A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The UT Austin technique is aimed at the latter.

Researchers combining CO2 storage and geothermal energy production

Green Car Congress

Between five and ten percent of the water injected in these systems is lost as it travels through the pore spaces. As this happens, more water must be added, perhaps from municipal sources that have little to spare. Their work has shown that supercritical CO 2 is better than water at mining heat from the subsurface.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons. The gravity batteries described in this story lift giant weights in the air or up mine shafts to store excess electricity, releasing the weights later on to recover the stored energy.

These great masses store enough water to raise global sea level by 65 meters should they melt entirely. Although neither ice sheet is expected to melt completely anytime soon, their incredible scale makes even small changes consequential for the future of our planet.
