Show Harnessing the Rhone, The French rlvor Rhone Is n subterranean subter-ranean stream near Bollegardo, vanishing vanish-ing In a subterranean gulf and there remaining for a considerable distance. The engineers propose to cflange this romantic geology by damming tho rlvor and turning tho water Into two parallel tunnels which will conduct tho rlvor two miles and a half to two power generating stations. Here a fall of 200 feet will yield 150,000 horsepower for 300 days In tho year. Tho cost is ploced nt about $5,000,000, nnd tho use ot tho power Is estimated as equivalent to working nn lnexhnustlblo coal bod supplying 1,600,000 tons a year. |
