Just as small, fast-moving mammals replaced lumbering
dinosaurs, pocketable gadgets are evolving to fill niches that
larger, deskbound computers can't reach. But as they shrink,
these gadgets are faced with problems mammals face, too,
such as efficiently dissipating heat.
The recent example of Apple's first-generation iPod nanos
causing fires in Japan raises the question of whether
increasingly innovative product designs are impinging on
safety. The nano incident illustrates how risk can increase as
devices decrease in size, says Roger Kay, an analyst at
EndpointTechnologies.
"As [gadgets] get smaller, the tradeoffs become more difficult,
the balance becomes more critical and there's less room for
error," Kay said. "I'm not surprised it's happening to the nano
because that's the small one. You're asking it to do a lot in a
very, very small package and that's pushing the envelope.”
There's no question that industrial designers' jobs have
become much more difficult as the industry demands ever
more powerful and smaller gadgets. With paper-thin
subnotebooks, ultrasmall MP3 players, and pinkie finger-
sized Bluetooth headsets becoming increasingly popular, it's
questionable where exactly designers draw the line between
innovation and safety.

There are lots of things you can do to save energy at home, from simple things like washing at 30 °C, saving water and
recycling, to insulating your loft and cavity walls. By saving energy you’ll be reducing your home’s carbon dioxide (
) emissions and helping to fight climate change.
Why should you save energy?
Over 40 per cent of the UK’s man-made
emissions actually come from energy we use every day – at home and when we travel. To generate that energy, we burn fossil fuels (coal, oil and gas) that produce ‘greenhouse’ gases – in particular
– which are changing our climate and damaging the environment.
The greenhouse effect
and various other gases wrap the Earth in an invisible ‘blanket’, helping to prevent heat from escaping. Without this greenhouse effect, the average temperature on Earth would be around -18 ºC, compared with the current average of around +15
ºC. This blanket of gases has remained at a constant concentration for many thousands of years. Since the Industrial Revolution
began around 200 years ago, people have been burning more fossil fuels. This has increased the heating effect of the ‘blanket’,
trapping more of the sun’s energy inside our atmosphere. In turn the Earth’s temperature has increased more rapidly in a shorter
period of time than it has for thousands of years.
The impact of climate change
People sometimes think that climate change will be a positive thing for the UK, giving us warmer summers and fewer cold
winters. But hotter summers and less rain in the south and east will mean water shortages, forest fires and damage to crops and
wildlife. In the north and west there could be much heavier rain and more flooding. As the polar ice caps continue to melt, rising sea
levels will threaten many coastal communities. Overall, the cost to society, the environment, our health and the economy is likely to
far outweigh any benefits.
Make a difference
The average UK household creates around six tonnes of
every year – that’s 6,000 kg – to heat and power their home. Making your home more energy efficient could save you up to £340 a year and reduce your home’s
emissions by up to 1,500–2,000 kg. You could save even more by switching to renewable energy sources, by walking, cycling or using public transport
whenever possible, and by driving more efficiently.

1. because we spend less money.
2. because a great part of the
produced by humans is a result of energy used at home and when travelling. 3. because the world does not have enough fossil fuels.
4. because fossil fuels are too expensive.
5. to fight climate change.
Based on the statements above, choose ONE alternative:
