Lithium-ion batteries and other electricity storage news

New Scientist looks at the state of play in battery storage (paywalled)

The momentum at present is with lithium-iron batteries, which are being used in devices from mobile phones to electric cars. Since the technology was commercialised in 1991 its performance has improved immensely – design tweaks have tripled the energy stored in a given volume.

1. FactCheck: Would Labor’s renewable energy plan cost consumers $60 billion?

The verdict:

Coal renaissance, as scientists meet and the faithful examine their conscience

French President Francois Hollande did not turn up to give the opening address at a major climate science conference in Paris recently, being otherwise occupied with questions concerning Grexit. Had he been there he may have been able to explain why France has restored subsidies to the French companies building coal-fired power stations in other countries.

As the matter stands, we are told, a coal renaissance is underway which will deliver a 4°C world, or warmer. Continue reading Coal renaissance, as scientists meet and the faithful examine their conscience

Politics after Bronnie and the ALP conference

The Roy Morgan poll, taken over the past two weekends, headlines:

    L-NP support slumps amid Bronwyn Bishop travel expense ‘misconduct’ and as the ALP commits to renewable energy & ‘turn back the boats’ policy.

Support for the LNP is down 3 points to give Labor a lead TPP of 54-46. The Greens support is at 15% (up 1.5%) – the highest Greens vote since September 2010. Continue reading Politics after Bronnie and the ALP conference

1. Hansen’s alarming new sea level rise scenario

James Hansen has a 17 author paper out suggesting that we could have multi-metre sea level rise this century. It’s based on the notion that meltwater from the ice sheets interrupts ocean circulation patterns, which then cause a feedback loop via larger storms. I think that’s it in brief.

Turning back boats – only by agreement

Turning back asylum seeker boats can only be done legally and ethically, in my view, with the agreement of transitional countries, such as Indonesia, Malaysia and Thailand. Unfortunately the form of the decision made at the ALP conference makes clear that the ALP would seek to act without such agreement. Continue reading Turning back boats – only by agreement

1. Leaders summit

On Wednesday, prior to COAG on Thursday, our political leaders held a summit or retreat to dicuss taxation and the future of the federation. By all accounts they enjoyed the talkfest – Jay Weatherall said it was “very positive” and that “in my sense and my operation in COAG over the last five years, this is probably the most constructive I have ever seen”.

Despite that there is no evidence they actually decided anything except lowering the threshold at which the GST applies to offshore online purchases. Continue reading Saturday salon 25/7

Pathologising unemployment

It can’t be true. In the UK unemployment is being redefined as a psychological disorder as part of an effort to cut the welfare bill by $12 billion. And, says an article in the New Scientist (can’t find the link), the UK

    joins nations such as Australia and the US in increasingly requiring claimants to comply with interventions intended to modify emotions, beliefs and personality.

They say “claimants must demonstrate characteristics deemed desirable in workplaces, like confidence and enthusiasm, in return for welfare.” Continue reading Pathologising unemployment
