I’ve written before about #liquidsolar What might the rest of the renewable energy system look like? Electric cars with Vehicle to grid could buffer some renewables. Open Source electric cars may change patterns of consumption of new vehicles bringing in ‘mobility as a service’ Hydrogen might also play a part in converting the rail Read more about Renewable Energy[…]
So it seems that there are a couple of challenges with a completely renewable energy grid in a Northern European context. 1) We don’t have that much solar energy 2) The solar energy we do have is rarely at the right times So if we don’t have enough energy we probably need to import some.

Containing a 32Gb library of carefully curated educational content and apps to enable access to education and health information. The information is accessed through the Kiwix reader. Marketed through existing solar PAYG networks to people who Read more about Rosetta Phone[…]
When he squints, he can see, maybe 30 years down the road, Africa’s coast dotted with supertankers, docked at offshore rigs. But they wouldn’t be filling up with oil. Seafloor powerlines would carry renewable electricity to the rigs from wind and solar farms on shore. On board, one device would use the electricity to desalinate Read more about Liquid solar energy[…]
Disclaimer – this is just some notes to help organise my thoughts. It might be of interest to someone, but it’s not a ‘proper’ blog entry. I’m particularly interested in a peer-to-peer mesh as a network for SSB messages: a decent(ralised) secure gossip platform https://www.manyver.se https://github.com/staltz/manyverse https://www.scuttlebutt.nz https://github.com/ssbc https://github.com/ssbc/stack-diagram It works, with a sufficient density of Read more about Offline communications in 2018[…]
The thousand trees project – Fuel and carbon capture. Distributing a forest in the urban landscape of Bristol UK, then using the coppiced wood to create heat, power and biochar to capture and store carbon. This is essentially reverse coal mining, taking carbon from the atmosphere and storing it in the ground. Agroecology Lab is Read more about The Thousand Trees Project[…]
Last year I brought a Edyn smart garden thing. It was closed source, but solar and shiny. It had a pretty web interface. Then the company went bankrupt Sorry I’ve been informed they are not bankrupt. They’ve just taken their API, and website offline and ceased responding in a timely way to customer service enquires. So Read more about Edyn[…]

Humanity faces the challenge of how to achieve a high quality of life for over 7 billion people without destabilizing critical planetary processes. Physical needs such as nutrition, sanitation, access to electricity and the elimination of extreme poverty could likely be met for all people without transgressing planetary boundaries. More Ecological Footprinting analysis shows Read more about A good life for all within planetary boundaries #OnePlanet[…]
Been thinking about what it is that makes robot harvesting difficult. Part of the problem is picking up the cut leaves. By growing vertically that harvesting could be easier, using a relatively cheap robot arm with scissors and a bucket (above from Micropede) You’d need to move the arm around, possibly using Tslot as rails Read more about Robotic harvesting for Vertical Aquaponics[…]
