Energy flow through the lower extremities in high school baseball pitching

It is generally accepted that most of the energy transferred to the ball during a baseball pitch is generated in the trunk and lower extremities. Therefore, purpose of this study was to assess the energy flow through the lower extremities during a baseball pitch. It was hypothesised that the (stabilising) leading leg mainly transfers energy...

Active Control of Irreversible Faradic Reactions to Enhance the Performance of Reverse Electrodialysis for Energy Production from Salinity Gradients

Irreversible faradic reactions in reverse electrodialysis (RED) are an emerging concern for scale-up, reducing the overall performance of RED and producing environmentally harmful chemical species. Capacitive RED (CRED) has the potential to generate electricity without the necessity of irreversible faradic reactions. However, there is a...

Exergy and Sustainability: Insights into the Value of Exergy Analysis in Sustainability Assessment of Technological Systems

A major challenge in striving for a more sustainable society is the selection of technological systems. Given the capital intensity of industrial production plants, power generation systems and infrastructure, investment decisions create path dependencies for decades to come. It is difficult to know which technological system is preferable when...

Developing Attractive Power Plant Portfolios under Long-term CO2-price Uncertainty

Portfolio theory is one of the few convenient theories for analyzing portfolio investments in electricity markets. Originating from financial markets the application of portfolio theory however showed to have difficulties in dealing with the complexities existing power markets. Especially the introduction of CO2-prices caused problems that could...

Sustainability assessment of power generation in combination with lng evaporation: A comparison of lca methods and exergy analysis

Several options exist for power generation, but it is difficult to determine which option is the most sustainable. When assessing the sustainability of an option or system, it is important to consider the environmental, economic and social aspects of sustainability and to take a life-cycle point of view. According to literature, a relationship...

A supply demand model for exploration of the future of the Dutch gas sector

Import dependency and the extent of renewable gas production are two outcomes of interest concerning the future of gas supply in the Netherlands. Due to the complexity of internal mechanisms and uncertainties associated with the natural gas production, the production of renewable gases, and the demand for gas, the future of these two outcomes of...

Finite Element Analysis of a Kite for Power Generation

The kite is modelled with the non-linear finite element method to stay close to its physical properties and represent its full non-linear flexible behaviour. The inflatable beams in the leading edge and struts are modelled with regular beam elements that represent the behaviour to reduce the amount of degrees of freedom drastically. The canopy...
