Profound Quotes

"Neither is it that US foreign policy is cruel because American leaders are cruel. It's that our leaders are cruel because only those willing to be inordinately cruel and remorseless can hold positions of leadership in the foreign policy establishment; it might as well be written into the job description. People capable of expressing a full human measure of compassion and empathy toward faraway powerless strangers - (let alone American soldiers - do not become president of the United States, or vice president, or secretary of state, or national security adviser or secretary of the treasury. Nor do they want to." From 'Rogue State: A Guide to the World's Only Superpower' by William Blum

From "9-11, Six Years Later": "If one looks at the credentials of skeptics compared to the credentials of defenders of the official line, it is impossible to dismiss skeptics as kooks. There are many people with strong imaginations on the Internet, but serious skeptics stick to known facts, known violations of standard procedures and the laws of physics. The vast majority of the people who call skeptics "kooks" are themselves ignorant of physics and have little comprehension of the improbability that such an attack could succeed without either the complicity or complete failure of government agencies. " Paul Craig Roberts

"Cowardice asks the question, 'Is it safe?' Expediency asks the question, 'Is it politic?' Vanity asks the question, 'Is it popular? But, conscience asks the question, 'Is it right?' And there comes a time when one must take a position that is neither safe, nor politic, nor popular but one must take it because one's conscience tells one that it is right." Martin Luther King, Jr.

Spain plugs in largest solar-tower power plant | Green Tech - CNET News

Abengoa Solar of Spain on Monday reported successful tests of its second solar tower in operation, in which the sun’s heat is used to make electricity.

The 531-foot solar tower, located near Seville, Spain, features a number of improvements on the first design and has exceeded the anticipated output. Called PS20, the installation is the largest in the world with a capacity of 20 megawatts, enough electricity to supply 10,000 homes, according to the company.

A solar tower configuration uses a field of heliostats, or mirrors, to concentrate sunlight onto a receiver held in the tower. The heat creates steam which turns a turbine to make electricity. The PS20 project has 1,255 of these heliostats, with each heliostat having a surface area of 1,291 square feet.

Concentrating solar thermal technology has been used in desert areas in Spain and the southwest U.S. for decades and is seeing a resurgence as utilities seek out cost-effective solar power.
