nick kwek went to marseille to meet him.about a frenchman's garage. we're in our workshop. it's where we do all our research and development. a formerjet ski world champion, frankky zapata has been at the forefront of water—powered vehicles for decades. he has been beavering away for years on several airborne inventions. i started with this prototype in 2011. two years after, i got the idea of the hoverboard. and then we got the idea to create the flyboard. this is self balancing. you just press the trigger and you fly. but recently he has developed a penchant for rocket fuel. this bad boy has five jet engines packed tightly together to blast franky into the stratosphere. well, maybe not that high, but it can reach a top speed of 110mph. we have a plan b for everything. plan a, plan b, plan c for electronics. and you can lose an engine. so if one of these five engines blows... you can lose two engines and keep flying? the explosion would be contained by some kevlar protection. the explosion? if it explodes. it can hold someb

that was nick kwek in australia. that's it from us for this week.ell, where you'll find loads of extra tech news and behind—the—scenes photos throughout the week. thanks for watching, and we'll see you soon. hello there. temperatures over the last few days have been topping out around the middle—20s celsius. warm enough, you might think. but for some over the next few days, we'll have values up into the 30s. increasingly warm and humid through the day ahead. some sunshine, but also a fair amount of cloud in places, because, as you can see from the earlier satellite picture, we've got this pipeline of cloud just ploughing its way in across the british isles. and western areas particularly, where you're exposed to that moist south—westerly flow, seeing a lot of cloud to start off thursday. some rather misty, murky conditions for some coasts and hills. bit drizzly in places, the odd shower here and there. but for north—east scotland, and certainly for a good part of england and the south—east of wales, we start the day with some sunshine, and these are

nick kwek went to see one such project at the most famous coral reef in the world.rld. earth's largest living thing, sprawling some 1600 miles. but this paradise could soon be lost at the hands of a very surprising vandal. crown of thorns starfish eat coral, and although they're found here naturally, recently too many have been pouring in at once due to major weather events and ocean pollution. you would think a starfish would be a cute, gorgeous thing you would see on the great barrier reef. the crown of thorns starfish, not so much. they're spiky, ugly, they can have up to 20 or 30 arms. the biggest issue with crown of thorns starfish is that they can eat up to one metre of coral per day. when they're in plague proportions they can absolutely devastate a reef. to the rescue, the ranger bots. these underwater drones autonomously scour the reef starfish and prick them with a deadly dose of biosalt. the bots use an algorithm to identify starfish and then target them. their developers say they're 99.4% accurate. and they get smarter with time. traditionally, divers ha
