ToSee Watchman Wi-Fi Video Solar Security Camera. LAVO, UNSW develop world's first domestic hydrogen battery. Unlike other lithium batteries, it can also constantly recharge itself rather than waiting until it has been fully discharged.
He said the system, which costs around $34,000, has a lifespan around three times longer than current lithium batteries and should last users around 30 years. When the hydride is degraded it can be melted down and reused, giving the system significant environmental advantages over its competitors. Because the hydrogen is stored in a solid state inside the hydride, the system avoids the risks of fire associated with hydrogen stored under pressure or in liquid form.
The LAVO battery system is already available on the market. The battery would not only act as a hot water service but act as something like a domestic power bank, with users able to remove cylinders of charged hydride from their own units to power household items such as the barbecue and bicycle.

Taiwan-based solar PV manufacturer Winaico has announced that it will launch its new Gemini module range on the Australian rooftop solar market in February, with module efficiency topping 20.62%.
The roll-out was announced by Winaico last week and will introduce two new PV modules, including the company’s most powerful, to date, the WST-375MG, which the company says is “ideal for most commercial applications.” Winaico says improvements in cell technology in the WST range have increased the power by more than 13%, to offer 375 Watts of power per module and “market-leading” efficiency of 20.62%. The second Gemini series module to be rolled out next month is the WSP-333MG, which Winaico describes as “an installer focused” panel that offers higher efficiency cells in a compact design. This 333W module offers 20.27% efficiency as well as a toughened frame and is optimised for small roofs, making it ideal for a 6.66 kW system size on residential installations.
Solar-powered airconditioning arrives in Australia. It sounds the most gloriously simple idea far too good to be true – solar-powered airconditioning.
But now it’s possible to harness the free power of the sun to cool your home with the release in Australia of a system specially designed to suit local conditions. “It’s just so neat,” says one of the first adopters, Sydney GP Dr Caroline Rogers. “The sun comes up, it feels a bit hot and immediately the airconditioning comes on. I love the idea of turning the heat from the sun into cool air. “And for winter, it’s reverse-cycle, so it’ll be as warm in winter as it is cool in summer.” Dr Rogers, 51, and her husband Tim, 53, were looking for a way of cooling the uncomfortably hot study on the upper floor of their two-storey Manly house after Tim started working from home during the pandemic.
As well as being marketed to people in the cities, it’s also being seen as a boon for rural communities that have previously been unable to install airconditioners due to poor power grid infrastructure. ‘Water battery’ a winner for Australian university. In the first year of operation, the thermal energy storage tank saved 4,232 tonnes of CO2 emissions – with 3,082 tonnes saved by the University of the Sunshine Coast through using solar power instead of grid electricity, and the rest by feeding solar energy into the grid.
December 30, 2020David Carroll From pv magazine Australia An award-winning Australian solar-powered “water battery” has been lauded as an unmitigated success with figures from the University of the Sunshine Coast (USC) revealing the system generated more than 3 GWh of electricity in its first 12 months of operation. The thermal energy storage tank, located at USC’s main campus on Queensland’s Sunshine Coast, is powered by a 2.1 MW solar PV system which produces enough energy to cool 4.5 megalitres of water, effectively acting as an 8 MW battery.
Environmental solutions company Veolia built the three-story high tank and installed more than 6,500 solar panels across campus rooftops and carpark structures. Aus Wind and Solar.
