can you give me an introduction on how to make electricity from fruits?

A simple voltaic device can be made with a piece of fruit and 2 pieces of dissimilar metals.  It won't run your house even if you have lots of them.  The juice serves only as the electrolyte, not the energy source.\n\nFor real power, you'd need to ferment and distil the juice and put it in a fuel cell.  There's lots of fuel cell info online.

All you need to do is add the power requirements of all the equipment you will use, not forgetting things such as lighting, air conditioning, extractors, fans, drinks or food dispensers, water or any other heaters, office equipment (computers, fax machines, copiers etc.) \n\nThen speak to you electricity supply company and discuss it with them.

It is used to generate electricity.

Hmm...  If I remember the physics right, it goes like this: Take two parts hydrogen and one part oxygen and mix them in a chamber with a catalyst and a proton exchange membrane and you get water and electricity.

Pickles conduct electricity (and will glow like a light bulb when a current passes through them!) but I remember seeing on Mythbusters a method of creating a battery that was used in the ancient times and is relatively simple to make.\n\nEdit to your add. details: perhaps if you were to give a complete idea as to what you were doing that involves drawing electricity, magnets, and having to function as a remote control, some of us might be able to point in the right direction. Myself, I'm not sure exactly what you need.

Here are some fun and A+ ideas.\n\n1. Can solar energy be used to cook food? (You will build or buy a solar oven and see if it is possible to cook hot dogs. Simple and really is A+ material. Trust me, that's what I got on it!)\n\n2. What are all the microscopic things found on one strand of human hair? (Test a strand of your hair, someone else's hair and more under a microscope. Easy, simple, and informing.)\n\n3. What ingredients help plants grow? (Test different soil and items to see what makes plants grow the most affectively. Easy and fun.)

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!

A method for making really cheap solarcells from sand and a way to transport the elctricity the generate without any loss. The amount of energy that falls on the Sahara during a year could cover the worlds entire energy needs 50 times over even using standard photocells that convert only a few percent of the light to electricity. With such an abundant and cheap energy source we could replace ALL other energysources as electricity can be converted to any other form of energy and fuel. We could even keep gasoline cars because gasoline could be manufactured from CO2 (from the air) and hydrogen (from water). There would be alot less pollution if I could invent these things.

The cheapest PRACTICAL way of using solar energy at home is to make a solar cooker. \n\nThis is not a solar 'oven' with a big lens or mirror that broils things, it is a box painted black that gets hot as it sits out in the sun the same way your car does. They only cost a few bucks to make and they WORK! I made one and it works!\n\nYou will need two cardboard boxes that fit inside each other, some black paint, aluminum foil, glue or tape and a plastic oven- roasting bag like for a Thanksgiving turkey.\n\nIt is a slow cooker. You can't burn anything in it, because it only gets up to about 320 degrees F. in it. The beauty of it is that it saves you energy (and money) two ways: first, you don't need to run your stove on a sunny day to cook. Second, you don't need to run your air conditioning extra because you didn't heat up the house with the stove on!\n\nSearch on solar cookers. You will find sites with plans and step by step directions. Have fun!\n\nPS. Beckee, I have to admit, your idea is the cheapest and the easiest. I forgot!

If you're talking about the fruit "currant," why are you asking about it in the Physics section?  If you're talking about electric "current," I would suggest not eating it.

Electricity doesn't exactly do work.  Electricity is a form of energy that enables other things to do work.  Like food in your body.  Your body does the work, the food provides the energy.  Electricity is one form of stored energy that is extracted from a number of different sources, like coal, oil, the sun, flowing water, or splitting atoms.

If you are into electrochemistry you could make your own solar cell or a flat panel solar cell. A solar cell is a device for converting energy from the sun into electricity. This project is fairly easy and there are plenty of pics to show you exactly how its done. \n\nAlso read the first source listed first because it tells you things you need to know for the second experiment.

There are many ways to take advantage of the energy produced by the sun.  A good place to start is with a passive solar energy water heater.  They are inexpensive to install and easy to maintain.  The simplest ones use the radiant energy of the sun and convert that to thermal energy using a material that absorbs the light instead of reflecting it, in layman's terms, something black.  \n\nPhotovoltaic (solar cell) systems convert sunlight directly into electricity. A solar or Photovoltaic cell consists of semiconducting material that absorbs the sunlight. The solar energy knocks electrons loose from their atoms in a semiconductor, allowing the electrons to flow through the material to produce electricity.\n\nFor a more in-depth explanation of photovoltaic technology try this site.

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/

electricity or power obtained from moving water\nmainly from dams and tide power plants

If you want me to use those specific terms it sounds like you're going to just copy what I write for your assignment.  I'd be happy to explain the process to you, by I'm not going to write your homework paper.\n\nThe idea is that plants produce food using energy from the sun, and all other life either directly eats plants or eats things that eat plants.  So all life (except some protists, that, like plants, can make their own food) lives on energy that the plants have harvested from the sun.\n\nI hope you already know what the laws of thermodynamics, photosynthesis, and respiration are.  If not, pay more attention in class or look them up on Wikipedia.  You should be able to figure out how to phrase the explaination in a way that uses those terms on your own.
