The World Economic Forum Talk About Gravitricity

This article on the World Economic Forum is entitled How Gravity Batteries Will Help Us Switch To Renewable Energy.

The article is a must-read and Gravitricity must be very pleased with the contents and placement of the article.

As an investor in Gravitricity, through crowd-funding, I am certainly pleased.

Hydrogen Fuel Cells Could Get A Lot Cheaper With Newly Developed Iron Catalyst

The title of this post, is the same ass that of this article on Hydrogen Fuel News.

These are the first two paragraphs.

Scientists have been looking for an alternative to precious metals such as platinum for decades, in the hopes of bringing down the cost of hydrogen fuel cells.

An alternative to a platinum catalyst that costs considerably less will help to bring down the cost of hydrogen fuel cells and of using H2 as a carbon emission-free fuel. This would make it cheaper to both produce and use H2.

Researchers at the University of Buffalo, appear to be on the road to using iron as an affordable catalyst.

This paragraph describes he structure of the catalyst.

The researchers looked to iron because of its low cost and abundance. On its own, iron does not perform as well as platinum as a catalyst, particularly because it isn’t as durable in the face of highly corrosive and oxidative environments such as those within hydrogen fuel cells. The researchers bonded four nitrogen atoms to the iron in order to overcome that barrier, followed by embedding the material within a few graphene layers “with accurate atomic control of local geometric and chemical structures,” said Wu.

Gang Wu is leading the research.

In the early 1970s, I worked with one of ICI’s catalyst experts and he said, that improvements in this area will be large in the future.

Increasingly, I see his prediction being proved right, in the varied fields, where catalysts are used.

Network Rail Uses Tree Planting Initiative To Combat Graffiti Hotspot

The title of this post, is the same as that of this article on Rail Technology Magazine.

These two paragraphs introduce the article.

Network Rail has planted 35 trees, as part of its many sustainability initiatives, at a graffiti hotspot location in London with the hopes of acting as a vandalising deterrent whilst also improving the natural habitats within the area.

This action marks the first time that Network Rail have used ecological measures such as these to prevent graffiti and vandalism. The tree planting at the Bermondsey Dive Under – a junction where one set of rail lines tunnel under another – will not only create nicer visual stimulants for passengers and local residents but will also contribute to significant cleaning cost savings. It is estimated that the graffiti at the South-East London hotspot has cost taxpayers £150,000 in cleaning and rejuvenation works over the last 2 years.

I would expect that £150,000 buys a lot more than 35 trees.

These pictures show the trees from a train going Between East Croydon and London Bridge stations.

I also wonder whether those that are caught for painting the graffiti, should be sentenced to a community service order to plant new trees to stop the vandalism.
