Researchers from the  Edinburgh Napier University in Scotland  managed to create a biofuel  for vehicles using the by-products of the distillation process of  whisky . According to the researchers the biofuel could be used to  power conventional vehicles without any particular adaptations. It is worth mentioning that the biofuel was created during a research project that lasted 2 years. The two by-products,  “pot ale” , which is a liquid found in the copper stills, and  “draff” (the spent grains) are used as the basis for creating  butanol . The latter can be used as fuel, reports  Physorg . The lead researcher  Martin Tangney  says:  “The new biofuel is made from biological material which has been already generated” . He also mentioned that the biofuel will most like be used in combination with 10 percent petrol or diesel.  “Five or 10 percent means less oil which would make a big, big difference,”  said Tangney. The new biofuel has already been appreciated by a number of sp

Paul Hanna  is the author of this futuristic vehicle called Energo Racer . The designer was highly inspired by nature and namely marine creatures. He created the shape of the vehicle after studying the  bodies of marine animals  and analyzing these animals move their bodies to swim faster. The vehicle can be built in a way so it would be powered by  several alternative fuels and power sources . For example, it can run on  hydrogen  or be powered by solar energy .

This futuristic parking system was designed by  Jin Yuanbiao, Gang Tang  and  Su Sha  especially for the all-electric vehicle dubbed Solar Coco. Both the car and the parking system boast nice design and eco-friendly features. The round-shaped vehicle has solar panels  mounted on the roof. When parked, the car is lifted by the system up and exposed to direct sunlight. After being lifted, Solar Coco exposes its solar panels to the sun and the whole structure starts resembling sunflower.

During energy transformations, energy can neither be created nor destroyed. However energy can be degraded, that is there is less useful energy after the change than there was before. This is because some of the original energy has been changed into heat or sound and lost to the surroundings. General and credit level equations Useful equations for energy calculations in power stations include: gravitational potential: Ep = mgh kinetic energy: Ek ½mv 2  (credit level only) electrical power: P=IV also, for all forms of energy: E=Pt Calculating efficiency (credit level only) The percentage of total energy output compared to the total input energy is its energy efficiency

In a hydroelectric power station water is stored behind a dam in a reservoir. This water has gravitational potential energy. the water runs down pipes (potential to kinetic energy) to turn the turbine the turbine is connected to a generator to produce electricity (kinetic to electrical energy) At  pumped storage hydroelectric stations  water is pumped back into the reservoir when there are periods of low power demand. This is often when there is excess energy being produced by other power stations. This stores energy and during higher demand periods the water can be allowed to flow back down to produce electricity just like a normal power station. Such a system saves energy and also can be turned on quickly at times of peak demand.

The thermal power plant is a setup for extracting the hidden calorific heat inside the black diamond to be used for setting the electrons in motion i.e. electric current. Read on to find out about his interesting journey of power conversion. Introduction Having learnt about the basic plant layout and site selection of a power plant it is now time to take a look at the overall functioning of the power plant. I suggest that if you haven’t read the first part of this series regarding general layout of a thermal power plant, you take a look at it, especially the accompanying diagram since I am not going to repeat the same diagram here but will explain based on previous article. The Functioning of the Plant The four circuits of the thermal power plant make a complete picture when put together helping to generate electricity out of fuels such as coal which is the most widely used fuel. The calorific value of coals depends on the quality of the coal and the place from where it is mine

I am invariably finding many hits on cooling tower capacity & performance calculation and related queries. Therefore, I have decided to include the detailed calculation procedure in order to enable many students & process engineers who are interested in improving cooling towers performance by following these simple steps. If you have any query, kindly post them in the comments section. I’ll try my level best to answer those queries as soon as possible. First you should collect all the data as given below. Be sure that the data collected for these temperatures is most accurate because of lower absolute level of generally ~40°C average temperatures, an error of 0.5°C due to manual data collection & judgment will cause more than 1.2% error in the result at one calculation. Repeating such errors may result in cumulative errors of more than 10% in totality giving you totally absurd results. So the basic point is that collect the data on regular basis, keep a watch to have

Bio Mass generator – Better burner Bio mass fuelled equipment manufacturer Talbotts has launched what it claims is one of the most efficient wood – fuelled bio mass generators on the market. The BG25 CHP unit believed by TALBOTTS TO BE A WORLD FIRST BECAUSE OF AN INNOVATIONS THAT INCORPORATES AUTOMOTIVE technology to ensure continuous operation on a self-sustaining generating cycle. The system works by burning waste wood in the form of pellets in a combustor waste that generates hot air through a mile and half of piping – packed into a compact heat exchanger. The hot air powers a turbo charger more usually found in Scania trucks. While much of it this heat energy is cycled back through the compressor to charge fresh incoming air and continues to drive the turbocharger, excess energy is captured by a substantial alternator via a specially designed gearbox. The self- contained system generators 25kw of power, and recycles excess energy within it, achieving what Talbotts said, are “un

New Solar Technology To Generate Electricity is almost a cliche these days. Let’s look at some promising old technology. Today, on Engineering Works! Listen to the podcast. When people talk about solar energy, they usually mean one of two things. Photovoltaic panels or solar concentrating plants. Some engineers are trying something else. An updated version of a two-hundred-year-old invention to turn sunlight into electricity. This old technology is something called a Stirling engine. A Scottish clergyman named, you guessed it, Stirling, invented it in 1816. The idea is simple. A Stirling engine has two cylinders and pistons. Kind of like a two-cylinder motorcycle engine. The space above the pistons is filled with a fluid, usually air or helium. Heat the gas in one cylinder and it expands, moving the piston. The gas cools and moves to the other cylinder, where it moves that piston and flows back to the first cylinder, where it’s heated again and the whole cycle starts over. It’s m

leevenspark: Diesel: The Fuel of the Future?

THE GIST OF THE STORY ------------------------------------------------------------------------------------------------------------ A new kind of fuel cell runs on diesel instead of hydrogen. A fist-sized fuel cell produces 250 watts of electricity, enough to power yachts and mobile homes. ------------------------------------------------------------------------------------------------------------   Diesel, a fuel once derided as being too loud and too dirty, could be the key to clean, quiet and more environmentally friendly energy. A Norwegian company, Nordic Power Systems, in conjunction with Cal Tech spin-off SAFCell Inc., recently released a new fist-sized, diesel-powered fuel cell that produces 250 watts of electricity, enough to power yachts or mobile homes. Scaled up, the researchers could use the fuel cells to power even more energy-hungry machines. "Diesel is available most places, is not seen as a hazardous fuel in any way, has high power density, and (our
