Device close to sun to focus energy to satellite in Earth Orbit for energy generation

+0
−0

The light from the sun is dissipated in a sphere, so there is a squared relationship between the distance from the sun. Would it be possible to place either a lens or solar collectors with a laser to focus energy from an area near the sun and sent it to a satellite in earth orbit which would in turn send it to the surface of the earth? I did some basic calculations and found that using a 1 sq meter of light, you could get about 1GW of energy if you were about 1000x closer to the sun than earth. If a 100m x 100m grid was used this would be 10TW which would be more that enough energy to power the earth. (All assuming 100% efficiency)

Would either the (multiple) lens or the power generation to a laser be a possible solution to transfer energy from an area close to the sun to earth?

I feel this is not a duplicate of this because this would not be used for fusion generation.
