Geoengineering the planet

We are already geoengineering the planet by pumping CO2 into the atmosphere to raise the temperature and by cutting down and burning trillions of trees to make farmland plus a lot of other ways.
​It’s a dangerous practise that could be going to bring a lot of problems for humanity but here is one that might help farmers and is something to think about.

Picture
Australia is a country with a very flat and barren interior and I have often speculated what it would have been like If it had a range of mountains right down the middle, which would have created rain clouds to feed rivers and make the centre fertile and probably cooler. 
Constructing a wall high enough to do the same thing as a mountain is not an option but we could use a different technology.

Picture
The Spanish have been researching hot air thermal generators to make electricity and one of the side effects is that there has been noticed a downwind tear drop area of green growth. This is caused by the hot air rising from the chimney and pushing some moisture into the upper atmosphere where the moisture condenses and falls as rain.

Picture
If a line of big thermal chimneys were constructed and placed in a line down route A71 between Charleville and Bourke it would be close enough to the grid to take away the electricity and, in a farming region which is on the brink of productivity due to a lack of rainfall moisture, it could increase farming productivity substantially.
​
These chimneys are not wildly expensive to build and make cheap electricity but the real benefit would be to farming where even a small increase in rainfall would be a huge benefit. Instead of destroying farmland by digging coal, which is a diminishing energy source, and spending a billion dollars on a railway which would only be for coal movement the Queensland government would do better by looking at alternative investments.
It needs some research into its effect into the upper atmosphere but it could work.

A very interesting idea that could have mutual benefits for farming and energy. Around 1 year ago there was discussion and controversy around a serious idea to build an artificial mountain in the deserts of the United Arab Emirates, to attract rainfall and create a watershed effect. We've seen mountain tops removed for mining and forests cleared for plantations, ancient locked away greenhouse gases released, unintended careless geoengineering indeed. I worry at some of the ideas to control rising temperatures, like seeding the atmosphere. Best to throttle back on emissions and restore the rain forests, and a few hopeful ideas in scrubbing the CO2 from our atmosphere. But we're leaving it late, I sincerely hope not too late.

I see academics working on various ways to clean up our atmosphere - nothing yet produced on an industrial scale but I live in hope. But meanwhile keep on with restoring forests - it's our best shot.

UCF Professor Invents Way to Trigger Artificial Photosynthesis to Clean Air, Produce Energy.

A chemistry professor has just found a way to trigger the process of photosynthesis in a synthetic material, turning greenhouse gases into clean air and producing energy all at the same time.

The process has great potential for creating a technology that could significantly reduce greenhouse gases linked to climate change, while also creating a clean way to produce energy.

Hello Bob. When you consider that are putting 350 billion tonnes of CO2 from coal into the atmosphere a year and a simmiler aunt from oil removing it is an almost impossible task. We will have to attempt it but it is not going to be easy.
The ides of the chimnies is a bit frivolous but Australia is not blessed with a good environment because it is so flat and does not make rain to feed rivers. I also have a seeking feeling that pushing hot air into the upper atmosphere is not a good idea.

The one in Spain is at least partially built by Australians, as you can see from its video:

See EnviroMission Limited banner displayed in the video. The Australian version will be one km high, as you van see from its video:

Meanwhile, the United States is still taking hits from Mr Trump's coal jobs:

Coal mining jobs aren’t coming back. But clean energy is already creating millions of new ones
