What a pity that about
80% of all the energy that is collected by Wind Turbines in the UK, is then
wasted by being blown out of the exhausts of the 22 million Vacuum Cleaners
that are used in England and Wales
A few simple calculations
will show that in England and Wales alone 22 million vacuum cleaners are
blowing out energy of a vast proportion, and wasting energy at the rate of
about 750 watts, of kinetic energy each, every week.
are a total of 22,539,000 households in England and Wales alone, if each
home uses a vacuum cleaner for just eight and a half minutes a day, (a total
of one hour per week,) they waste approximately 750 watts or 0.75 KWh of
electricity, per week. This does not include shops, hotels, and offices etc.
million Vacuum Cleaners each one losing 0.75KWh = 16,500,000 KWh per week
that is 16,500. megawatts of power being thrown away or lost each week.
megawatts a year of wasted energy.
A medium sized wind turbine
with a total of 400 Kwh capacity is only working for about 20 to 30 percent
of the time and so is only averaging 25% of 400 kwh that is just 100 kwh,
I00kw per hour times 24
hours in a day = 2400000 watts, times 365.25 days in the year = 876,600,000
or 876.6 megawatts of power generated per year per windmill.
858,000 divide by 876.6
equals 978 almost 1,000 medium sized wind turbines is wasted.
This means that it takes
almost 1,000. medium sized 400 KWh wind generators to provide the energy
that is being wasted in the air that is blown from 22 million vacuum
That is more than 80% of
the entire output of all the wind farms in the UK.
This does not have to
happen, a system has been researched and has proved to be a viable and
economical way of returning this wasted air power, back into the cleaner
head and using it to do useful work.
Prototype Air Recycling
Cleaners that use only 250 watt hour of electricity have been tested on
behalf of the Market Transformation Program and prove that they will clean a
carpet as well or better than a conventional 1,500 watt vacuum Cleaner.
But an even more
important issue is at stake.
