In 10 years' time trains could be solar powered

Alice Bell for The Guardian:  Last week, my 10:10 colleague Leo Murray co-authored a new report on solar-powered trains with Nathaniel Bottrell, an electrical engineer at Imperial College.

It’s exciting stuff. We think solar could power 20% of the Merseyrail network in Liverpool, as well as 15% of commuter routes in Kent, Sussex and Wessex. There’s scope for solar trams in Edinburgh, Glasgow, Nottingham, London and Manchester too, and there’s no reason it should just be a British thing either. We’re especially excited about possibilities in San Francisco, Mexico City, India and Spain, but trains and trams all over the world could be running on sun in a few years time.

It’s also a genuine world first. There are a few solar stations – Blackfriars Bridge being by far the coolest – and some trains in India even have solar panels on their roofs, but that’s just to power equipment like lights and fans. No one’s moving the trains themselves with solar. Yet.

What’s especially interesting is how our new innovation came about – in particular the role community energy groups have played in its development (often despite policy support, not because of it, or in response to policy constraints). Looking ahead, there are also important questions to be asked about what role these community groups might play in its deployment.

The idea came from a community solar group in Balcombe, West Sussex, formed in response to the first anti-fracking protests in the UK, in the summer of 2013. After the drillers, the activists, the press and various other hangers-on had left, the villagers were left with a question our current energy system lets most of us ignore: how should we power ourselves?  Full Article:

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
