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]
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.
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 ...
Laser (dinghy) The Laser is a class of single-handed, one-design sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Ian Bruce and Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance.
The Laser Pico has no active Class Association with the last remnants of the website being removed in 2013. Specifications.

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 ...
Forces on sails. Aerodynamic force components for two points of sail. Left-hand boat: Down wind with stalled airfow— predominant drag component propels the boat with little heeling moment. Right-hand boat: Up wind (close-hauled) with attached airflow—predominant lift component both propels the boat and contributes to heel.
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.
Sailing hydrofoil. A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed.
