Hybrid Electric Engines.

Thursday, July 29th, 2010

Have you ever asked yourself about hybrid cars? They definitely look stylish and modern, but what is it about them that makes them so different and so special? After all, most cars look the same these days, do they not? They are all designed by computer to be aerodynamic and aerodynamic is aerodynamic, so they all end up looking impossible to tell apart to anyone who is not an aficionado.

Well, the fact is that the difference between a hybrid car and a standard car lies under the bonnet. There are various types of hybrid vehicles as well, but the most common sort has a hybrid electric engine. Therefore, you could say that what makes hybrid cars special from most other, normal cars is their engine.

Or engines really, because hybrid electric cars basically have two engines. One, the internal combustion engine, runs on petrol, LPG or diesel and the other, the electric motor, runs off electricity stored in an array of powerful batteries. On the other hand, ordinary cars only have an internal combustion engine. It is a good idea to examine these two types of engine separately.

First of all the electric motor. Electrical energy is created by several components on the car and stored in a large bank or array of heavy-duty batteries. The electricity is generated by the turning of the internal combustion engine, just as with a normal car, when it is in use, but also by the wheels or / and the car’s braking system. Different models have different methods of creating this electricity, but they are all very hi-tech and very effective.

When the car’s internal computers decide that the car no longer needs the power of the internal combustion engine, it will turn it off and switch to the electric motor instead. The circumstances where this might happen are, for example, when you are driving slowly in inner-city traffic, when you are cruising at moderate speed on a flat motorway or when you are going down hill. This saves a considerable amount of fuel, which is clearly a great saving to you.

However, there are occasions when you have to have more power than the batteries can supply you, for example, when accelerating hard, when overtaking or when climbing a hill. At times such as these, the electric motor will close down and the combustion engine will take over and start supplying power to the accelerator and electricity to the batteries. When the requirement for extra power has ceased, the batteries will take over again.

These choices are all taken by the hybrid electric vehicle’s (HEV’s) on board computer system and you will not notice much other that a rush of power or a quietening of the propulsion system. This works very well in most scenarios, but some drivers of HEV’s would like to have a manual override for abnormal circumstances, such as an undulating terrain.

All in all, cars with hybrid electric engines work very well at reducing fuel bills but they are still too dear to be much more than a gimmicky toy and a salve to the conscience for the rich.

Calendars – Why They Can Be Out

Wednesday, July 28th, 2010

Thousands of years ago, ancient Greek astronomers calculated that the track of the Earth’s axis is constantly, even if in a very slow way, shifting in a uniform pattern. The change is very similar to the manner a spinning top slowly leans one way and then another as it slows down. It is a wobble that occurs as its axis changes direction.

This odd movement of the planet is due to a couple of factors, the most important of which is something called ‘precession’. Precession arises from the fact that the Earth is not a perfect sphere. It is in fact about twenty-seven miles longer around the Equator that it is around the Poles. The Earth then is oblate, or fat around the middle like middle-aged spread, but it is due to the rotation not to its age.

If you imagine the Earth with its Poles off centre. Then rotate that image and you will find that any point, except the very centre of the axis, will move in a circle. But very, very slowly. So slowly that it takes 26,000 years to go full circle and get back to where it started from.

This point then, any point you choose, is very gradually shifting its location in relation to the stars because the axis is gyrating too. The result of this is that, what we call the North Star (formally known as Polaris, which is in fact one degree off true North) will not be over our North Pole one day. In fact, by about 15,000 AD, Vega will be almost above the North Pole, although it will be about four degrees off true North. But even this will not endure, and by 28,000 AD, Polaris will be back above where it is nowadays.

One of the effects of the precession is that seasons vary. They modify the dates that they occur, so that Summer could come earlier or later. The amazing thing about our calendar is that it is corrected for that (with the leap year). If it were not, the vernal or Spring equinox would move over 13,000 years from March 21st to September 21st., which is the date of the autumnal equinox, precisely half a year later.

It is for this reason that the precession of the Earth is generally referred to as the “Precession of the Equinoxes”. Although the precession of the equinoxes is very slow, it can be readily observed. The correct year of 325.25 days is the length of time from one vernal equinox to the next vernal equinox, however, it takes 20 minutes and 24 seconds longer for the Sun to appear in precisely the same place with relation to the stars behind it over the same period. This is why accurate star maps have to be stamped with the exact time and date to which they refer.

Why Humans Must Care For Mother Nature?

Tuesday, July 13th, 2010

The ecological crisis is real. These are seriously being discussed. No doubt most of this is a result of human interventions. There are massive oil spills as in Alaska by Exxon in 1989. Toxic wastes from industries are polluting the rivers and ground water. The sea levels are increasing, many islands as Maldives are expecting to go under the sea and so are many islands in the Pacific region. The depletion of ozone layer is permitting the harmful radiation from the sun to reach the earth. This is the result of the emission of green house gases. Global warming is heating up the earth. Many species are getting extinct from desertification and deforestation. Deforestation in the mountains is leading to devastating floods in the plains. Between 17,000 and 100,000 species are reportedly becoming extinct every year. The last 50 years have seen most of the forests estimated at seven million square kilometers have vanished. Just twenty percent of the original forests still remain.

