Capturing 'invisible' light from the sun to produce power
Most solar power devices are made from silicon, which cannot respond to light less energetic than the near infrared. So some parts of the light spectrum are going unused when it comes to solar power. But clever researchers at UNSW in Australia have worked out how to combine semiconductor quantum dots to absorb low energy light with molecular oxygen to transfer light to organic molecules - making it possible for normal silicon devices to operate.
One of the common ways to capture wave energy, is via a point-absorber which harvests energy from the up and down movement of waves. Australia's RMIT has designed a point-absorber with a novel counter-rotating dual turbine. The design can apparently deliver twice the efficiency of other currently available point-absorber wave technologies. https://www.rmit.edu.au/news/all-news/2021/aug/wave-energy-technology
One solution to power outages is the notion of power storage, instead of real time usage. The notion of energy storage can either be at utility scale, which includes all energy storages at the side of the utility provider, or energy storage can include behind the meter storage, which is all measures taken by households and industry to store energy or ultimately remote power systems which are supplied to remote areas that are not typically connected to the grid. Israeli companies are the leaders in innovation concerning energy storage, with expertise in hydrogen as well as mobile energy units. https://israeltrade.org.au/2021/09/23/the-future-of-storage-energy/
