Today, a fight is looming over the ghostly remains of that site, called Wardenclyffe — what Tesla authorities call the only surviving workplace of the eccentric genius who dreamed countless big dreams while pioneering wireless communication and alternating current. The disagreement began recently after the property went up for sale in Shoreham, N.Y.

A science group on Long Island wants to turn the 16-acre site into a Tesla museum and education center, and hopes to get the land donated to that end. But the owner, the Agfa Corporation, says it must sell the property to raise money in hard economic times. The company’s real estate broker says the land, listed at $1.6 million, can “be delivered fully cleared and level,” a statement that has thrown the preservationists into action.

The ruins of Wardenclyffe include the tower’s foundation and the large brick laboratory, designed by Tesla’s friend Stanford White, the celebrated architect.
