Submission + - Harvard professor writes post admitting he was wrong about solar power (electrek.co)

Socguy writes: The Keith group has posted an expert analysis basically saying that their 2008 and 2011 projections were wrong. In those papers the group projected that the cost of solar had a 50% chance to drop to $0.03/W by 2030. In the most recent analysis they note that the current unsubsidized cost of PV in optimal locations is $0.04/W and could easily be $0.02/W by 2020 making solar the cheapest source of electricity on the planet. http://www.keith.seas.harvard....

Submission + - Lithium-ion batteries that last a lifetime (computerworld.com)

Socguy writes: A typical Lithium-ion battery breaks down badly between 5000-7000 cycles. Researchers at the University of California may have discovered a simple way to build a Lithium battery that can withstand 100,000+ cycles.

This was a serendipitous discovery as the researcher was playing around with the battery and coated it in a thin gel layer. The researchers believe the gel plasticizes the metal oxide in the battery and gives it flexibility, preventing cracking.

I get what you're saying but respectfully I would argue that the criteria for determining what you really believe is not all that hard to define.

If someone really believes something then it should have an impact on how they behave in the world. If folks who say they believe in something don't actually do anything that such a belief might lead them to do, even something as simple as showing up a building to discuss their faith on a semi regular basis, then we have no evidence that such a belief is real, yet we have ample evidence to suggest that they don't actually believe.

Comment Re:Supreme Court has already ruled on this (Score 1) 527

I would assume that it's correct that the freedom to believe whatever you want has been ruled on and should be enshrined in the constitution. When/if this goes to the supreme court, the question will be weather or not people actually believe in the tenets of something clearly intended as satire.

Maybe they will find an earnest believer or two, but if they do, how are the rest of the 'practitioners' going to react when they realize that they're promoting what has become a real religion?

Satire is not religion. Pastafarianism is satire not religion. Of course, if this bothers you, you could make it a religion by devoting your life and finances to earnestly spreading/practicing Pastafarianism.

This ruling has nothing to do with making a 'state' religion, it's just pointing out the obvious difference between satire and it's subject.

As a side note: If you don't understand what religion is for its practitioners, then you shouldn't be making fun if it as all you're really doing is making fun of somebody for something that you haven't taken the time to understand yourself.

Submission + - Solar panel developed that can generate electricty from rain. (sciencenewsjournal.com) 1

Socguy writes: Scientists in China have developed a prototype solar panel with a single atom thick layer of graphene on the surface. This layer allows the panel to generate electricity, not just from the sun but also from any rain that falls on it. This development promises to further boost the output of solar panels during times of less than optimal conditions.

Comment Re:So what? (Score 2) 164

No, a flaw was identified in 2012 that ALREADY forced 1 plant into an emergency situation and is also present in nearly all other nuclear reactors. This flaw HAS NOT been fixed, nor does the regulator have any interest in getting it fixed. The engineering group is now petitioning the NRC to force all plant operators to fix it or face closure. THAT is the story here.
