It's always like that.

perfect quintessence of asian mentality. Knowing does not equate to comprehending. evryone thinks so highly of oneself. no wonder the word creations/breakthroughs never revolved around nerdy,arrogant asians

By applying Pascal Principle??using enclosed fluid system?

where

F1 / A1 = F2/ A2

1 = input
2= output

The output Force depends on the :

Ratio of A2:A1
Input force

correct me if i m wrong...

Energy can't be created nor it can be demolished. It only can transfer from one medium to another..
So, i think no one could argue on this..

You are right. But you need to displace the same volume of fluid in order to achieve that. Since volume = area x height,

A1 x H1 = A2 X H2; (replace this into your first eq. F1/A1 = F2/A2)

F1 x H1 = F2 x H2

Remember work = force x distance. You still spend the same amount of energy/work to achieve the same thing, except you did it the other way round. Same goes to car jack.

It's like, using a motor to turn a dynamo (generator), and as the generator turns, it generate electricity. We then used the electricity to power the motor, so that it could continuously turn the dynamo. Then, by using more powerful magnet, we could generate larger amount of electricity, hence allow us to generate more energy. (which is impossible, because the resistance from the magnet will prevent the core from turning. And for that, we need more electric energy to power the motor, which in return cancel the positive energy).

Before anyone is confused, oil (or more specifically, hydrocarbon) is highly unstable, which allow it to release high amount of energy when it is raised above the stable region (aka easily combust at high temperature). It is basically a form of chemical energy (latent energy).

Although it is true that we use a fraction of resource(energy) to extract a larger amount of energy, we can't claimed that we "created" it. We simply harvest" it.

Not really. See his wind/solar example. It's clear that to his interpretation, 'energy is created' [see his first post - since solar panels do end up paying back quite a lot more than the initial energy investment into them] when all we've done is to harvest the source of energy that's been untapped for a long long time, and not violating conservation of energy. Sure he uses words that look like conservation of energy is being violated when it's not, but that's just his vocab.

So yes, it's a matter of semantics here, and it matters.

in step up transformer, voltage is stepped up.

Power= voltage X current

Voltage UP, power UP

WOOT ME EINSTEIN

no sh1t sherlock, ever checked what currents are induced on the up-side?

hahaha, if you step up a 1V 1W source to 1000000000V, you will have 0.0000000001A as a current.

that means the power is constant?

It's already mentioned several times here that energy cannot be destroyed or created. Power is basically the rate at which energy is produced/consumed. You transformer doesn't add additional energy into the system, how do you expect the power output to increase?

Yes because energy cannot be created no matter what you try to do. Infact, in a step up transformer you WILL lose power, because you don't have ideal conditions. Another thing which doesn't exist, ideal environments.

In this post, I can only say that, by so far, there are four physical parameters known to be conserved.
1. Energy
2. electric charge
3. Angular momentum(Include linear momentum)
4. mass

Using this four principle, you will know that you are not likely to get bigger joule from smaller joule. In fact, second law of thermodynamics is one of the law that prohibit such incident.

As for the concept of the so called "asian mentality", i can only say, even western country people also take their times to develop themselves. As for slow development of scientific knowledge in asian country, i can say it is the society interest and political interest in Asian country is different from Europe. It is the environment which eventually lead to such great difference. However, by hard working, more deep in thinking and do more research on whatever observed, one day, all human will eventually no longer differentiate each other using mentality.

As for japanese robotics, i can only say, robotics is not a precise measurement of mentality level. Country such as China, Korean and India may also eventually play a role in such field. Real technology that human need is come up with something that harm the earth less and also explore to outer space. There is still a lot theory need to be studied and improved.

I can only say, the more we learn and understand, the more we dont judge people by mentality. There are always some reason for some one to become like what you see. If one feel the other one is low in mentality, he/she should provide more help and lead the person to the right direction then just simply give a comment.

if i lose power, i get upped voltage. isit possible to convert that amount of voltage to energy?

That doesnt mean that energy is up.

The transformer never adds any energy to a system.In fact ,you lose some energy to eddy currents and heat.

It's always losing energy.

Transformer is simply a device that transform voltage by means of magnetic field induction. When a high voltage is produce from low voltage, it is equivalent to reduction of current so as to comply with the facts that energy is always conserved. In reality, energy seems not conserved or loss because there is always a leakage path for an energy to escape/leave of the system. As for transformer is concerned, losses due to leakage of magnetic field and also due to the winding resistance.

As for make a smaller joule to create, a bigger joule, it can only be achieve as long as the principle of energy conservation is obeyed. For example, those solar water heater manage to use less electric energy to heat up more water by absorbing heat from the sun and also environment. The only possible way to get smaller joule to create bigger joule is to absorb stray energy in the ambient, including widely known wireless energy.

Rather than trying to solve this problem, shouldn't we find other pratical energy sources or make things more efficient?

Voltage cannot be converted. In an analogous way of saying, its just like gravity, just that the 'mass' is charge. And charge is in the current.

Its in the very same formula you provided us with. You will still get the same amount of power/energy with either 1 megaV and 1 microA, or 1 microV and 1megaA. No you can never increase volts without reducing current and vice versa without adding your own energy.

Thanks for the enlightenment. Never knew giving a stupid statement can learn so much in return

There's no way to create additional energy from nothing. In your example of a solar heater, you are using the solar power along with the electrical power to heat up water. The total power output of the heater will not exceed the power provided by the sun and the electrical outlet. The only thing that this setup can reduce is the amount of electricity used in heating the water. So how can you say that you can get additional energy from a fixed amount of energy? You are excluding the secondary energy source(solar energy) from the equation when calculating the total power provided to your water heating system.
