Put simply volts push electrons around a circuit rather like a pump pushes water around pipework. Another name for the voltage is electro motive force usually abreviated to e.m.f.. The flow of electrons going around the circuit is called the electric current and is measured in amps. This is similar to thinking about water flowing around pipework which could be measured in gallons per hour. Voltage is a force. Current is what results from that force.

This is more tricky than at first appears. The rating on the power supplies will be a given maximum and only developed when connected to the value of resistance load that results in the maximum rated current. Even that ignores internal resistance of the power supply. What I am getting at is if both power supplies are connected to a high resistance load the 15V power supply would produce more power in the load than the 9V power supply (and in both cases less than the maximun rated power). If you are considering electrolysis of water this may well be a high resistance application.

I'm not a mathmetician so I have only glanced at your formulae but I don't see any reference to the size of the globe. For example if the globe is very large and the distance involved is small then the surface will be almost flat and so you would get a good approximation using a right angled triangle with straight sides. If the globe is small and the distance relatively large then your "triangle" would have strongly curved sides. I can't help feeling that the size of the globe is an important factor - sorry if I am wrong about that.

I guess your "straight line" on the surface of a globe is the shortest distance between two points travelling along the surface of the globe. (i.e. actually a curved path). If I am correct then you are looking to calculate the part of a Great Circle that joins the two points. If you google "great circle" you will get lots of information.

Some people think that some sudden sinking of ships in the Bermuda Triangle may be due to a huge release of methane hydrate from the sea bed. The bubbles would reduce the density of the sea water making the ships sink. Whether this is true or not, released gas would certainly bubble its way to the surface.

I notice you are using two antivirus programs. This is not recommended as they can trouble if both are running.

Don't forget that you can't get more power from a generator than you put in (Power = joules of energy per second Watts). A small head of water coming out of a water butt through a small pipe won't provide enough water flow to drive anything but the smallest of generators. I think lighting something like a torch bulb would be a more realistic aim. If you are thinking of using the water mains pressure to drive your turbine the water company might not like that as presumably the water used would be wasted. In theory a larger container providing a greater head of water delivered through a bigger pipe could be effective in driving a bigger, or more powerful, generator (at least for a short time).

If you google - science fair wind generators - you may get some ideas. Basically they describe how you can use an electric motor as a generator. You can drive the motor from your turbine to make it generate electricity.

I think the best outcome you could expect from your algorithm would be an answer to the question "what would be a sensible decision based on all available inputs?" This may be quite different from what decision would a human being make?". If you succeeded in only making a sensible decision your algorithm would have quite a lot to commend it. I remain convinced that two humans provided with identical inputs may well make different decisions. Anyway - best of luck. By the way programming languages mean you don't have to get right down to "1"s and "0"s to get a computer to do what you want.

Agree talking about efficiency is misleading. You might as well claim a solar panel is infinitely efficient since you (personally) put nothing in yet get power out of it. I don't agree that Geothermal energy is a form of fossil energy. The heat inside of the earth is due to several factors, but not due to the burning of fossil fuels. The heat originates from the original formation of the planet plus some other factors such as radioactive decay.

You should note that simple electric motors and simple electric generators are really the same thing as far as construction is concerned. In other words you need to decide whether you want to determine direction of movement of a current carrying conductor in a magnetic field or whether you want to determine direction of current in a conductor that is moving in a magnetic field. These are different and there are two similar rules that cover the two situations. These are Fleming's left hand rule for motors and fleming's right hand rule for generators. You can easily find details by googling - Fleming's right left hand rules-. As a memory aid to decide whether you should use the Right or Left hand rule I used to say to myself gener-right-ers.

It seems the logical conclusion of your aim would result in no free will. If every human outcome could be forecast from an examination of all data inputs what should we do with a murderer who followed your algorithm and killed someone? You might say that giving a numeric value based on emotion would cover that. However the murderer's emotional makeup would be beyond his control. If the murderer was sane, however angry or emotional he felt, he should be able to restrain himself. Perhaps a numeric value should be used for degree of insanity. After all IMO none of us could call ourselves completely sane all of the time! For some reason we all do daft things now and again - I do anyway!

Selective breeding of dogs has shown that the characteristics of a species can be changed. To the extent that a wolf can eventually give rise to animals as different as spaniels and rottweilers. This shows that large changes in an organism's characteristics can take place over time . I feel this is evidence that evolution is probable. I suppose the fact that nobody has changed a dog into a cat by selective breeding is a problem for some people.

("Physicist John Wheeler once offered a suggestion: maybe we should approach cosmic fine-tuning not as a problem but as a clue. Perhaps it is evidence that we somehow endow the universe with certain features by the mere act of observation. It’s an idea that Stephen Hawking has been thinking about, too. Hawking advocates what he calls top-down cosmology, in which observers are creating the universe and its entire history right now. If we in some sense create the universe, it is not surprising that the universe is well suited to us.”- cabinintheforest) If the human race manages to annihalate itself (as seems quite possible) will the universe disappear? Will it go out with a bang or a whimper?

How about trees? See "Reverse global warming"

Thats o.k. but the alternator which is usually belt driven by the engine already does that. One advantage is that electrical power is available all the time the engine is running, even when the car is moving slowly or stationary.

I think your algorithm would need a measure of randomness about it. For instance I usually travel from A to B by a particular route. This route has much to recommend it such as shortest distance good roads etc.. However for reasons unclear to me, although I may have set out intending to follow my usual route, I suddenly decide to vary it and follow a diversion. If my passenger says "why are we going this way?" I have to reply "I don't really know - perhaps I just fancied a change".

If you are thinking along the lines "I'll use the output of the dynamo to power the car and travel for nothing" then forget it!

Yes - a small amount. I would say that as a general rule anything you find useful that uses electricity will cost you (or in some cases someone else) money. I'm afraid it's a case of nothing for nothing!

I think the advice given is don't leave transformers or small power supply units such as used by mobile phones plugged into a power socket when you are not using them. These devices use a small amount of power under these circumstances. The power they take creates heat. As the amount of power they take is small the temperature rise will also be small. It is much the same as leaving equipment such as television sets on standby. To answer your question - if you leave your power cord alone connected to a power socket it will take a tiny amount of power, really so tiny it can be ignored under normal circumstances. The reason is that a tiny electric current will flow due to capacitance between the wires and this tiny current will in turn generate a tiny amount of heat in the wires due to their resistance.

I sometimes wonder if "Swansont" is really a computer running an artificial intelligence program. I mean this as a compliment as he seems to be able to give precise answers to so many queries listing the relevant laws and theories. On the balance of probabilities he is probably a very intelligent human - but I do sometimes wonder! Please Swansont do not be offended - take this as a compliment.

I was just wondering - I suppose you have the coils joined so that they all work together when under the influence of the changing magnetic fields. i.e. produce voltages that are in phase. If not then one or two of your coils could be reducing output. This does not seem likely as you seem to be generating a large voltage from a high resistance source (your generator).

It is a fact that I take a combination of drugs to combat the effects of coronary heart disease. Someone once asked me whether I was aware that all drugs have side effects. My answer was that I was aware of the side effect associated with not taking them - I die! Keep taking the tablets!

A radar transmitter uses several kV to generate power in the order of MW (peak). By the time it is received as an echo from a distant aircraft the power may well have a peak power measured in mW from which you may detect a a signal measured in mV. This is just one example of changing amplitude of an electromagnetic wave.

Thank you all for your advice. I think the "Today's Active Content" link will suit me very well. I hadn't noticed it either. As far as I am concerned I see no need to alter the site's software. Thank you again.
