step forward a new type of wind turbine that alasdair keane has been checking out.se turbines are a familiar sight around the world, but when it comes to collecting wind for power closer to the ground and nearer infrastructure, there are problems. but one of the reasons - is that they constantly look in the wrong direction, i because the wind changes so quickly that they can't actually keep up with it, i so they never perform as they could do if they were pointing _ in the right direction. and that's one of the reasons why theyjust don't pay back. - step in katrick technologies and a new type of power generator they have at prototype stage that's already attracting attention. so our wind panels are very unique, and as part of our innovation - and proprietary technology, you know, there's onshore, i offshore wind, as we've seen in lots of other. different wind technologies. but the key difference between us i is we don't rotate, we oscillate. i so our current design is a hexagon. we've got six ducts - and we have a 60—degrees movement with our aerofoils, i and we pic

step forward a new type of wind turbine that alasdair keane has been checking out. sight around the world, but when it comes to collecting wind for power closer to the ground and nearer infrastructure, there are problems. so, close to ground, _ we've got a problem that the wind is on average much less, i but much more turbulent. and the sort of scaling down - the typical wind turbine of the sort of rotor looking into the wind - doesn't work for several reasons. but one of the reasons - is that they constantly look in the wrong direction, i because the wind changes so quickly that they can't actually keep up with it, i so they never perform as they could do if they were pointing _ in the right direction. and that's one of the reasons why theyjust don't pay back. - step in katrick technologies and a new type of power generator they have at prototype stage that's already attracting attention. so our wind panels are very unique, and as part of our innovation - and proprietary technology, you know, there's onshore, j offshore wind, as we've seen in lots of other. differe

alasdair keane's been finding out how.is the most complex technological ice cream product you can make. making a cone product is the food equivalent of making, some might say, a formula 1 motor car. we make them at very, very high speed. we also mix chocolate in there, which is hot and hates water, and ice cream, which is cold and hates fat. so, creating it is a journey. and then, eating a product like that is another beautiful journey. for most of us, thatjourney starts in the shops. ice cream maker wall's have three million of these freezer cabinets all around the world, and now they're on a mission to make them warmer, from —18 to —12 degrees celsius. doing so, they say, will result in a 25% reduction in emissions. this might sound like quite a quick tech solution — but the big challenge for the company is making sure the ice cream tastes the same and has the same texture in the new, warmer temperatures. to find out more, i've come to unilever�*s ice cream research and development centre, a place where they've been inve
