Unfortunately, I don't have a solution. For microwave optice reasons,<br>
the size of a power satellite optimizes around 5 GW. The demand of a<br>
big forward base is around 5 MW, so we are talking about a scale<br>

locals. Make a profit center out of a forward base.<br></blockquote><div><br></div><div>That is an option too. But I suspect they would prefer a less-than-optimally-efficient 5 MW power satellite.</div></div></div>
