The haliade—x, unveiled in 2019. it is a monster of a machine, this thing. and i want you to describe for me its scale and efficiency, and how you get it to work. so, the haliade—x is the worlds most powerful wind turbine in operation today. its offshore, it has a iii—megawatt capacity, and the rotor — so, the distance from blade tip to blade tip — is 220 metres. so each blade is longer than the wingspan of the largest aircraft in the world. each spin of one of those blades can power a...

Now, danielle, i want to come back to you to hear about your latest prototype wind turbine, the haliade—x, unveiled in 2019. it is a monster of a machine, this thing. and i want you to describe for me its scale and efficiency, and how you get it to work. so, the haliade—x is the worlds most powerful wind turbine in operation today. its offshore, it has a 14—megawatt capacity, and the rotor — so, the distance from blade tip to blade tip — is 220 metres. so each blade is longer than the ...

From the material. now, in terms of the limitations, if we look at the optimum efficiency a single solar absorbent material could be, like silicon, they top out at about 25%. thats really the practical limit for an actual solar panel with todays silicon technology. so, im hearing 6%, 7%, 8% from danielle. im hearing 20% from you. were not quite at that 85%. and all of this energy we generate needs storing, doesnt it? so, kristian, i know that youre a man of the fjords and boats and ships have be...

Two solar cells on top of each other. and the perovskite we tune to match perfectly silicon. it absorbs only the visible light and we left the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so weve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, triple junction, three junctions, that would top out at just above 50%....

Of low—cost photovoltaics, he discovered a thin film of photocells. it could be a hugely significant discovery, as henry hopes it will eventually double the efficiency of solar power and halve the cost. danielle merfeld is an electrical engineer who is chief technology officer and vice—president of ge renewables. ge is the biggest creator of wind turbines worldwide, and she and her team currently have over 40,000 wind turbines out in the field. shesjoining us by video link from north carolin...

Enough to mitigate the spread? are you concerned that there is a gap time here between those that remain unvaccinated not sufficiently being tested frequently enough to catch those that may actually have the delta variant or other incoming variants? >> we are specifically concerned about that. as a consequence, were requiring it twice weekly in certain settings. recognizing the efficiency of transmission of the delta virus. youre right. in jails and acute settings, skilled nursing facilities, th...

Thank you. now, danielle, i want to come back to you to hear about your latest prototype wind turbine, the haliade—x, unveiled in 2019. it is a monster of a machine, this thing. and i want you to describe for me its scale and efficiency, and how you get it to work. so, the haliade—x is the worlds most powerful wind turbine in operation today. its offshore, it has a 14—megawatt capacity, and the rotor — so, the distance from blade tip to blade tip — is 220 metres. so each blade is longe...

Multi—junctions, and the simplest mult—junction is a tandem cell, two solar cells on top of each other. and the perovskite we tune to match perfectly silicon. it absorbs only the visible light and we left the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so weve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, t...

To match perfectly silicon. it absorbs only the visible light and we let the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so weve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, triple junction, three junctions, that would top out at just above 50%. so what perovskite does is lift the ceiling for potential efficie...
