What Are We Doing Wrong with Biofuels?

My friend sent me this article on how biofuels are responsible for a 75% increase in world food prices.

My response: This is what happens when you live in denial for 100 years, and establish an infrastructure around a fuel source that doesn't really "exist" (the sun is the only "real" energy source we have, but that's another discussion). When it starts to run out, everything destabilizes, which is what we are seeing. The obvious choice, which is not always the best choice, is to look for the most accessible, drop-in renewable alternative .

What are doing wrong with biofuels?

1. We're making the wrong fuels.

Ethanol has been the biofuel of choice by many, which is a ridiculous fuel. It takes a lot of energy to distill it, and the resulting fuel has a miserable energy density. There are far better ways to get fuel from plants, unfortunately most are not usable by gasoline cars (see #3)

2. We're making them in a reactive and irresponsible way.
Since we haven't built up an infrastructure that produces biofuels in a responsible and distributive way, the only alternative is to utilize the same resources that have been devoted to producing food. The government is now throwing tons of money at farmers to produce ethanol. If anything, it's easier for them because there are fewer regulations.

3. We're using them incorrectly.
Cars that carry their own power plants (gas/diesel engines) are only about 7% efficient. "Real" energy sources can't be held responsible for producing the amount of energy we traditionally waste. We need electric cars and trucks. Electric vehicles leave the energy conversion process to centralized power plants, where it makes sense to invest the money to make very efficient processing. Furthermore, a wide variety of energy sources can be brought into play, and even mixed, at a powerplant (solar, hydro, petroleum, wind, etc.). This gives you a more flexible infrastructure, so we can be opportunists as different energy sources rise and fall in their availability.

Timbaland rips off a Demoscene artist

I knew this day would come. The new Timbaland/Nelly Furtado song "Do It" uses a song made in 2000 by Finnish demoscene artist "Tempest" (Janne Suni). It's a 4 channel .mod (the ripoff is from a playback using the C64 SID soundchip). The song was hosted on scene.org's servers (the main repository for all everyones demos and tracked music, etc.). As you might expect, no permission or royalties were paid to Tempest. Just to clarify, we're not talking about some kind of coincidence here. There is no question that this track was used to create the song "Do It". In an interview, Timbaland tries to downplay it, saying things like "he sampled it from a video game". (This track was not written for a video game- it was actually written for the 2000 demoscene music competition, in which it won 1st place). Regardless, he basically claims he has no legal obligations because it's just like all the other pop artists that sample other m

Reaper, Linux, and the Behringer X-Air - Complete Studio Solution, Part 1

Introduction and Rationale This is part one of a major effort to document my experiences with recreating my home studio, entirely using Linux.  Without getting into too many of the specifics, a few months ago I decided that I was unhappy with Windows' shenanigans - to the point that I was ready to make a serious attempt to leave it behind.  For most in this situation, the obvious choice is to switch to Mac OS.  With its proven track record, support, and options for multimedia production, it is naturally the first alternative to consider if your goal is to simply use something other than Windows. For me the choice was not so simple. I despise Mac OS and, in general, the goals and philosophies put forth by Apple in an effort to ostensibly provide users with an "easy" working environment.  It does not help that I have also failed to find any aspect of the Mac OS UI intuitive, but I realize that this is a subjective matter. With my IT background and user-control* favori

Windows 8 audio clicks and glitches narrowed down to Malwarebytes

Ever since I got my Windows 8 PC, I have been having serious problems with audio.  Basically all sound playback on my system experiences a brief  but frequent click, skip, glitch, stutter, whatever you prefer.  I can reproduce the issue on any sound card or firewire sound interface (devices tested include the onboard Conexant SmartAudio HD, my external Phonic Helix 12, and my Edirol FA-101).  All of them seem to have audio clicks, with the firewire interfaces' clicks seeming more harsh for whatever reason.
