That's true Jeremy, and Dickensman, I agree, I don't think that we have invested enough in tidal power technology (even by today's standards) in the UK.


A lot of new tech in this field has either not been developed at scale or is still in the very early stages of commercial development. It currently competes with the oil industry for shipping needs alone, not easy.


It's a fascinating area of alternative energy that I think will take off in other (non-European) countries before it does here.

New machine converts plastics back to oil


This may well be one of the most revolutionary machines to hit the market, although, in a way, it couldn?t be simpler. Plastic chokes everything. Our water ways, including the Mediterranean. Camels and other animals. And given that it is made from petroleum products, it is a drain on our energy sources.


A Japanese man concerned about the environment his children have inherited dreamed up a way to convert plastic back into oil, reducing carbon emissions in the process. With all the plastic in the world still in existence, and peak oil on its way, plastic (and a machine like this) may soon become one of the world?s most prized commodities.


Conceived by Akinori Ito with the Blest Corporation, this machine can handle all kinds of plastics including polyethylene, polystyrene, and polypropylene. And they can be made in various sizes from small to large that can be used in a range of applications (personal to industrial).

There's nothing new here - the gasification of plastics (or other hydrocarbons) by distillation has been around since the 1920s. See Synthetic Liquid Fuels Act.


This sort of technology won't become feasible before coal-to-oil via the Fischer?Tropsch process becomes economically viable.

as with all others is kinda futile. Mathusian theory re: exponential growth and subsistence is the base to work from. It is not there is not enough oil, its that there are too many humans!!! Its easy to debate peak oil... try debating peak human! For those that find this distatsteful, I ask.. At what point do we take this subject on? When there is not enough food for all classes to survive?

Not if we provide them with the means to produce food, build infrastructure, and generate wealth...

There might be enough for everyone right now. But there won't be enough in the future.

Exponential growth of population; non-exponential growth of food production (and everything-else production).


Interesting story here.


However - my concern is, you get these amazing stories from time to time (e.g. cancer breakthroughs, a cure for AIDS), and then seemingly hear nothing about them ever again. That's what I predict will happen with this. It's like it's too good to be true. So, I remain worried about peak oil.


The government would probably tax this fuel anyway, even if it does get developed, so prices will remain high.

Cella Energy CEO Stephen Voller exhibits his breakthrough technology - right shows the

fuel's hydrogen microbeads under a microscope



Breakthrough promises $1.50 per gallon synthetic gasoline

with no carbon emissions


By Mike Hanlon

05:26 January 26, 2011


UK-based Cella Energy has developed a synthetic fuel that could lead to US$1.50 per gallon gasoline. Apart from promising a future transportation fuel with a stable price regardless of oil prices, the fuel is hydrogen based and produces no carbon emissions when burned. The technology is based on complex hydrides, and has been developed over a four year top secret program at the prestigious Rutherford Appleton Laboratory near Oxford. Early indications are that the fuel can be used in existing internal combustion engined vehicles without engine modification.


According to Stephen Voller CEO at Cella Energy, the technology was developed using advanced materials science, taking high energy materials and encapsulating them using a nanostructuring technique called coaxial electrospraying.


?We have developed new micro-beads that can be used in an existing gasoline or petrol vehicle to replace oil-based fuels,? said Voller. ?Early indications are that the micro-beads can be used in existing vehicles without engine modification.?


?The materials are hydrogen-based, and so when used produce no carbon emissions at the point of use, in a similar way to electric vehicles?, said Voller.

Looking at Cella Energy's technology page reveals precious little that is new here - ammonia-borane has long been known and investigated as a potential hydrogen storage medium.


The only innovation, as far as I can see, is the adaptation of micro-encapsulation, which is otherwise used in scratch-and-sniff perfume samplers - amongst other uses. A quote from the technology page provides perspective:


"Our current composite material uses ammonia borane NH3BH3 as the hydride and polystyrene as the polymer nano-scaffold. Ammonia borane in its normal state releases 12wt% of hydrogen at temperatures between 110?C and 150?C, but with very slow kinetics. In our materials the accessible hydrogen content is reduced to 6wt% but the temperature of operation is reduced so that it starts releasing hydrogen below 80?C and the kinetics are an order of magnitude faster. Although ideal for our proof-of-concept work and potentially useful for the initial demonstrator projects it is not currently a viable commercial material: it is expensive to make and cannot be easily re-hydrided or chemically recycled."

