It's not me making this claim, go read the article.

Why whale poo could be the secret to reversing the effects of climate change

We do indeed have a fantastic biosphere that steadily reduces the level of CO2 during the natural interglacial periods.

... If that is we give it a chance.


I hope Sea Shepherd can still keep those nasty corrupt Japanese off their harpoons!

Have always loved cetaceans! :) Now I love their poo too :)

Anyone know how to rig up harpoon guns so that they backfire? :)

Here are two high powered contrasting mitigations:


F1? No, it's Formula E as electric racing cars hit the track

Electric motorsport is finally getting some of the attention given its internal combustion engine brother with the first day of testing of the new Formula E taking place at Donington Park Racing Circuit in Derby...

... The first race of the 10-race season takes place in Beijing in September with another in Monaco in May. The cars use a McLaren-built 200kW electric motor with a race mode of 133kW and 67kW push to pass. The cars weigh a minimum of 800kg, of which 200kg is the batteries from Williams. This translates to a 0-60mph (0-97kmph) time of three seconds. The top speed is limited to 225kmph (140mph)...



Dubai to get HUGE climate-controlled DOMED CITY and giga-mall

The ruler of Dubai has announced that the Gulf state is soon to build the world's first climate-controlled city, which will feature the largest area yet contained under a single transparent dome...



The fossils motorised F1 racing motorsport has recently moved to V6 engines with tech that can be used to make everyday road vehicles more efficient. Bernie Ecclestone, the man controlling F1 complained the cars were now "too quiet"...

So it's very interesting the electric "F1" cars are now racing. Are they a splinter group?... More of an efficient whoosh rather than a raucous dirty roar? Regardless, customizing those is going to very quickly drive some new good tech for going all electric.


Meanwhile, already the Arab lands are having to move into off-world Science Fiction conditions here on our own planet earth...

Wind power marches onwards:


Moray Firth subsea cable approved

A planned subsea electricity cable connecting two sides of the Moray Firth has been given approved by the industry regulator.

The 100-mile underground and subsea line, between Caithness and Moray, could add 1.2 gigawatts of new renewable energy capacity to the grid...



That is quite an interesting turn-around... It used to be that we built power lines to where the coalfields were. Now we're building power lines to where the wind blows and the tides flow.

Is one of the solutions to directly engage head-on the Dirty Fossils pollution in the war of Marketing?


For one current example:

Spread the word: tell LEGO to dump Shell

... video ... sent ... earlier this week, which called on LEGO to break its partnership with Shell? I just learned this morning that Youtube has taken it down...

There are hundreds of other LEGO Movie spoof videos online which haven’t been taken down… are they trying to silence us?...




Is this all a game of how the minds of children are polluted aswel as how some parts of our industry are polluting our planet?...

Here is a very good question as to whether nuclear (fission) can ever compete against the very quickly improving gamut of renewable power:


EDF nuclear deal is a bad economic bet

Rising renewables output makes promise to buy Hinkley Point electricity at twice its current price a costly gamble...

... Renewable capacity, mainly solar and onshore wind, is now over 290 gigawatts in Europe. This is an increase of some 85GW since 2009 and equivalent to the capacity of 300 of Europe’s nuclear power stations.

This is an average of about 21GW of new capacity a year. Even if you divide that by a third to allow for the variable output of renewables, you are still adding 7GW of dispatchable electricity a year. This compares rather well with the decade or more it would take to generate that much power from new nuclear power stations in Britain.

These numbers not only make nuclear a very bad economic bet they also make it too slow to make a useful contribution to reducing carbon emissions. A combination of energy efficiency and renewables will reduce carbon pollution faster and more cheaply. If this were not bad enough news for Britain there is more to come...

So, the Big Man of Lego has issued a statement that to my reading indicates uncaring arrogance and that Shell have bought Lego off for the sake of Branding and advertising to children:


Comment on Greenpeace campaign using the LEGO® brand

Jørgen Vig Knudstorp, CEO of the LEGO Group, comments on the Greenpeace campaign using the LEGO® brand to target Shell

...We expect that Shell lives up to their responsibilities wherever they operate and take appropriate action to any potential claims should this not be the case. I would like to clarify that we intend to live up to the long term contract with Shell, which we entered into in 2011...

