What's most interesting about his discovery is that the three metals form a very light alloy, about 40% lighter than a Lithium Ion battery pack at the same size (for example, a Prius battery weights 317 kg, while this hydrogen tank would only weight 200 kg).

There are materials that can trap relatively large amounts of hydrogen, at normal pressures, but by now they all […]

But practical reality tells a far different story today: Diesel/ distillate fuels (including jet fuel) do all the heavy lifting on this planet-for good reason. That’s because distillates […]
