Model calculations and the few data that are available show that over 100 L water condense yearly on each square meter of a greenhouse cover. It is known that the presence of condensate reduces light transmission. This effect is suppressed to some extent by adding film-forming (anti-drop) additives to …

The scope of this investigation is the development and testing of a new type of greenhouse with an integrated linear Fresnel lens, receiver module and an innovative system for tracking to exploiting all direct radiation in a solar energy system. …

Cost price efficiency is key in competing in the modern horticultural industry. Over the past four years I came to realize that bulb cultivation and the cultivation of bulb flowers is accompanied by major risks, as it is difficult to fine tune the product’s quality. Seasonal influences affect bulb growth, …

A new CPV system with a static linear Fresnel lens, silicon PV module suitable for concentrated radiation and an innovative tracking system is integrated in a greenhouse covering. The basic idea of this horticultural application is to develop a greenhouse for pot plants (typical shadow plants) which …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

Stichting Natuurlijk Genieten is a Dutch foundation, founded by Jeannette Bolck, and dedicated to stimulating the development of a more natural living environment for older people living permanently in residential care centres. Many older people, in particular with Alzheimer's, are dependent on activities …
