Why care about liquid fuel?
There’s a reason we use different forms of energy to do different jobs, and it’s not because we’re all just that fickle. Instead, we’ve made these decisions based on some combination of what has (historically, anyway) given us the best results, what is safest, what is most efficient, and what costs us the least money.
In a nutshell, that’s why liquid fuel is so valuable. So far, it’s the clear winner when we need energy for transportation—especially air transportation and heavy, long-distance shipping—because it allows you to stuff a lot of energy into relatively small amount of storage space, and easily refill on the go. There are other options, of course, like electricity. And that can work quite well, depending on what you’re trying to do. Eventually, we may find ourselves in a world where liquid fuel is no longer the best option. But we aren’t there yet. And for those forms of transport that take us into the air or move our belongings very long distances, we aren't likely to get there for a good long time.
That's why I care about liquid fuel, and why I'm interested in the future of biofuels. Yes, biofuels do have a future. But what that future will be depends on whether we can control for some very messy variables. Here, in three points, are the big things you need to know about biofuel.
1. Corn ethanol really is flawed. But maybe not as much as you think.
Biofuel is a nice, round word encompassing a lot of tricky, little, oddly shaped dots. Read the rest
To get off nuclear power, Germany plans to make its electricity system 80% renewable by 2050. That's not going to be easy. Just to reach the first milestone of that goal—35% renewable capacity by 2020—the country will have to build 2,800 miles of new, high-voltage transmission lines. Although, one significant thing missing from this story: How many miles of transmission lines Germany would have normally built during that time. Even so, watch this space for financing debates, NIMBY wars, and what promises to be some really fascinating problem solving. (Via Michael Noble and thanks to Chris Baker!) Read the rest
It looks like Boeing will be the main competitor for Space X in the race to see what U.S. company will provide the commercial space flight services that NASA eventually plans to rely on.
Space X has its Dragon capsule, and Boeing is developing a new capsule system, called the CST-100. That capsule would ride into space under the power of an Atlas V rocket, an engineering descendant of the Atlas rockets that carried the first four American astronauts to space half a century ago.

“It’s still flying?” This is a question I and many of my fellow space enthusiasts have been hearing a lot lately. As the space shuttle program comes to an end, public excitement around space travel seems to be rekindled. Attention sparked up again as people heard that Space Shuttle Atlantis was preparing to launch for the last time, marking the end of the space shuttle program. But for one young person, that interest had never faded, and witnessing the shuttle's final flight became an imperative, a very personal hope and dream. That person was me.

Don't muck around in the affairs of planets that are less technologically advanced than yours. Despite how often it gets ignored, Star Trek's Prime Directive is a pretty nice attempt to take a universe brimming with life and figure out how to interact with it in an ethical way.
Unfortunately, the Prime Directive isn't terribly nuanced.
How do we relate to alien life that's as, or more, advanced than us? What if alien life is bacteria—do we still have to leave its home planet alone? How do we explore the galaxy without spreading—or picking up—any deadly diseases? The Prime Directive can't really help you here. That's why scientists from NASA and the SETI Institute are boldly going where no bureaucracies (real or fictional) have gone before—drawing up the safety protocols we Earthlings will use as we explore new worlds, and the social and ethical guidelines we'll turn to if we ever do find life on other planets.
