The Indian capital can be now considered, on a global scale, as one the cities where the largest tunneling project has ever been undertaken. According to the Delhi Metro officials this is not an understatement considering the 19 Tunnel Boring Machines (TBM) that are simultaneously working underneath the city. Phase III of the metro expansion is expected to complete by the end of the year.
A collaboration between researchers at the University of West England Bristol (UWE Bristol) and Oxfam, an international organization dedicated to fighting poverty, is proving that urine might be an invaluable source of electricity in refugee camps and other impoverished areas. For decades, utilities in developed countries have derived energy from the methane found wastewater, but in areas where such complex treatment schemes are not possible, simple solutions such as a “pee-power” toilet could offer an inexpensive and desperately needed source of energy.
Massachusetts has experienced a large number of structural failures over the past month due to extreme snowfall. This past Wednesday (March 4th), after an additional 2 inches of snow accumulation, some 20 roof collapses occurred across the state including a large industrial complex in Hyde Park. A 10,000-ft2 section of the roof failed causing a 150-foot long section of CMU wall to crumble into the street alongside the complex. Power and gas lines were also damaged in the failure. Officials stated that this group of collapses brings the total to 21 since February 9.
UK's Royal Mail has just issued a set of first class stamps depicting the 10 most historical bridges across the country. According to Royal Mail, the series "demonstrates leaps in engineering" performed by progressive architects and engineers.
A recent report links high salinity in Seneca Lake, the largest of New York State’s Finger Lakes, to the storage of Liquid Petroleum Gas (LPG) in nearby salt caverns. The lake, which holds 4.2 trillion gallons of water, has for decades seen levels of salt concentrations greater than those regulated by the state for sensitive populations such as infants and those on low-salt diets. The highest concentration, in the village of Waterloo, has concentrations nearly four times the state limit.
NASA's Curiosity Mars team has recently obtained a second soil sample from an outcrop of the Murray formation, the geological unit of Mount Sharp on Mars. Through analysis of the soil samples, scientists hope to understand the formation of the mountain and investigate its mineralogical structure.
