A new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …

Transitions in health care and the increasing pace at which technological innovations emerge, have led to new professional approach at the crossroads of health care and technology. In order to adequately deal with these transition processes and challenges before future professionals access the labour …

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 …

Het betreft een artikel in het maandblad Geografie. Deel 3 van de serie Nederland in 12 delen. Naar buiten toe stralen Tukkers een en al saamhorigheid uit. Maar het moderne Twente is een vat vol tegenstellingen: tussen stad en land, tussen trend en traditie, tussen samenwerking en tegenwerking. Je kunt …

It’s clear that the e$ective management of design is a commercial necessity. It enables a company or organization to innovate, to stay in line with or ahead of the market, and to identify and cater to consumer needs. When design becomes an explicit part of the management process, it can have a greater …

De kennisagenda ‘Psychische gezondheid, een maatschappelijk belang’ is een uitwerking van een convenant tussen ggz Nederland, ZonMW en het Trimbos-instituut met de intentie tot samenwerking in het kader van kennisbeleid. De kennisagenda moet ‘coördinatie en sturing’ teweegbrengen op het gebied van kennisbeleid; …

It is often said that European companies must stop trying to compete on price and concentrate more on developing products and services that offer customers and users a high level of added value. Design is an indispensable tool for such development and innovation, and this is why the findings of this …

Performance results are given of a new type of greenhouse, which combines reflection of near infrared radiation (NIR) with electrical power generation using hybrid photovoltaic cell/thermal collector modules. Besides the generation of electrical and thermal energy, the reflection of the NIR will result …

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 an previous research project a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed which has an integrated filter for reflecting the near infrared radiation (NIR) to the greenhouse and exploiting this radiation in a solar energy system. The performance of …
