The Space Island Project is a project whose goal is to create a stand-alone commercial space infrastructure supporting human business activities in Low Earth orbit (LEO) 400 to 500 miles above earth. The centerpiece of this project is the Space Solar Energy Initiative which will collect energy with solar panel satellites and then beam this energy to receiving towers on Earth using "very weak microwave beams." The goal was to have a massive space station in Low Earth Orbit with as many as 20,000 passengers to start and doubling the population every decade. This was intended to start by 2020 but this date was not accomplished.
