What are the options and explain what is the best technology available for powering cars of the future, and why is that

Is creating energy and electricity through nuclear power plants, a sustainable energy source, in order to augment reliance on fossil fuels an ethical idea when compared to other technologies, such as solar, wind, and natural gas? If so, on what basis? If not, why, and is there anything that could bolster its ethical production?

Compare Celebrity to other cruise lines in terms of sustainability.

1.Why have eight cylinders in an engine? why not have one big cylinder of the same displacement of the eight cylinders instead? 27. What causes white smoke in two stroke locomotive engines? 28. Why efficiency of gas turbines is lower compared to internal combustion engines?

d) Use the Taylor Tool Life equation to estimate the tool life (in minutes) for this operation. Use the table below to pick appropriate values of C and n (the flashlight material is titanium and the tools are high-speed steel). How many such holes would you be able to drill before the tool needs to be replaced? Nonsteel Cutting Steel Cutting Tool Material m/min (f/min) m/min f/min Plain carbon tool steel 0.1 70 (200) (350) (2700) 20 60 High-speed steel 0.125 120 70 200 Cemented carbide 0.25 900 S00 1500 Cermet 0.25 600 2000 Coated carbide 0.25 700 2200 Ceramic 0.6 3000 10,000 Compiled from (4). [9), and other sources. The parameter values are approximated for turning at feed = 0.25 mm/rev (0.010 in/rev) and depth - 2.5 mm (0.100 in). Nonsteel cutting refers to easy-to-machine metals such as aluminum, brass, and cast iron. Steel cutting refers to the machining of mild (unhardened) steel. It should be noted that significant variations in these values can be expected in practice. Table 1.…
