Comet Lander Sends Photos and Data

I’m sure you’ve been following the news about the rather incredible comet lander, Rosetta, launched 10 years ago by the European Space Agency, which successfully landed on the comet a couple of days ago. Now pictures and data are coming in. If the crafts solar cells are adequately positioned (the craft is in the shadow of a cliff) the craft will operate for months. Most cool. Video from USA Today.

Solar can provide most energy by end of century

I’ve written recently about how solar is getting cheaper and about how it may be growing too fast in the sense that the current energy grid and business systems cannot adjust quickly enough. But an interesting question is whether it would be possible to provide much, perhaps even most energy with solar by the end of the century. I believe this would be a good idea, and perhaps is even inevitable given the declining cost curve of solar, and the likely need to shift toward cleaner energy even if fossil fuels stay relatively abundant deep into the century. Here is an infographic that explores the capacity of solar to fulfill our energy needs that was sent to me yesterday. I think it undersells the challenge of building the energy grid and the storage systems that would make solar this feasible, but you will probably discover some facts you were unaware of as you explore the graphic.
