Elon Musk has been in the spotlight a number of times on my blog now, and once again he succeeded in creating a good portion of buzz in the cleantech world which I cannot let go unnoticed. Yesterday the Silicon Valley entrepreneur announced that Tesla is now taking online orders worldwide for their latest disruptive technology: the solar roof. Seen by Elon as the third leg of the stool of a sustainable energy future, next to Tesla’s Powerwall and electric car, first installations in the US follow later this year, while worldwide rollout begins in 2018.

CloudFisher turns fog into drinking water

Last Wednesday the 22nd of March, the UN celebrated the World Water day. Many take drinking water for granted, but there are still 1.8 billion people in the world who use a source of drinking water that puts them at risk of getting deadly sick. In the driest and poorest regions of the world, women and girls walk for hours in the blistering heat to collect water for their families –withholding them from studying or working. Addressing the drinking water crisis of those regions can solve many problems at once.

Turning waste milk into loo paper

Carezza di latte, caress of milk. It sounds like a new version of delicious Italian coffee to me, but make no mistake. It is the Italian toilet paper brand Tenderly’s latest premium product. Silky soft, it holds the promise of a supreme caress even for the most sensitive skin. And all of that with the help of waste milk. Sounds amazing, don’t you think?

Turning CO2 into ethanol: is this the new hydrogen?

Last week my facebook feed nearly overflew with shares of an amazing discovery: a group of US scientists of the Oak Ridge National Laboratory in Tenessee had accidently stumbled upon a catalyst that turns CO2 into ethanol. For those of you unfamiliar with catalysts, they are materials or substances that speed up or slow down the rate of a chemical reaction by providing a ‘reactive site’. The catalyst itself is not altered during the process (don’t run away, the article won’t get more complicated than this ;) ).

Well well, I thought. It’s about the fourth or fifth time this year I read about a new technique to suck CO2 out of the air. This one sparked my interest more than previous discoveries, though. (more…)

If you are a traditional farmer, you’ll need water and energy to grow your produce. And you’ll need lots of it. The challenge is that they are finite resources that are becoming ever scarcer. Our solution? Not to use them!

Sundrop’s website bulges of this kind of statements. It is clear that the South Australia-based farm is pretty proud of their achievements over the last six years. In cooperation with an international team of scientists, they developed a commercial farm that runs on solar power and seawater. Yes, you read that right: they are producing tomatoes with just salt water from the nearby Spencer Gulf and the energy captured by a solar power plant.
