In the old days, and even now, I presume in some places, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or rustlers. These were an early kind of security guard and indeed rich people had and frequently still do have personal body guards.

What if you had a large office with a hundred laptop computers – laptops because employees had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the noses of (or with the help of) private security firms.

So what can you do? Invest in dogs? That works sometimes, but they can be poisoned. Install video cameras and passive infra-red motion sensors linked to a control centre? That works and a lot of businesses and private houses have it, but it is very costly.

As a cheap alternative, the police were handing out free pens in the UK, which wrote in invisible ink. The idea was to put your postcode and house number. This ink became visible under a certain kind of light. That is all very well if you have a suspect or found property.

Bar codes are not practical, the pen is better. It all comes back to insurance or security.

However, there is another way that is becoming reasonably priced. The idea has been around for approximately 85 years, but it was too pricey to use on anything smaller than an airplane or a battle tank.

I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War – a transponder emits precoded information in response to a request from an RF reader.

Details regarding ownership and details of what the item is can be written to an RFID chip also known as a tag and the tag can then be taped inside the item that it is to safeguard.

There are two varieties of tag: the passive and the active. Passive tags will only respond if information is requested by a reader, whereas an active tag is always broadcasting.

Many business people use RFID tagging to keep track of their assets. In the instance of farm animals, most cattle are tagged these days. Most large offices have their IT goods tagged as well and we all know that fashion stores have been tagging clothes for years, although maybe you did not know what that button was that they were taking off at the till.

People are already tagging their dogs, cats and cars and it will not be long before these asset management routines will be employed extensively at home as well. Insurance companies may insist on it.

Well, the fact is that the difference between a hybrid car and a normal car lies under the bonnet. There are different kinds of hybrid vehicles as well, but the most widespread kind has a hybrid electric engine. Therefore, you could say that what makes hybrid cars different from most other, normal cars is their engine.

Or engines really, because hybrid electric cars essentially 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 heavy-duty 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 generated by several components on the car and stored in a large bank or array of powerful batteries. The electricity is created by the turning of the internal combustion engine, just as with a standard car, when it is in use, but also by the wheels or / and the car’s braking system. Different models have different methods of generating this electricity, but they are all very hi-tech and very efficient.

When the car’s internal computers decide that the car no longer needs the strength of the internal combustion engine, it will turn it off and switch to the electric motor instead. The conditions 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 road 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 times when you need more power than the batteries can give you, for instance, 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 need 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 be aware of much other that a surge 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.

Owen Jones, the author of this article writes on many topics, but is at present concerned with hybrid electric engines. If you would like to know more or check out some great offers, please go to our website at New Hybrid Vehicles.

Most people today use steam irons – or even steam generator irons, which are becoming ever more popular. In this case you definitely want to get an ironing board which has a mesh construction. This allows the steam to pass through the fabric of the garment being ironed, through the cover of the ironing board and through the top of the board itself. It helps to prevent the ironing board cover becoming soggy due to condensation after a few garments have been ironed.

The cover of the ironing board should present a smooth surface to facilitate ironing. It should be secure and not prone to slipping. An elasticated cover, possibly with one or two cross-ties at the centre, is generally a good design which won’t move about as you iron. A metalised cover will reflect some of the heat and this will help to smooth the underside of the garment whilst the top surface is being ironed.

The size and shape of the board that you select will depend, to a large extent, on the type of things that you usually iron. Whilst a smaller board may be easier to store and work around, it will normally mean that the garment being ironed needs to be repositioned more frequently. Ironing the shoulders of shirts and blouses will be easier if there is a marked taper on the “pointy” end of the board.

Scissor action legs are pretty much the norm. It should be possible to adjust the height to a level that suits you and doesn’t cause any back strain. If you like to iron from a seated position then legs which have a curve on them – so that you don’t bang your knees on them – are a good idea. The legs should provide good support. A broad T-piece, or legs that splay to a good width and have a connecting bar, are usually good options.

The iron support, usually positioned at the end of the board, should be strong enough to take the weight of your iron. For conventional steam irons a wire frame type of arrangement is usually okay. Steam generator irons tend to weigh a bit more as the base unit usually contains a greater volume of water. A heat resistant plate on a slightly extended board surface may be better in this case. Alternatively, many steam generator irons are supplied with hoses which are long enough to allow the iron’s base unit to be positioned on the floor.

Ironing is a thankless chore at best. Cut it down to size with a Tefal steam generator iron – you’ll be pleasantly surprised at just how much time you can save.

With a market share of 60% of all e-book readers sold in the USA, the Kindle readers dominated the market. Sony trailed in second place with a still respectable 35% share. Needless to say, other electronics manufacturers quickly saw the potential in the nascent e-book reader market and either developed or updated their own readers.

Manufacturers like Bookeen, Plastic Logic, Sony and Barnes and Noble worked hard to get their share of the rapidly developing market, but the dominance of the Kindle seemed pretty well established, if not unassailable. It was only when Apple launched their iPad that the Kindle faced any credible competition – despite the fact that the two devices were very different and, you would think, aimed at different target markets.

Since the launch of the iPad, e-book reader prices have fallen quite some way. The Kindle 2.0 is currently selling for just $ 189, a huge reduction over the $ 359 launch price of February 2009. The large format Kindle DX has been upgraded, being fitted with a new improved screen, and has had a price reduction from $ 489 to just $ 379. Barnes and Noble have also dropped the price of their Nook reader from $ 259 to $ 199.

