DE-STAR space system is designed to vaporize or off course Earth-threatening asteroids. And this is not scientific science fiction – this technology can work in practice. System DE-STAR looks like an open book, with lasers on one half, and a photovoltaic panel to receive energy from the Sun on other. By synchronizing the laser beams, you can get phased flow which creates quite impressive 70 gigawatt output beam. Here’s how it works: System control, located on board the device, takes orders, which she should attack the target. Then the laser beam creates a spot near 30 meters in diameter on an asteroid that is on the same the distance from the satellite at which we are from the sun. This beam raises the surface temperature of an asteroid to several thousand degrees Celsius – this is enough to vaporize any known substance. In less than an hour, DE-STAR is able to vaporize an asteroid the size that exploded over Russia this winter – if his approach is noticed on time. Plus to that, evaporating, the substance of the asteroid creates a momentum in the opposite direction comparable to a space shuttle rocket booster. This means that with shorter laser pulses an asteroid can be deviated from the course, instead of burn.

DE-STAR can also energize anything located on Earth or in space. With it, you can send developed by him energy to any point – but not through a laser, but through a microwave radiation. Also its beam can be used to directly move any spacecraft. But here the main difficulty of this technology: for the complete evaporation of an asteroid, each turn of the “book” should be 10 kilometers long. Us never had to build structures of this size in space, however, with a sufficient concentration of social efforts, this is possible in the next 50 years. And since the system is completely modular, you can start with much smaller scales. For example, a meter-by-meter book can cook your lunch from a distance of 1000 kilometers.
