so you can use it doesn't build your baby well we'll see if this cook. dinner addition to sparing the environment the new vehicle can move it up to 7 kilometers an hour without using much manpower its ability to power itself is kinetic energy at its best and a big help for users. to. imagine us this when we are by you are working you know and everything is quiet then vital meant to be. cream to achieve this squanto i developed his electric rickshaw unlike noisy diesel truck trucks this version rolls through nairobi almost silently and without emissions it also carries fine of instead of 3 people you want to diversify a product that can utilize what they cannot and emit it can be made it can be in buses wising get there we will be able now to develop one of their major think more beautiful company. you know africa on top of that it's produced sustainably since

components of the electric vehicles come from the region. and how about you if you're also doing your bit tell us about it visit our website also send us a tweet. hash tag doing your bit. we share your story. a lot of the things we use in our day to day life and made from oil wealth to god i was still you were you you was my dog and that was one of the empire exhaust fumes from the cars and plastic for us in the real sense of piling high none of those are just a couple of examples it is a terrible problem scientists are looking for alternatives and sometimes come up with great ideas for that there is a professor at mit was doing. the things we've called.

this building is getting added thermal insulation and damp roofing from polystyrene firm every year over 10000000 tons of the synthetic material are turned into everything from facade cladding to disposable bowls and cups and packaging. but one extremely useful the downside of the material is that it is essentially non-biodegradable and takes centuries to break down and as it does it produces miniscule particles into the ground and our water supplies. this man has a plan to replace the plastic pollutant since 2008. poor and his team have been looking into an environmentally friendly alternative pop corn. similar to polystyrene foam or one if it consists of a mass of calf. he's filled with there are no poor. can see them when you dissect

a piece of popcorn and examine it under the microscope that's what makes it so light. like the market research and his team have already used popcorn to create kitchen furniture they are showing many factories the range of potential applications for popcorn the 1st step is to turn it into a massive granules all the same size the original maize is grown in germany well that is land intensive on the plus side the material will help to reduce fossil fuel consumption. and you can read it and it tastes a lot like popcorn except there's no sugar or salt or chop wood of course so the taste is a bit boring it's. the granules of them pressed together to form sheets or panels with plan pricing providing the bonding agent as opposed to synthetic chemicals this makes the material compostable and even

suitable as animal fodder. the team are pioneers in the field. they also use a horse egg and to compare the thermal conductivity of polystyrene foam to that of popcorn and then measure the heat that penetrates through to the back in the case of polystyrene foam the sensor reads 28 degrees celsius while the popcorn board is even better at absorbing the heat here the reading is under $25.00 degrees. you can cripple houses with the panels in the walls or on the facades also or you can also use them as insulation for solid building. demarc. and the popcorn material also performs better in the flammability test the polystyrene burns up at a frightening speed immediately beginning to melt and release toxic gases.

subjected to the same flame the panel of popcorn barely catches fire. only reason the poor is happy to pass on the fruits of years of research on the material. he hopes to see environmentally friendly products made from popcorn replacing polystyrene foam on a large scale and the sooner the better. of . the 1st popcorn packaging is due to go on the market in the fall of 2021 and will hopefully help to reduce the world's growing mountains of plastic waste. and new technologies can certainly make our life is the one the internal combustion engine was developed in the 19th century no one in the air pollution on serious health issues it will be later that his white many you

know waited for me to finding it will be a waste of pouring machines. when these innovations help to counteract climate change then wait to see for yourself. we bet corn husks aren't uncommon and drowned out these days the current drought has lasted months and the increasingly extreme weather threatens their livelihoods of local farmers especially those in the eastern part of the country who are not quote could be attributed it's apparent that climate change is real and increasingly dangerous the farming seasons that people are used to are not longer predictable at times it trains will one expected drought well brought out instead of rain and it's confusing you can just farm and have hope over having harvest i would even bring the issue and when you aren't paying a couple why you to is one farmer who has been fortunate during these hard times have filled me a river so she's been able to come sufficient water to her crops. but they do so

you need it to pass the pumps is expensive and the exhaust that is a need to the sun's out contributes to a greenhouse effect the researchers and technology experts from a random start up are developed a solar powered irrigation system that they had to project was financed by a u.s. aid organization and they run the government they knew irrigation plants came at just the right time for 40 families from authorities in the district that god made agricultural more difficulty and the cost of renting the diesel pumps nearly consumed on his face. with today's sciences we ended up spending much of what awnings on buying field while using the fuel pump into narrators ira to those little left for our livelihood now we have gotten breed of all those expenses we only need to deplete someone to water

the plugs. of the kurdish just. due to the more affordable. ation promise cannot attend a larger areas of land and keep farming they used a much higher as a result. of what. i did call a hole i was only have a sitting 50 kilograms of these in 2 bags of sorghum it says on now with solar irrigation the yield volume has multiplied by 3 when i am considering expanding my farming even on that one i'll be focused on that solar powered irrigation system should be up and running in all of the party districts in the country by the end of 2021 of the start up that builds the solar irrigation system that's also developed a system to measure the temperature and moisture of the soil sensors calculate the exact amount of water needed by the plants. farmers i've been

notified by and up about when and how much they should water your crops. they pounce and need to get. or what they mean that's why we believe when they use this new technology improves their production. and it does been tested to be a success in the play which fears are being doing. these pilots system is poet based on that energy a swim now the farmers know exactly which plants need water and how much of the need for the time being they improvising with plastic bottles which will soon be replaced by what to horses. it looks like technological advances will be key to all future that is also today's show thank you all for being with us hope to see you again i think we'll be back with more exciting stories about nature and of course the basic i am signed a 3 no deal signing off from the compiler here in uganda. good
