Gravity is such a pesky thing. It prevents us from doing all sorts of wonderful things. Such as floating through the air like a balloon, traveling into orbit without paying an ugly cost in delta V, and being morbidly obese but still light on your feet like Baron Vladimir Harkonnen. By the same token, it would also be incredibly useful to be able to create gravity

Gold extraction

2018 10 3ensp;0183;ensp;Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold.
