Abstract: The invention provides a padlock assembly (10) which can be convertible between a “snap lock” configuration and a configuration where a key is required to lock the padlock. Padlock assembly (10) includes a cam (62) with asymmetrical driver engaging means (64). Cam (62) can be inserted in the padlock assembly (10) in either of two positions to provide dual functionality. The invention also provides the cam (62), a driver (50) and a shackle (36) for a padlock assembly.

Abstract: A climate control system according to implementations of the invention includes one or more vacuum chambers. The vacuum chamber is encompassed by a chamber wall that is substantially impervious to gases. The vacuum chamber houses one of several combinations. In one combination, the near vacuum has yet to be created, and the vacuum chamber houses substantially-pure carbon dioxide and un-reacted carbon dioxide reducing agent. In a second combination, the near vacuum has been created, and the vacuum chamber houses reaction products of a chemical reaction between substantially-pure carbon dioxide and carbon dioxide reducing agent in a near vacuum. Various methods are used for creating vacuum chambers and for generating near vacuum conditions within such chambers. Various systems and structures can utilize such vacuum chambers and panels containing such chambers.

Abstract: A modular wall panel system to facilitate modular home construction in remote locations. Each wall panel includes two complementary wall members secured in their relative positions via a panel slide lock. Each wall member is composed of layers of lightweight, thermal resistant insulation. The insulant layers are separated by reflective layers designed to attract and retain solar energy.
