Show POWER FROM' LAKE GENEVA Two suggestions have been mado for exploiting the Lake of Geneva for tho benefit of Paris, one being to convey con-vey Its water through an aqueduct to Paris and the other to utilize tho water wat-er power of the fpper Rhone at Its outflow from the' lake. According to the latter it is proposed pro-posed to build a huge embankment at Genissait, which is to convert tho wholo valley of tho upper Rhono as far as Geneva Into an artificial lake 23 kilometers long, with a capacity of 50,000,000 cubic meters The head of 67-69 meters thus availablo would supply up to 246,500 kilowatts, while the number of kilowatt hours available avail-able during a year would bo equivalent equiva-lent to tho energy supplied by the combustion of 1,500,000 tons of coal Tho power-house at the foot of the embankment Is to contain 24 units of 10,000 kilowatts, or 16 of 15,000 kilowatts, and three-phaso transmission transmis-sion at 120,000 volts (possibly 150,-000 150,-000 volts) is to bo adopted, tho current cur-rent being generated at 12,000 volts and transformed up In a transformer house about SO feet long Tho Francis turbines are to work at a spoed of 250 revolutions per minute, and tho continuous current excited machines (750 kilowatts, 160 volts) are to be operated by vertical turbines. Each turbo-genorator .set Is to be quite self- contained. The four high-tension transmission lines from Gonlsslat to Paris are to convey no less than 80,000 to 100.000 kilowatts. T(hoy are to be divided into two groups, following different paths, each lino to bo subdivided by section switches Into sections of 100 kilometers oach, transverse lines permitting any injured in-jured section to 'be cut out without Interfering In-terfering with the operation of tho plant. They are to consist of aluminum alum-inum linos arranged ton feet apart and carried by steel towers sixty five feet in height. A thick galvanised galvan-ised steel protective wiro is to run on top of the lines. London Times. |
