      How It Works: Laser Beaming Recharges UAV in Flight its foot wing positioned vertically to expose the photovoltaic panel to LaserMotive's system as it beamed power to the receiver . No one wants a space-based solar power system that works only when the sky is clear. But microwaves—for example, ones with wavelengths between 5 and 10 centimeters—would have no Author: Susumu Sasaki.

    For decades, engineers have made halting progress toward designing the basic components of a space solar power array: a massive photovoltaic or thermal orbiting generator, a microwave or laser. The integration of photovoltaic (PV) systems to electricity networks is covered at the top level in the standard, which groups the issues into two main categories: safety and power quality. Safety of .

    The power beaming system uses a laser running from a power supply. To define the beam size at its destination, the laser's light can be shaped by a set of optics. This light energy can be sent through air Headquarters: Kent, Washington.   The core idea of space-based solar has been in development since the s: Place solar panels on a satellite, beam the collected energy to a receiver on Earth, and convert the beam .

PHOTEVOLTAIC RECEIVERS FOR LASER BEAMED POWER IN SPACE Geoffrey A. Landis Sverdrup Technology, Inc. Lewis Research Center Group Brook Park, Ohio ABSTRACT There has recently been a resurgence of interest in the use of beamed power to support space exploration activities.

One of the most promising beamed power concepts uses a laser beam to. Research on the mathematical and simulated models of photovoltaic cells for laser power beaming in space Study on the Far Field Laser Power Density of the Laser-UAVs with Photovoltaic Panel Cited by: Using photovoltaic arrays as the receiver also has many advantages.

Several applications for laser-beamed power are shown in schematic in figure 1. One application for laser power is to power a satellite during eclipse [4].

The solar array needed to receive the beamed power. Get this from a library. Photovoltaic receivers for laser beamed power in space.

Photovoltaic receivers for laser beamed power in space Abstract: One of the most promising beamed power concepts uses a laser beam to transmit power to a remote photovoltaic array.

Large lasers can be located on cloud-free sites at one or more ground locations, and illuminate solar arrays to a level sufficient to provide operating power.

Photovoltaic receivers for laser beamed power in space. By Geoffrey A. Landis. Abstract. There has recently been a resurgence of interest in the use of beamed power to support space exploration activities.

One of the most promising beamed power concepts uses a laser beam to transmit power Author: Geoffrey A. Landis. In laser electric propulsion (LEP), power is beamed to a photovoltaic collector on a space vehicle, where it is converted to electricity for an ion engine (Holloway and Garrett ).

The central power station can remain fixed, generating the laser beam and aiming it at the spacecraft receiver.

When we first heard about the Solar Power Satellite via Arbitrarily Large Phased Array (SPS-ALPHA) – a proposed flower shaped solar power energy collector that beams down concentrated microwave.

In future space missions, free electron lasers (FEL) may be used to illuminate photovoltaic receivers to provide remote power. Both the radiofrequency (RF) and induction FEL produce pulsed rather than continuous output. In this work, the authors investigate space power solar cell response to pulsed laser light.

Space solar power has to deal mainly with expensive launch costs ofabout $15, per kilogram, as well as the huge capital costs of buildingground arrays if RF technology is involved. The photovoltaic array converts the sunlight into electricity, which in turn is converted into RF electrical power (microwaves) that are beamed wirelessly to ground-based : Scott Snowden.

This book makes the Case for Space Solar Power; recounting the history of this fascinating concept and summarizing the many different ways in which it might be accomplished.

It describes in detail a highly promising concept – SPS-ALPHA (Solar Power 4/4(12). Laser power transmission involves the transmission of power from a laser source either through free space (power beaming or PB) or via a fiber-optic cable (power over fiber or PoF) to a photovoltaic (PV) receiver.

The PV receiver includes a PV cell, or an array of PV cells, optimized to convert a specific laser. The idea of transmitting power from central power stations in space by using laser beams has been pursued by NASA since the early 's (refs.

1 and 2). The basic idea is to use a power source (e.g., nuclear or solar) to generate a powerful laser beam and transmit the beam, collimated and focused, to user locations where its power File Size: 1MB.

In the future, vast solar power satellites may beam energy to the Earth from space. This is the first episode in my series "Resources from Space". You can watch the other videos here:. The basic idea of space-based solar power was first investigated in the s, when solar panels were positioned on a satellite to beam the collected energy from the sun to a receiver on Earth to be converted into electricity.

If the sunlight were collected in the vacuum of space. A laser pilot beam guides the microwave power transmission to a rectenna. Inscience fiction writer Isaac Asimov published the science fiction short story "Reason", in which a space station transmits energy collected from the Sun to various planets using microwave SBSP concept, originally known as satellite solar-power.

Photovoltaic receivers for laser beamed power in space By Geoffrey A. Landis Topics: SPACECRAFT PROPULSION AND POWERAuthor: Geoffrey A. Landis. space-based solar power Loca miles above Earth, a solar power satellite uses mirrored panels to collect continuous energy from the sun.

It then redirects the energy onto concentrating photovoltaic arrays, which convert it into electrical power. Lasers to beam energy to Earth from space Solar energy collected in space and beamed back to Earth by laser could soon be used to power homes and electric vehicles under a project by .Using an orbiting space based solar power station to generate electrical power and beam it to a base sited anywhere on the Moon is a near-term option that should be considered.

The technology to collect sunlight, generate greater than the estimated 35 kilowatts of required power, and beam .
