Richmond's Solar Sidewalk!

I know I blogged about InLight, Richmond's first "Art, Turned On" addition to First Friday and celebrating 1708 Art Gallery's 30th anniversary last week.

But for you geeks like myself out there, thought I'd expound more on the technical green building/solar information as well as the volunteers whom made the Solar Sidewalk possible.

('Cause. I'mma geek. Better than playin' with Legos!)

Scott Kyle, the green building architect who created this piece, explains:


"A quick description of the system:
Two Kyocera 65 Watt PV Modules, 24V Solar Lighting Control, & two 12V Concorde SunXtender Deep Cell Batteries.

This is what is showing up in my truck and on the roof with the guys from Cityspace Construction (Richmondcityspace.com), who volunteered time and materials to the cause.

















Thanks also to Kenny, whose rooftop apartment we have to go through every time we have to access the roof.

Next, there is 24V DC wired from the roof to inside the window seat at the storefront of 1708 where there are two 25W LED Fiber Optic Illuminators (http://lightbeaminc.com/illuminators_25_watt.html).

These are state of the art illuminators with very high light output and very low current draw, ideal for photovoltaics. If we would have used halogen, which is standard for fiber optic illuminators we would have had to have added four more PV modules (yes there is a lesson here for homeowners and their appliances and lighting).

The fiber optic (plastic filaments) bundles are divided into four smaller bundles from each of the two illuminators where they are brought to each of the eight concrete panels in metal conduit that are then covered in sidewalk cement.

That's Stan Webb of Concrete Ideas handling the fiber optic cables. Stan's company manufactured the fiber optic concrete panels in their shop in Richmond. The PV modules are illuminated at dusk and stay on for a set period of time (currently 8 hrs - long enough for staggering club dwellers to see their way home by). The PV controller takes care of the battery charging and control of the on-off cycle. "

Thank you, Scott, for sharing your wonderful project with us!!!!
Er, see ya at Green Drinks Thursday! : )





There is no photograph that can accurately freeze-frame/capture it, except to see/experience it.


Below is my video where I tease Scott (his wife has a degree in sculpture)...
but it kind of gives you the "experience" of seeing this nice addition to Richmond at night...

A great addition to the Richmond arts scene- it is a good time to be in Richmond!

These sidewalk design elements are beautiful. I love on how they flare at night.
