"Light Poverty" is a debilitating condition that adversely affects over 1.4 billion people in the world. Light Poverty directly impacts the quality of life and the impact is more skewed for the marginalized and weaker sections of society in developing and emerging economies.  The problem worsens when it comes to global issues such as climate change and sustainability.  Light Up Africa Inc. (LUA) a social enterprise in the renewable energy sector, is working to improve access to energy for the marginalized and weaker sections of the world.  We are developing the Zoom Box, a portable electricity-generating device, which generates electrical energy through kinetic motion and stores the electricity within the box to be consumed when needed. The Zoom Box is a sustainable, affordable and reliable solution for the marginalized who need the electricity the most.The Zoom Box is the most effective solution to bridge the energy gap for rural communities without access to the electrical grid. The Zoom Box harnesses kinetic energy and its converts it to electricity to be consumed when needed. Creating energy through motion is not a new idea, but making it affordable for the people who need it and at such a scale is unique. Applying this technology in the form of a personal device designed specifically to attach to bicycles, motorbikes, livestock, and boats is an innovative idea. The Zoom Box’s ease of use and compatibility with any moving object such as a pedestrian walking, bicycles, motorcycles, livestock, and boats provides a significant competitive advantage. LUA is more than a business idea – it is a movement. LUA is the dream of many and is led by a motivated, committed and professional team comprising of business professionals, engineers, and volunteers – each one bringing a unique skill set to LUA.LUA is inspired by its vision to bring reliable and affordable electricity to everyone in the world and is driven by its mission to improve the quality of life of the impoverished while aiming to make the world a more sustainable place by bringing reliable and affordable customized technologies to underdeveloped regions in the world.   Passionate about changing the world?  Are you a visionary who wants to have an opportunity to work for a startup?  Send us your resume at [email protected]

It’s not a debate. There’s no two sides. A post-pollution world is inevitable. Humans will either be part of it, or the planet will go on without us. In other words, it’s defossilize or die. But where others see a dire choice, LanzaTech sees a trillion-dollar opportunity. The good news is after 15 years, north of a thousand patents, and millions of hours of pioneering scientific inquiry, LanzaTech has invented a technology big enough to meet the moment. One that transforms pollution into profit, and ensures that humans continue to prosper far into the post-pollution future. The science is state-of-the-art, but the idea is simple. We use nature to heal nature. First we capture carbon emissions. Then we feed them into bioreactors where trillions of carbon-hungry microbes go to work. These tiny dynamos eat the pollution and output valuable raw material commodities. Pure enough to be resold, repurposed, recycled, renewed, re-everythinged — from sustainable jet fuel to yoga pants. It’s a commercial scale solution that’s ready for market today. In a crowded sector filled with speculation but short on results, our plug-and-play platform is already making our customers money. Turns out science and business makes one helluva team. Waste carbon pollution is humanity’s biggest threat. LanzaTech is turning it into an opportunity. Reducing emissions and making money for our customers — today. Let's transform our tired Lose-Lose climate debate into a Win-Win proposition. One that helps companies grow their revenue while helping the planet reach a post-pollution reality.

Solar Simplified is an online platform that matches renters and homeowners who care about the environment and want to save money on the electricity bill with local solar farms. We take the hassle out of supporting renewable energy and make the sign-up process easy and transparent. For developers, Solar Simplified is a sales and marketing jackpot. The company was started and designed by a team with deep tech and marketing backgrounds. We chose to start a platform democratizing solar because we are obsessed with the energy space, worried about the state of the planet, and want to use our skills to help propel the country (eventually the world!) into mass solar adoption. And because of our broad experience, we are able to guarantee solar farm developers full subscription of their farms when working with us. As a startup, we are excited to begin gaining traction and trust in the industry as we continue to expand our developer partnerships and support people looking to access the benefits of solar energy.
