Solar cells are also made of silicon, and the latest fashion is to concentrate sunlight on them using mirrors.

Yet you give the clear impression that HHV is somehow using smoke and mirrors to meet FORBES' efficiency standards.

FORBES: Clean Hit?

Utility-scale concentrating solar power (CSP) systems that produce electricity using lenses or mirrors to focus radiation on thermal collectors or photovoltaic cells draw criticism from environmental groups for taking up too much desert land, thus displacing certain animal and reptile species.

Ivanpah is a solar concentrator project, using fields of mirrors, known as heliostats, to concentrate sunlight onto a solar receiver on top of a tower. (This project when finished will include 173, 000 heliostats.) The concentrated sunlight is used to heat water, generating steam which is used to turn a traditional turbine and generator to produce electricity.

The blue painted routes are designed to make it safer by, among other initiatives, widening the lanes and using large "Trixi" mirrors to give drivers better views of cyclists.

BBC: Plan for fifth London cycle superhighway unveiled

BrightSource generates electricity using an approach called concentrated solar power, in which computer-controlled mirrors, known as heliostats, focus the sun's heat to boil water and turn a steam turbine.

ECONOMIST: Energy storage

Rather than being single instruments with large, lone mirrors, each of these new devices consists of several small interconnected telescopes, whose images are combined using a technique called interferometry.
