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.

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[…]

Or a conveyor belt system You can get commercial systems: And there is a couple of Arduino versions Read more about Seed sowing robot[…]
i Been pondering the sustainability of Aluminum mulches recently. You can buy disposable mulch, but that doesn’t seem very sustainable. It’s an idea that’s been around since the 1950s and some have reported increased yield and even reduced pests What if you used 2mm thick stuff that could have regularly placed holes cut? It would Read more about Aluminium sheet mulch[…]
