tend to focus on the big cities on ways to reduce traffic congestion and pollution and of course make life better on you give me basis on what you think you have and what took you off because well it's not something i'm really up to you know a simple it was developed you take. these handcuffs off and why several 100 kilos and here in kenya's capital nairobi exhausted noise are another problem for day laborers. kenneth quantize invention could make life easier it's an electric our consciousness goes faster and can carry more be bold enough to stand up to. the kind of silver charge where you wish to kill it and that's it but if you're looking to get more people who know these people to challenge you so you think you know isn't useful and doesn't bother

you well we'll see if this book. in 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 for the big help for uses. this on the ground by you are working you know how everything is pathetic wired then vital meant to be. green to achieve this quantized you tell it to the electric rickshaw unlike noisy diesel took 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 emitted can be made it can be in buses while we will be able now to develop one of their major electric more beautiful companies. you know because 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 websites oh send us a tweet. hash tag doing your best. we share your story. a lot of the things we use in our day to day life on live from oil well figure was still as you view was modelled and this is but for the entire exhaust fumes from the cars and plastic for us in the field since opining high. and those are just 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. much the things we've called.

this building is getting added thermal insulation and damp roofing from polystyrene for 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 in one consists of a mass of cavities. filled with air. 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're 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 eat it it tastes a lot like popcorn except there's no sugar or chocolate of course so the taste is a bit boring and. the granules have been pressed together to form sheets or panels with plum prophesying 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 used 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 vicenza 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 fit wooden houses with the panels in the walls or on the facades. or you can also use them as insulation for solid building. demarc. tiriel 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. or 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 lives easier when 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 waiters call me to the finding it will be a waste of pouring machines. when these innovations help to counteract climate change then wait to see for yourself. we that con house aren't uncommon in ground are these days the current drought has lasted months and they increasingly extreme weather threatens the libel hood's of local farmers specially those in the eastern part of the country or no 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 route instead of rain and it's confusing you can just farm and have hope over having harvest and what it will bring issues and when you aren't paying a couple. is one family who has been fortunate during these hard times have filled arnie a roof so she's been able to pump sufficient water to her crops. but they do so you

needed to power the pumps is expensive and the exhaust that is a need to sends out contributes to a greenhouse effect the researchers and technology experts from a random start up 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 difficult and the cost of renting the diesel pumps nearly consumed the needs. with them as a 2 day sciences we ended up spending much of what awnings on buying sherl while using the fuel pump into narrators ira with those little left for our livelihood now we have gotten great of all those expenses we only need to deplete someone to

water the plants. of the kurdish just. due to the more affordable. mission promise cannot attend a larger areas of land and keep farming they yield a much higher as a result. i did call a hole i was only harvesting 50 kilograms of these in 2 bags of sorghum it sees 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 party districts in the country by the end over 2020 the startup that builds the sun at 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 their crops. the plants need to get the optimum or what's being and that's why we believe when they use this new technology to improve their production. and it does been tested to be a success in the play which has not been doing. these pilot system is powered by solar energy a sweat and now the farm is not exactly which plants need water and how much they 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 old the today show thank you all for being with us hope to see you again next week we'll be back with more exciting stories about nature and of course of a should i am stunned at the no guilt signing off from compiler care in uganda. it's
