Liquid hydrogen (LH₂) is attractive for long-distance energy transport because of its high volumetric energy density. But even well-insulated tanks cannot completely prevent heat from entering. As the liquid warms, hydrogen evaporates and pressure builds, leading to boil-off losses during stora...
Modern tomatoes are a breeding success story. Generations of selection have made them bigger, firmer, more productive and easier to ship. But that progress came at a cost.
