The cheapest solution for them is an oil lamp and wood burning stove. As it is today, solar power is a toy for the rich. This will change in time. After all, cars in 1905 were toys only for the rich.

Yes, that is a good second eyepiece to get. It will give you 133x magnification, which is enough to view planets or other small objects. The 25mm, 48x magnification eyepiece that comes standard with your XT8 has a wide enough field of view for galaxies and nebulae. You can get wider field...

They are completely different and far apart. And neither one is a constellation. Orion is the constellation but Orion's belt it just part of the constellation Orion. The big dipper is the main part of the constellation Ursa Major, but is not the whole constellation.

0. No. 1. I don't know. 2. I don't think today's cosmologists say that. Some of them might, but not all of them.

You might want to learn about the orbits of the planets and how to find them in the sky. For example you said Mars is 38,000,000 Miles from Earth. That isn't usually true. That is the closest Mars can be to Earth, when both planets are on the same side of the Sun. When the two planets are on...

That is a false criticism. The usual complaint is about nickel. The amount of nickel used in batteries is small compared to the amount used to make nickel steel and other uses. I do not believe one single new mine has been opened that wouldn't have been if there were no hybrid cars. In fact I...

Lots of people with telescopes in the dark. Most of them will be happy to answer any questions you ask or let you look through their telescopes. They probably will even point their telescopes at objects you request and let you look.

It takes energy to make the hydrogen, and that has to be supplied by the engine that uses the hydrogen. So I can't see any benefit from it, but it shouldn't hurt the engine. You know gasoline is about half hydrogen and regular gasoline engine exhaust is about half water vapor. So a little more...

Ask other neighbors or other people near you to look at it and give their opinion. I have no way to tell what it is without seeing it myself.

Bigelow is working on inflatable structures to build a private space station. But he is contracting with others, including Space-X, to launch his modules. Armadillo Aerospace is still working on their vehicles but they are not even ready for suborbital flights yet, and don't seem like they will...

So far all the renewables are too weak and expensive. Many are not even new, and long since discarded in favor of cheaper and more powerful coal and gas engines. So basically renewables will become the only power source only when the non-renewables actually run out.

Lotta good ones in the other answers. Here are a few more I really like.
