  • There’s two types of military SONAR: active and passive. Active SONAR is using pings and listening for the echo, but it’s not very commonly used by submarines. Passive sonar is just listening out for engine noise from ships and prop noise from other submarines. Warships use active SONAR more because they’re already noisy and so if they think an enemy submarine is in the area they’ll use it to try and locate, but in peacetime it’s mostly reserved for training exercises. It’s still terrible for wildlife, even if they don’t die it’s very distressing and disorientating but it’s not constantly scanning like a RADAR.







  • I heard an idea once about making minimum wage 0$ and giving everyone a liveabke UBI. That would mean that nobody is required to participate in the workforce, meaning that employers who can’t afford to pay their workers a good wage would be priced out of the market rather than being able to prey upon peoples need for, y’know, money (which can be exchanged for goods and services). A very appealing idea for a 16 year old boy, and the only issue I see with it now is extreme specialisation in the workforce leading to less competition between different workplaces for similar jobs.
