I decided to stop posting backlinks in Wiki sandboxes, the SEO strategy previously explained.
[...] In the meantime I'm asking developers and those hosting Wikis of their own to please exclude sandboxes from search engine results (via the robots.txt file). Doing so would shield the sandbox from backlink-postings, and there is no need for it to turn up in search results in the first place.
This sure makes sense, and who knows, maybe future wiki distributions do it by default. (If
Something I read in Science the other day: There's a new proof in review that there are infintely many sequences such as 199, 409, 619, 829, 1039, 1249, 1459, 1669, 1879, 2089 -- primes that differ by a constant offset. See also Mathworld.

Movement to pure hydrogen energy will only happen when a methods for producing free hydrogen don't require more energy than the use of the hydrogen itself produces. It requires energy to make that hydrogen folks. Hopefully all of you proclaimed physicists realize that.
No. If you put in less energy in the production of hydrogen than what the use of hydrogen produces, you're effectively creating energy, and thus violating physics.
Hydrogen tanks will be like a more efficient battery. And as someone pointed out earlier, much more solar energy hits the earth than what we consume from all energy sources. So some overhead is certainly not too relevant.
Well, they've been sitting there since Friday and will spent the next two sols (Martian days) looking at the crater. Here's an amazing hi-res TIF. If you ask me, it looks to steep to go down. But on the other hand, this is the most exciting target in the Meridiani plains...
