Balcony solar is a trend where couples of solar panels are hung over apartment balconies, tied into a small battery pack and plugged into a home outlet to provide instant apartment power backup, and is currently only taking hold in parts of Europe like Germany rather than in the US

Ambient Photonics demonstrated a bifacial solar cell integrated into a streaming box remote (like Amazon Fire TV) that can charge effectively whether placed face up or face down

Shelly has released new Gen 3 devices that are approximately the size of a quarter and include both miniaturized relay controls and standalone energy tracking devices for monitoring power consumption of outlets and appliances

Ambient Photonics' dye-sensitized solar cells can capture full spectrum light from compact fluorescent lights, LED lights, and ambient sunlight in a room and convert it to electricity

OrCam Hear is a hearing loss assistance device that looks like ordinary earbuds but uses sophisticated technology for targeted noise cancellation via a companion smartphone app

Anker's SOLIX line includes the F3800 Portable Power station that starts at 3.84kWh and can scale to 26.9kWh with 6 modules, and multiple stacks can be combined for a total of 53.8kWh of storage

Ambient Photonics has developed a dye-sensitized solar cell (DSSC) technology that achieves 3 to 5 times better power density performance than typical DSSC cells, enabling practical battery-free operation for consumer devices

Matt Ferrell has been struggling with burnout related to making videos for his channel, involving significant time, effort, stress, and anxiety that came to a head in late 2023

90kWh of energy storage from EcoFlow's Delta Pro Ultra could provide backup power for approximately a week for most American homes

CES 2024 felt different from previous years because it had fewer vaporware and empty promises, with more substantive technologies actually ready or near-ready for market

Traditional solar cells linked together in series lose all power output if even one cell is shaded, whereas Ambient Photonics' uniform single cell technology maintains power regardless of partial shading

Devices with Ambient Photonics solar cells would use fewer materials, be longer-lasting, and more robust compared to devices that require periodic battery replacement

Bosch announced they will be releasing a hydrogen-burning engine for transportation

Hyundai announced a new version of their Nexo hydrogen fuel cell vehicle

Anker demonstrated the SOLIX Solarbank E1600 with 1.6kWh of storage capacity, which while not large, could be stretched far for apartment applications
