A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into …

Biogas can be seen as a flexible and storable energy carrier, capable of absorbing intermittent energy production and demand. However, the sustainability and efficiency of biogas production as a flexible energy provider is not fully understood. This research will focus on simulating biogas production …

This document presents the investigation of the costs of investing in a new transformer compared to the maintenance of an existing one. A detailed research of the different technical possibilities to maintain transformers has been conducted. Superconducting Magnetic Energy Storage (SMES) technology had …

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 Dutch greenhouse horticultural industry is characterized by world leadership in high-tech innovation. The dynamics of this playing field are innovation in production systems and automation, reduction in energy consumption and sharing limited space. However, international competitive advantage of …

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. …

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 …

In dit hoofdstuk wordt ingegaan op de toepassing van vraagpatronenonderzoek als middel om formele en informele ondersteuning te verbinden. Hierbij wordt nadrukkelijk niet alleen gekeken naar zorg, maar ook naar meer brede vormen van ondersteunende activiteiten waar burgers van profiteren en in participeren. …

De noodzaak voor docentprofessionalisering is in dit tijdschrift al veelvuldig beschreven. Daarbij ligt het accent vaak op het individu. Maar juist collectieven zoals kenniskringen en lectorarten hebben een bijzonder vermogen om samen te leren. Het instellen van een kennisgemeenschap, zoals een Community …
