Grundfos’ LifeLink system is used as the platform for the implementation of this idea. There is a potential in collecting the solar energy over a specific area (using solar reflector shields) and concentrating the available UV fraction (UV-A light) in a small area, leading the wavelength/energy in its original form via optical fibres to a treatment zone in the Lifelink setup. This is relevant as an additional water disinfection system, if the groundwater becomes contaminated or if LifeLink is implemented where only surface water is available.

Our vision is to collect solar energy and reduce air-condition cost by circulating water in windows. The water flows through the windows a thin laminar flow and absorbs infrared radiation from the Sun. The absorption is effectuated by an infrared absorbing coating applied to the window. The construction allows less light to enter the building reducing the need for air-condition. Using a heat conversion system, the captured thermal energy is usable for heating water, for the air-condition system or as electrical energy.
To ensure clear and clean water there is a need for purification, which can be achieved by ceramic filters removing particles and by TiO2 nano-particles for effective cleaning by photo catalysis. Sensor, valves and pump technologies are used for connecting the windows in a given building in order to have full control of the flow and ensuring security for the user.

The Clean Development Mechanism was introduced with the Kyoto protocol. It allows private companies to create CO2 reducing projects in foreign countries. In return they receive CO2 credits that can be used to the firm’s reduction requirements or be sold on a CO2 credit exchange.
Grundfos should establish an independent subdivision, Grundfos Climate (GFC) to locate projects where Grundfos technologies can reduce CO2 emissions. GFC will locate projects and do all necessary investigation and application and get projects approved. GFC buys technology needed from Grundfos and either donate it or sell at cost to consumer. In return GFC will earn annual CO2 credits and potentially service payments. The credits are sold at a Credit exchange and substantial profit can be made.
