Twenty finalists for a $1 million prize set up by the Ruler of Dubai were revealed on Monday, ahead of an awards ceremony in September. The group of start-ups will deliver their pitches for the Global Maker Challenge, against a backdrop of economic struggles and poverty linked to the coronavirus pandemic, organisers said. The shortlisted 20 have harnessed technologies such as machine learning, artificial intelligence, smart materials or cloud networks that could help disadvantaged communities around the world. Finalists include companies with products that connect farmers in the developing world with international buyers, and inventors of fibres that could cut pollution and waste in the global fashion industry. The Mohammed bin Rashid Initiative for Global Prosperity, which runs the challenge, said the finalists were selected from more than 3,400 entries. "Innovation is key to controlling the damage caused by Covid-19 and bringing us back to speed towards a more sustainable future," said Badr Al Olama, head of the organising committee for the Global Manufacturing and Industrialisation Summit, which hands out the prize each year. "We must double up on our efforts in utilising innovation to address humanitarian challenges and offer solutions to the unprecedented challenges caused by this crisis." The 20 finalists were chosen by Massachusetts Institute of Technology’s Solve initiative and a jury of 47 judges from UN agencies and charities, as well as academics. Final pitches will be made to judges online because of the pandemic, and will focus on the social impact of their products and campaigns. Last year, at the GMIS summit in Yekaterinburg, Russia, four companies were handed $100,000 each, while the 12 runners-up were awarded $10,000 each. India's A2P Energy Solution created a way to turn paddy straw, which is widely burnt off in India generating huge pollution, into pellets to be used in renewable energy. Canada's Rumie Initiative created a learning platform that required virtually no internet connection to use. TruTrade impressed judges with its ability to connect smallholders to sustainable food markets in Sub-Saharan Africa, improving their businesses and families' lives. And India's Garv Toilets was named winner of the Sustainable Cities challenge for its plan to provide low-income urban communities with low-cost sanitation, the lack of which has huge implications for public health and hygiene.
