10:10 Climate Action have published a report on how solar PV can be connected to trains running DC traction using a third rail, as in London, Merseyrail and elsewhere.
Grid capacity constraints mean new renewable generating capacity can no longer connect affordably across whole regions of the UK.
Withdrawal of subsidies for solar PV means only developments with an on-site final customer are now commercially viable. Traction power demand from railways is increasing, and railway operators could be supplied with track-connected solar that is both lower cost and much lower carbon than grid-supplied electricity.

NASA has published a film of Earth’s seasons showing how the climate has changed in the past twenty years. As they say, we only have one planet, and it’s a delicate place.
The data visualization, released this week, shows Earth’s fluctuations as seen from space.
The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance – or lack – of undersea life.
“It’s like watching the Earth breathe. It’s really remarkable,” said Nasa oceanographer Jeremy Werdell, who took part in the project.
India is in the midst of a toilet-building frenzy, the government has set aside $20bn (£15bn) for the health initiative and aims to stop people having to defecate in the open by 2019.
One social enterprise in one of India’s poorest areas is taking on the challenge of building public toilets.
It is using the waste from the toilets to help pay for their upkeep.

Daan Roosegaarde is creating smog-free towers, which concentrate pollution into carbon and generate clean air, and jewellery made from the carbon. You can buy rings from his organization made from polluted air. (The pollution in Chinese cities is equivalent to 17 cigarettes a day.)
Today Rotterdam and China, tomorrow the world!
