• Steel has been made essentially the same way for thousands of years, by using carbon as a chemical reductant. Today, that process is responsible for about 8% of global CO2 emissions. Boston Metal has developed a game-changing electrolysis process for making steel. In their Molten Oxide Electrolysis (MOE) cell, an inert metallic anode is immersed in an electrolyte containing iron ore. The result is a clean, high purity liquid metal that can be sent directly to ladle metallurgy — no reheating required.

  • The current generation of AI hardware (TPU, GPU, CPU) is not optimized for edge AI especially as the complexity of tasks and memory requirements increases. Femtosense has developed a 2D array of tightly coupled digital compute and memory blocks that exploit
    network sparsity coupled with an algorithm that trains networks to expose their underlying sparsity while maintaining performance. This coupled hardware and algorithm approach allows Femtosense to deliver the AI performance of large models in constrained edge platforms.

  • mmWave is critical to the future of all wireless technology, but the realization of its potential faces severe roadblocks. Weak uplink, high deployment costs, low 5G radio efficiency and soaring operating costs are all combining to thwart the promise of mmWave. Currently, 5G networks are being held back from realizing their true potential due to a critical missing component: high-performance mmWave power amplifier technology. High-performance GaN-on-Silicon (GaN-on-Si) brings a new option to the table that could make 5G millimeter wave more practical. Finwave’s award-winning 3DGaN technology improves linearity, output power and efficiency in 5G mmWave systems – while reducing costs for carriers.

  • Hedron is building a network of data relay satellites that will help solve the connectivity problems faced by remote sensing constellations. Earth Observation (EO) satellites spend 70% of their orbits in connectivity blackout zones, forced to hold their critical data onboard until the next downlink opportunity. With leading multi-aperture optical technology, Hedron is building the infrastructure that makes high bandwidth, low latency connectivity to space a reality.

  • Fat is the single most important sensory component in meat, but the plant oils currently used in meat alternatives lack the physical properties and flavor of animal fat. Hoxton Farms combines cell biology and mathematical modeling to produce cultivated animal fat, the key ingredient that will unlock meat alternatives that look, cook, and taste like the real thing.

  • Today, businesses use an energy-intensive technique called separation to filter out the valuable methane from other gases. That often requires using fossil fuels to boil off the unwanted chemicals.  Osmoses, a Massachusetts Institute of Technology spinoff, has created a membrane material thinner than human hair to reduce carbon emissions from industrial processes such as natural gas production.

  • Modern agriculture faces increasing challenges due to climate change and population growth. Humanity needs to produce more food to sustain a growing population while significantly reducing emissions. Current methods to improve crops are severely limited by development time and cost. Phytoform’s technology significantly speeds up trait development and implementation, producing new plant traits in months rather than years, and at a fraction of the cost of conventional breeding and GMO technologies.
