star of death will be a source of energy   In a possible global energy crisis, scientists around the world have long been thought to the possibility of collecting energy in space and a way of sending him to the ground. Work on these issues under the auspices of the U. S. government began as far back as 70 years of last century, but the best solutions have so far not been found. The most first and most promising projects on space power project was Solar Power Satellite (SPS), which was planned to explore the possibility of placing a geostationary earth orbit an artificial satellite, generating electricity from sunlight using photovoltaic large.
In a preliminary analysis of the project was revealed that even a small satellite will be able to collect the amount of power comparable to the number, generated the largest hydroelectric power station earth. For the system to the deployment of batteries in space has great potential:ground-based solar cells is highly dependent on the weather and with the passage of light through the atmosphere lost about 40 percent of energy that significantly affects the efficiency of terrestrial photovoltaic. But, as a result of that analysis were visible and obvious disadvantages of the project - a very high cost of equipment and construction, and heavy losses in the delivery of electricity to land (about 30 per cent).
Despite the obvious shortcomings of the project work on it was suspended, but not completely frozen - documentation and research results have been postponed in the archives until better times.
The development of advanced technology has increased the efficiency of PV by 40 percent, disappointing loss in the transfer of power to the ground and develop ways to collect chips in space greatly facilitated their creation directly in orbit. All this helped to raise the documents on the draft SPS, and on its basis to begin work on a new, more promising and, most importantly, feasible project, called Space-Based Solar Cells (SBSC). On draft SBSC the U. S. government pledged $ 10 billion and provide a period of 10 years.
The first stage is planned to create a prototype satellite, the ability to collect and transmit to ground through an electromagnetic beam up to 10 MW of electricity. One of the biggest technical challenges will be the creation and delivery of a satellite into orbit, mass nearly 10 times the mass of the International Space Station (about 3000 tons). According to the model created by computer modeling system SBSC appearance will remind many well-known stars of death - the ship-planet from Star Wars:the same wings of photovoltaic, electromagnetic gun and receiving antenna, located on the ground. This will be possible only if the U. S. will reduce the current number of space launches. In the year the U. S. will initiate no more than 15 launches, and to create SBSC will need at least 120.
In the future, placement in geostationary orbit the planet PV 1 square kilometer as a result should help get the amount of energy equivalent contained in all known fossil reserves of conventional oil on Earth. Sorry about how to operate electromagnetic transmitter and receiving antenna so far unknown, but we will follow developments of this interesting and promising projects.
