Why Norway's Osmosis Power Plant Failed

8m 10s

When seawater and freshwater mix, a surprising amount of energy is released. Norway tried to capture this energy using an osmotic power plant, but the plant mysteriously and abruptly shut down. Join George as he tries to figure out why using dialysis tubing, toilet parts, and a baby turbine.

    Hot Water Freezes Either Faster or Slower Than Cold Water

    S11 E4 - 13m 59s

    The Mpemba Effect happens when hot water freezes quicker than room temperature water, or does it? Alex goes on an exhaustive journey to replicate the Mpemba effect and hits a few snags on the way, including a paper being released the week this video was supposed to come out. Does this paper finally resolve all existing ambiguities about measuring relaxation speeds in the Mpemba Effect?

    Why a Carbon Capture Breakthrough Will/Won't Save Us

    S11 E3 - 9m 56s

    Chemists have been pulling carbon dioxide out of the air for almost 300 years, but can this seemingly magical technology save us from climate change? George answers that question with a couple of Erlenmeyer flasks, some limestone, two envelopes, and a straw.
