On November 17 we had the third workshop about The influences of medicinal plants in Permaculture. The objective of this theme was to introduce the importance of medicinal plants within permaculture environment. For this workshop we had the support of the trainer Simon Leja Bixcul.

Arrays of tree-like nanowires consisting of Si trunks and TiO2 branches facilitate solar water-splitting in a fully integrated artificial photosynthesis system - Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have developed the first fully integrated nanosystem for artificial photosynthesis, in which solar energy is directly converted into chemical fuels. “Similar to the chloroplasts in green plants that carry out photosynthesis, our artificial photosynthetic system is composed of two semiconductor light absorbers, an interfacial layer for charge transport, and spatially separated co-catalysts,” says Peidong Yang, a chemist with Berkeley Lab’s Materials Sciences Division, who led this research. “To facilitate solar water- splitting in our system, we synthesized tree-like nanowire heterostructures, consisting of silicon trunks and titanium oxide branches. Visually, arrays of these nanostructures very much resemble an artificial forest. “In natural photosynthesis, the energy of absorbed sunlight produces energized charge-carriers that execute chemical reactions in separate regions of the chloroplast,” Yang says. “We’ve integrated our nanowire nanoscale heterostructure into a functional system that mimics the integration in chloroplasts and provides a conceptual blueprint for better solar-to-fuel conversion efficiencies in the future.” Via Wildcat2030 Delete the scoop?

High-speed rail is still just a dream in America. But why then aren't smart roads a reality?
It is possible to imagine a world in which smart pavement, smart cars, and embedded monitoring and controls would turn highways from gulches that pollute a wide swath of land around them with both particles and noise would become more like rivers.

Mark Vander Meer gives a presentation on soil science as it relates to forestry. I was presenting in another room at the same time, so Mark gave permission to Jocelyn Campbell to record this for me. Once I saw it, I thought it was so good, that I asked Mark if it was okay to put it up on YouTube. Delete the scoop?

This is where I want to return to the idea that what we face is a design problem, where answers exist not at an unattainable theoretical level but on the floors of our factories, in the streets of our towns and cities, the classes of our schools, the waiting rooms of our hospitals. These answers will manifest themselves as true acts of creation, originating new ways of getting stuff done, informed by the decisions we collectively take. So in re-designing the world, we need human creativity in the sense of the capacity to ‘make’, we need visionary leadership in the sense of making a difference. And we seek the craftsman’s critical eye, steady hand and creative mind. It is this process of seeing – realising new pathways to success, by bringing two ‘unlikes’ (new information, tools, processes etc.) together in close adjacency – that we create, and make new things. Then we can meaningfully apply that capability. Delete the scoop?

A bit of background: "conservation banking" refers to banking for listed species under the ESA (a backgrounder is available here), whereas habitat credit trading (HCT) refers broadly to voluntary offsetting that seeks to protect imperiled species and habitat. HCT has been in the news a lot recently thanks to interest in incentive mechanisms to protect so-called 'Candidate Species', which may be eligible for listing under the Endangered Species Act but the listing hasn't happened yet.
