Business-as-usual approach threatens world energy supplies and environment, but affordable, effective solutions appear within reach
Implementing a plan to keep rising carbon dioxide levels from reaching potentially dangerous levels could cost less than 1 percent of gross world product as of 2050, a cost that is well within reach of developed and developing nations alike. However, without simultaneous progress in the way energy is found, transformed, transported and used, the world is in danger of facing a severe energy crisis sometime within the next century.
Those are the conclusions of a report by Klaus S. Lackner and Jeffrey D. Sachs of The Earth Institute that appears in the most recent issue of Brookings Papers on Economic Activity published by the Brookings Institute.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
