As some of you know I've been making a mini-documentary about the historic Elco boats inspired by Edison's early batteries.   I documented a very special one that was one of the earliest after attending Kevin and Becca's wedding.    The old Elco is located on Green Lake WS about 100 mi. north of the Beloit Show.

Well, after talking to the gent who purchased and rebuilt the old Elco Company, I learned that he had recently built an electric launch for the newly restored Forest Park Grand Basin where the 1904 World's Fair was and that Elco had made the first electric launches for the public in the earlier Chicago Exposition.

So, yesterday I drove over to The Grand Basin in Forest Park and recorded the beautiful electric runabout "The Enterprise" I did not see it in action but it appears to be a retro-classic with minimal propulsion (one small motor and 6 batteries).

Here's some guys with a pretty impressive boat, if it's real it definitely is a breakthrough in engineering. The usual outboard to electric conversions are with small motors and go about 10mph.  So, I don't know what these guys are doing exactly, but they seem to be having a good time doing it.

If anyone's interested, here's the blog from my website where I talk about the limitations of electric vessels and the benefits.   Traditionally there's been established physics equations of power output, battery weight to sustained output and weight of the necessary vessel for the batteries and motor that created a theoretical speed limitation.   More power, more batteries, more weight, less speed vs. the reverse power to weight ratios.  Einstein couldn't have got past the physics.   What these guys are doing is probably using new motor design, the newest battery designs and computerized power usage controlls.   And, how much of that hull is filled with really expensive batteries anyway?
I plan to look into their alternative boat building materials as well.   The motors were designed in the U.S. The boats are for the European market but they are built in Canada.