We do know from science that there is a strong inter-relationship between species, and between species and the non-living things in the environment. The survival of the species depends on the extent to which this inter dependence between species, whether micro-organisms, animals or plants, is possible. Ecosystems, scientists say, cannot be engineered and created by humans. It is only by letting the ecosystem survive that species will survive. That is why the importance of conservation and preservation is considered vital. But human progress through development and growth is threatening the survival of species.

The value of conservation can be enhanced if more people begin to appreciate such nature reserves. One way of doing this is by camping in such reserves responsibly. A camping tent comes in as essential equipment. You will have to select a suitable tent. Kelty Green River 4 tent is a two season for four people and is more of a base camp tent. There are tents to accommodate different number of people with different features.

The adherence to the principle of non-interference with nature while you are in such camping trips is an important principle to be followed. Local cultures, usually with strong roots in nature, are to be respected. Understanding the complexity of nature and its diverse role is a critical learning that these experiences seek to offer. The truth that we are part of nature and that nature does not belong to us is important to realize that the relationship between nature and human beings is that of between the mother and her children.

The importance of nature would be fully realized through recreational activities like camping. But if you go camping, responsibility should always be exercised.

Marketing To The Masses

Friday, July 9th, 2010

If you were to invent a self-cleaning fabric, the world may want to beat a path to your door to buy some from you, but first of all they will have to be aware that the fabric exists, that it is available for purchase, and they have to be aware of where your door is. This requires advertising.

There are two classifications of advertising: institutional and product. Institutional advertising markets the name of your company in general and product advertising markets a product or range of products or services. The type of advertising that a business needs, depends on the products or services that it allows.

Moreover, some kinds of advertising lend themselves better to institutional advertising more readily than product advertising. For instance, a shop sign, a sign-written van or a promotional calendar are better cut out for institutional advertising, while a newspaper or magazine advert would be better for promoting the latest special offer.

There are few facts and figures available that bring to light the extraordinary growth of the mass consumption society as well as those dealing with the expansion of the advertising industry. For instance, before the Second World War, US average annual expenditure on advertising per year had been about $2 billion for decades.

In 1950, as the post-war economy began to recover , American businesses spent $5.7 billion to advertise its goods and services. By 1960, that amount had doubled to $12 billion. By 1970, American business was spending $20.

Between 1970 and 1990, as the children Baby Boomers became adults and began earning and spending, advertising expenditure went through the roof, so that by 1986, it had reached $100 billion.

That phenomenal rate of growth could not be maintained, but by 1999, total expenditure on all forms of advertising exceeded $215 billion . The latest available figures are for 2007 and they stand at $280 billion.

In 1999, nearly 60% of all advertising dollars were spent on adverts in newspapers, magazines, on the radio and on television. By 2007, that figure had fallen to about 54% as the Internet started to have an effect on advertising trends. These trends are expected to continue as every firm is expected to have its own web site these days.

The nation’s largest advertisers are the manufacturers of cars, food, soft drinks, tobacco and beer and they filter most of their expenditure through about 13,000 advertising agencies., who normally create the ads and acquire the space or air time from the media too.

These agencies have been transformed over the last decade by mergers. The most lucrative advertising agencies these days are huge international concerns. WPP, the largest advertising agency in the world, billed $37 billion in 2008 and had this to say about itself:

“Our total revenue in 2008 surpassed that of all our competitors, regaining the No.1 worldwide position for the third time”.

Apocalyptic Dates Coming Soon

Wednesday, May 19th, 2010

Predicting the end of the world has almost certainly been going on since man began thinking, whenever that was. It is warned about in Revelations in the Bible, so that must be about 2,000 years ago.

However, it is the predictions of Nostradamus that are the most well-known and most copious. Some biographical accounts of Nostradamus’ life assert that he was afraid of being victimized for heresy by the Inquisition, although neither prophecy nor astrology fell under their jurisdiction. He would have been in danger only if he had practiced magic to back up his predictions.

In fact, his contact with the Church as a prophet and a healer were always very good. His short imprisonment at Marignane in late 1561 came about purely because he had published his 1562 Almanac without the prior permission of a bishop, contravening a recent royal decree.

Here then are a few of the prophesies of the ending of the world and the annihilation of mankind.

December 21st, 22nd or 23rd 2012 are all possible dates for the ending of the world according to the ancient Mayan Calendar.

2012 has been determined by some to be the first potential date for the passing by of Planet X (Wormwood) and the demise of the world, as mentioned in Revelations, although this is fervently debated by Biblical experts and astronomers alike.

2012 is also the year given by Nostradamus as the possible demise. He gave three possible years for the apocalypse: 1994 and 1998 so this is his last opportunity to be correct.

2010 is the year so says the Hermetic Order of Golden Dawn.

In 1143 St Malachy prophesied that there would be only another 112 more Popes. The current Pope Benedict is the 111th. He further predicted that the final Pope would be known as Peter of Rome, so we will have to wait and see for this one.

2017 is the year specified to the Sword of God Brotherhood by the Angel Gabriel.

November 13th 2026 is the date according to a 1960 copy of ‘Science’ magazine. The writer said that this would be the day that the planet’s human population would ‘reach infinity’.

2033 is held by many to be the 2000th anniversary of the crucifixion of Christ and a potential date for his return, which would signal the demise of our Earthly times.

4,500,000,000 AD is the approximate date at which the Sun is due to explode and in so doing, destroy the inner solar system including our World. Nobody knows, but unless we wipe out ourselves first, this latter date is probably the most accurate and scientific date for the destruction of the planet.
