Ford Fathom moves home-power conversion into the truck
Available bidirectional AC power could simplify home hardware. Backup protection, installation and utility approval remain separate requirements.
A battery-free graphene sensor still needs an energy budget—and a first charge
Power-line harvesting can sustain a tiny sensing load. The startup limitation is essential to understanding the experiment.
NASA’s POWER data links weather to the decisions behind an energy system
A Virginia partnership connects Earth observations with planning. Cooling-degree maps are useful evidence, but they are not a forecast of an electricity bill.
Google’s gigawatt power deal buys flexibility from homes and businesses
The expanded Voltus agreement aims to reduce demand when the PJM grid is strained. A virtual power plant is a capacity commitment, not a new generator switched on today.
Infineon and NVIDIA tackle the conversion chain behind an 800V AI rack
Higher voltage can reduce distribution current. Intermediate converters and protection still have to make that supply usable by computing hardware.
BMW’s 460kW charging demo makes the whole stop more important than the peak
The iX5 demonstration pairs a large battery with a short claimed 10–80% time. Its US charging hardware is still a technology demonstration.
Amazon’s 960MW nuclear plan in Indiana is a proposal, not new power on the grid
Twelve proposed Xe-100 reactors would support Amazon and the regional grid. Development funding, fuel supply and licensing separate the agreement from an operating plant.
