This is the first working prototype of the Orrery, or planetary display for the 10,000 Year Clock. This prototype was just recently re-installed at our San Francisco Museum & Store. This part of the clock might help future visitors understand other parts of the clock by accurately showing the positions of the human eye visible planets – Mercury through Saturn. The lower six layers each make a binary mechanical calculation for one of the six planets above. It is designed to make one calculation tick at noon, and again at midnight to update the planet positions. However this display model may be activated at any time, and if you come by feel free to ask for a demonstration.

A new stone base was fabricated for the Orrery recently by the amazing stoneworkers of Seattle Solstice. We wanted a base that showed what this part of the Clock might look like if it were in natural rock. Seattle Solstice sourced a serpentine boulder from a nearby construction site and carefully sliced the top 6 inches off with a wire saw. They then machined pockets for the feet and drive mechanisms so the Orrery would drop right in. You can now see this mashup of stone and metal on display at our Museum & Store.

 

 

The Orrery was conceptualized by Danny Hillis, project management and additional design by Alexander Rose, lead engineer was Paolo Salvagione, and lead machinist and fabricator was Christopher Rand. Other machinists include Erio Brown, Brian Roe, Mark Ribaud, Reason Bradley, General Precision, Oakland Machine Works, Jim Johnson, Brian Ford, Ebin Stromquist, and the base was fabricated by Seattle Solstice

All engineering for the Clock of the Long Now is done in Pro Engnineer courtesy of PTC. All CAM processing is done in GibbsCAM courtesy of Gibbs & Associates. The Long Now Foundation thanks them for their support.

    Wow that’s some impressive prototype!! Great idea

    Amazing site, absolute facinating very impressive prototype’s. Will the plans of the orrery be published

    I would like one of these to put into my wine tasting room I’m planning. It will be in a stone house built before the Revolution, in Highland, NY (once part of New Paltz, the Huguenot’s original patent). The roof and guts of the building unfortunately need to be totally renovated, but those original Dutch walls are still as solid as a rock, no pun intended. I think it would be a perfect symbol of what everything about that property represents to me; an abandoned orchard Ill be working to restore to a working farm, with a conservation easement to preserve it forever, growing wines to last for generations.

    … my point being that you should consider making and selling these to whatever you deem to be worthy institutions, as a way to expand funding for your organization.

    Also, you are based in the Bay Area, CA. If you ever consider making an East Coast branch or whatever, consider the Hudson Valley (Ulster and Dutchess County, as well as a county or two north and south).
