    Bill Nye's '77 Solar Noon Indicator over Rhodes Hall

Bill Nye "the Science Guy", Mechanical Engineering class of 1977, dedicated a unique clock that he donated to Cornell for the facade of Rhodes Hall at a ceremony on August 27, 2011. Beside simply telling the time of day, this clock illustrates the difference between legal and solar time by letting light illuminate a disk at the precise time when the sun culminates overhead. In memory of his parents, Bill Nye personally designed the clock and its light guide. See Bill Nye's lecture here.

In 2009-2011, Michel Louge led the group of students (Avraham Aisenberg, Erin Boschert, JB Rajsky, Steven Shine and Ian Werris) who designed the microcontroller that lets light through the Electric Time monumental clock. The microcontroller calibrates time with a GPS and opens a Solatube dimmer letting sky light shine at Solar Noon, per calculations in this worksheet.

Tamara Linsdtrom of YNN Ithaca/Cortland produced this piece on Bill Nye's creative project (August 24, 2011). Alyson Martin filed this report for the Ithaca Journal of August 24. Daniel Aloi wrote this article for the Cornell Chronicle. Channel 9 News in Syracuse posted this piece on its website. Byron Kittle, of the Cornell Daily Sun wrote this article on Bill's dedication. Joe Wilenski of the Cornell Chronicle reported dedication day in this pictorial article and posted a video of Bill Nye's visit.

Bill Nye'77 explains his parents' history

From left to right and top to bottom: Bill Nye '77 "the Science Guy" personally directs tests of the Solatube system above the roof of Rhodes Hall on March 27, 2008. The Solar Noon controller team works with Bill on October 19, 2009, and later enjoys Chef Harold Evans' table at North Star.  Electric Time and Cornell Facilities raise the clock on August 3, 2011. The Solar Noon indicator is fully-operational on August 18, 2011.  Note the contrast between the indicator with closed dimmer valve (left) and open valve (right). JB Rajsky poses on the roof and near the clock. Michel Louge shows the Solatube Fresnel lens that collects ambient light for the clock face. He poses in front of the clock on August 19, 2011 at Solar Noon. Bottom: Bill Nye'77 shares details of his parents' WWII history in front of the display case in the Rhodes Hall lobby.

    Solar energy

This workbook uses solar ephemeris to calculate the fraction of radiation collected by PV solar panels at a fixed orientation in 2014. For subsequent years, follow instructions therein after downloading the new ephemeris from, or look for updates on this page.
