It's no stranger than building a computer out of sand and minerals.

If by "electric force" you mean electric field strength, then no, it does not fall off linearly. It obeys the inverse square law -- same as gravity.

I was expecting this to be a true volumetric display. Nope. It's just a standard 2D projector projecting images on flat sheets of flowing water droplets.

Oxygen is most definitely not flammable. Please take a grade-six science class.

Jesus, does no one even read the summary? The drug isn't nicotine -- it's a genetically-engineered monoclonal antibody produced by the tobacco.

You're thinking of Pluto.

Chernobyl was a fission plant. Mankind has yet to create a viable fusion power plant. And even if we were able to make a fusion plant, it would be impossible for a fusion reactor to "go critical" since "criticality" is not even a concept applicable to fusion reactions.

Why do you keep posting that?

Huh? Yes, certain types of thin-film cells use rare and toxic metals. But what about plain old silicon cells, which make up a majority of the PV market? They consist of:

- silicon (extremely abundant and non-toxic)
- aluminum for the contacts
- tiny amounts of boron and phosphorus as dopants.

I know you're joking, but how can an ablative process be used to deposit material? They're kinda the opposite of each other.

I highly recommend a program called Celestia. It not only shows star charts, but it allows you to explore the local universe in 3D. A similar program is Space Engine, although I don't think it's as polished and complete yet (although it may have a better renderer).

Purposely. Purposefully means something else.

Teflon is not, to my knowledge, very elastic. It's essentially a rigid plastic. Condoms need to be able to stretch and experience, ahem, rather extreme dynamic loads during use. They need to be quite stretchy so that they don't tear.
