Sunspots

Sunspots: Collected Facts and Solar Fiction (1975) is a solar-energy and appropriate-technology primer by Steve Baer of the Zomeworks Corporation, illustrated by the Criss-Cross Art Workshop. Using everyday analogies — the earth as an orange orbiting a grapefruit sun, windshields, shadows — it explains solar geometry, energy units, and hands-on collector, heat-pipe, and Skylid designs.

Sunspots

Different layers of the sun are at different temperatures, but the sun radiates heat much like a body at 10,000° F. … If it is heavily cloudy, very little of the sun's radiation reaches the earth.

A 1975 Zomeworks Corporation book by Steve Baer (the dome/zome and solar-energy pioneer, author of Dome Cookbook and Zome Primer), illustrated by the Criss-Cross Art Workshop and dedicated to Theodore Baird. Though catalogued here within the broader Fuller/buckyverse corpus — Baer's zome geometry and the appropriate-technology counterculture grew out of the same geodesic milieu — Sunspots is Baer's own work, not Fuller's. It blends "collected facts and solar fiction": plain physics explained through homely models, interleaved with practical solar hardware.

Structure

Eleven chapters move from celestial geometry to buildable solar technology:

  1. The Sun — solar radiation, the earth's elliptical orbit, the 23½° axial tilt and the seasons, shadows, and "The Sun Riots" (sunspots). Includes the signature sections "The Earth Is an Orange and the Sun Is a Grapefruit," "Morning Front Windshield — Evening Back Windshield," "Autumn on Uranus," and "A Shadow Gives the Date."
  2. Energy — energy in a car crash, energy units, dams/hydroelectric stations, "A 50 Watt Dog," "Portrait of a Gasoline Drinker," "How Much Is One Man Worth?", sunlight, and mechanical equivalents of solar energy.
  3. Basic Technology — science and technology.
  4. Bubbles, Water, Heat Pipes — bubble machines, bubble solar collectors, refractive indices, a stock-pond melter, a new kind of heat pipe.
  5. Heat Exchangers.
  6. Heat Collectors and Houses.
  7. Flat Plate Collectors.
  8. Air Loop Rock Storage Systems.
  9. Engines.
  10. Skylids — Baer's insulating louver invention.
  11. Solar Energy Conferences.

Core ideas

  • Solar geometry made tangible. Baer admits he "always found it difficult to imagine the earth as an orange moving around the sun which is a grapefruit," and that the page-sized dot of the sun is really the grapefruit — using faith in science, Magellan, and the earth's shadow on the moon to bridge intuition and fact.
  • The orbit's real numbers. The earth's path is a mild ellipse; closest approach is 91,350,000 miles and farthest 94,455,000 miles, a 3.4% distance difference producing about a 7% swing in radiation intensity (which falls with the square of distance). Earth is nearest the sun in January, farthest in July; it spends about 186 days with the sun north of the equator and 179 days south, making Southern-Hemisphere summers shorter and warmer (an imbalance masked by that hemisphere's ocean cover).
  • Tilt creates seasons. The 23½° axial tilt — not orbital distance — drives the seasons; a table gives the sun's declination (degrees above/below the equator) on the twentieth of each month, and a cast shadow can therefore "give the date."
  • Other worlds, other relationships. "Autumn on Uranus" contrasts the solar relationships of other planets, whose extreme tilts and orbits make seasons unlike Earth's.
  • Energy literacy and appropriate technology. The later chapters translate abstract energy units into human-scale images (a dog as a 50-watt source, a person's worth in energy) and then into do-it-yourself solar hardware — bubble and flat-plate collectors, rock-storage air loops, heat pipes, engines, and Skylids.

Significance

Sunspots is a document of 1970s appropriate-technology and solar-design culture from Zomeworks, one of the movement's key New Mexico workshops. Its pedagogy — explaining hard celestial mechanics through oranges, grapefruit, windshields, and shadows, then handing the reader buildable solar devices — parallels the Fullerian aim of making science graspable and resource-efficient, which is why it sits alongside Fuller's works in this corpus despite Baer's distinct authorship.
