Carbon Nanotube Field Electron Emitters Will Get Space Testing
2013-11-19 04:58:39| rfglobalnet News Articles
A pair of carbon nanotube arrays will be flying in space by the end of the year to test technology that could provide more efficient micro-propulsion for future generations of spacecraft. Part of a Cube Satellite (CubeSat) developed by the Air Force Institute of Technology (AFIT), the arrays will support what is expected to be the first-ever space-based testing of carbon nanotubes as electron emitters.

S. Korea to Meet Emitters Before Start of Carbon Trading in 2015
2013-03-05 02:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: South Koreas government plans to meet in May with the nations biggest emitters to provide information about the start of cap and trade in 2015. The government plans to select an exchange for greenhouse- gas emissions in the second half of this year and decide how to allocate free allowances to an estimated 480 emitters by June 2014, Lee Hyung Sup, a deputy-director at the Ministry of Environment, said in a phone interview yesterday in Seoul. Trials for carbon trading are set to start in June...