The launch of the iPad may, or may not, have been instrumental in producing widespread reductions in the ticket price of e-book readers, but it was clearly a major factor in pushing the price of the e-books to read on these devices upwards. Apple had set up its own book store prior to the launch of the iPad and had negotiated a deal with the major publishing firms which allowed them to fix the price of their e-book editions at whatever level they wanted – as long as the e-book was not made available on any other platform for a lower price. This pretty much killed the Amazon policy of setting e-book prices at $ 9.99 or less and was a welcome development for the publishers who were concerned about their profits reducing.

Although Amazon had to modify their approach, it wasn’t all bad news for them – or for Barnes and Noble either. Amazon had always given the impression that they were much more interested in book sales – and e-book sales – than they were in hardware sales. How else to explain the fact that they had bent over backwards to make it possible to read Kindle books on such a wide variety of different devices? It’s possible to read Kindle books on the PC, the Mac, the iPod Touch, the iPhone, the iPad, the Blackberry and any mobile device that runs Android. The latest price movements mean that Amazon, and other companies such as Barnes and Noble – and now Apple – who have a significant stake not just in the sale of hardware but also in the sale of e-books, can adopt a policy of selling the hardware cheap and making their profit in the sale of e-books over the life of the reading device.

It may be that the future pricing of e-book readers and e-books will tend to favor such companies over manufacturers who are involved only in hardware production. Looking at the number of different devices which Kindle books can be read on, you would have to suspect that, whether or not the iPad becomes the reader of choice for many users, Amazon will continue to have a huge say in the future of books and e-books for the foreseeable future.

The Kindle became Amazon’s most gifted item ever over the 2009 festive season – and, on Christmas day of the same year, Kindle book downloads outnumbered orders for physical books for the first time ever. This was probably due to those people who were lucky enough to receive a Kindle as a gift trying it out – and a lot of the downloads would have been free – but it was still a landmark event for both Amazon and the Kindle.

Amazon did seem to be a slightly reluctant manufacturer on occasions however. They seemed to bend over backwards to ensure that Kindle books could be read by people who didn’t have Kindles. At the moment, Amazon has released free Kindle “Apps” for a wide variety of different devices – many of which would be viewed as competitors of the Kindle. These include the PC, the Apple Mac, the Blackberry, the iPod Touch, the iPhone, the iPad and any device running Android. Amazon looked to be their own competition at times.

However, the reasoning behind Amazon’s open policy became clear with the release of the Apple iPad. Among its many features, the iPad can be used to read e-books, and the price of e-book readers went into free fall as Apple enthusiasts rushed to get their hands on Apple’s new device. However, even as e-book reader prices were plummeting, the average price of the e-books for use with them was climbing.

Prior to the release of the iPad, Apple had negotiated a deal with the major publishing houses which allowed them to set the price of the e-book editions of their publications at pretty much whatever level they liked. The only rider was that the same e-book could not be offered at a lower price for any other reader – Amazon’s Kindle for example. Up until that point it had been Amazon’s policy to price e-books at $9.99 or less. Apple’s deal, much to the delight of the publishers, pretty much blew that out of the water. At first glance, Amazon looked to have been hit pretty hard by the release of the iPad.

However, upon closer inspection, it becomes clear that Amazon’s policy of releasing free Kindle Apps for just about every device known to man was a master stroke. Each App is nothing more than an outlet for Kindle books and, given that the price of these is increasing, Amazon can now afford to drop the price3 of their Kindle reader hardware secure in the knowledge that they will make a profit from the sale of e-books over the lifetime of the reader. For that matter, even if the iPad – or any other reader – seriously dented the sale of Kindle readers, Amazon would continue to sell their Kindle books.

However, Apple seemed intent upon spoiling the party when they released their long awaited iPad which, although an entirely different type of device, has the ability to read e-books. Most Apple devices seem to engender a love/hate reaction amongst consumers and there was no shortage of pundits and analysts ready to point out the shortcomings of Apple’s new device. However, the number of people who would buy practically any new gadget which has the apple logo on it is very definitely high enough to make a difference to the sales of Amazon’s Kindle reader.

As well as releasing new hardware, Apple also set up their own e-book store and they negotiated a deal with most of the major publishing houses which permitted them to set the sales price of the e-book editions of their publications at whatever they liked. The one condition to this was that they would not allow any other retailer to promote their e-book edition at a lower price than set for the Apple store. This effectively put paid to Amazon’s plans to offer all e-books at $ 9.99 or less, and e-book prices have been climbing since the deal was struck.

The price of the e-book readers themselves has fallen however. Barnes and Noble cut the price of their Nook reader to $ 199. Amazon’s Kindle 2.0 is now selling for just $ 189 – a huge reduction over the $ 359 launch price of February 2009. The Kindle DX can now be yours for just $ 379, a saving of $ 110 over the previous $ 489 ticket price.

Even the pricey DX model is now over $ 100 cheaper than the cheapest of the Apple iPad range. Neither does the iPad come with connection to the internet for free as is the case for the Kindle range. Of course, the iPad is much more than an e-book reader, so it may be that people are prepared to pay more for a more powerful and versatile device – even if it does have much poorer battery life and a less “reading friendly” screen (which excels for other applications).

It will be interesting to see whether this downward price movement of e-book readers is simply a temporary reaction to the iPad or whether it heralds the dawn of a new pricing policy. It could be that companies like Amazon and Barnes and Noble might take advantage of the trend for higher priced e-books by offering lower priced hardware secure in the knowledge that they will make their profit throughout the life of the device. Or it may simply be a stalling tactic until the next generation color Kindle hits the streets later this year.
