Goldenrod Gall Contents
Apparently all kinds of things go on inside goldenrod galls, beyond the caterpillars who make them. Fascinating. I've seen the galls but haven't…

I also live within 60 miles of a wind energy producing area. The wind mills are getting bigger and more sophisticated all the time, but they also have their problems. One of them is that they sometimes kill a number of passing birds. Another is the cost of producing electricity, and their upkeep.
Also nearby--within 80 miles--there are geothermal fields which produce electricity from superheated steam released from the ground. They are the most efficient electricity sources. But, of course, not everywhere has a geothermal "hotspot".
All these things, and many more, ned to be used as energy producing sources. And that is being done in California. Though like the rest of the country, things move slowly.

* Transport costs. It requires massive expenditures of energy and resources to move even small things from Earth to space, or from space to Earth in a safe controlled manner. Future technology may make this much easier and more affordable, but probably not *cheap*.
* Nonlocal dependence. It's bad enough that our cities, and heck, even our countries now, can't support themselves without imports. Putting the whole planet in that situation would be a big step in the wrong direction.
* Accident hazards. Yes, toxins and explosions and such are bad on Earth. They're a great deal worse if something gets dropped from way high up. No industry is immune to accident; space industry accidents tend to be big.
Space industry is most useful for building things on the spot with materials already in space: mining asteroids for raw materials, machining them in a space factory, and using them to build ships or stations.
