If you have a particular interest or project in mind, go ahead and start it! If you have questions or suggestions, the best place to leave them is at our community discussion page, which we call the Village pump - you should get a fast response. Or, feel free to leave me a note on my talk page if you have further questions, need help finding your way around, have a cool idea for a project, or just want to chat. If you just want to know how things work here, check out Appropedia:Policies and Appropedia:FAQ. We're a relaxed and friendly bunch though, and you can also just pick things up as you go.
Glad to have you here!
Desalination, and carbon storage with wood[edit source]
Thanks your work. Water Desalinization Using Water/Wind/Solar Power seems like a reasonable start. I don't know a whole lot about these technologies, but I know that desalination tends to be more expensive and energy intensive than other water treatment methods. However, when the only only available water is saline, it may be the best option (rather than trucking or piping water from far away.) However, perhaps a cleverly designed solar still, for example, could turn out to be more affordable and practical than previous designs.
If there is limited freshwater, but also some water with higher-than-desirable salinity, the saline water is sometimes used to top up the freshwater – but a limited amount, so that the final salinity is within acceptable levels. Something to keep in mind.
Carbon Capture and Storage Using Wood also looks like a good start – and on a very important topic.
Thanks a lot for taking the time to look at my pages and tweet them. I really would like input from other people, especially knowledgeable ones. There is only so far I can take these ideas by myself so I greatly appreciate your help and that of the Appropedia community. -- GreenGuy
