Cob: Re: Re: living roof

[Wendy Russell]

Could you elaborate on the solar collecting metal roofs? (ie do you have any
drawings or pictures, web site etc??).
Also, based on your years of experience - which type of roof would you
personally go for ? - earthen, metal - or a combination ?
Thanks, Wendy Russell
