Michael Janke grabs a meter and checks the power consumption of a few household electrical items, chiefly those power blocks we're now being told to switch off if we want to save the planet.

One of BB's most-respected research associates has kindly sent a 1930s travel guide to "Aberystwyth and North Wales". We plan to write a whole entry about this shortly (here's a scan of the Aber street map as evidence of our good intentions), but in the meantime we're going to outline, delineate or otherwise circumscribe the parameters of the perfect day out in modern-day Aberystwyth.

Take a gander at this image of Richard Burton and his father in their hometown of Pontrhydfen in South Wales. Burton, the epitome of the local boy made good in pale casuals, strides purposefully along a rough Welsh road trailed by his mining father, a small man dressed in his everyday suit and wearing a battered cap. An absolutely iconic image, taken for a Picture Post feature and never published (although it appeared in B&W Photography magazine a while back, which is where we first saw it). And can you buy a copy for your wall? Can you sod.
