Need back to the ground. On the burning laser pointer, I know, there are two forms of vision, is a minor, not easy to solve power transmission area, such as unmanned area (desert, Gobi), so there a microwave receiving station is relatively safe, harmless to humans and animals. This energy is not too large; another version is a path to Communism: completely solve the energy problems of mankind.
Burning laser pointer to solve large bodies of launch, on orbit assembly attitude control problem, but also solve the problem of large current transmission (HTS), so I suppose to this step, we have made remarkable progress in materials, today that idea is not realistic, that time has been achieved.
For example, light, rigidity and good material, can control the shape and attitude on a large scale, after all, this is the “burning laser pointer” must. For example, large buildings on the ground to consider air disturbance, resulting in angular momentum to control, also led to the need to maintain the shape of space solar panel array; as to consider the radiation and cosmic rays, because light sail huge solar panels equivalent to the efficiency is not too high…
In a 200 km radius of the burning laser pointer Ferris wheel, electric vehicle transportation cycle down out of the battery, charging in low earth orbit. If full Ferris wheel diameter, with a single row of 1865 lithium battery 3.2V, 1000mAh full capacity (new battery 3000mAh, scrap, even with 1/3 capacity), then a turn can transfer 200 thousand kwh!
