Plowing Carbon Into the Fields

5 Tractor Exhaust into Ground 653

Plowing tractor exhaust into the field, eliminating fertilizer costs

A wheat farmer in Australia has eliminated adding fertilizer to his crop by the simple process of injecting the cooled diesel exhaust of his modified tractor into the ground when the wheat is being sown. In doing so he eliminates releasing carbon into the atmosphere and at the same time saves himself up to $500,000 (AUD) that would have been required to fertilize his 3,900 hectares in the traditional way. Yet his crop yields over the last two years have been at least on par with his best yields since 2001. The technique was developed by a Canadian, Gary Lewis of Bio Agtive, and is currently in trial at 100 farms around the world.

Silver Glasses For The World’s Poor

Silver Glasses For The World’s Poor 

We revere Santa Claus as our mysterious giver of gifts, but the rest of the world may reserve that spot for Josh Silver. Professor Joshua Silver, to be specific – a retired physics teacher at Oxford University who has developed “Silver Glasses,” which are tunable spectacles that need no optometrist to adjust. That’s because the glasses have syringes filled with silicone liquid connected to each lens, and the wearer only has to inject or suck out the fluid until the view through the lenses looks right.

Vision Could Be Improved By Injecting Semiconductor Specks Into Retinas

Vision Could Be Improved By Injecting Semiconductor Specks Into Retinas 


The idea of creating a bionic eye to assist people with seriously impaired vision is definitely exciting. But installing a silicon chip into a human eyeball to assist the retinas has some drawbacks, the least of which being that the chip itself can block light from falling on areas of the retina that are healthy and still working properly. So Jeffrey Olsen at the University of Colorado Hospital has come up with a different approach.
