Rent Solar. Give Australians the opportunity to use solar energy to power their lighting and small appliances in units without the need to install permanent facilities, leveraging technology that already exists and is used in other countries.

Establish a 'Health Card' for the planet, to give a better projection on what is left, how long we have, what are the limits, how to change, what changes are best and at what levels. Every hectare of land on the planet would be given a number and assigned value. Each hectare to be graphed and graded according to emissions, carbon sequestrations, biodiversity, human population, etc, using drones and satellite imagery. Ultimately giving a health report for each hectare of the planet. All shorelines to record change in sea level and events added to each hectare as they occur. Everyone could have access to it and see how their areas are, 'Health wise', and possibly want to create change. It could also assist carbon markets, education, research and the economy.

Offered 3 solutions, in summary: A) ensuring pathways for recycling all materials: all goods manufactured having a microchip identifying the parts and materials used, to help with replacement of faulty parts and a 'smart bin' (with a solar-powered comms unit in lid) would alert council when the bin is full and alert recycling companies that certain materials are available, for potential purchase. B) all houses having water tanks plus solar panels, wind turbines, and small hydro electric generators fitted to gutters when it rains, with all energy feeding into batteries. C) electric cars providing additional battery storage, cars being charged by renewables at home and workplaces.

My idea is to encourage companies like Jim’s mowing to go all battery 🔋 on their mowing equipment. My other idea 💡 is to get all surf clubs around Australia to use electric IRB’s (surf lifesaving Australia).

Electric buses to replace every single bus with a petrol or diesel engine. The bus would have a charger that would charge the bus over night, but there would also be a hydrogen tank that would start producing electricity as the battery gets lower in the bus. This would prevent the bus from running out of battery and slow down the cause of climate change!

Tackling climate change one step at a time…Educating the next generation of custodians by immersing them in the wonders of the natural world. Developing respect and admiration for what nature has been producing for billions of years and delicately opening their eyes to what is at stake due to our actions from the last 200 years.

Reducing our waste stream and being energy efficient such as recyclable museum maps and sensor lights for each room to reduce energy consumption. If a leading museum such as the Australian Museum adopted this, the public would see you leading by example.

Conservasphere (summary): vast domes placed in arid and semi-aris areas, capturing solar energy, water captured from air (with Calcium Chloride) for growing plants, reducing Co2 and augmenting agricultural production.

Solar dome desalination plant (summary): desalination plant in the desert, using solar power to convert salt water piped from the ocean, to grow plants, green the desert.

A basic electric vehicle chassis that can take different body types example van, ute light trucks and people mover. A motor in front and rear axles. The battery pack on a tray that slides into the space between. Battery pack can be installed and removed by fork lifts. These vehicles can be use by councils couriers and most city bound trips with a range of 300 to 500ks. Manufactured in Australia, sold to councils.

Grow hemp as it can absorb carbon, grows fast, can be used for hand oils, clothes, building products, plastic replacement, medical use etc.
