Rings of Uranus one of which, Mab, shares its orbit with the outermost newly discovered μ ring. As currently understood, the ring system of Uranus comprises thirteen distinct rings. In order of increasing distance from the planet they are: 1986U2R/ζ, 6, 5, 4, α, β, η, γ, δ, λ, ε, ν, μ rings. They can be divided into three groups: nine narrow main rings (6, 5, 4, α, β, η, γ, δ, ε), two dusty rings (1986U2R/ζ, λ) and two outer rings (ν, μ). The rings of Uranus consist mainly of macroscopic particles and little dust, although dust is known to be present
Solar power in Australia the state government announced a new round of finance for renewable energy projects which included a Planet Arc Power - Schneider Electric development of a $13.9m solar PV and battery project at a major distribution centre in Adelaide’s North. The project includes a micro-grid management system optimising 5.7MW of solar PV coupled with 2.9MWh of battery storage. The University of South Australia will develop 1.8MW of ground and roof mounted solar PV at its Mawson Lakes campus. At the Heathgate Resources Beverley mine there are plans for a relocatable 1MW of solar PV paired with a 1MW/0.5MWh battery which will
