  1. Let us know who you use for the kit if you go that way
  2. There is another about pumping water to lift a weight, similar to Gravitricity but using water. Flow batteries seem good too but I need to do more research. They should use materials that are abundant, I see Vanadium costs are now through the roof.
  3. Thanks, I'm just interested as Lithium Ion seem to be limited when there are so many other viable solutions
  4. Has anyone experience of flow batteries and specifically vanadium redox flow batteries. Just after any experiences or information. What do we think will happen with Vanadium prices as they have risen recently. Perhaps Zinc Bromide flow batteries would be better as zinc is relatively abundant. Just curious!

    Blown cellulose is used widely in America in timber framed buildings. I must do some more research

    You could Larsen Truss and blow in cellulose, its fire rated??
  7. Another advocate of Sketchup here
  8. If you do find it, let me know as I've recently moved house and want to set up some sensors to monitor temperature, humidity and general air quality
  9. Everything with EnOcean is a struggle. For such an innovative company they don't have the greatest sales personnel. I speak from commercial experience
  10. It's a bit more complicated than that. We'd need more info on your build and what you want?
  11. I specify plenty on commercial projects that are linked to access control systems. Not that make but im sure if you do the usual checks and look into what the security is around coding of swipes it should be ok.
