- Transparency means nothing without justice – Government transparency is necessary, but not sufficient. If police violence is recorded and publicized, and nobody cares, it doesn't matter. This is in come sense emblematic of the coup in western propaganda. You don't need to control the media as the Soviets did or the Chinese do, if your population is comfortable enough not to care what's happening out there to someone else, and if their voting patterns are firmly tied to other issues (especially social issues like abortion), the idea of a democratic revolt becomes fairly abstract. I think this where a lot of the government's fear of economic recessions comes from. When people are out of work, or even hungry, suddenly they become a lot more excitable.

- Condensing steam without water – Concentrating solar thermal power stations are ultimately designed to run a steam turbine, just like a gas-fired power plant. That means they need water (to turn into steam). Problematically, most such plants use water as a condensing coolant (70% of Caltech's water usage is as coolant for our 14MW worth of gas-fired power)… which is going to be hard to come by in the desert, where CSP will be built. Thankfully, there's a way to recondense steam without using a water coolant – but it does require a huge cooling tower. Not so great in Pasadena, but probably fine in the Mojave, next to acres and acres of mirrors. (tagged: solar energy technology sustainability green electricity water )
- Rousing a Latent Defense Mechanism to Fight HIV – It turns out there is a gene in humans that produces a protein which inhibits infection by HIV, but it has a mutation – a premature stop codon – which prevents it from being effectively synthesized. This mutation doesn't exist in most Old World monkeys (and that's apparently why they can't get HIV). Undoing the mutation allows the protein to be synthesized, and grants HIV immunity to human cells. I imagine that undoing bad mutations like this, and our inability to synthesize vitamin C, might be the first place we see human germ-line engineering outside of disease avoidance (preventing e.g. cystic fibrosis). Really, these mutations are hard to distinguish from genetic diseases – they're just diseases that we, as a species, have learned to live with.

- Twitter + Stimulus = Humans are Gullible – A wonderful demonstration of the power of the confirmatory bias. Twitter is the perfect platform for the injection of random falsehoods. Too short for citations. Instantaneous distribution. Make sure your followers are predisposed to agree with what you say, and you can get them to believe just about anything – within that constraint. Too bad the author seems to think this only applies to conservatives. (tagged: politics twitter statistics propaganda )

Microwire Photovoltaics at Caltech
I went to this year’s second Everhart Lecture yesterday by Josh Spurgeon, who is working with Harry Atwater and Nate Lewis, trying to develop cheap, scalable solar cells. As with most of the Everhart Lectures, it was a very well presented talk. Unlike many of them, it was directly relevant to a real-world problem: how can humanity continue to utilize on the order of 10TW of power, without changing the composition of the atmosphere (see Nate Lewis’ excellent presentation for more information). The ultimate solution to that problem will almost certainly involve directly capturing incident solar energy, because the potential resource available is both vast and relatively concentrated, when compared to other sources of renewable energy. But solar has two very serious problems today: it is expensive (both in absolute terms on a per watt installed basis, and in an up-front capital expenditure sense), and it is not available when the sun isn’t shining. Whatever the solution looks like, in order to scale up to 10TW, it needs to use only earth-abundant, non-toxic materials. In semiconductor photovoltaics then, silicon probably has an unassailable lead. It’s the second most abundant element in the Earth’s crust, and it’s about as toxic as sand (though silicon semiconductor fabrication has serious toxicity associated with it and certainly needs to be made closed-loop). Exotic materials like cadmium-telluride, and copper-indium-gallium-selenide (CIGS) are unlikely to scale to tens of terawatts, simply because of the limited availability of elements like indium and tellurium. Additionally, owing to the vast silicon microprocessor industry, we are much better at micro and nano-scale manipulation of silicon than any other material on Earth (ignoring for the moment biological systems).

Have you seen the light?
As animals, and especially visual animals at that, we have a particular experience of the light. For us it is illumination, information about our surroundings. For that purpose moonlight or even starlight will do. And for tens of millions of years, that’s all we ever saw. Somehow a few of us made it through the Permian extinction, and into the Triassic, but the ascendancy of the dinosaurs eventually forced us into the darkness of the night. Our world became dim, and our eyes went colorblind. Most mammals today see only two colors, but a few of us have re-evolved a third photoreceptor. Three colors is still inferior to the four or five or six seen by many near-surface fish, birds, reptiles, insects, and other arthropods. The stomatopods are almost biological spectroscopic imaging systems, with 12 color channels in each of their independently movable trinocular eyes. We are lesser than the eyes that never left the light. They stole the colors from us and made us hide within the night. They kept the sun for themselves, not knowing that our small and furtive ways, our burning endothermy and our fur would see us through the aftermath of the KT impact.

- Hussman Funds – Weekly Market Comment: Buckle Up – I don't see any reason to trust Hussman more than the normal investing talking heads who do about as well as chance would predict, but he can do division:
The course of defending the bondholders of insolvent institutions is not sustainable. Do the math. The collateral behind private market debt is being marked down by easily 20-30%. That debt represents about 3.5 times GDP. That implies collateral losses on the order of 70-100% of GDP, which itself is $14 trillion. Unless Congress is actually willing to commit that amount of public funds to defend the bondholders of mismanaged financials so they can avoid any loss, this crisis simply cannot be addressed through bailouts. Bondholders have to take losses. Debt has to be restructured. There is no other option — but the markets are going to suffer interminably until our leaders figure that out.

- Thefts puncture Paris bike scheme – More of Paris' Velib bicycles are being stolen or vandalized than expected. Not sure what their expectations were, but it is pretty annoying for basically every bike in the network to have been either stolen or damaged in only 18 months. The vandalism is probably impossible to stop (since it can be carried out while the bikes are locked in their stands) but the theft should be preventable with secure stands, and aggressive enforcement of responsibility for a bike while you've got it checked out (i.e. if the bike doesn't come back, your credit card is immediately charged for the total value of the bike, or possibly even more). I also can't help but wonder if the same functionality could be implemented with much, much cheaper bikes, especially in a city as flat as Paris. Singlespeeds with fenders and a basket, maybe 100 Euros each? With an RFID tag embedded – and put all the smarts in the racks. (tagged: bicycle bike cycling transportation paris velib )

I think it's worth noting also though, that the diversity of pornography on the web has steadily increased over time, and there's a lot of positive and realistic, and non-exploitive depiction of sex out there now, if you want to look for it. In particular Abby Winters, Beautiful Agony, and I Shot Myself come to mind. It's ironic (absurd?) that the site has an "18+ only" clickthrough on the front page.

- Dept. of Energy to draft energy efficiency rules… 30 years late. – I can't believe I'd never heard of this. Apparently for the last 30 years, presidents have been refusing to direct the Dept. of Energy to draft enforceable energy efficiency regulations, despite being directed under law to do so by Congress. Finally in 2005, 14 states sued, and won, and Bush still failed to comply in a timely manner. How many other instances of the executive branch (both democrat and republican!) completely ignoring Congress on important issues are there? It's rare enough that Congress gets anything right – that the president should ignore them when they do is unconscionable!
