Is A Gasifier The Best Alternate Energy Source?

A gasifyer is a mechanical device for heating wood chips, or many other types of dry organic matter, to a temperature high enough to release the volatile gasses locked within them. The gasses produced can be burned in an engine to make power or merely burned in a heating system. The fundamental structure of the gasifier may be a container perhaps the size of an oil barrel which needs to be well insulated to retain the heat.

The container has within it a layer of burning fuel. This has access to outside air, allowing a small part to burn, but under controlled conditions, and start the gas production.

This makes the whole process self contained.

A modest controlled burn is necessary, partially because you do not want to simply set fire to all the combustion volume, and the small fire burning with limited oxygen is efficient. This warmth is used to dry out and warm the fuel stock, so that when it falls into the fire grate, it will readily burn. Temperatures of the order of 1200 degrees F should be aimed for. These hot volatile gasses ascend naturally and escape at the top of the cylinder. They are then filtered to take out particles, and cooled as a denser gas has more power.

A specific benefit is a gasifyer is it is self contained yet small enough to be moveable by pallet or trailer. A four cylinder engine needs an oil drum sized gas producer, but if the fuel is a waste product, the gas is just as good.

Any combination of chipped wood and or branches, rice or corn husks, shells, pits, animal dung, in fact any waste organic material, could be used. Even fast growing willow might be planted as a fuel harvest.

Using commercial agricultural waste as a fuel will not just save cash, but also monumental amounts of landfill space. The gasifyer residue, or char, is an excellent soil conditioner, making it a very eco-friendly alternative.

My specialty is more with the usage of a gasifyer to trim house hold expenses and or off grid living.

household gasification has the extra advantage of producing gasses, regularly called syngas, that are very clean burning, producing little or no contamination.

The claim is that 20lbs of dry chipped wood is equivalent to 1 gallon of petrol. A suitably sized gasifier could be made to furnish all the gas for a selected engine, the larger the gasifier the bigger the engine. A gasifyer does not necessarily call for any external power although this will help to start the machine, someone will still have to fuel the machine. Once running the inductance from an internal combustion engine will draw air through the hearth, helpfully making it self sustaining.Check Out The Gasifyer.com

As a green alternate energy source a gasifyer and petrol generator offers a serious solution.

How To Save Gas By Hypermiling

Getting your first car can be a real thrill. Finally you have the freedom to go wherever you want, whenever you want and with whomever you want! This newfound freedom is quickly undermined by the realization that you have to pay for your own gas, oil changes, fuel filters, car repairs and auto insurance. While some of these expenses are inevitable, there is one thing you can do; save gas by hypermiling! In this article, you will learn about some of the hypermiling driving techniques motorists are using to save money, without sacrificing their independence on the road.

The first step many hypermilers take is to track their mileage, so they have a clearer understanding of what works best for their vehicles. They can compare how they drive on Monday to how they drive on Tuesday. They can glance down at something called a Scan Gauge to see how many MPG they’re using or even how much money a certain trip cost them in gas. The Scan Gauge isn’t exactly cheap (with a price tag around $160), but the installation is painless. Experts say that being conscious of how accelerating, braking and driving techniques affect your gas mileage can really make an enormous difference and most drivers save an instant 10% of gas this way.

One of the most sacred rules of the road for all hypermilers is to only brake when you have to. While most people are inclined to speed ahead to the stop light and abruptly slow down if the light doesn’t change in time, the conscientious hypermiler will take his foot off the gas as soon as he sees the light is red and will slowly coast up to the intersection. This is also sometimes called “timing the lights” because often the light will change when the hypermiler gets there. Another trick is to take a 10 to 15 second buffer after the light turns green and the other cars accelerate. By leaving extra space ahead, drivers can see the brake lights well in advance and avoid hard braking. Some drivers say they save gas by watching their mileage go up over 70 MPG even while sitting in traffic!

Some people decide to save gas by modifying their cars. Most vehicles out there are not built specifically with gas mileage in mind, so there’s much to be accomplished by making some basic changes to the existing structure. For instance, some hypermilers add something called a “grill block,” which goes over the grill of the car and prevents air resistance (to save about 5% of your overall gas mileage.) This is one of the cheapest and easiest mods to install. To save another 4.5%, you may want to purchase “smooth wheel covers” or “rear wheel skirts” to reduce wind resistance further. The more drastic measures may include removing alternators, swapping engines, changing from automatic-to-manual, or converting to alternative fuel and electric designs. One driver converted her Volkswagen to a corn oil/diesel mod for $3,000. Or, in some cases, it could be as simple as inflating your tires and having your air filter changed every oil change. There are many ways to save!
