is the name of a genetically modifi ed mosquito of which 750 million are planned to be released in the Florida Keys in 2021 and 2022 The blood suckers have been modifi ed to produce female off spring that will die in the larval stage in order to decimate the population of the insects carrying diseases such as Zika and yellow fever Will this type of bioengineering on which hundreds of scientists around the globe have been working for ten years be a benefi cial innovation or genetic Russian roulette Critics warn that the project is a Jurassic Park experiment because potential long term consequences have not been adequately investigated Roughly a third of the worldwide energy consumption and counting is used for buildings So any idea that helps curb this trend is welcome Engineers are pinning great hopes on semiconductor solar cells with perovskite crystal coatings The coated areas in the nanometer range of thickness are so fl at and transparent that they can be placed between the panes of double glazed windows where they work in two ways When the sun shines the perovskite crystals rearrange themselves fi rst into chains then into plates and fi nally into cubes Each new shape progressively tints the glass and reduces solar irradiation This automatic tinting eff ect takes place within just a few seconds But the real kicker comes when the panes are dark and the window turns into a solar cell producing electric power That s when the crystal palaces of modern big cities will become solar power stations At the moment this is still pie in the sky but scientists at the National Renewable Energy Laboratory NREL of the U S Department of Energy are planning to build an initial prototype by fall of 2021 The German Fraunhofer Institute is investigating this technology as well OX5034 Sun catchers The best way to have a good idea is to have a lot of ideas Nobel Prize in Chemistry winner Linus Pauling Failure is an option here If things are not failing you are not innovating enough Tesla CEO Elon Musk I love those who yearn for the impossible Universal genius Johann Wolfgang von Goethe At fi rst innovations are massively overrated but in the long run they re massively underrated Former Area VP of Microsoft Germany Achim Berg They always say time changes things but you actually have to change them yourself U S pop art icon Andy Warhol Words to remember 9 Global
