Recently while checking out a new project, I came across a forgotten relic in an unused corner of a building. The structure has had many uses over the decades and somewhere during the passage of time, an old hanging oil lamp was converted to electricity. Rather than dispose of the old 'technology' despite its dated appearance and missing parts the light fixture was re-purposed. Will it survive another 150 years; only time will tell! But what will happen to the light fixtures we install today in 150 years, let alone tv cabling and wiring. I can attest to personally removing about a mile of exposed telephone wires from my current apartment!
