In 2020...

As more areas of the world adopt renewable technologies, scaleable energy capture and storage remains a struggle - even in solar-panel-filled California.

TL;DR

This spark is an exploration in understanding scale - specifically for urban and structural considerations in energy capture.

In 2050...

What sort of energy capture solutions will be available in the near-term future, and at what scale? In 2050, we may see the emergence of self-balancing microgrids, massive solar-capture blimps, and adoption of residential-scale wind capture. Large-scale energy storage and balancing solutions will enable

Ray and Charles Eames made an excellent visualization of scale in their Powers of Ten informational video. How might we apply the understandings of scale to energy capture solutions?

For example, how many solar panels might it take to power an entire country?
