Distribution – why it is so hard to add E15 or E85 at a gas station
Preface. One of the huge hurdles to shifting from oil to “something else” is the chicken-or-egg problem of no one buying a new-fuel vehicle with few places to get it, so few are made, so service stations don’t add the … Continue reading

Book review of Underbug: an obsessive tale of termites and technology
Preface. I read this book mainly to find out where “grassoline” stood. Scientists thought 10 years ago that we could recreate the termite biota system of digesting biomass to create biofuels. But this appears to be far in the future … Continue reading

No, we’re not going to make ethanol out of CO2 and stop global warming
Preface. In the article below Robert Rapier debunks the research paper proposing to convert CO2 into ethanol. The researchers were honest and said “that the process is unlikely to be economically viable.” But the press spun it into a major … Continue reading

Why studies come up with different Energy Returned on Invest (EROI) results: can it be fixed?
[ There are many issues with biofuels beyond their trivial to negative energy return on investment (EROI). In Peak Soil I point out that current industrial farming techniques are destroying topsoil about 15 times faster than pre-fossil fuel economies — … Continue reading

Schlesinger predicts investments in 2006 will cause oil glut and denial of peak oil in future
Energy Security and Oil Dependence. Two Senate hearings from 2006. In these two 2006 hearings (excerpts below), there is a constant refrain of our dependence on oil, yet now, many congressional hearings are about our energy independence. Apparently congress has … Continue reading

GAO on why ethanol, and other non-drop in fuels, face pipeline & installation at service station challenges
[The challenges that ethanol faces in being put into new or modified pipelines and added to gas stations are issues faced by all alternative fuels (methanol, CNG, LNG, DME, diesohol, CTL, hydrogen, and so on) in a transition from gasoline … Continue reading

Large agribusiness gets corporate welfare via illegal ethanol subsidies
What more proof is needed that the Energy Returned on Energy Invested of ethanol is negative? They’re losing money and getting corporate welfare to keep the scam going, meanwhile destroying prime topsoil, poisoning the land with pesticides, and eutrophying the … Continue reading
