New generation nuclear power stations that produce cheap electricity and less waste always seem about to appear, but so far they have not materialised, promises for the last 18 years, by the United States Office of Nuclear Energy (NE) as a way to provide cheap and plentiful supplies of electricity, are unlikely to be fulfilled any time in the next 30 years.
This story publicises Sunlight and Seaweed: An Argument for How to Feed, Power and Clean Up the World by Tim Flannery, published by Text Publishing, describing how large offshore rafts, 1km or so square, buoyed 25m below sea surface, can be used to tether ropes, to create healthy new environments growing plant material, giant kelp, seagrass and others, to support growth of shellfish and fish. Kelp can grow as much as 600mm per day, absorbing at least 10 times more CO2 than rainforest, also reducing acidity in seawater to improve conditions for marine life.

Forests more valuable standing than cleared. US economists have found how to subsidise protecting African forests at the village level.
Economists have just shown that, at least sometimes, money does grow on the trees of African forests. By paying villagers in Uganda quite small sums not to clear the forest on their land, they changed collective behaviour and more than halved the expected tree loss. And they demonstrated that the rewards of preserving forest were in cash terms more than 2.4 times greater than the monetary cost of saving the woodland, according to a new study in the journal Science.
So what will it take to prevent Barnaby Joyce and fellow vandals from resumption of land clearing, back up to 40 footy fields per day?
So simple+effective, even @TurnbullMalcolm + #coal can’t misunderstand

VW new model ID is mass market EV, similar in size to Golf, scheduled for first release in Germany 2018. Expectations are better performance and price than Tesla Model 3 and cheaper, equivalent price of Golf diesel. As with July 2017 Golf, new models always get new electronic whizz bangs, touch screens etc but even new petrol engines will be saved for other markets. Because our standards are so low, Australia is a dumping ground for other car brands low spec engines and low car prices, so market share for VW and others is undermined by cheapness. It will take many of us to hustle our leaders to get with 21st century.

How about this for innovation and entrepreneurship? In Dubai already, cops can safely and comfortably stay driving a desk, while driverless cop cars cover the beat, continuously gathering video, performing face and rego plate recognition. Inevitably, these things aren’t designed for high speed pursuit but each car is teamed with a drone which can track at high speed so intercept can be organised.
Despite data in Finkel report being out of date, with respect to recent big drops in cost of wind and solar, especially large commercial versions, the same with storage, all to not scare the horses of COALition right wing rump, Turnbull has dropped his trousers. Wasn’t major objective to get rid of “uncertainty”? How much will they spend on clean coal before even Phoney Tony has to admit there’s no way it can compete on basic price even before budgeting for any kind of emission offset.
Are gas peaking plants really needed to top up supply when solar or wind or both occasionally dip below demand? Previously, fossil fuel brigade always wanted gas peaker plants close to demand locations but suffered the wrath of NIMBYS every time they tried. The Finkel report encourages storage but fossil fuel bigots interpret that commercial wind and solar need to include storage, at remote site. They insist that power out of coal fired, steam powered plants is always perfect, disregarding that they can get seriously out of synch when big enough transients are felt back at source because they’re too slow to respond. Where dips and surges happen is out on the poles and wires, so doesn’t it make sense to put storage out there, especially with technology fast enough to repair 50Hz power on the fly, so that minor transients don’t become major.
