Storing energy  from renewable sources is needed for use when the sun isn't shining, or wind blowing, or just to be able to buffer peak demand.  

This has been an expensive part of projects where renewables aren't wired in to the grid.

Phil commented on Incentivize separating recyclable waste from trash.

Having worked for years on a college campus trying to introduce 4000 new people to waste sorting- this is a great idea- instant feedback. Great for young kids in school who will enjoy the game aspect.

Maybe for adults we can avoid the embarrassing fanfare and streamline this by a solar powered motor and flipper that sends waste to the right bin.

We will have to work on how to disassemble lunch bags and coffee cups!

Establishing a color coding system for products would really help get things in the right bins and communicate mixed stream assemblies.

For those not already familiar with the revolutionary paradigm of 'design thinking' - this MOOC is really enjoyable, with a simple and adaptable framework, and can be skipped through efficiently

Assuming a viable technology, design thinking would advance the state of the art depicted in the sunflower video, starting with the final scene shot of the spaced array of dishes in a sunflower field [understood to be an artistic device] in ways like these:

Recognize the spaced array as a familiar meme, a pattern we are familiar with and don't question, and close pack the array to save space, redesign the dish as a hexagon for perfect packing like a honeycomb, shrink the dishes and mount on a pole like brusssel sprouts [see http://www.allotment-garden.org/grow-your-own/brussels-sprouts.php ] , take these smaller dishes and mount them on cars and boats [not using concrete as a base this time], shrink them even smaller for carrying and expand functionality from lighting and heating to welding or battery recharge,, make them really small for tiny circuitry uses or chemical engineering platforms, ....

following the lead of theoretical physicists- we can think way forward to optimize technology before we invest in physical activity and become bound by time and money frictions!

I was inspired by the videos-and with this much good thinking around- we certainly can count on making progress..

Here are couple of conversation starters:
Revolutions in thinking and then action occur at change points- inflexions in curves = tipping points-

at or near the boundaries of zero and infinity,

and when we drop something altogether for something better- i.e. cell phones are the only phones in vast regions of the world-in the same way renewable energy is vastly superior to fossil fuel energy and will replace it as fast as we can think clearly about it- oops it just happened!

The Enron energy blackout/price gouging crisis ended overnight when people just remembered to conserve by turning out the lights - the rising demand faltered and energy prices dropped.

Imagine full transparency- nothing hidden-
