This "Asaklitt Spirit Stove" trangia clone seems quite conic (conic pot supported by conic windshield, just like caldera c(l)one) and is quite light compared to a trangia, especially if drop fry pan and one pot. Also cheap 9.99. I never liked the trangias pot supports: the above seems simpler, and more efficient.
I read the trail article in which I hiker used a radical design hiking trailer to carry their gear along the west highland way, allowing a small day sac for day trips up mountains, and no weight on back when walking the trail:
the wheels arent so good on rough ground (bigger wheel(s)would be better), possibly a monowheel (like similar monowalker.com trailer), but I think wheels are only more efficient than legs, when used on a smooth surface (hence the lack of wheeled animals):
so I wondered, given that clever prosthetic legs with some intelligent joint exist, could the wheels in these hiking trailers be replaced with a couple of such 'legs', low battery consumption electronics might control how the limbs bend, but all motive force would be provided by the towing human. Then the advantage of no weight on your back could be extended into the mountains (and Terry Pratchetts "The luggage" would actually exist).
