Solar furnace melts rock - video

In this clip from BBC One’s “Bang Goes the Theory,” a high-performance solar furnace focuses normal sunshine into a heat-ray that reaches 3,500 deg C, hot enough to melt rocks. Watch it here : Video

  1. Impressive and fun at the same time; not sure if it reminds me more of a Bond villain or my mispent schooldays burning my name into fences with a magnifying glass.

    I wonder how much a low tech, low power version would cost, something just enough to run the central heating and provide hot water. I'd imagine that a fairly tiny unit would be the result of downrating the performance, far easier to fit (and retro fit) than the usual solar hot water panels.
