Cost projections for microwave plasma CO production using renewable energy

Successful deployment of renewable fuel production requires substantial cost reduction along the entire value chain of the underlying manufacturing routes. To improve their performance, renewable fuel pro duction technologies should follow a cost-reducing learning curve. In this article, we adopt recent evi dence that learning-by-doing is...

Adapting technology learning curves for prospective techno-economic and life cycle assessments of emerging carbon and utilization pathways

Comparisons of emerging carbon capture and utilization (CCU) technologies with equivalent incumbent technologies are necessary to support technology developers and to help policy-makers design appropriate long-term incentives to mitigate climate change through the deployment of CCU. In particular, early-stage CCU technologies must prove their...

Integrated assessment projections for global geothermal energy use

The use of geothermal energy is expected to grow rapidly over the next several decades at many places in the world, since geothermal resources are abundant, and because this renewable energy option is both a low-carbon and non-intermittent technology. With the integrated assessment model TIAM-ECN we quantify how large its growth could be until...

Evaluating learning approaches for product assembly Using chunking of instructions, spatial augmented reality and display based work instructions.

Augmented Reality (AR) as an assistive technology is a promising tool for novice operators to learn assembly processes. This experiment compared an AR instruction method to display based electronic working instructions (EWI) for product assembly, to assess learning during the first repetitions of the products. In addition, two types of work...

Evidence for effects of task difficulty but not learning on neurophysiological variables associated with effort

Learning to master a task is expected to be accompanied by a decrease in effort during task execution. We examine the possibility to monitor learning using physiological measures that have been reported to reflect effort or workload. Thirty-five participants performed different difficulty levels of the n-back task while a range of physiological...
