"This is the experimental model of the apparatus with which I hope some day to so harness the rays of the sun that heavenly body will operate every machine in our factories, propel every train and carriage in our streets, and do all the cooking in our homes, as well as furnish all the light that man may need by night as well as by day. It will, in short, replace all wood and coal as a producer of motive power and heat and electric lighting."
"In this way electricity will be so cheapened," says Mr. Tesla," that it will be possible for the poorest factory-owner to use it as a power at a smaller cost than steam. Electricity will in this way supplant steam as a motive power on all railways and -- in the shape of storage batteries -- on all water vessels. And the humblest citizen will profit by the new system of producing electricity; for he can have it in his home to do all his cooking and lighting and heating. and it will be even cheaper for him than coal, wood, or petroleum."

This would really be in big demand. Why didn't he sell any? Nevermind. Google shows several websites that for $25 you can get Tesla's plans, along with 99 other "free-energy" projects. Why don't you send in your $25 and build a few. Then get back with us.
