Climate change is natural and normal but human activity would appear to be affecting <strong>the rate</strong> of climate change.<br /> 2. If you make a reasoned hypothesis based on empirical evidence or previously proven knowledge then that theory stands until disproven; That's what a theory is. This is how science works. Anyone taking this logical and sensible route is a "scientist". If you have no knowledge but choose to come up with a theory based on what you heard in a pub you are a fool. If you insist people listen and act upon this theory then you are a dangerous fool.<br /> 3. There is no for or against climate change. There is neccesary research into the extent to which we may be affecting it and what we can do to avoid affecting it detrimentally.<br /> 4. There are innevitably political reasons for whipping up hysteria such as raising fuel prices and surpressing industrialisation of developing countries.</p> <p>Having said all that: A girl walks into a cocktail bar and asks for a Double Entendre, so the bar man gives her one. </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-57899 Fri, 18 Feb 2011 09:01:52 +0000 yamashow 57899@http://newsbiscuit.com/forum/ <p>There are thousands of Scientists on Johnny (he's on the) Ball side too .<br /> maybe people should stop trying to brainwash people.</p> <p><a href="http://www.youtube.com/verify_age?next_url=http%3A//www.youtube.com/watch%3Fv%3Dh8EUtB45RvE" rel="nofollow">http://www.youtube.com/verify_age?next_url=http%3A//www.youtube.com/watch%3Fv%3Dh8EUtB45RvE</a></p> <p>This video is straight out of a right wing dictatorships library. </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-57896 Fri, 18 Feb 2011 08:53:25 +0000 Sinnick 57896@http://newsbiscuit.com/forum/ <p>You've got a point, Garry, with Johnny Ball on your side, whinging about his lost career, and 100's of thousands of true professional scientists on the other side, you may be onto a winner.</p> <p>Maybe, just maybe, JB should be spending some of his enormous intellect on understanding why a very small minority of folk just cannot get to grips with the problem. It's not an intelligence issue, it's an emotional issue - the problem is so enormous and out of our experience that it's easier to go for the comfortable option that human-caused Climate Change doesn't exist.</p> <p>Now that politicians are starting to understand the enormity of the problem, the remaining sceptics are irrelevant.</p> <p>PS, for other readers, I suspect industrial nanotechnology is 10-20 years away, and therefore not a pragmatic solution. It has to be today's technology that cures this blight we've created - and that has to be nuclear or massive arrays of solar cells; wind, wave and tide just aren't enough for future energy demands. </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-57883 Fri, 18 Feb 2011 05:43:06 +0000 yamashow 57883@http://newsbiscuit.com/forum/ <p><a href="http://www.dailymail.co.uk/news/article-1358139/Climate-zealots-life-hell-sceptic-says-Johnny-Ball-victim-porn-blog-smears.html" rel="nofollow">http://www.dailymail.co.uk/news/article-1358139/Climate-zealots-life-hell-sceptic-says-Johnny-Ball-victim-porn-blog-smears.html</a> </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-57011 Thu, 10 Feb 2011 22:28:34 +0000 theumpire 57011@http://newsbiscuit.com/forum/ <p>Surely the turbo encapulator must be the answer to our energy problems.</p> <p><a href="http://techcrunch.com/2010/04/30/science-to-the-rescue-the-turbo-encapulator/">Click here for more info.</a> </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-57010 Thu, 10 Feb 2011 22:22:57 +0000 yamashow 57010@http://newsbiscuit.com/forum/ <p>I agree with Golgo that piece was quite interesting ,I am interested.I wonder if a pair of testicles can be seen through those German windows ? maybe that is their selling point!<br /> gerade ein Gedanke </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56992 Thu, 10 Feb 2011 20:55:27 +0000 Rowly 56992@http://newsbiscuit.com/forum/ <p>@Golgo.<br /> wish I was the author, i would be paid more than I get.<br /> Totally agree about the low cost, low output developments emerging.<br /> my guess is that many technologies will become viable within a few years.<br /> @ALOpecia.<br /> proves my point.

