I've never understood some people's fascination with space-based solar. Why go to all that over-engineered trouble to do something you can do on Earth anyway, except in an orders of magnitude simpler way.
Also, I love to see people devote efforts to space development, but it depresses me to see people do it and waste their time. I know it's a simplistic way of looking at things, but I wish they'd devote their time to something useful, like creating a commercial space station.
Its hard to imagine a future where humans expand into space without space stations.
