| Rebound Technologies | Rebound Technology is rethinking refrigeration through tailored, thermally-driven heat pump architectures that provide efficient, practical, and cost-effective global solutions. Its tailored development approach enables dramatic improvement over the one-size-fits-all, state-of-the-art by utilizing renewable resources, waste heat capture, energystorage, and simple, low-cost construction. Rebound is currently developing two unique and potentially transformative technologies. IcePoint is a refrigeration cycle with embedded thermal energy storage, designed to save supermarkets 60% on their low-temperature cooling costs. SunChill is an ultra-low-temperature thermal cycle, designed for developing world agricultural applications, to convert 50C solar thermal energy into 10C refrigeration using locally sourced materials. Each technology represents a departure from the one-size-fits-all energy approach of the 20th century and instead focuses on tailored technologies that solve smaller problems better. This path reduces the cost of renewable/efficient systems by at an order of magnitude while at the same time growing self-sustaining businesses that create jobs without reliance on government incentives. It is currently funded by US Federal Government research grants. | $1.2M | Seed | Jul 20, 2017 | http://www.rebound-tech.com |
