"Sun Strick: "A March 13, 1989 solar flare knocked out the power grid serving over 6 million customers in Canad, yet was only one-third the size of the Carrington event' of 9/1/1859. A period of maximum solar activity is expected later this year and a National Academy of Sciences report estimates such a storm could bring the disruption of 20 Katrinas and take a decade to recover from.The sun's core is a 27 million degree F plasma six times the density of gold that fuses 700 million tons of protons into helium nuclei every second, releasing the energy of 10 billion H-bombs. Matter is so tightly packed at the core that it takes over 100,000 years for the photons to reach the convection zone located 70% of the way out. Then its another month or more before they begin their journey to Earth, etc.
Scientists can only provide a few days warning of potentially dangerous solar flares. Most power grids have no protection and geomagnetic storms can induce currents causing them to overheat, catch fire, or explode. GPS and radio communications would also be disrupted.
"In China's Shadow:" Hong Kong has the most skyscrapers in the world, along with a population of 7 million, almost half in subsidized housing. It's been 15 years after the British handover and citizens are still relatively free to protest, though not as free as before. Per capita GDP ranks at #10 in the world, but it also has one of the highest degrees of inequality.
Britain had acquired Hong Kong as an outgrowth of the Opium Wars. Its early capitalism was boosted by refugees from Mao's rule in China; in the 1970s much was still rice paddies. Prostitution has been legalized, taking up entire apartment buildings in some locations. Services are advertised on the Internet, providers can earn $100,000/year at the rate of $60/40 minutes. The Rolex store at the city's Times Square sells 200 watches/day, mostly to mainlanders, and its 9 Gucci stores have long lines in front.
