About this community
We progressively surrender most of our point-source bulbs. Those that remain are for decor, not for illumination. Big LED plate lights occupy recessed-light locations. In time lights get smaller, distributed and remote-controlled with DC wiring. Light elements are with standard-everywhere low-voltage connectors like audio jacks. New luminaires are forward-compatible with OLED elements.
And - - seeing that PV arrays fail to serve in a disaster if grid-tied, let most lighting and crucial electronics be off-grid. Silly us, to want to generate income with a PV array, in the grid. In this, lights wired as low-voltage DC, auto and marine as the active example, will prevail over now-competitive chip-on-board AC LEDs. Why might we need AC LEDs? Strip boards down to only diodes and wires: that's what lasts forever. All fragile electronics clustered, serviceable, elsewhere.
I find no help yet in the participation at this community.
Searching the internet for vision and progress, try this as a Google search:
"distributed power generation for lighting and crucial electronics ."
Find commercial buildings progress in this Carnegie Mellon report , in LEDs Magazine. From this, discover the Emerge Alliance , "an open industry association leading the rapid adoption of safe DC power distribution in commercial buildings through the development of EMerge Alliance standards."
At the Emerge Alliance home page, find this link to Mother Nature Network:
The home of tomorrow will run on direct current
See that advanced thought is coming from Lloyd Alter, blogging from Toronto:

The vision of collection on each home may sound extreme, and in fact is not absolute. Many means of local cooperation can evolve. Here is one vision of rather large collectives for distributed generation, in India:

In the USA, a campaign open to every individual home might be necessary. Any urban divorce from the grid would be disruptive. A little alienation, voluntarily in every home, can not be stopped. Each participant finds the best-yet way to cooperate in guarding life on Earth against consumptive waste.With that beginning, find other means of expression. A typical path will be separation from the grid in the overhead lights chosen (eventually all). Where ceiling junction boxes are stupidly packed with power distribution to outlets, much rewiring will be afforded by the sure savings. Homes will become safer. With all other prep as in closure of attic floor pits, now add overhead insulation. And, never, never add insulation that gets in the way of needed repairs and largest savings opportunities. Repairs shall include fixing ventilation problems at bad noise-maker fans, badly ducted, and promotion of good attic ventilation by correcting deficient soffit vents.
I am committed that I will do a trial installation in my own home. I invite development of other projects through inspiration at community Build It Solar:
- Let's see who gets a project done first. My first room will employ Nicor DLS lights minus the AC to DC converter assembly in each luminaire. The AC is separable with twist connectors. I want to build little lights with minimal additions to inexpensive light engine boards, where the biggest challenge is in cobbling up connector jacks, using audio components to start. In time, push-pluck connectors will be universal and will cost almost nothing, enabling very wonderful light as art, always low voltage and outside costly regulation.
