Comment Re:Doesn't work that way (Score 1) 72

The concept of "offsetting" your bad behavior by purchasing carbon credits or investing in "green energy" is complete bullshit. It is the same concept that sociopaths use to justify their behavior. You can't buy your way to being good.

You know how to lose weight? By exercising. Even if you weigh 500 lbs and can only barely walk around the block once, by doing that pathetically inadequate one-block walk that you set up the conditions so that next week you can walk around the block twice, and next month you can walk several miles. Next year maybe you weigh only 300 lbs and can jog, and the year after that you've dropped to 180 lbs and can run a marathon.

Similarly, neither Apple nor any other industrial giant is going to be able to transition to 100% clean energy on day one. But they can start the transition, one small step at a time, and someday they'll get there, judgmental naysayers notwithstanding.

UFOs are often convenient cover for secret flight tests.

That gives the government an incentive to encourage UFO nuts. There are a few documented cases of UFO nuts being worked for years.

The types of Aliens people encounter varies around the globe (S. America, Africa; Eaters, giant jaws, football heads, Europe, N. America; Anal prober greys, Asia; another pattern which escapes me). So either most are culturally acquired or the earth is subdivided by continent/alien species.

Not all renewable resources require large area. Solar Space Power Satellites, e.g., don't require a lot of area, and have a potential smooth path of development (via powering other vehicles in space, e.g. allowing ion rockets to go beyond Jupiter without using on board fission power).

OTOH, SPSS aren't all that flexible, and if you use tightly focusable E.M. to deliver the power they have the potential to be dangerous. (Delivery to Earth by microwave looks pretty good, but it would louse up a part of the radio spectrum that can easily get through rain. And power transmission via laser is going to either be very low power or very dangerous.)

IOW, every single form of energy generation/delivery has it's drawbacks. Solar and wind can't be started up whenever you need them, e.g., necessitating lots of network ballast and storage.

Comment Re:Should have a Deep Impact.... (Score 2) 347

That's an overbroad statement, but it's true that this is being well oversold as a "clean energy source". But if it can be made to work properly there are several environments where it would be the best choice. The questions are things like "How much maintenance would it require?", "How self-contained can it be made?", "How small/light/cheap can it be made?" Etc.

This should produce a lot less waste than a fission reactor (though there are interesting claims being made about the molten salt reactors) and after full development might be the superior choice of power in places like Antarctica, the moon, Mars, interstellar ships, etc. The problem is getting from this early development model to a final model.
