Detail Description

Economical Geothermal Heating, Ventilation, and Air-conditioning

Maker of Innovative Energy-saving Geothermal HVAC System Seeking Marketing Partners. We are looking for business partners to market its patented and award-winning technology. (Exclusive, or non-exclusive)

The Geo Power System is a heating, ventilation and air-conditioning (HVAC) system that uses the earth's nearly constant underground temperature to passively warm or cool air for residential, commercial, or agricultural uses. The core of the system is a unique double pipe earth-to-air ground heat exchanger installed vertically in the ground to a depth of about 16 ft (5 m) - 25 ft (7.5 m). In most applications the system includes a cobblestone layer in the building foundation for further temperature control.

The Geo Power System is the geothermal HVAC solution that:
*Moderates temperature differences up to 18 degrees F (10 degrees C)
*Lowers heating and cooling bills
*Purifies indoor air, removing 95% of dust and 99% of pollen
*Includes automatic air circulation and ventilation
*Naturally controls humidity
*Operates in an entirely chemical-free environment
*Reduces CO2 emissions

With low operating and maintenance costs and no compressors, chemicals, or burners, the Geo Power System is a safe and economical component of green buildings. At home, this means greater comfort, health, and security for families. In a business context, it may translate into fewer hours of absence and greater productivity, which could be even more significant than the energy savings gained. In short, the Geo Power System provides natural comfort that is good for the environment, people, and their wallets.

As of 2018 the system has been installed in more than 1500 houses and more than 500 schools, commercial properties including factories, and other low story buildings in Japan. It was included in a Japanese government pavilion showcasing innovative environmental technology at the 2005 World Exposition in Aichi, Japan.

Among other awards, the Geo Power System won the Good Design Award and was included in the Japanesque Modern collection of distinctive products selected by the Government of Japan as exhibiting the union of Japanese culture, design, and aesthetics with advanced technology.

After establishing a track record at home, the company is now looking to expand into markets abroad. It is inviting companies to license its technology and know-how for distribution outside Japan. Under the company's business model, licensees will be free to promote, market, and install the system directly and sublicense it to their network of installers.

Proprietary components will initially be shipped from Japan, but we expect to arrange local production outside Japan in the future.

The path to partnership will be to first understand the above point. We will then need to have potential partners sign a non-disclosure agreement before we can disclose certain documents and data.

It is intended for the northern hemisphere and southern with almost the same latitude as Japan.temperatures exceeding 40 degrees celsius are not supported
