Moving Mountains

London Eco Startups London ECO FRIENDLY STARTUPS UK Green Startups London UK moving mountains

Moving Mountains is a big, bold and powerful metaphor that maps to the brand’s massive and seemingly impossible goal of living in harmony on a sustainable planet, as well as a daily affirmation in the form of the plant based diet, food and human health.

Simeon, the founder & CEO of Moving Mountains®, is a Vegan and a firm believer in the plant based diet, as well as being a lifelong passionate supporter of environmental issues. Simeon set about to develop a company that could make a real and long-lasting positive change and disrupt the animal agriculture food industry that is responsible for the majority of the earth’s resource destruction.

It all started after a routine blood test at the GP, which returned Simeon with a high cholesterol reading. The GP’s responses were to cut out meat and dairy or go on statins. Already a Vegetarian at the time Simeon was surprised that dairy products could cause so much damage to the human body and decided to follow more of an overall plant based diet from then on.

Starting with the Moving Mountains® Burger, Simeon spent two years in development laboratories with a dedicated team of scientists and chefs to create the ideal tasting product. Hundreds of recipes have been tried and tested to achieve the final result of the burger that’s available for everyone today.

Riding Sunbeams

Riding Sunbeams is a world-leading innovator founded by climate charity Possible and Community Energy South. Our corporate mission is focussed on decarbonising rail traction networks through the development and connection of unsubsidised, direct-wire renewable generation with significant social impact for line-side communities. 

We were the first to achieve this globally through our pioneering FOAK 2019 project (funded by Department for Transport) which connected solar energy directly into Direct-Current, third rail powered railways, in conjunction with Network Rail at their Aldershot site. We have now received funding on FOAK 2020 to both develop and demonstrate the required technology to connect solar energy and line-side energy storage to feed an Alternating-Current, overhead-wire railway.

Our commercial model uses external finance and a Power Purchase agreement to minimise or eliminate capital outlay for transport operators such as Network Rail, with the cost of purchasing the green energy being offset by a reduction in energy purchased from the comparatively carbon-heavy grid. Riding Sunbeams estimate that each MW of solar capacity connected the rail traction system will deliver annual carbon savings of around 245t/CO2e.
