Electric power is essential for all round development, but there are short falls in its supply. Times of India dated Feb 26, 10 discusses about a method using a sand-based bloom box for producing clean and reliable electricity in home or business. This technology made by KR Sridhar, CEO of Bloom Energy, amounts to a glass case, filled with beach sand with the floppy disk-sized ceramic tile buried in it. But the secret lies in coating of the tile with inks, which act as anode and cathode. These are stacked together into a power box. Its size varies from bread loaf to a refrigerator or truck. When natural gas or other fuel is injected into the unit, an electro-chemical process generates power. Some companies like Coca Cola, FedEx and Google are already using bloom boxes. The present estimate of cost of power generation is Rs. 4 per unit (same as at present in India). However this includes state subsidies, which will be required for 10 years, till costs come down. Bloom boxes in use at present for 100 Kw of power for 100 houses costs about Rs.4 Crore. Bread-loaf size units for individual homes may be around Rs. 1.25 lakh but will take 5-10 years. But here multiple fuels can be used, green house gas emissions are reduced and each unit can produce same energy more efficiently, day and night for years.
