Elon Musk’s Next Logical Move — Electric Airplanes — Modular Strategies for Sustainable Global MobilityPhoto by Leio McLaren on UnsplashIn Australia, Elon Musk built an electric battery plant that can back up the grid within milliseconds.And he’s losing money with it.Tesla’s 100 MW/129MWh Powerpack system near Jamestown, Australia provides backup power for South Australia’s energy grid. 30–40% of the electricity it provides goes unpaid because the grid only measures electricity pumped into the system a full 6 seconds after a breakdown event.The Powerpack farm responds in milliseconds: 0.14 seconds the last time it had to back up the grid.Why lose money instead of adding in an artificial 6 second delay?Because Elon Musk’s next project is beautiful.But it’s not about airplanes.Next project:Provide a (...)

Tesla’s Elon Musk offers to solve power crisis in South Australia | Reuters

Tesla Inc boss Elon Musk on Friday offered to save Australia’s most renewable-energy dependent state from blackouts by installing 100 megawatt hours worth of battery storage, valued at $25 million, within 100 days of signing a contract.
The offer follows a string of power outages in the state of South Australia, including a blackout that left industry crippled for up to two weeks and stoked fears of more outages across the national electricity market due to tight supplies.
Musk made the ambitious offer on social media, and the government said it could consider backing such a battery roll out by Tesla.
South Australia Police adopting facial-recognition technology

NEC Australia has been awarded with a AU$780,000 contract to deploy facial-recognition technology for South Australia Police. The South Australian government has awarded NEC Australia with a AU$780,000 contract to implement facial-recognition technology as of late October for the state’s police force in an effort to make it easier to identify persons of interest and missing persons. The facial-recognition technology allows police to compare images of suspects from such sources as (...)

Growing food in the desert: is this the solution to the world’s food crisis? | The Observer

the work that Sundrop Farms, as they call themselves, are doing in South Australia, and just starting up in Qatar, is beyond the experimental stage. They appear to have pulled off the ultimate something-from-nothing agricultural feat – using the sun to desalinate seawater for irrigation and to heat and cool greenhouses as required, and thence cheaply grow high-quality, pesticide-free vegetables year-round in commercial quantities.
Seawater Greenhouse: A new approach to restorative agriculture | Global Water Forum

There are now some 200,000 hectares of greenhouses around the Mediterranean, and over 1 million in China, where 30 years ago, there were almost none. This is because yields that are achieved in greenhouses can be 10 to 100 times greater than yields achieved outside. They also enable high value crops to be grown ‘out of season’.
The Seawater Greenhouse enables year-round crop production in some of the world’s hottest and driest regions. It does this using seawater and sunlight. The technology imitates natural processes, helping to restore the environment while significantly reducing the operating costs of greenhouse horticulture. In addition to not having to discharge concentrated brine, it also benefits from the fact that high salinity water has a powerful biocidal or sterilising effect on the air that passes through it. This reduces or eliminates airborne pests.
