Emery Blagdon spent his life building a "healing machine". His immediate family has died of cancer and he knew by direct experience, how illness and suffering build human helplessness. So, he was a firm believer that energy made people feel better and that was what he wanted to do with his work.
"The Healing Machine" was designed to channel the earth's energies to alleviate pain and illness; it was that belief that prompted him to eagerly explore the curative potential of electricity.
