Water box grows trees in desert

This water-box extracts dew from the night time air and siphons it down underground where it will slowly release it to plants. They’ve used it in Dubai to help saplings grow where there is 50C days, sand storms, and camels! … Continue reading

Naomi Klein makes me angry, again!

First of all, she’s anti-nuclear. Enough said. But today is about the oceans. Geo-engineering, or sequestering CO2 by tipping iron dust into the ocean, is bad as well, according to Klein. She doesn’t spell out why it is bad: the … Continue reading

The Science Show (Oct 2011) reports on a new blimp hose test that will measure some of the engineering challenges involved in this method of deploying the sulphur gun. We’ll have to pay attention to this in coming months as … Continue reading

Forests in Aussie outback and Sahara = solve global warming!

These guys have modelled it and it works! Each year, irrigated Saharan- and Australian-desert forests could sequester amounts of atmospheric CO2 at least equal to that from burning fossil fuels. Without any rain, to capture CO2 produced from gasoline requires … Continue reading
