Solar Breakthrough: Cheap Quantum Dot Solar Paint

Researchers have reduced the preparation time of quantum dot solar cells to less than an hour by changing the form to a one-coat quantum dot solar paint.

How?

Titanium dioxide (TiO2) nanoparticles are coated with cadmium sulfide (CdS) or cadmium selenide (CdSe.) The composite nanoparticles, when mixed with a solvent, form a paste that can be applied as one-step paint to a transparent conducting material, which creates electricity when exposed to light.

Although the paint form is currently about five times less efficient than the highest recorded efficiency for the multifilm form, the researchers predict that its efficiency can be improved, which could lead to a simple and economically viable way to prepare solar cells.

EUR/USD Testing January 2011 Low (High 1.28s)

EUR/USD Update: After approaching the 1.28738 January 2011 support level on 12/18, EUR/USD just about hit that level tonight. EUR/USD broke 1.29 and hit a low of 1.28877 before bouncing to 1.29200. You can see that EUR/USD is still in a steep downtrend, as it has been since Oct (or really May). BUT, if the Euro can base out here and rip through that trend line, it could re-test the 10/4 low 1.31460, like it tried a few days ago before bear flagging around trend resistance and breaking down. It could then rally on up to that next downtrend line that hits around 1.36-1.38 in early 2012. It depends on the eurozone sovereign debt catalyst, or ECB/Fed actions if positive for the euro. If not, bye bye to 1.25-1.18. In another post I'm going to embed videos with analysts and a hedge fund manager that believe the Euro is going lower, or possibly to parity.

Japanese Tsunami Filmed By Driver In Floating Car (Craziest Moment of 2011)

As 2011 comes to a close, I have to say the Japanese tsunami was the craziest thing to happen this year. Tom Anderson on G+ just put up a video of a driver filming the Japanese tsunami as it hit his street. His car started floating around.

Satyajit Das Explains How We Got Into This Financial Mess (INET Video)

Satyajit Das (INET)
For those of you who still care about why the financial system collapsed in 2008, which required trillions of dollars by the Treasury and Fed to bail it out. Satyajit Das, an author and derivatives expert, who's been in the business for 34 years, was interviewed by Robert Johnson of INET (Institute for New Economic Thinking) on how we got into this financial mess, and the challenges the global financial system faces going forward.

Margin Call!
Das said it all started in the late 1980s when old-school bankers like himself were replaced by business school trained bankers and derivative traders that religiously relied on models and financial theory to manage risk (see video #1). He also mentioned that profit margins were so great back then that making mistakes (losses) didn't even matter.

In the end, Das said leveraged bets using other peoples money; complex derivatives; mis-priced clustered risk; churning structured products to maintain profitability; repackaging risk throughout the system (counterparty risk); and the incentive to churn for bonuses, ultimately destroyed the financial system in 2008 when risk management failed. Interesting interview (h/t naked capitalism).
