Deezer was to give unlimited access to music lovers through streaming technology. The site in its original incarnation was charged with copyright infringement by French agency SACEM, and after being shut down in April 2007 was relaunched as Deezer in August 2007, having reached an agreement with SACEM to pay copyright holders with revenue from advertising on the site and by giving users the ability to download songs streamed on Deezer from iTunes, with Deezer receiving a commission from each purchase. At the time of its launch in 2007, Deezer had not yet negotiated agreements with major music labels and therefore
Tidal heating Tidal heating Tidal heating (also known as tidal working or tidal flexing) occurs through the tidal friction processes: orbital energy is dissipated as heat in either the surface ocean or interior of a planet or satellite. When an object is in an elliptical orbit, the tidal forces acting on it are stronger near periapsis than near apoapsis. Thus the deformation of the body due to tidal forces (i.e. the tidal bulge) varies over the course of its orbit, generating internal friction which heats its interior. This energy gained by the object comes from its gravitational energy, so over time in
