  • Autonomous Vehicle Challenge

    Two driverless and solar power vans have departed from Italy on their way to China via the silk road. During the 13,000 kM trip the vans will drive themselves on standard roads. The hope is that this will help to prove the viability of using current technology to enable autonomous vehicles on public roads.

  • LSF or LSZH Cable

    I've noticed that sometimes there is confusion between LSF and LSZH cable sheaths and what the differences are. In essence the difference is that both give lower smoke and fumes compared to PVC and in addition LSZH emits no halogens. I have started a Wiki page going into a little more detail at:

  • E-Ink

    Before the technical, some general information. E-ink display are found in a lot of e-readers, some mobile phones and similar devices and the intent is to provide a reading experience closer to that of ink on paper than conventional LCD displays deliver. E-ink screens are not backlit and require light falling on them in the same was as reading a book does; reducing eye strain during long reading sessions. An e-ink page is also persistent (does not need power to maintain the text) and power is only required for changing text on the page. The persistent nature of the pages leads to longer times between charging.

  • Maximum Demand for Buildings

    Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building in my experience a very subjective . Allowing too much power results in additional equipment, increased space requirements, greater system losses and extra cost. On the other side, no enough power results in operational problems. Trying to find the right amount of power is like gazing into a crystal ball and everyone will see something different.

  • Paternoster Lifts

    These lifts were first built in 1884 by J. E. Hall and called a paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) due to its resemblance of a loop of rosary beads. The are not built anymore, apparently due to safety concerns (have to say I was always slightly worried about somehow becoming squashed).