Boron reacts with water to release copious hydrogen which can be used in internal combustion. This technology is already at the demonstration stage - essentially solar furnace technology is at the heart of the system, and the car would carry boron and water. </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56966 Thu, 10 Feb 2011 17:23:54 +0000 Oxbridge 56966@http://newsbiscuit.com/forum/ <p>Now he's Rowly. 5 down, 7 to go... </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56906 Thu, 10 Feb 2011 12:17:31 +0000 Golgo13 56906@http://newsbiscuit.com/forum/ <p>@ Rowly - Thanks, interesting article. Are you the author? </p> <p>I'd never heard of these. Certainly sounds like they've got some hurdles to overcome, though. Do you know if any companies are involved in/investing in the development, or is it just academia at the moment...?</p> <p>There are a few other potentially disruptive technologies coming from the opposite direction promising ultra-low production cost, acceptable efficiency, (who needs high efficiency if you can churn out material at 10c/Wp, right?) </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56901 Thu, 10 Feb 2011 11:44:42 +0000 Rowly 56901@http://newsbiscuit.com/forum/ <p>@ Yam &amp; Golgo<br /> The development I was referring to was Nano "antennas" which vibrate at the frequency of the light absorbed &amp; produce a high frequency electric current.<br /> Standard PV cells use the energy of a photon to knock an electron off the semiconductor.<br /> so the new "antennas" method is potentially much more efficient.<br /> The length of the Nanotube(s) can be made to suit the wavelength of the light to be harvested, including infra red, which will help to minimise problems with scattering.<br /> these could even work in the dark!!<br /> one of the big problems at the moment is being able to make nano rectifiers which can operate efficiently at the very high (light) frequencies.<br /> This again comes down to silicon technology.things can be done in the Lab, but getting them into production at a viable cost needs much more work.<br /> <a href="http://www.newscientist.com/article/mg20827915.000-is-night-falling-on-classic-solar-panels.html" rel="nofollow">http://www.newscientist.com/article/mg20827915.000-is-night-falling-on-classic-solar-panels.html</a> </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56833 Wed, 09 Feb 2011 21:59:51 +0000 Golgo13 56833@http://newsbiscuit.com/forum/ <p>@rowly. If it's the multijunction indium gallium arsenide/phosphate etc( compound semiconductor) ones you're on about they can get over 40% efficiency in the lab on very small areas, but the materials and manufacturing techniques are still really expensive so the default is still silicon, with cadmium telluride panels in second place. Only 15 ~ 17% energy conversion (170W per m^2) for silicon, and about 11% for CdTe, but much much cheaper to make.<br /> GaAs/InGaP has been used on space craft where power per weight is the issue rather than cost. For terrestrial applications, you can concentrate (lenses or mirrors) sunlight onto small chips of the stuff so you can get more solar energy onto less of this super expensive material, but then you need direct (not diffuse) sunlight, and you need a tracking system to make sure the sun's light stays focussed on the chip of photovoltaic material as the sun moves across the sky. The lenses and tracking system add cost etc etc. And you need 300+ days of clear skies because you can't focus light on a cloudy day.<br /> You could have huge CPV systems in the sahara and then a big fat cable to Europe. But even then silicon or cadmium telluride might still be cheaper. </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56824 Wed, 09 Feb 2011 21:08:52 +0000 yamashow 56824@http://newsbiscuit.com/forum/ <p>Rowly thanks for the info on the panels,what is taking so long with the nano? </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56819 Wed, 09 Feb 2011 20:05:17 +0000 FormerlyAlOPecia 56819@http://newsbiscuit.com/forum/ <p>Well Stoop your name is a bit of a give-away... </p> http://newsbiscuit.com/forum/topic.php?id=20488&page=3#post-56817 Wed, 09 Feb 2011 20:04:17 +0000 StoopyDeGunt 56817@http://newsbiscuit.com/forum/ <p>Damn.
