Reducing the impact on fish populations by rethinking the traditional turbine design
While hydropower is emission-free, the use of traditional turbines can result in negative impacts on fish, especially migratory fish. Fast-spinning, traditional blades can cut them, sudden changes in pressure can kill them, as can being pushed through the turbine. But a new pin-wheel design turbine with blunt edges can act as "an airbag" and greatly improve the outcomes for fish. https://www.bbc.com/future/article/20200713-the-most-powerful-renewable-energy
There are over 1000 satellites with a mass over 150 kg needing to be launched annually by 2023 to specific orbits and there is just not enough capacity to get them up into space. Gilmour Space solve that problem, they are developing 2 launch vehicles to take 100 kg and 400 kg to Low Earth Orbit at a consistently cheaper cost than all known competition.Check out the AMGC project here https://www.amgc.org.au/wp-content/uploads/2020/03/GILMOUR-SPACE-COMPOSITE-RELEASE-FINAL.pdf
Graphene development company SPARC TECHNOLOGIES has demonstrated that its graphene product in solution can adsorb gold and silver from mine tailings dumps.Adsorption, not to be confused with absorption, is a process in which molecules are held loosely on the surface of an adsorbent.The company, which has licenced graphene-based technologies from the University of Adelaide,
has shown its product outperformed commercially available adsorbents,
opening up a large potential market treating minesite dumps.https://www.aumanufacturing.com.au/sparc-uses-graphene-to-extract-gold-from-tailingshttps://sparctechnologies.com.au/Feel free to reach out to me and connect here:
