With any intelligent socially interacting species, I suspect, such evolutionarily advantageous features are sure to be an exaggerated part of the species anatomy. It's the non-rare boob theory of exobiology.

Don't despair, you mentioned several nutrient sharing methods that animals on earth have. An enlarged gland that secretes nutrient solution has many advantages and may be common in the universe. They may have variation in location, number and type, but I'm sure there are analogues on alien species. That is, if we ever could observe them.

Rose wood is contraband. As such any illicit grow operations must be shut down and the contraband destroyed.

But there is gravity inside the air plane.

Exactly! There is nothing wrong with what they are doing. The air plane is not for going in to space. It's how they will sharpen their skills. Then they will move on. This clean slate method can work. I don't know how long it will take and at some point they will need to procure a lot of fuel and materials but the project is in its planning stage. Good luck to them.

True, but Poor Richard would.

Isn't more jobs per megawatt-hour a fail for solar.

Ok, go build me 2809 square miles worth of heliostat reflectors smarty pants. The problem with solar power in not it's abundence. It's how diffuse it is. People are small and can only do somuch work to get this energy. After a while it makes sense just to dig coal not that there aren't better alternatives.

You also must consider how many lifetimes worth of effort are wasted per twh. Some renewable systems consume many man hours and just don't produce the energy compared to other systems. How many lifetimes are spent building and maintaining a million windmills compared to a nice compact plant with a powerful and efficient steam turbine.

The Trojan Horse was in Troy.

Look they don't actually have to do anything. Just say it and win the war. The enemy just jumps off a cliff while pissing his pants. This is what the the TSA is all about. We just piss and jump.

Dentist stand behind a lead shield and the patient wears a lead apron that covers the gonads.

A certain percentage bounce back. The rest pass through and are absorbed or lost in other directions from the detectors.

The X-rays stop in a thin layer of skin. That's funny.

I worry more about the danger of putting my groin into these things. Will my children have leukaemia and other hereditary genetic damage. Where the hell is the damn nuclear regulatory commission on this? Because this is their mandate.
