About Lloyd Kahn
Lloyd Kahn started building his own home in the early '60s and went on to publish books showing homeowners how they could build their own homes with their own hands. He got his start in publishing by working as the shelter editor of the
Whole Earth Catalog with Stewart Brand in the late '60s. He has since authored six highly-graphic books on homemade building, all of which are interrelated. The books, "The Shelter Library Of Building Books," include
Shelter,
Shelter II (1978),
Home Work (2004),
Builders of the Pacific Coast (2008),
Tiny Homes (2012), and
Tiny Homes on the Move (2014). Lloyd operates from Northern California studio built of recycled lumber, set in the midst of a vegetable garden, and hooked into the world via five Mac computers. You can check out videos (one with over 450,000 views) on Lloyd by doing a search on YouTube:

That thing rocks. Could use it to commute in snowy New England these days.
Why has this passed into history? It seems that it would be a viable alternative to tracked snowmobiles.
I though this would be impossibly retro, but actually it's an extremely clever design.

have to agree, it seems to work very well, with many features. seems sturdy and stable. how does it maneuver/handle compared to a "modern" snowmobile?
