Pick a model with sizable knobs and buttons for the audio and climate control systems along with power-operated mirrors to help reduce the amount of grip strength needed and reduce pain associated with turning or twisting motions.
Extras: On my test cars additional features included the moonlight blue metallic paint, allroad Premium Plus Model with auto-dimming interior mirror with compass, auto-dimming power-folding, heated exterior mirrors, Audi music interface with iPod cable, Bluetooth, driver information system, heated front seats with driver memory, HomeLink garage door opener, Audi xenon pluse lighting with LED DRL, three-zone climate control and power tailgate.

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.
Tellingly, about two-thirds of bids for solar energy contracts last year (by electricity generated) were for photovoltaic projects and only a third were for solar thermal power plants, which deploy vast arrays of mirrors to heat liquids and produce steam to drive an electricity-generating turbine.
FORBES: California Reveals Price It Pays For Renewable Energy
The solar thermal power plant business is all about big: Square miles of mirrors in the desert that surround 600-foot-tall towers to generate massive megawatts of electricity for multibillion- dollar price tags.
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.

The standard equipment furthermore includes electric windows and electrically adjustable door mirrors, a leather steering wheel, leather gear knob, the entry line radio, power steering, 9-spoke alloy wheels and a luggage compartment cover.

When a receiver will generate about 25kW of energy while costing less to make through cheaper mirrors and structures, a fully developed solar array could be an affordable replacement for coal power that delivers greater independence -- picture remote towns that need a fresh water supply.
He dreams of building gigawatt-size plants, of shipping solar thermal power to the cloudy Northeast and of using molten salt to store energy so thermal plants can power homes at night. (Nevada Solar One is only for daytime peak loads.) He envisions mirrors in space that can soak up sunlight 24 hours a day.
