>Harnessing the Sun’s energy is one of the cleanest ways to generate electricity on Earth. It does, however, come with an obvious limitation. Once darkness falls, solar panels stop generating electricity, creating a gap between when energy is produced and when it’s often needed most. To bridge the divide, a team of scientists may have found a way to capture and store energy from the Sun, extending its use into the night.
>Researchers from China redesigned the internal structure of wood, converting it to a porous sponge that can absorb sunlight and store it as heat. The engineered material can be used to generate electricity from solar energy even when the Sun is no longer shinning. The findings, [published](https://advanced.onlinelibrary.wiley.com/doi/abs/10.1002/aenm.70872) in Advanced Energy Materials, could help overcome solar power’s most glaring weakness.
Im all for finding cool ways to use solar thermal energy but this seems like a waste of time. the article immediately points out a better solution – batteries, and then goes on to give zero details on how much power was stored in their super delicate and hard to make wood thingy. Oh and if batteries seem not great for some reason we also already have pumped hydro.
Another dead-end tech, it generated basically nothing worth of energy and proved less cost-effective than batteries.
