Light sail. The light sail is envisioned to be no larger than 4 by 4 meters (13 by 13 feet), possibly of composite graphene-based material. The material would have to be very thin and be able to reflect the laser beam while absorbing only a small fraction of the incident energy, or it will vaporize the sail.
Solar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s.
LightSail is a project to demonstrate controlled solar sailing within low Earth orbit using a CubeSat. The project was developed by The Planetary Society, a global non-profit organization devoted to space exploration. [5] It consists of two spacecraft — LightSail 1 and LightSail 2.
Laser propulsion systems may transfer momentum to a spacecraft in two different ways. The first way uses photon radiation pressure to drive momentum transfer and is the principle behind solar sails and laser sails. The second method uses the laser to help expel mass from the spacecraft as in a conventional rocket.
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.

Peach 2 IPL. Just like the majority of Foreo's buzzy devices, this IPL hair removal tool is extremely high-tech—it even comes with its own app. The tool uses up to 120 flashes per minute and T ...
One example is using a solar sail to reflect a laser beam. This concept, called a laser-pushed lightsail, was initially proposed by G. Marx but first analyzed in detail, and elaborated on, by physicist Robert L. Forward in 1989 as a method of interstellar travel that would avoid extremely high mass ratios by not carrying fuel.
Solar-pumped laser. A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium. This type of laser is unique from other ...
The Laser Standard or ILCA 7 is a popular one-design class of single-handed sailing dinghy, originally built by Performance Sailcraft Canada. The laser is cat rigged, with a single mainsail and is a simple, light and fast boat to sail.
The Laser Radial or ILCA 6 is a popular one-design class of small sailing dinghy, originally built by Laser Performance. It is a singlehanded boat, meaning that it is sailed by one person. The Laser Radial is a variant of the Laser Standard, with shorter mast and
