Home batteries are usually a stack of separate boxes: an inverter, one or more battery packs, a controller and a lot of wiring. On November 9, 2026, in Palma, Spain, Huawei announced the LUTERRA S2, an all-in-one residential energy system that folds a hybrid inverter, storage and AI energy management into one stackable unit. The company says it can be installed and commissioned in minutes.
This article is based on Huawei's launch announcement. The performance figures below are the company's...

Big range of behaviors for tiny graphene pores
Researchers at MIT have created tiny pores in single sheets of graphene that have an array of preferences and characteristics similar to those of ion channels in living cells. The surface of a single cell contains hundreds of tiny pores, or ion channels, each of which is a portal for specific ions. Ion channels are typically about 1 nanometer wide. By maintaining the right balance of ions, they keep cells healthy and stable. Like biological channels, graphene pores are selective for certain type...

Rubber That Can Use Energy from body movements to Generate Power
Power-generating rubber material could harness walking and other movement to charge electronic devices.
Researchers at Princeton University have recently invented a new energy-harvesting rubber material composed of ceramic nanoribbons that could harvest energy from your breathing and walking.
This material is composed of ceramic nanoribbons embedded onto silicone rubber sheets which generates electricity when flexed and is highly efficient at converting mechanical energy to electrical ener...