...deliver creative and inspiring LEGO play experiences to children all over the world...



Greenpeace are following through with their campaign and are working their way around the various head offices for Lego around the world.

Can we shout loud enough to deter the reckless pollution of the Arctic and also the Corporate Branding brainwashing of children?...

Yet another step towards using better cleaner tech:


BEST BATTERY EVER: All lithium, all the time, plus a dash of carbon nano-stuff

Battery capacity remains a big issue in devices ranging from phones to electric vehicles – and one of the biggest constraints is the materials used to make electrodes.

A paper published at Nature Nanotechnology (abstract here), offers a promising lead for improvements as boffins say they've hit on a way to replace today's anode materials with lithium...

... the nanosphere layer is 20 nanometres thick and forms a honeycomb-like protective surface over the unstable lithium anode.

The carbon is chemically stable, so it doesn't react with the electrolyte, and it's flexible enough to expand and contract during the battery's charge cycle. By providing a protective layer, contact between the anode and electrolyte (which causes heat and sometimes battery fires) is minimised, improving battery safety.

So far, the researchers say the Coulombic efficiency of the battery – the ratio of input charge to output – is over 99 per cent at 150 cycles, but their ultimate target is 99.9 per cent.

"Of all the materials that one might use in an anode, lithium has the greatest potential. Some call it the Holy Grail,"...



And there is a lot more that can be done yet.

Why stay old and dirty and polluting?...

Here is one example of a few pioneering DECADES of exploring the use of better cleaner tech after the spoils of industry:


Turning a slate quarry green: 40 years of Centre for Alternative Technology

Welsh [high tech / green tech] hippies ushered in an era of sustainable living well before the world had woken up to climate change...


If you are in that part of the world, then well worth a visit.

You can treat it like a "garden centre" and enjoy how they have transformed a quarry spoils heap into a beautiful place to live and to demonstrate how to live. Usual really good coffee/tea shop and all supplied and fueled by onsite produce.

Or you can get interested in what they have actually done and easily lose a day or two there, from their various wind turbines high up on the hill, the Pelton turbine that very compactly does more than its fair share of work, down to read beds for purifying drinking water and dry composing toilets and lots more. They even make use of the thermal mass of the spoil heap itself to keep them warmer in winter.

A very good idea is that you can stay there... With that, you can gain some hands-on experience of some of the physical costs of living that most city people are completely unaware of...


Oh... And despite the media stereotype, they look nothing like "hippies".

Unsurprisingly, there is a surprising amount that can be easily done to avoid trashing our world around us. No quarry spoils heaps needed.

Now this is an idea I can get behind and one of the many reasons I have stayed a vegetarian for so long.

Want to have a real impact on climate change? Then become a vegetarian

"Raising animals to eat produces more greenhouse gasses (via methane and nitrous oxide) than all of the carbon dioxide excreted by automobiles, boats, planes and trains in the world combined. Over a 20-year period, methane has 86 times more climate change potential than carbon dioxide, and nitrous oxide has 268 times more climate change potential, according to the 2006 UN report. Radically reducing the amount of methane and nitrous oxide in the atmosphere can produce discernable changes in the greenhouse gas effect within decades, while the same reductions in carbon dioxide take nearly a century.

Yes, quitting meat can reduce your carbon footprint significantly more than quitting driving. "

I ran across this story on the internet. What do you think ?? every little advance in technology helps ??

How A California Company Is Recycling Waste Slag To Deliver A Cheaper Advanced Battery

by Jeff Spross Posted on 4 August 2014 at 12:28 pm

A California firm called Imergy believes it’s hit on a new chemistry that can drastically reduce the costs of certain advanced battery systems.

