Wind-powered car breaks record

A British engineer from Hampshire has broken the world land speed record for a wind-powered vehicle.
Richard Jenkins reached 126.1mph (202.9km/h) in his Greenbird car on the dry plains of Ivanpah Lake in Nevada.
Mr Jenkins told the BBC that it had taken him 10 years of "hard work" to break the record and that, on the day, "things couldn't have been better".
American Bob Schumacher set the previous record of 116 mph in 1999, driving his Iron Duck vehicle.
"It's great, it's one of those things that you spend so long trying to do and when it actually happens, it's almost too easy," Mr Jenkins told the BBC.
The Greenbird is a carbon fibre composite vehicle that uses wind (and nothing else) for power. The only metalwork used is for the wing bearings and the wheel unit.
Sail away
The designers describe it as a "very high performance sailboat" but one that uses a solid wing, rather than a sail, to generate movement.
Mr Jenkins, from Lymington, spent 10 years designing the vehicle, with Greenbird the fifth vehicle he has built to try to break the record.Due to the shape of the craft, especially at such high speeds, the wings also provide lift; a useful trait for an aircraft, but very hazardous for a car. To compensate for this, the designers have added small wings to "stick" the car to the ground, in the same way Formula 1 cars do.
"Greenbird weighs 600kg when it's standing still," said Mr Jenkins. "But at speed, the effect of the wings make her weigh just over a tonne."

World cities begin big switch-off

Millions of people worldwide are being urged to switch off lights for an hour, in what is described as the biggest climate change protest ever attempted.
The initiative, Earth Hour, was begun in Sydney two years ago by green campaigners keen to cut energy use.
Correspondents say the aim is to create a huge wave of public pressure to influence a meeting in Copenhagen later this year to seek a new climate treaty.
Critics describe the event as a symbolic and meaningless gesture.
The switch-off is expected to take place in more than 3,400 towns and cities across 88 countries, at 2030 in each local time zone.
Earth Hour was launched in 2007 as a solo event in Sydney, Australia, with more than two million people involved. Last year's event claimed the participation of 370 cities.
Organisers say they want to demonstrate what people can do to reduce their carbon footprint and save energy, thus drawing attention to the problem of climate change.

Energy suppliers 'overcharging eight million customers'

Energy suppliers are still taking unnecessarily high direct debit payments from millions of customers each month.

A survey by Which? the consumer group, found that 65 per cent of respondents are in credit with their energy supplier but are still being overcharged. A quarter were owed at least £100 – despite the research taking place in winter, when energy use is normally higher.

Around 12 million households pay for their energy with direct debit, according to Ofgem, suggesting as many as 7.8 million people could be paying too much. Which? says that suppliers are using their customers’ money as “interest-free loans.”

Martyn Hocking of Which? Money said: “It seems incredible that energy companies can take hundreds of pounds more than they need to from their customers, and profit from the interest that this money will earn at our expense.
Which?’s survey also found that energy suppliers are one of the worst industries at delivering customer satisfaction. Npower was deemed the worst energy provider, with a satisfaction score of only 30 per cent. Utility Warehouse achieved the highest customer satisfaction score of 83 per cent.

The World's Cheapest Car

India's Tata Motors has launched Nano, the world's cheapest car. Hormazd Sorabjee, one of the first journalists to test drive the car, says it feels more expensive than it is.

I have to admit I had a nagging fear that the Tata Nano wouldn't live up to the media frenzy that's been surrounding it.

It's been the most awaited car in the world and the delay in putting it on the road - due to the relocation of its production facilities - only increased the sense of anticipation. There's been an apprehension that Tata's self-imposed price target of 100,000 rupees ($1,979, £1,366) would make the Nano an apology of a car and sceptics expected a glorified golf cart.

However, after driving the Nano in the western Indian city of Pune - home to Tata Motors - on the highway and rural back roads, it's turned out to be quite the opposite.

The Nano feels significantly more expensive than it is and a car you certainly won't be ashamed to sit in. It thrilled me with its "proper car" feel and I also learnt to forgive it for its shortcomings. I can live with the ridiculously small 15-litre fuel tank because the car's phenomenal efficiency (18-20 kilometres to a litre) would give it decent range.
