April 2024

This newsletter starts with something different, namely translation of an
interview with Jens Beckert, Director at the Max Planck Institute for the Study
of Societies and Professor of Sociology in Cologne.
On the brighter side, it also includes a number of items on positive actions that
are helping improve people’s lives, and on technologies that can, or have the potential to contribute to reducing future emissions.
CONTENTS
– “How can we just go on living like this, even though we have known for three decades what is threatening us?”
– Ocean heating 2023
– Our reliance on fossil fuels
– “Plastics producers have deceived the public about recycling”
– How Burkina Faso builds schools that stay cool in 40C heat
– The African tree-planting project making a difference
– The ‘15-minute city’ has taken off in Paris
– UNSW team creates synthetic methane using only sunlight
– Printed solar cells
– Acqueous metal-ion batteries
– Energy storage using salt, air and bricks

Submission on Measures for Transition to an Expanded and Highly Renewable Electricity System

We recommend to commence work on a vision of how New Zealand will look without fossil fuels and then to develop a pathway how to get there. This consultation document assumes a great manufacturing effort over the next decades of power lines, power pylons, windmills, PV panels, electric cars, rail tracks and other infrastructure. This will all be done predominantly by using fossil fuels with associated emissions. It will also be done on the backdrop of diminishing resources of raw materials including crude oil. In terms of energy we are also dealing with a reduction of the ratio of Energy Returned On Energy Invested (EROI) while aiming to produce new infrastructure and trying to maintain or replace existing infrastructure all built with fossil fuels at a high EROI ratio.

Green steel

Steel is one of those materials that we cannot imagine a future without. Although there are some applications where wood based materials can replace it, its just such a useful material and it can be fully recycled, so surely there’s a way of producing it which doesn’t cost us the earth.

Opportunities for Real Transition Leadership

Grant provides a perspective on the challenges facing engineering as it engages in the broader transition and climate adaptation process. He has identified a number of issues and gaps that engineers need to address. The Real Transition Leaders programme and community seeks to close these gaps, and Grant offers an overview of the programme.
