Interesting recent post from the World Economic Forum . At a global level solar energy supply will surpass nuclear energy by the end of the year in terms of generating capability in Gigawatts.

Still a lot to be done to make these commercially viable, but we keep edging closer. Passenger trials are set to start in 2018. It is pleasing to see that fuel cell technology has not been abandoned, and with design development and “lean” thinking the trains will become even more effective /efficient.

Scorched Earth

The term “Scorched Earth” has been used widely as a military term for removing potentially useful things away from a withdrawing or advancing enemy in the field of battle. However, I would also like to use this as a metaphor for just destroying anything rapidly, without a great deal of thought.
