The National Robotarium is supporting the development of new artificial intelligence and control systems that could allow underwater robots to operate autonomously and with high precision in turbulent seas, potentially revolutionizing maintenance and repair tasks for offshore wind turbines. ...
As outlined earlier, current models suggest that approximately 10,000 Bq/m3of radon in water (which is equivalent to 10 Bq/L in water) is needed to increase radon levels in air by 1 Bq/m3; this implies that to observe a + 17 Bq/m3average excess of radon in indoor air attributabl...
Based on case studies in rural Africa [22], drilling each borehole with a small diesel engine and 6 to 8 laborers results in depths of 15 to 20 m per day for a maximum of five days and 15 to 20 L of diesel fuel per day [21]. Water is drawn out of each borehole using either...
The application of water-fuel emulsion (WFE) in internal combustion engines enables to reduce the consumption of sulfurous fuel oils, thereby protecting the environment from emissions of sulfur and nitrogen oxides, as well revealing a great potential for the heat utilization of exhaust gases. The ef...
fuel cost against gas turbine electricity is 8.37 to 2.34, in gas turbine's favor. The issue with large dams' power is the maintenance of the fucking dam from cracking, silting, and the hydraulic turbines' massive blade damage and repair costs coming out of high speed silt and rocks ...
