X-ray emission from interacting massive binaries: a review of 15 years of progress [PDF]
, 2015 Previous generations of X-ray observatories revealed a group of massive binaries that were relatively bright X-ray emitters. This was attributed to emission of shock-heated plasma in the wind-wind interaction zone located between the stars.

Contemporary wind generators [PDF]
Journal of Energy in Southern Africa, 2014 It is believed that wind energy is growing at a very rapid rate, especially in the last few years. When compared with other sources of renewable energy in the energy portfolio, it becomes evident that the bulk is wind energy-based. However, there are some backlogs to full manifestation of this technology ranging from initial high cost to performance ...
