That UAVs can fly brings immediate advantages in terms of how they may travel, and the locations they can reach — often surpassing what’s possible with conventional means of transport. Meanwhile, refinements in computer systems has led to advanced navigation and control systems being embedded within UAV systems — a development that’s been crucial in enabling UAV services to function effectively. With improvements in performance, even consumer grade UAVs are able to carry and deliver small packages over considerable distances.
From the largest of concentrated solar plants, to the most modest of farms in Kenya, the application of 'sustainable solutions' holds the promise of making the world a better place. John’s business, like so many, is one that is threatened by consequences of climate change. In an effort to secure his way of life, and provide for his family, he turned to innovation: “I had to get involved in smart farming because everything used to dry up,” he says.
The United Nations Environment Programme (UNEP) in collaboration with Bloomberg New Energy Finance recently released their 10th Annual Global Trends in Renewable Energy Investment report. The report examines investment in renewable energy technologies such as waste to energy, geothermal, solar, wind, biomass, tidal and small hydropower at a country level. An exciting trend was that developing countries investment exceeded the spend of developed countries for the first time.
There will be a 10 per cent growth in the photovoltaic solar markets around Africa for the coming ten years. This growth, is propelled by a number of factors including government policies that favor adoption of renewable energy, increased environmental awareness for adoption of more renewable energy, viability of these systems as alternatives in powering homes including better costing plans, and the fact that they are becoming cheaper than traditional grid power.
Project Loon the research program with the ambitious vision of delivering global Internet coverage is well underway. And with some luck, by the end of this year we’ll have a great indication of what the project means for the dream of universal Internet access. Project Loon is a flagship of X (previously Google X), the five-year old experimental projects lab fostering so-called ‘moonshot’ projects from Alphabet, the parent company behind Google. By any measure Project Loon is an undertaking of truly global proportions — it involves establishing a fleet of high-altitude balloons that will form a network of Internet-carrying transceivers.
In Kenya 17.3 million people lack access to clean water with water borne diseases like diarrhea and Cholera being the leading cause of death for children under five years. But a group of women have found a low cost method of purifying water, which is now backed by science - embracing seeds from the wonder tree Moringa oleifera.
In late 2004, Kisumu bay, Lake Victoria, was covered in a blue-green hue. The algal bloom - a proliferation of cyanobacteria – demarcated an area of low oxygen and eventually decomposing algae, causing fish to suffocate or flee and contaminating the drinking water- a dead zone. Adapt-N, a software programme developed by researchers at Cornell University seeks to solve this problem.
