Why To Use Solar Christmas Lights To Decorate Your House

Christmas is the one season that almost everybody enjoys. It is a time when we can forget about the darkness and cold that is outdoors and instead share happy moments with our loved ones. Even the act of putting up Christmas decorations can bring us all a degree of joy. Most people are now aware that the cost of electricity is more expensive than it has ever been. But it is now possible to use solar Christmas lights so that your energy bills will not rise. This option is becoming more and more popular every year with families around the country.

These solar lights appear the same as ordinary Christmas lights. In fact the only difference is that you do not have to connect them to the power supply of your home. They come with solar cells and a battery which are used to power the bulbs and LEDs.

You may think that in winter the sun does not shine enough to provide power for solar lighting, but today’s solar cells can function even on a cloudy day. As the energy is stored in one or two batteries the lights will shine brightly throughout the night.

Apart from the obvious financial savings that are had by using this renewable source of energy, another important factor is that you know that you are not contributing to environmental problems.

As with the old fashioned Christmas lights, the solar Christmas lights can be bought in many different sizes, designs, styles, and colors. There are some that can be continuously on and others that will switch on and off to give a flickering appearance. Usually the controller board has settings so that you can choose when they will turn themselves on and for how long.

Most brands can be safely used both indoors and outdoors. They are capable of working in any weather and conditions. They look perfect when they are attached to trees, porches, guttering, and garden accessories. If you choose to use them inside your house you must remember to leave the solar cell outdoors! You can even use them for other occasions such as birthday parties.

Generally, solar Christmas lights come in two different forms – rope lights and string lights. Rope lights have a string of LEDs which are contained within a clear plastic tube. These are perfect for hanging around doors and windows. String lights do not have a tube and look magnificent on trees or hanging from a roof. They are a perfect addition to your Christmas decorations.

Magnets 4 Energy – Magnetic Perpetual Motion Machine

Taken literally, the term perpetual motion refers to movement that goes on forever. However, the term more commonly refers to any device or system that perpetually or indefinitely produces more energy than it actually consumes, thus, resulting to a net output of energy for an indefinite period of time.

A Magnetic Perpetual Motion Machine, therefore, is a device that utilizes the properties of a magnet to produce energy. Magnets have north and south poles which will attract and repel. The fundamental law of magnets is that opposite poles attract and like poles repel. This machine uses three magnets, one of which pulls the different sides of the other two. These repelling and attracting forces generate rotational motion inside an electric magnet motor, and will generate power without ever stopping. This machine can run up to 400 years, and we all know that no individual can live that long, thus, the term perpetual motion machine.

A magnetic perpetual motion machine is growing popular as an alternative for power source by converting energy into electricity. It is so powerful that it can power up to 7,000 watts. It can provide energy to an entire house, and can even produce more power than you will actually need.

Using magnets to produce energy may prove beneficial to mankind because it is cost-effective and it is eco-friendly. At present, the world is concerned about energy security, global warming, and fossil fuel depletion. The human population has grown to such a tremendous number and is still growing that soon, mankind will consume more and more energy than the earth can actually supply us with. There will come a time that this planet will no longer be able to sustain what we need in terms of power.

By using magnets to produce energy, we do not depend on fossil fuels. Thus, we are able to conserve those non-renewable energy sources, and we are able to preserve our planet as well.

Solar Oven Designs – Using The Sun To Heat Your Food

In most 3rd world places, where electricity and other fuel sources are hard to come by, solar oven designs have been used. Not only are they effective in cooking food, but also for water purification in sunny countries like Sudan.

But just because first world countries have enough energy supplies, it does not excuse us from using solar cooking at home and helping to conserve that energy. What’s great about solar cooking is that it uses the power of the sun to cook food – though it may take 4 times longer than a conventional oven.

There have been a variety of unique solar oven designs thought up, but they can be categorized in three shapes: parabolic, panel, and box cookers.

Parabolic Shape:

A parabolic solar cooker, as the name implies, is made from any reflective material in a parabolic (bowl like) shape that focuses sunlight to a single point. It is the most effective at cooking food quickly and efficiently, however, it tends to be more expensive and hard to make by hand. Furthermore, its fixed shape makes it less portable and raises some safety concerns.

Panel Cooker:

Similar to the parabolic design, the panel design focuses sunlight to a single point. However, it is less rounded and made up of a number of small, flat, reflective panels.

Although not as effective as a parabolic cooker, it is safer, easier to make, and can be folded up for portability. Panel cookers come in a number of innovative designs, the simplest being made from a fold-able, reflective windshield shade.

Box Shape:

Very different to the other two designs, the box cooker works by trapping the sun’s heat, instead of simply focusing it on a central point. It is designed in such a way that it let’s light in, but stops that heat from escaping. As more sunlight comes in, the hotter it gets.

This results in the entire area of the box to get hot and be able to cook larger portions of food at a time. This design is by far the simplest to put together – all you need is a black cardboard box with one side covered in tin foil and a sheet of clear perspex or glass on top to hold in the heat.

In fact most of these solar oven designs can be made from household materials in a short space of time. And what you can cook in them is really limited to your imagination – you can bake bread, steam vegetables, make stir-fries and even a roast chicken in them. Another advantage is the amount of power you’ll save – unlike a conventional oven, your cooker needs to be outside to operate, so it put less strain on your kitchen’s air conditioning system.

To think that – according to the Residential Energy Consumption Survey – almost 75% of Americans prepare at least one hot meal at home per day, 33% prepare two or more, a large amount of electricity can be saved if more of us try solar oven design at home.

So get started cooking with solar today. There are a number of commercially available solar cookers on the market. Alternatively you can make your own at home by searching online, where a variety of free solar oven designs with full building instructions are provided.
