READY FOR SOME WILD IDEAS ABOUT SUSTAINABILITY?

Shade and rain for drought-stricken crops.

Here is one for Goodyear and/or DARPA:

Crops being ruined by drought and heat? I fear that the world will turn to geo-engineering the result of which we are not able to predict with accuracy. For example: Seeding the atmosphere with light-reflecting particles. If this does not work as expected, can the experiment be reversed? Better to have solutions that can be humbly removed from sight and withdrawn from action.

Perhaps there is another solution, more mechanical in nature and reversible. What if we created a cloud of hydrogen dirigibles and positioned it over a crop field to shield it from the burning rays of the sun? The 'cloud' would provide shade and if the crop required water, then a remotely controlled spigot on top of each dirigible would open, the flared hydrogen would be lit remotely by an electronic ignitor, creating 'rain' that would fall on the parched crop. We cannot drink oil or natural gas but we can turn them into water.

Venting heat out of the lower atmosphere.

Solution for geo-engineering the earth's temperature.

Here is one for Elon Musk:

Place in geo-stationary earth orbit above a hot zone (like the Mediterranean) a giant object (like the Space Station) and construct a giant tube that will hang down towards the earth's surface. An exhaust fan on the bottom end of the tube slowly starts to push the warm air up the tube towards the upper atmosphere. Soon warm air nearer to the earth's surface is rushing up the tube by convection. When the desired amount of hot air has been exhausted, close the bottom end of the tube. If the tube is manufactured from darker coloured plastic film, then it will absorb heat from the sun which will create even more of a convection action.
