Question by Jose: Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen?
Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen reacts with oxygen to produce water, and at the same time, it releases a great deal of energy. Write an essay that addresses the chemical reaction of hydrogen fuel cells, the energy that is available from this reaction, and whether this type of alternative fuel is feasible. Be complete and use examples to support your statements

Talk about the possiblities of space travel because of hydrogen fuel. Talk about the possibilites for cars powered by water! Just talk about really neat things that can be done with hydrogen power.

Preserving nerve cells in motor neuron disease
A team of researchers, led by Scott Oakes, at the University of California, San Francisco, has identified a way to prevent symptom onset, weight loss, and paralysis and extend survival in a mouse model of amyotrophic lateral sclerosis (ALS; also known as Lou Gehrig’s disease), providing a new avenue of research for the development of therapeutics for ALS and other motor neuron diseases.

Question by ME: Would it be possible to power an energy star light bulb using the light it produces and photo-voltaic cells?
Follow-up. Say you have a lightbulb on a seperate power source shining its light on a single photovoltaic cell. If you added a second cell to the first, does that multiply the output x2, exponetially, or only slightly? I guess my question is does the amount of power generated by photocells depend on the strength of the light source or just the number of cells?

Best answer:

Answer by ioerr
No you can’t power a light bulb this way.

Even if you completely surrounded the light bulb with photovoltaic cells, their combined output still would be less than what the bulb takes to create the light they’re capturing.

The power in the light that the bulb creates is itself less than the power the bulb requires to make that light. In other words, the bulb is not 100% efficient at turning power into light. No bulb is, or can be.

Likewise, the cells are not 100% efficient at turning the light they capture into power, far from it. And no cell can be.

Likewise, even the wires in the circuits involved are not 100% efficient at transmitting the power from one end of their lengths to the other.

No real machine is 100% efficient at converting power to work, or ever will be.

The law of physics that deals with this is called the conservation of energy. It just means, there’s only so much energy in a system. You can’t create or destroy it, you can only change it from one form to another. In order to power the bulb with the output from a cell capturing light from it, energy would have to be created that wasn’t originally in the system. This would violate the law of conservation of energy.

This is why perpetual motion machines are impossible.

As for the 2nd question, the output goes up arithmetically with the number of cells. 2 cells put out 2x the power, 3 put out 3x the power and so on. As long as the light on each is equal. Yeah the brightness of the light makes a difference too. But in every case the total output will still always be less than the energy required to create the light they’re converting.

when I was younger, I used to think that Nuclear Power Plants used nuclear material to collect electrons, but now I know that it’s only the heat given off that creates steam which turns a turbine.
HOW LAME!

Why can’t we use nuclear material to create electricity directly?
Or maybe even replace electrons altogehter.. replace the electrons with some other charged particle that repells objects similar to magnatism, maybe then we will no longer need copper wire???? If we could find an alternative to electrons and have repulsion properties, we could re-invent the electric motor, make it so that it works directly from nuclear material??
Guys! go see

I am doing a physics experiment where I need to compare the efficiency of the two. Solar panel for radiation>heat water and solar cells for radiation>electrical energy.

Can anyone recommend me some cells and panels which have lots of information about their performance, efficiency etc?

Many thanks!

An antique automobile bumper is to be chrome plated. The bumper, which is dipped into an acidic Cr2O72- solution, serves as a cathode of an electrolytic cell. The atomic mass of Cr is 51.996; 1 faraday = 96,485 coulombs. If oxidation of H2O occurs at the anode, how many moles of oxygen gas will evolve for every 1.00 x 102 grams of Cr(s) deposited?

How do you set this problem up? Any help would be great thanks!

Hydrogen generators come in all sizes and shapes and we at LaBellas Auto Repair have been investigating, reviewing and comparing the output of HHO fuel cells of various kinds. Weve found that some of the smaller fuel cells put out more hydrogen gas than some of the fuel cells that are 3 times larger than their smaller counterparts. Our investigation to date has cost over $6000.00 and weve found that some of the more hyped up larger hydrogen fuel cells are a waste of money. Especially ones that use vinegar ( 5% distilled vinegar like used on salads). The rat race for whos has the best HHO fuel cell still rages on with some of the most outrageous claims uncovered. The hydrogen fuel cell in this video used vinegar but hardly put out any HHO gas until we switched it to KOH potassium hydroxide. The smaller twin fuel cell we earlier demonstrated put out much more than this larger fuel cell at comparable amp draw. See this live video.

Commercial electrolytic cells for producing aluminum operate at 5 volts and 100,000 Amperes. How long does it take to produce 1000 kilograms of aluminum? If electricity costs 9 cents per kilowatt hour, what is the cost of producing exactly 1 pound of aluminum?
