That is why I said it needs a sat, but in the unit discription thing it says:
The satellite in high planetary orbit collects sunlight and converts it using photovoltaic cells into electricity, which in turn powers an array of MASERS, the microwave equivalent of a laser. These produce a narrow, high-energy beam of microwaves that must be aimed precisely at the small target the Solar Power Array provides, but which can be collected by a relatively small antenna array with negligible losses. This antenna converts the beam back into electricity, which in turn is broadcast for use by colony structures and vehicles.
We cant use a mobile one. If it didnt need a sat, it would have to be 4 starports and only work half the time.
