Abstract: Geothermal power plant, comprising units that are modularized and adapted in order to fit into one or more container, as a geothermal container unit, the geothermal container unit is dimensioned in order to be adapted to extract geothermal energy from one drillbore, and each geothermal container unit has means for being electrically connected to other geothermal container units as well as electric power network, thereby providing a geothermal power plant arranged in a network providing load balancing and redundancy.

Abstract: Current busbar for anode or cathode for use in production of aluminium from alumina in an electrolysis bath in an electrolysis cell, comprising ends or sections that during operation shall be within the electrode body are formed as horizontally oriented conical bodies and cylindrical or conical grooves with largest horizontal cross section dimension within said grooves, such that by sliding in correspondingly formed cooper rails on the external parts of the busbar, said bodies and rails are releasable joined.
