South African entrepreneurs are taking climate change seriously: Water filters made from macadamia nut shells, a mobile solar-powered kiosk for charging phones in off-grid areas, vegetable growing systems using recycled plastic bags, and a machine that turns any type of waste into energy (gas) or diesel.

We find ourselves at the foundations of a new reality, a New … [Read more...]

Employing aliens to capture carbon
Imagine turning thirsty alien invasive trees into biochar. Biochar is charcoal created by pyrolysis of biomass.

Let the sun do your braai!
The Sun: it rises each day unpaid and taken for granted. Few places in the world are as blessed with such richness of Sunlight as Southern Africa, and to say that South Africans like to Braai is a colossal understatement.

Free energy from your own waste – biodigesters make sense
In the pursuit of a greener, healthier lifestyle we are constantly on the lookout for new ways to turn our wasteful lives into a more logical nature-simulating exercise, as Nature is always our best teacher.
