How are you planing to steer the airship?

Here is a web page that will tell you everything you need to know. It pros and cons AC/ DC, helps predict energy requirements, gives avg energy drain of appliances, and has lots of good information on battery and generator care. http://www.cosolar.com/system_design/yourself.htm Also...

Thanks all. My question is satisfied.

More on Neural Nets If you want to design a relatively simple neural net with electronic parts, you can manipulate the know equations and figure out a combination that works. For these simple types, a builder chooses the desired state (or maybe states) // You could choose opposing states...

Excellent! Lots of different answers! (1) N0 : Redshift is caused by the expanding universe w/ Big Bang (2) YES: Because Redshift might be a property of light (3) NO : But w/o Big Bang; instead natural exp expansion Please tell me if I have misinterpreted your answers. One anti...

Have you considered neural networks? I am researching the details but here what I know- Engineers have made neat little "robots" that respond to stimuli, learn, and run around doing all kinds of weird stuff WITHOUT ANY PROGRAMMING. Imagine a chaotic jumble of wires connecting the input...

Are there other ways to explain redshift than an expanding universe?

If one ion drive can't beat Earth's gravity, then a hundred thousand all strapped together wouldn't work either. They would work LESS efficently because of the extra weight binding them together. One gigantic rocket using the same technology still wouldn't work. You would need a lighter...

Archaea has been found in the most inhosbitable places on earth. Deep underground, inside hot oil, inside artic ice. Oxygen is not required and I have read about types that eat metals for energy. Archaea is probably the microbe you are referring to pmb_phy. I am not an expert, but a...

Great information! Thanks

And Plasma cutters work by superheating gas which cuts the steel. Are two methods being discussed? one where electrodes run current through the steel, and one where electrodes run current through gas which melts steel? Method 1) Power Source -> Wires ->...

So you attach electrodes to the solid steel and use the heat created by resistance to melt the steel? What material do you use to supply the current?

How to melt Steel with Electricity? The question boils down to concentrating heat. You can force heat into a crucible with heat from resistive coils. Or you can zap the right material in a microwave and it will heat up. (Examples have found use graphite, magnetite, and silcon...

I looked at your attachment. I couldn't read the words but the diagrams are clear. It showed a cube transformed in various ways by current. By changing the location and direction of the current you could shorten (squash), skew, or bend the crystal. Right? So the cystal can get shorter or...

After looking around a bit, found that piezoelectric ceramics expand with electrical current and produce current when contracted. These properties make them extremely useful for pressure sensors and sonics, as well as solid state generators. Though they can vibrate extremely fast, I think that...
