Biotech for food, fuel
Bioengineer: Corn to ethanol is wrong conversion
At the GoingGreen conference in Sausalito, Calif., J. Craig Venter says going from food to fuel–corn to ethanol–is taking resources in the wrong direction. He discusses oil palm and the jatropha genome as future fuel possibilities, and talks about algae as a way to convert carbon back into a useful chemical.
solar and wind power solutions are on the minds of a lot of people these days with energy costs soaring and the threat of global warming hitting close to home. Solar and wind power solutions can not only save you a great deal of money on your energy bills but can also help in the effort to save the environment.
Can you afford solar and wind power solutions for your home? It could cost tens of thousands of dollars to completely convert your home to solar and wind power solutions. Of course a complete conversion would pay for itself over the many years you will live in the home without having to pay another energy bill.
If you can’t afford a conversion to solar and wind power solutions, perhaps you can afford to start small and save a portion of your energy bills. If you are a mechanical person, you can even build solar panels and wind power turbines by yourself and save an enormous amount of money. Do it yourself solar and wind power solutions aren’t for just everybody, though. Many people don’t have the time or the aptitude to do it.
You can purchase a small, portable solar panel that would be enough to power a computer and a few lights and small appliances for under $1,000. These are a wonderful solution for campers and boats, and they can be used at home, too.
A small wind turbine that would create enough energy to save more than 50% off of your electric bills would cost about $1,000 as well. Most residential homes need anywhere from one to five Kw of power from a wind turbine, and they need to be in a location where there is plenty of wind, on average at about 12 mph.
Of course the prices of these solar and wind power solutions will vary depending on where you live and how much power you actually want to get from them, but they are roughly what you can expect to find. The prices may even be significantly less in an area where solar and wind power solutions have already surfaced and there are several dealers in the area, or significantly more if you are the first in your area to buy solar and wind power solutions.
If you want to make your own solar or/and wind power generator and generate free electricity. Check out my blog: http://www.make-a-windmill-generator.com/ It's best way to save energy and money.
You can build your own solar power panel or windmill for less than $200 with Earth4energy!
With the advent of solar and wind power consumers are changing the way they look at powering their homes. Instead of using polluting fossil fuels, many environmentally conscious people are turning to these clean and renewable energy sources to power their homes and businesses. In this article, we'll detail how wind and solar energy works and how these systems can save you money.
By converting kinetic energy into mechanical power wind turbines it can then run a generator to produce clean electricity. There are several things that you should keep in mind if you intend to invest in wind and solar energy. Firstly, your property must have a good wind resource and you will have to check with your local government to make sure that tall towers are allowed in your area.
It is a fact that wind energy systems are one of the most cost-effective method for home-based renewable energy . Depending on your wind resources, a small wind energy system can lower your electricity bill by 50% to 90% and help you avoid the high costs of having utility power lines extended to remote locations, prevent power interruptions and pollution.
Radiant barrier is a relatively new product that consumers are slowly becoming aware of. It consists of a reflective composition placed in your attic that reflects heat before it enters your home. Our government, universities as well as independent laboratories have tested this new energy saving product and it works. People seem to have a hard time believing that their attic can be converted into a giant mirror reflecting heat from underneath their roof. By applying just a coat of paint under the decking surface it will reduce heat transfer and insects by sealing up cracks and crevices.
Roof temperatures can rise to almost 200 degrees. Attic temperature can be as hot as 140 degrees. This heat creates moisture that falls to your attic floor on your insulation. This causes your insulation not to work properly and lowers the insulation value. Radiant barrier works three-fold by reflecting heat from your home, lowering the temperature in your attic that allows your insulation to work more effectively and this causes your A/C unit to work less. An additional benefit is that you’re A/C ductwork lasts longer because it isn’t exposed to such high temperatures that induce drying and cracking creating air leaks.
Plug-n-play solar chargers have recently come on the market, putting solar power within the reach of just about anyone. You no longer have to be tech savvy in order to harness solar energy.
You can find out about the specific types of Plug 'n Play solar chargers available, and where to find them, at Plug n Play Solar Chargers
But what exactly is a plug-n-play solar charger? In its simplicity, it's usually a solar panel combined with a battery pack, sold as a unit, which is capable of collecting solar energy and storing it in a battery. That's all there is to it.
The feature that makes this type of set-up so useful is that you can use it to power or recharge your electrical devices, laptops, power tools, radios or even TVs, from the battery pack. The solar power and battery pack are sold together, so you don't have to worry about compatibility, cables, watts or voltages, or any of that. And you don't have to wonder whether the setup will work or not.
By using the battery pack, instead of trying to power your equipment directly from a solar panel, you ensure that you have a steady flow of power or electricity flowing into your equipment. Even on a sunny day there can always be a few clouds. When they move in front of the sun it there would be a decrease of solar energy being picked up by the panels, which would momentarily reduce the amount of electricity being produced by your solar charger. But if your equipment is connected to a battery pack (which is in turn connected to a solar panel) the battery would take up the momentary slack in solar energy.
