I want to delete my kyoto trough insturctable but it was in a contest so it will not let me. Answered
It was in a contest and it seems you cannot delete stuff that was entered in a contest.
I made the instructable to attract smarter people than me to the problem of unattended concentrated solar cooking by combining 2 reflective troughs (to mimic a dish).
(Troughs are easy to make (bent in one direction). while dishes are bent in 2 planes so they really hard to make without wrinkles on the reflector material. Nobody got attracted so I guess the idea is dead.
Anyway, for me personally, it was a stepping stone on the way to the clam shaped solar reflector.
So it was useful but it is history now.
So is there any way to delete it or substitute another thing in its place?
