The world's most entertaining and useless self-help guide, from the brilliant mind behind the wildly popular webcomic xkcd and the #1 New York Times bestsellers What If? and Thing Explainer
For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.
Bestselling author and cartoonist Randall Munroe explains how to predict the weather by analyzing the pixels of your Facebook photos. He teaches you how to tell if you're a baby boomer or a 90's kid by measuring the radioactivity of your teeth. He offers tips for taking a selfie with a telescope, crossing a river by boiling it, and powering your house by destroying the fabric of space-time. And if you want to get rid of the book once you're done with it, he walks you through your options for proper disposal, including dissolving it in the ocean, converting it to a vapor, using tectonic plates to subduct it into the Earth's mantle, or launching it into the Sun.
By exploring the most complicated ways to do simple tasks, Munroe doesn't just make things difficult for himself and his readers. As he did so brilliantly in What If?, Munroe invites us to explore the most absurd reaches of the possible. Full of clever infographics and amusing illustrations, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.

Using a nuclear reactor to generate heat to generate electricity to generate heat seems very inefficent. Using a coolant loop from the reactor into the lava would definitely increase the efficiency significantly, and if you only use 1 loop, now you've got radioactive lava. Absolute win.

An easy way to get the lava is to go to the nether and bring buckets of the stuff back, then use a shovel to dig a 5 block wide 3 block deep pit around your house, then fill it with lava. Just make sure you're not fully reliant on it since someone could just build over it.

UGH I WISH I SAW THIS BEFORE MAKING MY EVIL LAIR! had to settle for a circle of shark infested waters instead EDIT- I have made this comment 10 months ago and am still getting replies so I will update you. The sharks are a difficult balance between feeding them too much and starving them, I would be careful managing their bloodthirst without risking their health. As a downside of my inexperience I have been overfeeding them at first and my heroic nemesis made her way into my lair, there was a lot of fighting and monologuing. As an upside we are married now, both evil, and both have learned from the past security issue. With 2 villains in a lair the amount of heroes doubled, so now I don't have to feed the sharks myself much at all

From personal experience, I would recommend piranhas. They require less work and are cheaper. Plus, sometimes sharks leave your enemies alone end they can swim to safety. No such issue with piranhas! Then again, you could, of course, splice the genes of the sharks and the piranhas to make a new creature but that’s just too expensive and time consuming (rather than visitor consuming)

@@ordinaryshiba Actually no, you can stand right next to lava just fine; even walk over it with minimal damage if you're quick enough at the point of contact, thanks to the leidenfrost effect (too slow and you'll sink in and be in for a seriously bad time, so, don't do it). In Hawaii, I think it was I saw video of, there have been people who have taken lawn chairs and sat them beside a lava flow and roasted weenies over the lava on long metal rods. It IS really quite hot still, obviously, but air is a terrible conductor of heat. Iron is a pretty poor conductor of heat, as well, taking it on slowly and dispersing it very quickly. If you've ever seen a blacksmith working on an iron ingot, you'd see just how quickly it cools down, and how even while eye-searing red hot, you can still be right beside it and not burn up. And the layer of lava right against the bucket walls would cool down rapidly and form an insulating layer between the molten core and the rest of the bucket, reducing the thermal energy conducted to the bucket further.

We can also make fresnel lens circle above the moat to at least keep it hot at day hence reducing power demand.

The final suggestion of using geothermal won’t be easy. The challenge with using geothermal to melt rocks is finding a suitable liquid to transport the needed energy. You would need something that would phase transition at over 1200°C at some reasonable pressure, and then you would need some even higher melting point material from which to fabricate the piping and heat exchangers needed. Copper pipes aren’t going to cut it!

@MinutePhysics 4 жыл бұрын

The final solution is to use geothermal to generate electricity in the normal way, then heat the lava with the electric heating coils as normal :)
