In June 2013 we visited Russia. Before that we had a couple of weeks in the UK while our frequent travel companions Craig and Sonia, together with Sonia's two Russian speaking cousins and their partners and two other couples, travelled from Beijing by the trans-Siberian railway. We all met up in Moscow and a day later joined our cruise ship. The tour provided another three guided days in Moscow before setting off for a cruise along the Volga-Baltic Waterway to St Petersburg; through some 19 locks and across some very impressive lakes.
We children were almost overcome with excitement. There had been months of preparation. Tree lopping and hedge trimmings had been saved; old newspapers and magazines stacked into fruit boxes; a couple of old tyres had been kept; and the long dangerously spiky lower fronds from the palm trees were neatly stacked; all in preparation.
Since I first published an article on this subject I've been taken to task by a young family member for being too negative about the prospects of a Hydrogen Economy, mainly because I failed to mention 'clean green hydrogen' generated from surplus electricity, employing electrolysis.
Back in 1874 Jules Verne had a similar vision but failed to identify the source of the energy, 'doubtless electricity', required to disassociate the hydrogen and oxygen.
Coal; oil and gas; peat; wood; bagasse; wind; waves; solar radiation; uranium; and so on; are sources of energy. But electricity is not.
Electricity (and hydrogen derived from it) is simply a means of transporting and utilising energy - see How does electricity work? on this website.
