All over the world hundreds of thousands of initiatives are being developed to generate sustainable energy. The great majority of these are aimed at solar and wind energy, if only because they are available all over the world. Whats more, the initial investments required are relatively low and are often helped by government support, so even...

Watersheds can be characterized as complex space?time filters that transform incoming fluxes of energy, water, and nutrients into variable output signals. The behavior of these filters is driven by climate, geomorphology, and ecology and, accordingly, varies from site to site. We investigated this variation by exploring the behavior of...

The ‘Egg Model’ is a synthetic reservoir model consisting of an ensemble of 101 relatively small three-dimensional realizations of a channelized oil reservoir produced under water flooding conditions with eight water injectors and four oil producers. It has been used in numerous publications to demonstrate a variety of aspects related to...

TU Delft students are participating for the fourth time in the world championship solar boat race in Friesland, which begins on 8 July. Expectations are high because the TU Delft students were world champions in 2006 and 2008. In 2010, the solar boat was equipped with hydrofoils for the first time. Unfortunately, the hydrofoils caused the boat...

Governments, regulatory bodies and road authorities all push for and promote sustainability. Contractors respond with strategies to reduce their carbon footprints. Besides optimising their asphalt production and logistics processes, companies are investing in the development of low energy asphalt mixes. Warm Mix Asphalt (WMA) is such an asphalt...

By their very nature, Spin Waves (SWs) excited at the same frequency but different amplitudes, propagate through waveguides and interfere with each other at the expense of ultra-low energy consumption. In addition, all (part) of the SW energy can be moved from one waveguide to another by means of coupling effects. In this paper we make use of...

Buildings’ expected (projected, simulated) energy use frequently does not match actual observations. This is commonly referred to as the energy performance gap. As such, many factors can contribute to the disagreement between expectations and observations. These include, for instance, uncertainty about buildings’ geometry, construction, systems,...

Excess sewage sludge in wastewater treatment plants (WWTPs) is regarded the key energy source for achieving energy neutral WWTPs. The anaerobic digestion process transforms sludge-organic matter into methane, which subsequently can be used for heat and electricity production. Conventional anaerobic digesters (ADs) have been used for sludge...

Clustering techniques are of main interest for separation of partial discharge (PD) sources. The separation is achieved if it is possible to extract from the PD pulses specific information related to the source. In this sense, this paper explores the capability of fundamental quantities derived from PD current pulses such as the peak amplitude...

Calculating the environmental benefits of energy saving systems in dwellings in a life cycle assessment (LCA) has two major issues, namely: how to deal with the customer behaviour and how to deal with rebound effects. Both issues are important for sustainable strategies. From a user-centred design perspective, two fundamentally different...

Road transport offers important logistic benefits at a reasonable cost for producers and consumers, hence its large market share. But, its use of diesel or gas generates large volumes of Co2, nox and pm10 (among others). Higher emission standards and demand for greener transport call for alternatives. literature analysis, a simulated Dutch...

The present study aims to investigate the impacts of oil sands development in Canada on the economy, society and the environment as the three pillars of sustainability. Factors such as aquatic ecosystems, land disturbance and reclamation, air quality, public health, safety, aboriginal and local communities, gross domestic product, employment...

The key enabling factor for Spin Wave (SW) technology utilization for building ultra low power circuits is the ability to energy efficiently cascade SW basic computation blocks. SW Majority gates, which constitute a universal gate set for this paradigm, operating on phase encoded data are not input output coherent in terms of SW amplitude....

We propose a new approach for tracing value change. Value change may lead to a mismatch between current value priorities in society and the values for which technologies were designed in the past, such as energy technologies based on fossil fuels, which were developed when sustainability was not considered a very important value. Better...

Why are some groups of bacteria more diverse than others? We hypothesize that the metabolic energy available to a bacterial functional group (a biogeochemical group or ‘guild’) has a role in such a group’s taxonomic diversity. We tested this hypothesis by looking at the metacommunity diversity of functional groups in multiple biomes. We...

Spaces of ocean-borne energy logistics and their landside extensions around the North Sea have developed into specialised, impermeable structures of energy extraction, transportation, transformation and storage. Despite the irregular dispersal of artefacts, the combination of both fixed and mobile infrastructure weaving through the North Sea has...

A mitad is a type of stove used to prepare traditional Ethiopian flatbread called injera. Current electrical mitads are energy inefficient and account for over 8% of Ethiopia’s national electricity consumption. The Magic Mitad bakes high quality injeras and uses up to 45% less electricity. This will help bakeries and households to cut costs and...

Since the problem of global warming has been broadly considered as vital and due to constantly rising oil prices, further fossil fuels exploitation requires diametrical changes immediately. The demand for environmentally friendly improvements does not only entail searching for new resources but also utilizing those which are available and more...

Cellular solids are characteristically excellent energy absorbers due to their capacity to store large amounts of energy through compression. A bioinspired design approach identified the Pomelo fruit (Citrus Maximus) as a biological role model for energy absorption. Fruit peels’ biologically most important functions lies in the need to provide...
