Literally anything that moves is using energy that can be harnessed. Not just waves rolling toward shore but cars depressing roads, buildings swaying in the wind, and much more. One way to harness it is to create a material that can be woven into the fabric of roads and buildings so that it captures the energy and converts it into electricity. Caitlin McDermott-Murphy at NREL describes research into Hexagonal Distributed Embedded Energy … [Read more...]
Concrete supercapacitor: works like a battery, much cheaper, easy to make
Capacitors work like batteries. They store and discharge electricity. David Chandler at MIT explains how researchers there have designed a supercapacitor from concrete and carbon black, two cheap and common materials. The beauty of the idea is that they can be incorporated into building foundations, thus installing a battery virtually for free. A concrete capacitor cube 3.5m wide can store 10kwh, enough for a household. Similarly, concrete … [Read more...]
Understanding the new EU ETS (Part 2): Buildings, Road Transport, Fuels. And how the revenues will be spent
A fortnight ago we published Simon Göss’s explainer of the big changes happening to the EU’s Emissions Trading Scheme (ETS). That article covered the new rules coming in for the existing EU ETS, and the implementation of the new carbon border adjustment mechanism (CBAM). This article explains the introduction of an EU ETS II that extends emissions trading to the buildings sector, road transport and the usage of fuels in other, as of now not … [Read more...]
