Kirknewton level crossing needs a pedestrian crossing!

A recent post by the Met Office caught my eye. 40% of UK citizens caught out by severe weather Kirknewton's "new" level crossing , installed in 2013, makes it impossible for pedestrians to cross the line when the crossing is down.  Most evening commuters arrive on the Westbound platform from Edinburgh, often to get to their cars parked in the station car park on the north side of the crossing.  If the crossing has failed - a frequent occurrence - such commuters may eventually seek an alternative route .  In bad conditions that could be 3km through the snow. After departing the village via the underpass, commuters would be navigating an unlit farm lane, probably by now buried under several feet of snow.  Kirknewton needs a permanent pedestrian crossing at the level crossing!

UK democracy is broken - what next?

I think our democracy is broken. Not broken enough for this: China cuts children's online gaming to one hour Or this: Taliban kills Afghan folk singer in restive province ... but is it really so far from shrugging your shoulders at a system which ignores nearly 60% of voters and the terrible things that followed from 1930s Germany, Serbia, the millions who died in Stalin's prison camps and so many other times in history when people turned their backs?

Trust my bank login details to a third party?

The UK has open-banking legislation which allows regulated companies to ask you for authorisation to login to your bank accounts. They can then offer you services like analysing your spending to recommend ways to save money. Note that these sites are regulated but you should not take my word for it. Please get their registration details and input them at the UK FCA site to confirm for yourself they are still currently legal to conduct this type of business in the UK. Snoop You'd think the name would put some people off. Snoop does what it says. Has a look into your every transaction, summarising them by what it knows about the payments and, for example, suggests an energy provider with a better deal. I like the fact that Snoop summarises spending, in away the normal bank statement just does not help with. However Snoop also displays things like how much I spent with a particular ISP since Spring 2019. I'm not sure what the relevance of those multi-year summaries are, except to...

 The COVID-19 pandemic has far from gone away , Storm Francis rages and we await the potential arrival of whatever's left of the unprecedented two hurricanes affecting the Gulf of Mexico. 

In the unlikely event it works...

This could change the world, big time. https://newatlas.com/aircraft/reaction-e ngines-ammonia-carbon-free-aviation-fuel/ Alan Bond, Chief Designer at Reaction Engines Ltd has a history. He was involved in the'90s with an attempt together with Rolls Royce Aeroengines, to build a hypersonic vehicle called Hotol . With scramjet engines, it would only carry oxygen to power flight out of the atmosphere. More recently, Reaction Engines Ltd, with some funding from the UK government, had the European Space Agency certify their plans to use a supercooler to lower the intake temperature and velocity. It's unlikely this proposal will be any more successful, convincing the British Government, historically dominated by upper-class classics and arts graduates, that a technical idea could really change the world has always proved impossible in the past.

Mars now? Why?

It was an amazing achievement but Mars is probably a bridge too far. We should extend out into space, but with small steps. The ISS, a permanent moon base, asteroid mining. Each building more infrastructure, more habitable spaces to go. Hundreds of years ago many sailors died on a world with a breathable atmosphere, mostly liveable temperatures, water - not always fresh. It took centuries for systems to evolve that improved navigation & propulsion enough that most sea voyages did not result in the deaths of the voyagers. And that was of course on our home planet. One NASA engineer was quoted as saying there were still 57 total loss mission-failure scenarios they did not know how to solve a couple of years ago. Mars contains nothing of special appeal apart from the explorer thrill of standing on another world. It's a very cold, hostile place with no breathable atmosphere and no accessible resources to sustain a long landing and return. The nine-month each way journey gives no pr...

So wind is the answer?

UK generation Look at any day, week or month. See the red line? That's gas turbines.  Burning gas is better than coal for soot, but carbon is carbon. Methane plus oxygen generates heat plus carbon dioxide. https://www.ucsusa.org/resources/environmental-impacts-natural-gas The blue line, that's wind. There's about 14GW of total capacity in the UK at the moment. That's about half the UK's average demand.  https://www.gridwatch.templar.co.uk/ Except on Tuesday, when it was almost zero. So it is on any hour, day, week or month you look at.  Electricity demand varies a bit, but the red line is almost a mirror image of the blue. That's because electricity can't be stored in any great quantity. The pumped storage and batteries on the grid at the moment are used only for smoothing, not covering major gaps in the wind.  Every time the wind turbines stop, the gas turbines start In a BBC News report yesterday, the 9th of June 2020, a screen showed a picture of coal gen...
