Can anyone help me in my project?

i`ve got to make a project on conservation of resources. in that we have got to make a working model and a report.in that we have got topic of rain water harvesting and hydroelectricity.and need more topics to cover under this title`consevation of natural resources`.can give ideas to do this project

Answer 1

No muss, no fuss!

Collect rainwater in a rain barrel you make from a BIG (32 gal or more) trash can -like the ones they sell at Lowes or Home Depot. The best way to do this is to elevate the trash can as high as you can, and feed it with a down spout from the gutter around your roof. Drill a hole in the bottom, and install a "hose bib," which is a simple outdoor faucet with a place to connect a hose at one end, and a threaded piece of pipe on the other. You'll need a big washer and patch of rubber to make this leak proof. These go on the inside of the barrel. Put some acquarium glue on the floor of the barrel around the hole, then the rubber patch (with a hole for the pipe to go through) then more glue, then the big washer, more glue, and then s***w on a short union (which is a threaded piece of pipe used to connect other longer pieces of pipe.  s***w the whole thing together tightly to pinch down on the washer, rubber and plastic body of the trash can.

If the rain water has junk in it, such as leaves and sticks from the gutter, you'll need a filter to catch this and let the water go through. Make a basket of 1/4" hardware cloth mounted below the end of the down spout. Make it as wide you can, and about 6" deep, and suspend it with coat hanger wire from the top of the trash can. After it rains, you can remove the basket and dump the accumulated debris.

As a last step, cut a hole in the lid where the downspout will go.

If that's all to complicated, forget the hose bib and just remove water either by dipping with a pail or using a short section of hose as a siphon.

Now, what can you do with the water? Wash a car, water a garden, flush toilets, just about anything except drinking the water. Keep the lid on to control mosquitos.

Now, get a copy of your last water bill, or, if you are on a well, calculate the cost of running the pump (people at the electric company can help you figure this out) PLUS the cost of replacing the pump to get a cost for depreciation. What you want is a cost per gallon. Take that times the number of gallons in your can -and there's your savings! Doesn't seem like much, maybe, for just YOUR house, but mutliply it by all the houses in your neighborhood and you'll see the number grow.

As an extension of the project, consider making "compost tea." This is done by saving grass clippings, shredded leaves (shred them with a mower or leaf vacuum) and vegetable matter from the kitchen (onion skins, peelings, etc.). These need to be stored in a wire cage you mount over a big wash tub. The wire can be 3 or 4 foot wide "rabbit wire" which looks like rectanagles of about 2" by 4". The cage should be as big around as the tub, with the bottom made of hardware cloth. You can cut off the last edge wire of the rabbitt fence and bend the remaing wire sections to hold the hardware cloth bottom. The cage should sit on a platform over the tub; the platfrom can be made of pieces of wood big enough to keep the bottom from falling out, but with space between the wood to let water come through. You can actually put cinder blocks around the tub, then lay the wood sections across so they hold the cage above the tub. You need enough room to pull the tub out from under the platform. To secure the sides of the cage, you can use metal stakes driven into the ground.

Load your cage with the clippings, leaves and kitchen scraps (but NO meat or grease). Stuff everything in tightly, and add to it as the mass collapses. Now add water from your rain barrel. After a while, water will begin dripping into the wash tub. Keep adding water from time to time, so a few quarts drain through every day. To make everything work faster, cover the whole apparatus with a black material so it gets hot inside. Use the tea as fertilizer for your garden. Control mosquitos using a small piece of a "mosquito dunk," which you can find at Lowes or Home Depot (pest control shelf in the garden section). The dunks are not good for you to eat, but the very small amount in the tea won't hurt when put on the garden.

Have a good time!

Answer 3

In agriculture, the term contour plowing refers to creating furrows and plantings that follow the contour of the terrain.  This strategy allows rain water to drain into the soil instead of running down any hill or incline thus saving water, fertilizer and the plants themselves.

Answer 4

Hi,

You might look at these to get some ideas:

Renewable energy related student projects:

http://www.builditsolar.com/Projects/Edu...

A number of these involve building models to demonstrate renewable and solar energy concepts.  Some of them look like a lot of fun :)

Small Hydro:

http://www.builditsolar.com/Projects/Hyd...

Information on building household size mini-hydro genererating systems.

Water Harvesting:

http://www.builditsolar.com/Projects/Wat...

These are home scale, mostly build it yourself, size systems for harvesting rainwater from roofs (and other water conservation related material).  You could easily do a model of one of these systems.

For other home scale solar heating, solar electricity, solar cooking, ... ideas, have a look here:

If you come up with a good project and model, take some pictures and send them into www.BuildItSolar.com, and I'll publish it on the student projects page.

Well some teachers gives people a project just to go and make more research and meet someone to help. you go to www.en.wikipedia.org and ask in the link. The site is the best to answer question concerning project. Just try and It will be of a help
