This, along with the long-life light-emitting diode which does not burn out like an incandescent bulb, give the flashlight a long lifetime, making it a useful emergency light. A disadvantage of many current models is ...
Philips Lighting ceased research on compact fluorescents in 2008 and began devoting the bulk of its research and development budget to solid-state lighting such as LED lighting.

The ship would first drop into an orbit making a close pass to the Sun, to maximize the solar energy input on the sail, then it would begin to accelerate away from the system using the light from the Sun. Acceleration will drop approximately as the inverse square of the distance from the Sun, and beyond some distance, the ship would no longer ...
The drivetrain includes a Fishman-designed 20 hp (15 kW) motor, electronic controller and 3.3 kWh LiPo battery pack. An additional 3.3 kWh battery pack is a US$5,000 option, which gives a two-hour endurance. A two-bladed fixed pitch propeller is standard equipment, but a folding carbon fiber propeller is optional.
