise for the reader. Last that I know of, generation of heat by combustion of almost anything is going to produce carbon dioxide as some of the more pleasant by products. While the bacteria are happily munching away producing ethanol, what’s keeping them warm ?
Just the sort of question that you might want to ask on a January night in the Midwest.
I want to believe, but many have unsuccessfully pursued the free lunch, and this story has that aroma.
I recommend this book (and the free Nozbe implementation) because it has been an incredible help to me managing the demands of a daily podcast, travel, day job, and home responsibilities. Please give it a try – I think that you will find that after 30 days, you will be more productive, feel more in control, and better able to manage your day to day tasks.
