Bright future of solar lighting
Hybrid solar powered lighting (HSL) isn't anything like solar light based power that changes over daylight into power. Through the utilization of optical strands, HSL catches daylight, diverting it and funneling daylight into a building. At the point when there is practically no daylight, these installations use power with the goal that consistent lighting is accomplished. Gatherer units, ...

The alternative to coal in South Africa
With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned about carbon ...
