British Sikh engineer, Navjot Sawhney gave up his lucrative career to go and work in India, to use his skills to help solve problems for rural communities. While there, he became fascinated with the problems his neighbour, Divya, was facing while handwashing clothes, sometimes for up to three hours a day.

Broadcaster and journalist Nkem Ifejika finds out how Nav promised to design a hand crank, off-grid washing machine for his neighbour, to help her avoid the sore joints, aching limbs, and irritated skin she got from her daily wash.

Within two years of coming up with the idea, Nav had set up his own company, The Washing Machine Project, and trialled his first machine in a refugee camp in Iraq. From that first trip, over five years ago, the project has now provided nearly a thousand machines, free to the users in poorer communities and refugee camps, in eleven countries around the world.

Nkem hears how seven years on, Nav fulfilled his promise to return to India with a machine for his neighbour, Divya.

The Washing Machine Project is now partnered with the Whirlpool Foundation, the social corporate responsibility arm of the company that designed the first electric domestic machine over a hundred years ago, and together they hope to impact 150,000 people.

Nkem asks if a project like this can really make a difference, given that roughly five billion people still wash their clothes by hand.

Communication is a human right - but what happens when someone can’t speak for themselves?

Sean Allsop struggled to talk until he was eight years old, when he began to speak thanks to years of speech therapy. He explores the technologies and innovations helping people around the world who struggle to communicate.

We meet Richard Cave, National Advisor at the Royal College of Speech and Language Therapists, as he introduces a patient and their family to voice banking, a method that preserves someone's voice before it's lost, using recordings to create a personalised synthetic version. He explains why having your own voice is a major part of your identity.

In the United States, we hear from people trialling a brain chip that turns neural signals into speech. It's still in its early stages, but how close are we to seeing this kind of technology more widely available for those who would benefit from it? A child-friendly robot made in Luxembourg is teaching children with communication difficulties how to express emotions and build social skills. And in San Cesareo, Italy, the simplest solutions can sometimes prove the most effective. The town has introduced AAC (Augmentative and Alternative Communication) sign boards in public spaces, helping both users and non-users learn and connect.

What if reimagining how cities are designed could make women safer? In Cairo, sexual harassment and violence against women on the streets has been endemic. Women don't feel safe enough to walk or take public transport. A pioneering programme called Safer Cities, is hoping to find the solution through radical urban redesigns, women friendly spaces and raising awareness about sexual harassment. Salma El-Wardany, who was born in Cairo, visits a women’s only park in Imbaba, Giza and meets Samaha who runs the park. She not only oversees the children playing, but also organises events for local women with advice and support. Salma visits Zenein Market in Giza, which was redesigned to better support the majority of female sellers there. They show Salma the older part of the market which is yet to be regenerated. Salma also speaks to Caroline Nassif, who worked as Project Officer at UN Women, as well as local NGOs, and Minister Manal Awad Mikhail who was one of the driving forces behind the scheme across locations.
