addis leads a team of half a dozen or so at his home in blantyre.deas. this skeleton car will be on the road next month, i'm told, powered in part by steam. this tin can electric car uses phone id for security. and that's just one sim card that that works with? even addis‘s pottery wheel helps power things up. so, has anybody before called you a mad professor? with all of this stuff? well, yes, i've got quite used to that! in the heat of the day, i've come to see a prototype addis is particularly proud of. well, this is the zero electric climate control system. the main thing here is what i call the cooling element. 0k. where it takes water and it presents it to the environment, right? so the heat and the environment help it evaporate. that process cools things down. it sounds very simple but there is a bit more to it than that, isn't there? here we have formulated materials that already are folded up so tightly that they shrink a large amount of space into a very small space, right? at nano scale. when we put water into it, that water can be spread

is how quickly malawi's two main cities, the capital, lilongwe and the commercial centre here in blantyreght going on. do you want to know more? well, how long have you got? researchers are developing artificial intelligence, creating smart homes, predicting health problems and making old computers work again — for the whole continent. in some ways, malawi's cities look and feel like many others, there's plenty of shops and services, new buildings are going up, but importantly, there's a real need here for more simple tech that makes life better without the need for power. only a fraction of the country's actually on the power grid and even those who have it, well, historically it's been unreliable, demand far outstrips supply. and it gets hot here as well. in summer, even now at a cooler time of year, it gets up to the mid 20s. i'm on my way to meet a very cool inventor who specialises in sustainable tech. hey, adis, thanks for having us over! hi. nice workshop. adis leads a team of around half a dozen or so at his home. all sorts of things are being hacked together here. it's a mashup o
