Laser propulsion. Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board ...
The Laser 2 is a sailing dinghy, built predominantly of fibreglass. It has a fractional sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller with an extension and a retractable daggerboard. It displaces 170 lb (77 kg). The crew can make use of a single trapeze. [3] [4]
Beam-powered propulsion, also known as directed energy propulsion, is a class of aircraft or spacecraft propulsion that uses energy beamed to the spacecraft from a remote power plant to provide energy. The beam is typically either a microwave or a laser beam, and it is either pulsed or continuous. A continuous beam lends itself to thermal ...

2000 (dinghy) The 2000 (formerly the Laser 2000) is a performance sailing dinghy designed by Phil Morrison and currently sold by RS Sailing. It combines a traditional GRP hull and foam sandwich deck moulding with a modern asymmetric rig including a furling jib, reefing mainsail and single line gennaker hoist system.

A useful analogy to solar sailing may be a sailing boat; the light exerting a force on the large surface is akin to a sail being blown by the wind. High-energy laser beams could be used as an alternative light source to exert much greater force than would be possible using sunlight, a concept known as beam sailing.
Following his "doodle" Kirby developed working drawings that Ian Bruce used to develop the Laser. The plans stayed with Kirby and Bruce until 1970 when One Design and Offshore Yachtsman magazine held a regatta for boats under $1000, called "America's Teacup." After a few sail modifications, the Laser easily won its class.
When a small sailboat flips on its side, the keel can also be used to right the boat. Standing on the keel gives the sailor additional leverage to roll the hull upright. The centerboard, daggerboard, or bilgeboard can be used as a platform upon which to stand, providing increased leverage, in the event the dinghy overturns via a capsize or turtle.
Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, [1] to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark ...
