That's unfortunate, according to scientists at the Dr Panjabrao Deshmukh Agricultural University in India, because using the sun's power to
heat water is a far more efficient process and offers a much quicker return on investment: According to their analysis, published in the International Journal
of Global Energy, as the payback time for a
solar water heating system is about two years (with a lifespan
of 20), this is a far more cost - effective use
of solar energy in the developing world than using it to generate electricity.
Integrated with the roof is a
solar hot
water system, which aims to provide 80 %

heated water.
Sources
of heat include: industrial and process sources such as power stations, industrial processes (such as chemical industries, clinical waste incinerators and food producers), building cooling
systems and refrigeration (such as offices, supermarkets and data centres), sewerage
systems and
water treatment works, London Underground tunnels and electricity substations; and environmental sources — air, ground,
water (that retain
solar heat).
Amazingly, seventy per cent
of the hot
water is derived from
solar panels on roof with the remainder being provided by the air source
heat pump in the ventilation
system.
It will, however, utilize many
of the same elements: waste and
water will be recycled and reused, housing will be built and orientated to take advantage
of prevailing winds and maximize energy efficiency, efficient district - wide
systems will handle
heating and cooling, and electricity will come from planned wind and
solar thermal plants, or be generated on site.
The highlight is most probably Fred's impressive, self - built woodstove, which is part
