Entropy

Last week I had a unique experience.


I commute quite a bit, I commute a lot. I use my laptop, I use it a lot. I think you can see where this is going.


I tried to go two days on a three hour battery. It made me realize how little I can get done without this hunk of metal in front of me. I felt lost, not because my files were gone or because I needed to get to my email -- I've already learned that lesson. Instead, it was interesting to consider the relationship I now have with this machine and on a larger scale how society has organized itself around technology.


We as a species have made a pact with electricity that cannot be undone. I know this has been said before but it's worth repeating. It all comes down to energy.


Here's a thought: there are no renewable energy sources. The term itself is a misnomer. Laws of thermodynamics and such. Instead, there are only those resources so plentiful that their responsible management offers a higher degree of sustainability.

Man Creates Homemade Biodiesel from Algae


More proof that the auto industry is dragging its feet. I haven't read much about the energy efficiency involved in the production of Biodiesel, but something about it just makes sense. Single cell organism reproduce rapidly and usually require a single source of sustainance...like the Sun. Still, transportation becomes a problem and for that reason electricity might still be the way to go.

Or something like that.
