GM’s future bio-sedans?

GM’s domestic market with E85 FFVs has been limited to the big boys: trucks and SUVs. But they’ve been “dabbling” if you will with what may be their next generation. Saab sedans.

And the Winner is: Ethanol power

The European Shell Eco-marathon for 2006 came to a close a couple months ago. Taking top place in distance travelled for energy used was an ethanol powered vehicle, beating out the Hydrogen ones. It also beat them out in terms of GHG emissions.

And nobody but nobody can rightly claim the Hydrogen powered vehicles were just immature or inefficient:

“While most hydrogen engines use around 95% of their fuel efficiently, the Danish engineers have developed new technology, which allows 100% of theydrogen to be used in the fuel cell. “

The top 5 played outwith Ethanol in first and fifth, with Hydrogen filling the gap.

Clearly there is nothing inherently inefficient about Ethanol. Especially compared to gasoline.

Another Problem with “Global Warming”

In his recent article Seth makes the assertion that Global Warming suffers bad PR due to choices about it’s name as well as it’s lack of immediate impact. I suggest it has an even larger set of problems.

Can Widespread Broadband Save Local Governments Money, and the Environment to Boot?

It is an interesting question. And many of you are wondering what pipe I’ve partaken of in asking it. How can broadband save the environment and money? I ran across an older Real Estate related article on the demand for broadband broken up by categories of use. And I mean an old one, 2002 I believe it was. In it there was an assertion that 17% of broadband demand was for telework – working from home. See, there are the light bulbs.

Let us just run a few quick, back of the envelope calculations. Assume that 15 of that 17% could/would work from home at least 75% of the time. That would mean that using March of 2005’s daily gasoline usage in the US (yes I know about Diesel, but they are fewer. Yes I also know about E85 – much more so than many reading this!) of about 320,500,000 gal/day we could use 24,037,500 less gallons, about 7.5% (assuming I did that right 😉 ). Figuring 20 gallons of oil is roughly a barrel (bbl) of oil, that would be a direct reduction of about 1.2 Million bbl/day (again all general BOTE). We import about 10Mbbl/day. Not too shabby.

To put that into perspective, that is roughly half of our Persian Gulf imports.[1]
