Dyson Sphere

Dyson sphere is a hypothetical megastructure originally described by Freeman Dyson. Such a “sphere” would be a system of orbiting solar power satellites meant to completely encompass a star and capture most or all of its energy output. Dyson speculated that such structures would be the logical consequence of the long-term survival and escalating energy needs of a technological civilization, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life.

Since then, other variant designs involving building an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction under the name “Dyson sphere”. These later proposals have not been limited to solar-power stations. Many involve habitation or industrial elements. Most fictional depictions describe a solid shell of matter enclosing a star, which is considered the least plausible variant of the idea (see below). Link

George Dyson – on the possibility of a Google Bank


Although business is substantially more trusted than government, 49 percent of global respondents believe government does not regulate business enough. Nearly one-third want government to protect them from irresponsible business practices and one-quarter want regulation that will ensure responsible corporate behavior. “The interventions people are asking government to take are changes business can step up and implement on its own,” said Mr. Edelman.

Once again, banks and financial services declined in trust, and were the two least trusted sectors with France, Spain, Brazil, Japan, and South Korea recording the most severe drops. Technology remained the most trusted sector globally. Link
