Question: What year was the film made that was about the inventor of a type of passive solar house that is made of both natural and upcycled materials such as earth-packed tires?

Context paragraphs:
Passive solar building design: In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.  This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.

Mike Reynolds (architect): Michael E. "Mike" Reynolds is an American architect based in New Mexico, known for the design and construction of "earthship" passive solar houses.  He is a proponent of "radically sustainable living".  He has been a critic of the profession of architecture for its adherence to conventional theory and practice, and he advocates the reuse of unconventional building materials from waste streams, such as automobile tires, and is known for designs that test the limits of building codes.

John I. Yellott: John I. Yellott (October 25, 1908 – December 30, 1986) was a scientist internationally recognized as a pioneer in passive solar energy, and an inventor with many patents to his credit.  In his honor the American Society of Mechanical Engineers (“ASME”) Solar Division confers a biannual "John I. Yellott Award" which "recognizes ASME members who have demonstrated sustained leadership within the Solar Energy Division, have a reputation for performing high-quality solar energy research and have made significant contributions to solar engineering through education, state or federal government service or in the private sector."

Garbage Warrior: Garbage Warrior is a 2007 film about architect Mike Reynolds, inventor of the Earthship style of building, directed by Oliver Hodge.  It follows Reynolds and how he developed the Earthship style of building and his struggle with the laws of Taos, New Mexico, the location of his experimental Earthship community, in order to be allowed to build homes that do not match the structures of local building codes.  The film concludes with a postscript showing Reynolds and his team of builders travelling to the Andaman Islands in the aftermath of the Boxing Day tsunami to assist the locals with disaster recovery and teaching them how to construct extremely low-cost earthships.

Kenneth Haggard: Kenneth L. Haggard (born 1935) is an American architect, educator, and solar pioneer who has designed more than 300 buildings and seen more than 200 built.  He is a licensed architect in California and Florida.  He and his partner Polly Cooper were awarded the American Solar Energy Society Passive Solar Pioneer Award in 1996.  They have been leaders in both passive solar architecture and the rediscovery of straw bale building.

Earthship: An Earthship is a type of passive solar house that is made of both natural and upcycled materials such as earth-packed tires, pioneered by architect Michael Reynolds.

Solar architecture: Solar architecture is an architecture approach that takes in account the Sun to harness clean and renewable solar power.  It is related to the fields of optics, thermics, electronics and materials science.  Both active and passive solar housing skills are involved in solar architecture.

Low-energy house: A low-energy house is any type of house that from design, technologies and building products uses less energy, from any source, than a traditional or average contemporary house.  In the practice of sustainable design, sustainable architecture, low-energy building, energy-efficient landscaping low-energy houses often use active solar and passive solar building design techniques and components to reduce their energy expenditure.

Solar chimney: A solar chimney often referred to as a thermal chimney is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy.  A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.

Double envelope house: A double envelope house is a passive solar house design which collects solar energy in a solarium and passively allows the warm air to circulate around the house between two sets of walls, a double building envelope.  This design is from 1975 by Lee Porter Butler in the United States.
