Submission + - Small-scale biomass energy projects are not a solution to climate change (thebulletin.org) 1

Lasrick writes: Roberto Bissio has an excellent piece in a roundtable on biomass energy, pointing out that small scale biomass energy projects designed for people in poor countries aren't really a solution to climate change. After pointing out that patent protections could impede wide-spread adoption, Bissio adds that the people in these countries aren't really contributing to climate change in the first place: 'Why? Because poor people, whose carbon emissions these technologies would reduce, produce very little carbon in the first place. As I mentioned in Round One, the planet's poorest 1 billion people are responsible for only 3 percent of global carbon emissions. The 1.26 billion people whose countries belong to the Organisation for Economic Co-operation and Development account for 42 percent of emissions. The rich, if they reduced their emissions by just 8 percent, could achieve more climate mitigation than the poor could achieve by reducing their emissions to zero. The rich could manage this 8 percent reduction by altering their lifestyles in barely noticeable ways. For the poor, a reduction of 100 percent would imply permanent misery.'

Submission + - Ford, University of Michigan Open Next-Generation EV Battery Research Lab

cartechboy writes: Its no secret that one constraint on electric vehicle adoption is battery production capacity and cost. Right now battery costs add thousands of dollars in price tags on electric vehicles, so the race is on to gain capacity make cheaper batteries. Today, Ford and the University of Michigan are announcing an $8 million EV experimental battery research lab to try and accelerate this type of early testing. The lab, which will be on campus in Ann Arbor, Michigan, will allow automakers, battery makers and individual researchers to test battery cells earlier in the process than ever. The lab says it will have strict controls to protect each entity's individual intellectual property as the research in theory happens all in one place.

Submission + - Stallman: How Much Surveillance Can Democracy Withstand? (wired.com)

Covalent writes: RMS describes how much surveillance is too much (hint: it's all too much) and how to combat / circumvent / prevent future surveillance.

How much of what is suggested is plausible? How much is just a pipe dream? Discuss!

Comment More evidence of similarity (Score 5, Interesting) 57

It seems that nearly every week there is an example of a new solar system with somewhat similar characteristics to our own. We've seen large planets, rocky planets, and now asteroids with high water content.

In 1995 my physics teacher told me we'd never have direct evidence of extrasolar worlds. Now I tell my physics students that I wouldn't be surprised if we found evidence of extrasolar life (probably in the form of a planet with a high concentration of oxygen in its atmosphere).

It's a great time to be alive and to be a scientist!

Comment Re:snow on a dwarf planet (Score 1) 42

Yes, but have we seen it snowING?

Further down someone mentioned Enceladus. That's a pretty good example, but I would argue that's not snow so much as volcanic (geyseric?) fallout. Not really atmospheric precipitation in the general sense.

Titan also appears to have snow and rain, though we haven't really seen it fall (though not for lack of trying).

Interestingly, on all of these worlds the substance being "snowed" is different. Water on Earth, Carbon Dioxide on Mars, Methane on Titan, and potentially Nitrogen on Pluto. I love science.

Comment multiple reasons not to include wireless (Score 2) 115

Security issues aside, wireless connectivity uses some small amount of power. To me this is energy wasting of the highest order. My lightbulbs constantly listening for the one time per month that maybe I want to turn them on from my phone? Yes please and a side of mountain top removal coal mining please!
