Central solar heating Use of solar heat for district heating has been increasing in Denmark and Germany  in recent years.
The process is said to be more efficient than traditional machining. Electron Beam Melting involves shining a laser beam into a bed of titanium powder, selectively melting that powder to create fine successive layers of solid material that are fused together to form a single object.
All the powder that isn't melted can still be used for subsequent builds. By contrast, when parts are machined out of a solid block of titanium, more of the material ends up being wasted.