In this case, it’s what’s called a “flow” battery. Most batteries create an electric current by shuttling ions between two positively and negatively charged solids. Flow batteries use two positively and negatively charged fluids, and create the ion reaction by pumping the fluids across either side of a membrane. This comes with several advantages: they’re long-lasting, they can be built to different scales and uses, and the tanks can be easily swapped to recharge the battery. And because we don’t control when solar and wind power produce electricity, flow batteries and other forms of energy storage will be a critical and widespread part of any grid that relies fully on renewable energy.

The downside of flow batteries is that their liquids currently rely on a solution of a mined material called vanadium — and the purer forms of vanadium that flow batteries require are also used by the steel industry. So the competition and constrained supply make vanadium expensive and hard to come by, which drives up the costs of the batteries. What Imergy did, according to reports by GreenTech Media, was come up with a chemistry that requires less pure forms of vanadium that it can purchase for much lower costs. The company is keeping the exact process under wraps and has filed multiple patents. But the upshot is that, instead of the 99.5 percent purity or higher most flow batteries need for their vanadium, Imergy can get by with 98.5 percent. That means Imergy doesn’t need to compete in the same markets as the steel industry, and instead can buy vanadium that’s been recycled from mining slag, oil field sludge, and other sources that come with a bit more contaminants .......

Is this the beginning of a change of power tech?


Who will kill power companies?...

With Tesla and Panasonic prepping the giant ... GigaFactory, Morgan Stanley has penned an investor note predicting that Elon Musk's big battery footprint will become a major disruptor to power utilities.

It's hardly disinterested, since the financiers were underwriters for a Tesla fundraising round in the past, but it remains an interesting notion: could Tesla also flog batteries to punters wanting storage for their off-grid solar kit, and if so, how would that impact the electricity generation, distribution and retail market...



All a change of power forcing a change of power in the Marketplace?...

Thanks Byron, the vanadium battery story gets ever better.

I wonder if the Musk battery factory is going to include that tech?... One really neat trick is if you could fill up with charged-up vanadium liquid juice just like you can now with petroleum fuels or gas...


Tech quickly moves on... To cleaner better more efficient ways?

A few ideas for the way to go for housing?...


Solar Decathlon Europe 2014 – in pictures

Our pick of the winning and best entries from this year's international competition to design and build solar-powered houses, held in Versailles, France...


Myself, I think the biggest near-term savings would be quickly gained by merely raising the building standards and the intelligence of the builders!

One quick sharp way to do that would be to introduce the requirement of clearly stating the total running costs for any building/apartment... Rather than allowing builders to continue to obscure the true total costs of their cheap fast shoddy builds that are subsequently silly expensive to run and maintain...

So very true. I had to refit my very nice Early American Home in Central Illinois. The builder used only 2 inches of fiberglass in the walls. 20 Below Fahrenheit was not uncommon there in the winter. One day while hosting a party on a windy 20 below day my furnace could not keep up and the temperature in the house kept dropping--I actually had ice forming inside in the living room outside wall.

I added another 12 inches of insulation in the ceiling, Insulated the box sills in the crawl space with 2 inches of urethane and glued Urethane panels to below grade in the crawl space. I also added storm doors to both entrances and taped insulation panels to my sliding doors out to my deck.

My calculations showed that I cut my heat loss in half under those weather conditions. Since I was single then I could keep the house dark by taping insulating panels over some of the windows and could lower the temp with an automatic thermostat at night and when i was at work.
If I were to build from scratch again I would specify 2 by 8 exterior framing with an additional inch of urethane cladding on the exterior walls. Attic insulation to R-40. Low E double pane windows with storm windows and screens. Foam core front doors with external glass storm doors and insulated box sills and insulation to below grade in the basement or crawl space.

A whole house fan venting into the attic would also help in summer energy usage, The attic would also be ventilated with wind-driven turbine extractors as I now have on my current house. My current house has no less than 7 doors to the outside most of them double size or sliding doors. In the summer my electric bill is over 400 dollars per month even with thermostat cutbacks on my three cooling zones and high efficiency HVAC units,
