PAHS - Umbrella House

PAHS - Umbrella House
Figure 1 Geodome, the first umbrella home (in idealized form), maintains a 66° to 74° temperature year-round without heating equipment in western Montana’s cold climate. In summer, solar heat radiates in, falls on internal surfaces, and is absorbed into the surrounding soil. The umbrella traps heat in the dry soil until winter, when it migrates back into the house. Adding convection-driven earth tubes would modify the internal temperature by conveying outside air in. Figure 2 Twenty feet under the surface, the soil temperature reflects the average ambient air temperature during the year. In effect, the umbrella raises this constant temperature zone to the surface and allows the house to warm it further. Figure 3a In summer, air enters the house through an earth tube and is warmed by the sun; moving through the second tube, it warms the cooler soil. Figure 3b In winter, cool air enters, is heated by the warm earth, and passes to the house. "What a marvelous idea!"

The Liberty House Umbrella Homes ... from Popular Science, August 1986, pages 64-66. This simple underground house design uses a novel insulating/water-shedding blanket that covers the structure and surrounding soil. The umbrella creates a huge subterranean thermal reservoir that soaks up the sun’s energy during summertime and stores it for winter heating. In many cases, the clever design makes a heating system unnecessary. The reverse can also be done for hotter climates. Hybrid Ventilation System - GreenGarageWiki From GreenGarageWiki return to Living Building Design Studio What is It? Hybrid ventilation is a building ventilation system that integrates natural (i.e. passive) and mechanical (i.e. active) ventilation components to create an high efficiency and healthy ventilation system for a building. An hybrid system can include: The rationale for a hybrid type system is to allow the earth's natural systems (e.g. the ground or wind) to do as much of the ventilation work as possible and only when they can not meet the required ventilation levels to resort to high-efficiency mechanical systems to complete the job.

Journal of Neural Engineering Dominique M Durand et al 2014 J. Neural Eng. 11 020201 Neural engineers have made significant, if not remarkable, progress in interfacing with the nervous system in the last ten years. In particular, neuromodulation of the brain has generated significant therapeutic benefits [1–5]. EEG electrodes can be used to communicate with patients with locked-in syndrome [6]. In the central nervous system (CNS), electrode arrays placed directly over or within the cortex can record neural signals related to the intent of the subject or patient [7, 8].

Earth formed. Earth sheltered structure. Then the shelter and surrounding earth bank is covered with an umbrella comprised of several alternating layers of insulation and polyethylene sheeting, extending beyond the perimeter of the structure 20'. The insulating, water-shedding, 'umbrella' itself is then covered with more earth sufficient to adequately support growth of vegetation for ground-cover. If heavy equipment is not available or affordable, it is feasible that the entire form can be hand-sculpted with only a shovel and other hand tools.

Earthtubing for sustainable, passive geothermal heating & cooling Earthtubes (earthtubing) are a most highly recommended low-tech, sustainable, non-electric, zero-energy, geothermal passive solar heating and solar cooling system. Earthtubing utilizes conventional, thin wall plastic sewer drain vent pipe to passively pre-heat your home's fresh air intake with zero-energy consumption. Filtered fresh air enters a series of non-porous pipes embedded around the interior of your home's foundation, absorbing energy from the surrounding soil, moderating the temperature of fresh air intake.

Mind Reading (Neural Decoding) Goes Mainstream Surfdaddy Orca November 9, 2009 In the new movie, The Men Who Stare at Goats, reporter Bob Wilton confronts Special Forces operator Lyn Cassady, “I’ve heard that you’re a psychic spy.” Eco-Dome: Moon Cocoon - Cal-Earth Building Designs The Eco-Dome is a small home design of approximately 400 square feet (40 sq. meters) interior space. It consists of a large central dome, surrounded by four smaller niches and a wind-scoop, in a clover leaf pattern. Learning and building an Eco-Dome is the next stage after building a small emergency shelter and provides hands-on learning experience in the essential aspects of Superadobe construction. Chrome tab backlog - Home in the Earth Well, it is September already and I am starting to seriously doubt that I will get this house started this year. Trying to get quotes has just been so frustrating. I have many quotes in, but not enough to be confident that I can get the house built for what I want to pay . Obviously, I don’t want to get started before I am sure I can afford to finish (Luke 14:28). During September, I will get back to pushing for quotes.

What is Geothermal? - Geothermal Resources Council Home > What is Geothermal? > Why Geothermal Geothermal Energy is heat (thermal) derived from the earth (geo) It is the thermal energy contained in the rock and fluid (that fills the fractures and pores within the rock) in the earth's crust. Calculations show that the earth, originating from a completely molten state, would have cooled and become completely solid many thousands of years ago without an energy input in addition to that of the sun.

OpenEEG project About the project Many people are interested in what is called neurofeedback or EEG biofeedback training, a generic mental training method which makes the trainee consciously aware of the general activity in the brain. This method shows great potential for improving many mental capabilities and exploring consciousness.

William Lishman Underground Achitecture Bill Lishman's unique underground house was the culmination of years of research and countless hours of design. Why build underground? There are many advantages to earth integrated architecture. Build-It-Solar Blog: Cristian's Earth Sheltered Passive Solar Home in Romania Cristian is an engineer in Romania, and has designed, built, and lived in this passive solar, earth sheltered house for two years. The house is very carefully laid out to make maximum use of space and and the solar heating and lighting opportunities. The house features:Earth sheltering on three sides with a carefully designed PAHS style insulation umbrella that uses the surrounding earth for thermal storage.Passive solar gain through the south triple glazed windows.Active solar through several Trombe walls integrated into the south wall.An extensive earth tube system that pre-heats incoming fresh air and recovers heat from outgoing stale air.A carefully designed back up wood heating system.Solar water heatingProvisions for solar electricity.The house is located at 45 degrees north latitude and has a serious winter -- the total heating bill for the past two winters has been $70 worth of wood -- about 0.6 cords.
