Sun power sends 'high-tech dragonfly' across the US
The plane has an ultra-light, carbon frame and weighs 1585 kilos - about the same as a mid-size car. It has the wingspan of a 747 and a slender fuselage, giving it the look of a giant, high-tech dragonfly.
The plane's power is drawn from the sun by that form the top of its wings. It is collected in a series of batteries arrayed behind the craft's four electric engines.It routinely reaches altitudes of up to , well below the thin air traversed by big commercial aircraft zipping around at close to . On-board instruments alert the pilot if the plane banks even a degree too far.For all of its innovations, at this piloted across the Atlantic Ocean in 1927.The plane's engines put out about 10 horsepower - roughly the same amount as the Wright brothers' first planes. Solar Impulse cannot take off or land in windy conditions, nor can it fly through clouds. The lone pilot wears a parachute and is confined to an area the size of a ''bad economy seat,'' noted the project's chief executive and co-founder Andre an engineer and former fighter pilot.The tiny cockpit is unheated the pilot must endure extreme heat and cold and wear an oxygen mask.

There were exceptions, in the chemistry and biology labs, in carpentry class.and in the gym. But by and large I grew up in a listen-and-learn culture. When I emigrated to the it was the first time I’d ever left India; in fact it was the first time I’d ever lived in a I had no choice but to listen, to understand what people were saying (their accents were strange to me), to understand what they meant (the words, idioms and usages I’d never come across). It pays to be quiet hment of children, mothers can tell if the crying comes from one of theirs or not. Amazing. Yet natural and innate. And to be expected. Similarly, a week-old baby can tell if the voice she hears is her mother’s, and is calmed. Soon after, she can distinguish her questioning. And then I started working, and came across new authority models. After a while it all became the same thing. It wasn’t about obedience or following orders or authority figures or anything didn’t speak French or German. But I listened French and German. I knew enough to be able to translate some of what was being said. Which led to some very interesting inadvertent participations in conversations in lifts and in meetings, as others assumed I couldn’t understand a word. Live and learn.I listen to test and reflect of what I’ve learnt about cooking has come about by my listening to my wife; some of it has come from listening to cooks, often face to face in their restaurants and kitchens, sometimes on TV, occasionally in a cookery class. And it was in a cookery class that I learnt to listen to food, to use the sound of the food to tell whether something is ready or not. This seems particularly true for sauces and stews, but I’ve even heard it applied in other circumstances.in such circumstances.So I walked lifts and in meetings,everywhere. It was a time when time
