Jeri Ellsworth demonstrates a PMOS transistor she fabricated herself in a home chip lab. She shows some of its electrical characteristics.

Kirsten Dirksen tours the underground ferro-cement dome home of Paula and Bill Lishman, the family behind the geese-led flight story. The skylit earth-sheltered house stays warm below the frost line.

A KOMO News documentary about Seattle's homelessness, addiction and street crime. It examines the City Council's policies, shows conditions on the streets and the impact on local businesses, and explores possible solutions.

Ben Felix explains how to decide between renting and buying a home, weighing financial and non-financial factors. He argues that renting is often as good or better than owning, both financially and for well-being.

Technology Connections explains how a home can act as a thermal battery by pre-cooling or pre-heating when electricity is cheap or abundant. He shows how this shifts load off-peak and eases strain on the grid.

Tech Ingredients shows how to build a liquid panel with a specialty paint that, placed outside, cools below ambient air temperature. It demonstrates radiative sky cooling.
