Daylighting LEGOs and a virtual sky cupola

Virtual Skylighting is about to take a new twist: stackable daylighting LED rods that connect together like LEGOs. This will allow these thin rods of tunable white to be arranged as an assembly of up to six per power supply/battery pack.

Imagine a circular arrangement of these around an interior cupola: at dawn the easternmost rod begins to illuminate the room below with the reddish tint of the rising sun. As the morning progresses, the eastern group gradually expands spatially as neighboring rods are activated and the light increases with a cooler hue, just as the sun is doing outside. At midday all of the rods in the circle are lit to maximum intensity. The afternoon sees a shift to the western rods and a lowering of brightness and color temperature, culminating with a single warm white rod at the westernmost extent gradually extinguished as the sun sets.

For a portable or UPS assembly, Li-ion battery pack will take on this new stackable form. We plan to use the same connector as is used on the innovative Lenovo Yoga notebook computer:


Each linear element LED rod and Li-ion rod will have an Espressive ESP32 Wifi/BT module with dual core Transilica processor so will connect to your smartphone for customization and also will communicate with each other. These will be web servers for your use as well as web clients that will access worldwide web cams to collect sunlight brightness and hue, a true revolution in Natural lighting available this August.

  1. The product and application sounds fantastic! Looking forward to learning more.

  2. My buddy Keith Parker touts new versions of Power Over Ethernet that may carry up to 2 amps at 48 volts. He focuses on leapfrog technology for the developing world; rather than wiring dumb always-on three prong sockets with AC, feed superefficient devices with smart power from power supplying hubs, tailored by identification, negotiation, and characterization over the ethernet connection.

    The US is 5% of the world’s population, and a small percentage of the world’s incremental economic growth. The big growth markets are nations skyrocketing out of poverty. Cell phone sales in impoverished rural India were growing at 2% per month recently, though that market is approaching saturation now. 2% of a billion people is outstanding sales growth.

    US investors will support development of products targeted for US impulse buyers, because that is what they understand. But the revenue that actually builds your business will come from emerging nations, along with the “karma” that energizes your hard work.

    So – develop the consumptionist geegaws, but include options that support developing world leapfrogs. You may fail to outcompete the thousands of other consumptionist products competing for the same dwindling US consumer dollar, but getting as big as Carlos Slim (who got rich peddling cell phone service to Amazonian jungle dwellers) might be a tolerable alternative.

    • That Carlos Slim remark made my day! The great part about LEDs is that they are saving huge amounts of energy and are becoming affordable as well. A great example of how this is empowering undeveloped regions is the gravity powered luminaire ( that can run for hours on a bag of dirt and at the same time eliminate fossil fuels such as kerosene once the only source of light after dark.
      Your ServerSky is the ultimate, I was looking at the Google server complex in The Dalles recently, they are not using the location for green purposes though, just milking our relatively cheap electricity and consuming more than Las Vegas at night!
      If all that could be moved into space we would could have limitless solar power and zero emissions and more importantly zero additional heat pumped into the environment.
