Having done a quick scout around on the web, I see that the quoted torque for both an E400MMC and a Mercedes Citaro is less than a third of what is available here. This should make for good pull-aways at stops.<br /><br />I realised this when I read a review of the electric version of my car which, though heavier than the petrol model, apparently shoots away from traffic lights! Both electric and steam vehicles offer maximum torque when starting from rest, however internal combustion engines offer zero power when starting from rest; the power has to be transmitted through a clutch as the engine speed and power increase.Andrew Kleissnernoreply@blogger.comtag:blogger.com,1999:blog-7432323264902617108.post-26591991997054222552017-08-19T08:04:58.663+01:002017-08-19T08:04:58.663+01:00One problem with mains electricity, alternating cu...One problem with mains electricity, alternating current (a.c.) is that you cannot store it in that state.<br /><br />To do so you have to convert it to direct current (d.c.)<br /><br />The national grid is a.c. And it is more efficient at higher voltages. For domestic use in the U.K and Europe (generally) we reduce it to a nominal 240 volts (it has varied over the years between 200 volts and 250 volts) but for outdoor use including building sites it is reduced further to 110 volts for safety reasons.<br /><br />Electric trains use higher a.c. Voltages with the overhead pantograph, whereas in the south east of England we use 600 volts d.c. With the third rail.<br /><br />Batteries and accumulators as used in torches and electric vehicles are d.c.<br /><br />For further information google d.c. or a.c. - look up websites such as wiki and science based websites that will also be found.<br /><br />No doubt our blogger will have an electric journey today.Anonymousnoreply@blogger.com
