Gas Generators
A wide variety of fuels are used to power generators. The most common are gasoline, diesel, propane and natural gas. With such a wide array of options, the house owner's choice of fuel and the right type of generator will depend upon factors such as the availability of fuel and the frequency of the use.
Gasoline generators
Gasoline generators are the most familiar type of generator. The fuel is readily available and is relatively inexpensive. The power per weight unit in a gasoline-powered generator is also more than other type of generators.
Gasoline generators are less expensive than generators that use other fuel sources. However their price depends upon the components used. Multi cylinder, water-cooled engines are qualitatively superior and are priced high. These generators, unlike the cheaper, single cylinder, air cooled engines produce less noise and operate with a steady temperature. Some generators come loaded with features like overhead valves, low oil shut down, high temperature shutdown and electric starter.
Engine speed and the type of alternators used also determine the life of the generator
There are certain disadvantages using gasoline generators. Gasoline has a very short shelf life of approximately six months. Fuel stabilizers have to be added to keep the fuel from getting unusable. Gasoline is highly inflammable and storing gasoline for long duration of time can be extremely dangerous. Gasoline generators require frequent maintenance and there is the problem of condensation occurring in cold weather.
Gasoline forms gum deposits especially in cold weather and can cause problems in fuel filters and carburetors if the generator is not run often.
The generators are available in 3KW to 15KW and more. The minimum cost of home generators in the range of 3KW to 5 KW is approximately $500 to $1000.
Natural gas generators
Most standby or permanent generators are powered by natural gas. It is the most convenient source of fuel and normally available at all times.
Natural gas supplied through home gas lines can be conveniently piped to the generator eliminating the inconvenience of refueling and the risk of storing the fuel. In areas where natural gas is available, using a natural gas fuelled generator is a better choice. The generator lasts longer, requires less maintenance and burns cleaner. The engine produces less noise than diesel or gasoline powered generators
Propane gas generator
Propane gas is normally used for permanent standby generators or in places where there is an availability of fuel supply. For house owners who already have a storage tank of around 150 to 200 gallons, propane generators are the best choice.
These generators require less maintenance. There is no problem starting them up or condensation in cold weather. Propane gas has a longer shelf life and burns cleaner. The disadvantage of propane is that it is relatively expensive and is less efficient, producing less energy per unit volume than diesel. A 10KW to 12KW generator is sufficient to power a normal sized home.
A 12KW propane or natural gas generator may costs $3200 upwards. .
Diesel Generators provides detailed information on generators, diesel generators, electric generators, emergency generators and more. Diesel Generators is affiliated with Carbon Block Water Filters.Generators
Generators are used for the generation of electric power. There are basically two types of generators: standby generators and portable generators. Generators ensure that most of the essential appliances can be run whenever there is a power outage. Standby generators provide backup power in homes and offices and are permanently installed outside the house or office building. They are plugged into the electric circuits or home wiring.
Standby generators can automatically detect disruption in the usual electric supply and begin supplying power within a few seconds. Portable generators are usually used in places where there is no supply of power or the need for power is less such as on construction sites camps. These generators are sufficient for lighting and to run appliances like televisions, refrigerators, sump pumps and furnaces.
Generators are available in varying size and output power. The choice of buying the right type of generator depends upon a number of factors...

Diesel Generators
Fuels such as gasoline, diesel, propane or natural gas basically power home generators. Some models also have multi fuel capabilities and run on gasoline, propane or natural gas. The choice of the fuel will depend on the availability of the fuel in times of emergency, fuel consumed per kilowatt of power produced, maintenance of the generator and the comparative risk of storing the fuels.
Diesel generators consume comparatively less fuel per kilowatt of electricity produced and more fuel-efficient than generators powered by natural gas or gasoline. For every gallon of fuel consumed, diesel generators run 2 or 3 times longer than gasoline engines. Diesel generators do not require frequent maintenance, as is the case with gasoline generators and are designed to run continuously for long hours.
Most generators come with a water-cooled engine with a speed of 1800rpm. This ensures the engines durability, and at the same time, makes it the most dependable of all the other...

Launch of new Long-range Electric bike
Up until now, most Electric Bikes were limited in range to 15 miles. The Koolgachet e-cycle, changes this forever.1.???The battery is 36v 12Ah has an incredible range of 40-45km.2.???The bike has superb styling and has a lightweight aluminium-folding frame.3.???The Mick Sport breaks a new price barrier of ?550 for a quality folding electric bike.Electric Bikes Direct was formed to address this issue, by supplying to the UK public a range of superior Folding, Lightweight, Electric Bikes.We supply a range of bikes that meet a few, but essential criteria: -????Practical and stylish. All our bikes have folding frames, they fold in around 15 to 20 seconds; they can then be stowed in their own storage bag, under the desk, in the caravan, on a boat, on the train and always in the boot.????They all allow you to get some exercise and enjoy cycling with as much effort as you decide. (In a recent survey Electric Bike owners were getting more exercise than conventional bike owners, as they were...

Portable Generators
Portable generators are used in homes and in places where there is no power or the need for power is minimum. Portable generators are generally smaller and are designed to use for a few. A portable generator of 5KW has enough power to keep lights, refrigerators, computers and televisions running for 7 to 8 hours. Portable generators are normally powered by gasoline, diesel, propane or natural gas. They are the most popular of all portable generators.
Gasoline generators are relatively less expensive but require frequent maintenance and have a shorter life span. Gasoline has a short shelf life and cannot be stored for a long time unless treated with stabilizers.
Diesel generators, on the other hand, are fuel-efficient, consume less fuel per kilowatt of power produced, have longer life and require less maintenance. Diesel can be stored for longer periods of time. However, they are harder to start in cold weather and noisy. Portable generators powered by natural gas...

Electric Generators: Understanding Your Power Needs
In order to choose the right emergency power source and to size it properly, you need to understand something about the power requirements of the devices you plan to operate.
The basic unit of power measurement is the watt, and with an emergency power source there are two wattage ratings that are important: steady-state wattage and surge wattage. A normal 60-watt incandescent light bulb requires, as you would expect, 60 watts, and it requires that wattage both when you turn it on and while it is running. A ceiling fan motor, on the other hand, might require 150 watts to get it started and 75 watts while it is running. That extra wattage to start the motor is called the surge wattage and is typical of anything that contains an electric motor.
Here are the usual wattages of some of the devices found in a typical household:
Device Typical wattage Surge Wattage
Light bulb 60 watts 60 watts surge
Fan 75 watts 150 watts surge
Small black...
