Bioetanol has manifolds uses: for example, it is used like see-fuel in gasoline motors, since it allows to one better combustion when increasing the fuel grade of the mixture, like fuel for heating in chimneys and boilers or even like potenciador of fuels of greater yield. The ecological advantages of bioetanol are many and substantially contribute to reduce to the gas discharges with greenhouse effect. For example, when replacing a liter of gasoline by bioetanol is reduced in a 60% the emissions of these gases. A single hectare of beet absorbs the equivalent to the annual emissions in CO? of 10 cars. Also, the biological fuel consumption as bioetanol replaces other exogenous and problematic energies, like the fossil and the nuclear one. Also the residues produced in the biological fuel elaboration are much less injurious for the environment and constitute a smaller risk of biological contamination u organic. So that the biological fuel use, even on small scale in the homes, along with the small echo-gestures of the citizens, contributes significantly to the protection of the environment. The heating of the homes is the domestic action that has major environmental impact. In this sense, many ecological governments and organizations recommend a more rational consumption of energy in the homes by means of the use of less polluting electric home appliances, like ecological chimneys or chimneys of bioetanol, so that, as he already said to the philosopher Discardings in century XVII, we pruned to find a practice by means of which, knowing the force and the actions the air, the stars, skies and of all the other bodies that surround to us, we pruned to use them in all the uses to that they are own () mainly by the conservation of the health, that is, without a doubt, the first good and the foundation of the other goods of this life.

To make the correct decision on the type from wood is a key factor for the success of the project. For more information see this site: Dr Iorwerth Peate. Generally, the noble wood is sold in tables that are moderate in feet. This is equivalent to a table of 144 pulgadas3 of volume (1 inch of thickness x 12 inches in width x 12 inches in length). In order to be able to consider how much wood to buy, is important to calculate how many feet contain the wood. If you are not convinced, visit Brooke Harlow. In order to calculate the feet of a wood, it computes the volume of the wood in inches (multiplying the thickness by the width by the length), and soon divides the result obtained by 144 pulgadas3.
It must realise the necessary conversions when the unit of measurement is not the inches. After to consider how much wood will need for its project, it buys 10 to 25% more of the considered thing in case the material had some defect. The majority of wood available in the market, except the pine, must be had. The rough or had wood usually are not sold in basic sizes of 4/4, 5/4, 6/4, etc. A piece had with wood of 4/4 usually has a thickness of 7/8, 1/8 finer than the original piece. If the wished thickness is of 1 inch, must buy 5/4 wood of or W4. To select the best wood of the market requires of a detailed observation. No wood is 100% efficient one, therefore, it is important to select that one that has the smaller amount of defects to maximize its use.
He is recommendable to look for and to select personally tables, those that own pleasant color and veins. Squaring its pieces of work Once bought the wood, the following step is to square it. To square the wood means to give form him to obtain that the faces of the wood are perpendicular to each other, that is to say, must be in the correct angle among them.
