Editor's Notes

[letterhead Columbia Coll School of Mines] What's cost of dynamo to deposit one ton of copper in 24 hrs? TAE marg: "If you mean depositing from one plate of copper on another plate or metallic object then the size of the dynamo would depend upon the surface exposed. With any given current the amount of copper deposited will be at the square of the surface. Our 60 light machine can be altered to give 8 volts and 750 amperes price $1,300. From this data you can calculate what you can do."
