Products that do what Helios – what plug-in solar could generate for any address in Britain does

Plug-in solar panels (no electrician needed) have just become legal in the UK and will go on sale soon. Helios estimates how much electricity a typical installation could generate at a given address and what that's worth against your tariff. It uses UK government LIDAR data to reflect the actual skyline, so it knows whether there's a building or a hill blocking the sun. Caveats: - Outside LIDAR coverage (most of Scotland and Wales) it falls back to a synthetic horizon (less accurate). - Trees and recent developments (post-2022 or so) may not be in the data, and some address placements could…

    GB Renewables Map an energy experiment created entirely in my free time (day job is visualisation at Octopus Energy). It's an interactive map showing live generation for major wind farms in Great Britain, showing what each wind farm is generating both now and in the past, and where that generation is physically located. Animated weather data is from WeatherLayers and shows current and historic wind conditions on the map, providing context to wind generation around the country. History mode allows you to go back in time and see wind generation and weather conditions for a particular date and…

    Hi HN! I quit my job two years ago to have more time to work on my side projects. The main one is an automated solar concentrator. I've just open-sourced it, it's not perfect nor finished, and I still have a lot of ideas for further development, but I'm interested in knowing what you think of it. There are many applications where concentrated solar power could be a viable environmental and economic solution, I hope this technology will one day be more widely used. Feel free to give any feedback and ask questions.

    Last weekend, I tried creating an original visualization of something on many minds in my home country the Netherlands: land use. Much of our discussion revolves around land use—housing crisis, sustainable farming, solar energy—it's all about the land. To illustrate this, I created a map where each hexagon represents 0.06% (26,647 hectares) of land in the Netherlands. The color indicates the type of land use.
