A new tool developed by researchers from The Australian National University (ANU) shows the best locations around Australia that could be used to build new wind or solar farms.
Concentrating solar thermal systems are still little known in Germany, although they are a highly efficient approach to producing heat from solar energy. In such a system, specialised mirrors arranged in different geometries are used to focus the Sun’s rays on a defined area, such as a circle or a line. This heats a heat transfer medium, which then flows through a heat exchanger.

Siemens Gamesa was looking for a 3D scanning system to take exact, agile measurements of wind turbines and their components so that they could be analyzed and processed using CAD software. The main goal was to dispense with traditional and inaccurate measuring tools such as tape measures and gauges, in favor of a more agile and precise method.
How can you spot emerging technology innovation at public companies? And how could you scale this up, so that you could track not just a handful but hundreds or even thousands of companies? For this article, I analyzed more than 650,000 financial news to find out.
