To: average joe who wrote (25090 ) 8/30/2009 9:13:35 PM From: Maurice Winn 1 Recommendation Respond to of 36921 Back in the day [late 1980s] I invented a product called "Jetozone" which was an aerosol designed to increase ozone in the stratosphere as jets roared around the sky. Ozone is no longer a problem because CFCs have been cut way back and the ozone supplies are good enough. Even contrails of jets provide quite a lot of reflection and on the right day over Antwerp and other busy transit areas can cover the sky with fine cloud, increasing reflection greatly and far more than the fuel which is used to produce the cloud. Dew points have to be just right though. In dry conditions, contrails don't last long before the water in the trails is vapourized. There isn't a problem of CO2 to be solved [contrary to popular myth] but if there is, perhaps cloud forming aerosols could be dispersed by jet aircraft as they circle the planet. There are other solutions to CO2 emissions which are never discussed, such as taxing carbon and people migrating to warmer climates so they don't need heating. Burning coal to produce electricity to heat houses which leak air is an expensive way to keep warm. Living in Hawaii is a much cheaper way to stay warm. Not everyone can live in Hawaii, but there are plenty of tropical places where people can live. Even crowded places like India have wide open spaces where millions in cities could swarm. The plains around Bangalore for example could hold 100 million and they'd be not too hot and not too cold being at high altitude. As the world's human population starts falling rapidly after 2037, the CO2 so-called problem will go away. Technology will continue to improve. Much airline travel for example could be replaced by 1000 kph linear motor propelled superconductor levitated and powered vacuum tube cars on autopilot from Shanghai to London, down to South Africa and possibly even under the Bering Sea to North and South America. They would literally fly through the tubes and vastly more safely than 10km high. Around cities too, at slower speeds, the same technology would work well. It's absurd to have dirty great two ton SUVs thundering along freeways at 120 kph with 15 psi of air to be ploughed through when all that's being moved is 70 kg of human protoplasm. Especially with said SUVs being controlled by a variety of monkey with reaction times, attention spans, wakefulness and intelligence akin to chimps. Mqurice
