Going Solar
by Txchnologist staff
This graphic shows the many ways that homeowners can tap the sun to power domestic bliss. Suggestions run the gamut from modern contrivances like solar water heaters and light tubes to tried-and-true clotheslines and shade trees.
Rocky Mountain Institute, a think tank focused on resource efficiency through integrative design, includes the average payback for solar upgrades in its graphic. This is a very general measure of when cost savings through using solar energy versus conventionally purchased grid electricity pays for the cost of the system and financing.

Packing Light

by Txchnologist Staff

The job of manufacturing incandescent lightbulbs was captured in 1935 as part of an educational film series produced by GE called Excursions in Science.

The women at top were packing recently manufactured bulbs for shipment, the final stage of a long and exacting production process.

The animation below shows an earlier part of the process, when the bulbs’ flanges were made from glass tubing. Intense heat softened the bottom of the tube and a spinning mold created a beveled edge.

Architecture Of The Night

by Txchnologist Staff

GE printed this booklet, Architecture of the Night, in February 1930. Published while the art deco style was sweeping around the world, the booklet’s articles suggested all the possibilities of architectural illumination for the growing stock of beautifully executed buildings.

New Materials Could Mean Natural Lighting from LEDs

by Michael Keller

We’re at the beginning of a new lighting revolution—the world is slowly switching over from the energy hogs of the last century to efficient light-emitting diodes (LEDs).

But the goal of making a LED bulb that produces warm, white light is still the subject of intense research. It turns out that creating materials that can emit a broad spectrum of wavelengths mimicking natural light is a tricky business.
