High revving engines on highways like high flow thinner oils but low revving highly loaded engines e.g. trucks like thicker oils due to the bearing loadings.

When I start my car the oil is thicker than it should be for my engine, with the above statement in mind would it therefore be better to keep the revs low and labour the engine more, as the thicker oil would protect the bearings better than the cams due to inadequate flow.

ok ok I know about power stations and transformers, but how when i plug something in is electricity waiting. Is it like water drawing on a big pool of electricity or is electricity so fast that you put a turbine on and immediately I have power! what happens when not enough is used, does it just sit there waiting to be used?

I'm Designing a peice of furniture and have reached a problem with its structure. I need some advice by some one with knowledge of matterial strengths to advise me on joining two sheets of material. Can any one help?

I will be more specific then. I'm trying to join two sheets of 18mm thick poplar plywood board together at 90 degrees. it needs to be mega strong but not be any thicker than the 18mm. I thought of dovetail joints but i can add components to make it stronger. additional components could be used.

Many people think of strong artificial intelligence as an artificial device being able to perceive, and reason, in ways similar to a human being. I agree that there are other, lesser bars for artificial intelligence, but the difference is why I use the term "strong AI".

I have been researching op amps recently, and I have been wondering: can they amplify DC power? I know power is the product of voltage and current, and I know they can amplify voltage and current, but is the power delivered to the output higher than what you start with at the input?

The poles around here have been buzzing since I went outside today. This evening I saw they were all arcing across the insulators. I've messed with St. Elmo's fire before, and its nothing like that.

Okay...
Electricity moves through objects or from one object to the other, so it's sort of 'outward' in that manner, right?

So here's the question:
Is there such a thing that PULLS electricity towards it?

(I don't mean "ATTRACT", that would just mean supplying the electricity a pathway through continuous conductivity.
I mean "PULL")

You see, I was thinking this: Many people suffer prolonged muscle spasms.
Electricity is often used (especially in therapy) to stimulate muscular movement through contractions, much like spasms.
Now, IF it were possible to suck out/ pull/ extract the accumulated bio-electricity in a given part of the body, then THEORETICALLY the spasm or muscular contraction could be undone.

So... about my question: Is there such a device or 'phenomena' that pulls electricity?
