Measuring greenhouse gases from space

Measuring greenhouse gases from space
Space agencies examine the extent of greenhouse gases in the air via prisms and gratings in satellites. The latest technology now makes it possible to connect both components with each other so that they are suitable for space thus achieving a new level of quality for spectral resolution. In addition to industrial CO2 emissions, agriculture also contributes significantly to climate change: above all methane (CH4) and nitrous oxide (N2O), which are released in large quantities due to livestock and fertilisation.

Tests show how trucks can reuse engine heat for power

Working with automotive manufacturer Scania, researchers from KTH Royal Institute of Technology have been testing semi trucks equipped with a system that converts exhaust heat into power — through a process called thermoelectric generation (TEG). The voltage produced by the system can power the truck and reduce the strain on the engine, explains researcher Arash Risseh.
