Talking Topics is a list of issues that come up on the web or in books, the latest of which we will discuss at our meeting on the date given.
Here is an example of creative thought in battery technology. I expect many thousands more of such new technologies to help us stop emitting CO2.
Lithium-ion batteries with ever-increasing energy densities are needed for batteries for advanced devices and all-electric vehicles. Silicon has been highlighted as a promising anode material because of its superior specific capacity. During repeated charge-discharge cycles, silicon undergoes huge volume changes. This limits cycle life via particle pulverization and an unstable electrode-electrolyte interface, especially when the particle sizes are in the micrometer range. We show that the incorporation of 5 weight % polyrotaxane to conventional polyacrylic acid binder imparts extraordinary elasticity to the polymer network originating from the ring sliding motion of polyrotaxane. This binder combination keeps even pulverized silicon particles coalesced without disintegration, enabling stable cycle life for silicon microparticle anodes at commercial-level areal capacities.
The email in my inbox last week offered thirty suggestions to green my office space: use reusable pens, redecorate with light colours, stop using the elevator.
Back at home, done huffing stairs, I could get on with other options: change my lightbulbs, buy local veggies, purchase eco-appliances, put a solar panel on my roof.
And a study released on Thursday claimed it had figured out the single best way to fight climate change: I could swear off ever having a child.
These pervasive exhortations to individual action — in corporate ads, school textbooks, and the campaigns of mainstream environmental groups, especially in the west — seem as natural as the air we breath. But we could hardly be worse-served.
While we busy ourselves greening our personal lives, fossil fuel corporations are rendering these efforts irrelevant. The breakdown of carbon emissions since 1988? A hundred companies alone are responsible for an astonishing 71 percent. You tinker with those pens or that panel; they go on torching the planet.
“The UK’s first geothermal plant could come online as soon as 2020 – research suggests the technology could one day generate a fifth of the nation’s power”

This is climate insensitivity –
This is climate sense –
Whatever the climate deniers are doing & saying, the change over to renewables is happening anyway.
A growing number of states are requiring large batteries to be used to store electricity to help expand wind and solar power. The trend is catching on quickly as at least three states have created energy storage targets or incentives so far this year.
Lawmakers in New York passed a bill last week requiring the state to create an energy storage target. Nevada passed a bill incentivizing energy storage in May, and Maryland passed an energy storage tax credit in April. Those measures follow California, Oregon, and Massachusetts, which have mandates for electricity storage in batteries.
Let’s have international competition on climate enhancement. Just like the space race there will be lot’s of technological spin-offs that will help our world.

And, after the bonfire of all those regulations that bind us in read tape:
Do you remember 8th March 2014, that’s when Malaysia Airlines flight MH370 disappeared. That’s a mere three years ago. That’s the timescale on which we have make a real change on CO2 emissions.
While the greenhouse gases poured into the atmosphere over the last two centuries have only gradually taken effect, future changes are likely to be faster, scientists fear. Johan Rockström of the Stockholm Resilience Centre said: “We have been blessed by a remarkably resilient planet over the past 100 years, able to absorb most of our climate abuse. Now we have reached the end of this era, and need to bend the global curve of emissions immediately, to avoid unmanageable outcomes for our modern world.”
And, many other people who though this project ridiculous.
Generations of British consumers have been locked into a “risky and expensive” project by the UK’s subsidy deal for a new nuclear power station at Hinkley Point in Somerset, according to a damning report by the spending watchdog.
Need I say more?
But we still have to move faster.
Lins said the switch to green energy needed to speed up and, crucially, start converting transport, heating and cooling to renewable sources. “The world is in a race against time,” she said.
Christiana Figueres, the former UN climate chief who delivered the Paris agreement and is now convenor of Mission 2020, said: “The economic case for renewables as the backbone of our global energy system is increasingly clear and proven. Offering ever greater bang-for-buck, renewables are quite simply the cheapest way to generate energy in an ever-growing number of countries.”
