Building a Telegraph in the Wilderness

Jamie O’Shea decided to try to build a telegraph using nothing but stone-age tools. He uses nothing modern, except information. He is wearing a suit, though I suspect that is for dramatic effect — collapse of civilization and all that. Or he may just have a day job.

He writes:

Some people have viewed this project through the lens of sustainability. While self-sufficiency and locally sourced material would certainly seem to be sustainable, my methods fail quite spectacularly in environmental analysis. For one, I used an estimated 20 kg of charcoal to produce perhaps 20 g of metal. Much of this was wasted in the learning curve, but it was used just the same.

I had zero emissions control. While roasting my copper ores, I directly vented all the gases being produced. The noxious sulphur dioxide, chief precursor to acid rain,  gagged me when I got too close. Moreover, I got sick twice after this phase of the process. At first I assumed this was from the sulphur, but after further reading, my symptoms more closely resembled mild arsenic poisoning. Arsenic is a heavy metal usually found in ores of copper that sublimates away during the roasting process. So I have to issue a “don’t try this at home” warning. The only way I can see this process being described as sustainable is that I was distracted from more effective activities of consumption for 6 weeks. But this is easily canceled out by the 3 round-trip cross-continental voyages taken to complete the project.

  1. @ K Scharf: From a pragmatic standpoint, you forgot the most important part — who’s he going to talk to? Telegraphs from any era only work if there are two of them.

    But I believe this experiment is not about pragmatism, so much as it’s a a proof-of-concept exercise. And an interesting one, at that.
