Where's my solar power missing?

In the first 2 designs the temperatures in the fluid or atWhere's my solar power missing? the collector tower, in contrast to temperatures in solar water heaters, are adequate to produce steam; the third design does not use steam at all, but is powered by a Stirling engine, a closed cycle heat engine capable of very high efficiencies.

The largest solar power system in the world (350 MW) is located in California's Mojave Desert and uses parabolic troughs to convert sunlight to electricity with an efficiency of about 20%. Using the second design, Spain is building a 15 MW solar power tower in Andalusia, and an even larger such system is planned in South Africa. And using the third design, which will have total conversion efficiency as high as 30%, Sandia National Laboratories & Stirling Energy Systems are building a prototype of a system which will generate electricity at the same cost as the conventional technologies.

Never before has there been so much international focus on environment

The great apes of the world could become extinct in the wilds within a single chimpanzee’s lifetime, which is about fifty years. The world’s oceans are being depleted. Industrial fishing has wiped out perhaps as much as 90% of large predatory fish species such as the biggest types of tuna. Right now the fate of the whales, big cats, elephants and many other species are increasingly becoming bargaining chips on the gaming board of global economics and international pawn-playing politics. And because of social factors such as stress, feelings of worthlessness and loneliness of spirit, we are now, quite literally, killing ourselves. Suicides amongst our teenagers, the loudest cry for help of them all, have reached almost epidemic proportions in today’s world.

Low lying Bangladesh may drown

Brahmputra and Ganges, which join together in Bangladesh before falling into the Bay of Bengal, are filled by the melting snow of Himalayas. Deforestation in Bangladesh is one of the reasons that has led to a rise in the level of river beds, which has made floods not only recurrent, but disastrous. Since 1971, the frequency of the floods has augmented – 1974, 1984, 1987, 1988, 1998 & 2004. But the fear now is not floods. It is the likeliness of the complete submergence of the country. This is because as much as 15-20% of Bangladesh is already within 1 metre of sea level.

Rest in peace...

For manyHCL computer fanatics, the hottest buzz this March wasn’t the marvellous results posted by IT companies but was the launch of eco-friendly laptops by HCL. By introducing a complete range of eco-efficient consumer & business notebooks in compliance with the EU directive on Restriction of Hazardous Substances (RoHS), showing some intent on making its presence felt in the green arena. When asked about the business imperative, Rajendra Kumar, Executive VP, HCL Infosystems, states, “It won’t be fair to label eco-friendly laptops with tags like ‘making business sense’ or ‘a regulatory burden.’”
