Husk Power Systems serves 150,000 people through its 60 systems in villages of Bihar, West Bengal and Tamil Nadu. They generate 35 to 100 kilowatts of power using "mini power-plants" that provide 8-hour of lighting mainly in the evening.

Refrigerator without power

Can you imagine a fridge made of bricks, cement and coarse sand? The Central Arid Zone Research Institute, Jodhpur, has done it. The mechanism is based on evaporation where the temperature inside is 12-15 degrees lower than room temperature, while humidity is higher by 85pct. This was aimed to meet the problem of preserving fruits and vegetables in the scorching heat of Rajasthan. The 'fridge' can preserve 30kg-50 kg of vegetables for 4-5 days in summer and 6-7 days in winter.