WikiLeaks cables: Saudi Arabia cannot pump enough oil to keep a lid on prices


US diplomat convinced by Saudi expert that reserves of world's biggest oil exporter have been overstated by nearly 40%


http://www.guardian.co.uk/business/2011/feb/08/saudi-oil-reserves-overstated-wikileaks

I've been thinking about this... not just oil, but fossil fuels in general. And then I read an article about Dale Vince and Ecotricity.


Lots of people on here talk a good talk, but has anyone put their money where their mouth is and signed up with a green electricity supplier?

Yes.

Quids, after a friend posted this image on *another district forum*, there was a suspension, for ever.... [nervous titter]



Of course, now the news from Saudi has appeared in the Grauniad, all good sandal-wearers should be nervous, but they probably already were. The problem is with the Express and Sun and Mail readers.

Ecotricity.


Some considerable time ago, I went for a 'fair's-fair' supplier, not green unfortunately. The idea: no quarterly charge, no-more-expensive-for-those-who-use-less. Because it's fairer for the less well off, for those who use pre-paid etc.


But I finally decided that green generation is now more important than any other consideration.

    • What "stricter" consequences could there be for shoplifting (or any other crime) than being put into jail, do you think? Though our prisons are of course full enough already, without more people being shoehorned  into them.
    • Returning to the original question, I had my jabs at Tessa Jowell yesterday. I was early and I was  seen on time, and it was a lovely pharmacist who did them, but the admin beforehand (not by her) was a bit iffy. I was given forms to fill in but not told what to do with them afterwards, so I  presumed I had to take them into the consulting room, as the rest was supposed to be filled in by a clinician, but no! After some time had elapsed and I had found a seat (there was no information on where to sit either, so people were sitting in two separate areas, neither of which had many seats) my name was called and  the forms were taken behind the counter. Be aware if you don't have an appointment - even in the relatively short time I was there, three people turned up without appointments having been sent there by a GP (I presume) or having  previously been  asked by the pharmacy to come  back at a different time, and they were all sent away again because the pharmacy didn't have enough flu vaccine until the following day. I have no idea if this was due to a misunderstanding on the people's side, their GP's or the pharmacy's, but none of them were very happy, and one lady said she "couldn't keep coming back" 😭  At least one of them didn't seem to understand what he was being told, possibly due to a language issue. I felt quite sorry for the pharmacist, who was giving jabs all day on top of her usual workload but still managing to stay cheerful! Though she wasn't the one dealing with the unhappy people! I have a sore arm from the Covid jab (I chose to have the jabs in different arms), but no other ill effects so far, touch wood. 
    • Line speed and the strength of your Wi-Fi signal are two separate things.  The first is determined by the type of connection (fibre/copper etc) to the outside world and the second is the connection between the device (printer/TV/laptop/tablet etc) and the router. If you are connecting a device to the router using cables (as Alec1 is) then this is will give the best possible connection but isn't practical for many without a degree of upheaval and even then not all devices (tablets for example) will allow a wired connection. So you relying on the quality of the Wi-Fi signal from the router to the device and this will depend on the quality of the router, the type of Wi-Fi connection (the frequency), line of sight etc - many different things.  This is why some people opt for a "mesh" type setup which is supposed to give a solid quality of Wi-Fi signal around the house with little or no blackspots.  It's expensive though and still requires the devices that send and receive the signal (like the plug-ins you have) to be wired to the router.
    • We have had a few cat flaps over the years but none have been electronic. They just have a small clip that you turn to lock or open.  Some come with a magnet and a matching magnet that the cat wears on its collar  This prevents other cats entering.  I've not used these as I don't like the idea of a cat wearing a collar. Cats do like to be out at night and you need to encourage yours to return after a late evening sortie. Calling,rustling treat wrappers worked for ours but he seems to have now got into the habit of coming back about 9pm. without this.
