A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the engineers who discovered it and proved that it works. The process, called 'photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

With all due respect to Charles Dickens, it appears to be the worst of times for public and higher education in America, if not democracy itself; public schools are increasingly viewed as a business and are prized above all for customer satisfaction and efficiency, while largely judged through the narrow lens of empirical accountability measures. When not functioning as an adjunct of corporate value or a potentially lucrative for-profit investment, public schools are reduced to containment centers, holding institutions designed to largely punish young people marginalized by race and class.

About twenty years ago, Professor Nicholas Ashford of MIT came to Washington and testified before Congress in great detail about how and where safety regulations create jobs and make the economy more efficient in avoiding the costs of preventable injuries and disease.

How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

I've written before about the crisis of inequality in the United States and about the quasi-religious abhorrence of "wealth redistribution" that causes many Americans to oppose tax increases, even on the ultra rich. The conviction that taxation is intrinsically evil has achieved a sadomasochistic fervor in conservative circles-producing the Tea Party, their Republican zombies, and increasingly terrifying failures of governance. Happily, not all billionaires are content to hoard their money in silence. Earlier this week, Warren Buffett published an op-ed in the New York Times in which he criticized our current approach to raising revenue. As he has lamented many times before, he is taxed at a lower rate than his secretary is. Many conservatives pretend not to find this embarrassing. Conservatives view taxation as a species of theft-and to raise taxes, on anyone for any reason, is simply to steal more. Conservatives also believe that people become rich by creating value for others. Once rich, they cannot help but create more value by investing their wealth and spawning new jobs in the process. We should not punish our best and brightest for their success, and stealing their money is a form of punishment. Of course, this is just an economic cartoon. We don't have perfectly efficient markets, and many wealthy people don't create much in the way of value for others. In fact, as our recent financial crisis has shown, it is possible for a few people to become extraordinarily rich by wrecking the global economy. Nevertheless, the basic argument often holds: Many people have amassed fortunes because they (or their parent's, parent's, parents) created value. Steve Jobs resurrected Apple Computer and has since produced one gorgeous product after another. It isn't an accident that millions of us are happy to give him our money. But even in the ideal case, where obvious value has been created, how much wealth can one person be allowed to keep? A trillion doll

September 13, 2011 - Many regulations that were originally scorned by politicians and industry as signaling the death of product lines, companies, and jobs - including those requiring more efficient light bulbs and banning chemicals that damage the ozone layer - in fact stimulated healthy innovations that have protected American lives and saved billions of dollars without harming industry, according to a report by Public Citizen. "Regulation: An Unsung Hero in American Innovation," describes five regulations that were originally excoriated but have resulted in innovations that improved public safety, helped the environment and led to better products. The report comes as public protections are under attack from the U.S. Chamber of Commerce and big business allies in Congress, who focus on the cost of rules while ignoring their public safety benefits and their potential to spur innovations.
