A defense technology company called QinetiQ-which normally makes all sorts of scary robots and surveillance equipment-is now building a portable system that the U.S. military can use in the field to convert trash to energy, sort of like Mr. Fusion from Back to the Future. From the BBC:In the PyTEC system, a large screw-shaped column takes in up to 100kg per hour of untreated mixed waste - including glass and tin, particularly troublesome waste sources for thermal waste approaches. The waste is heated, releasing gases that are removed and used to power a steam turbine. What exits the system is a glassy substance just 5% the volume of the waste that entered, along with 400kW of power. Those are pretty impressive numbers, and the whole PyTEC system (which uses what's called pyrolysis, heating up the trash to release a combustible gas) can fit in two container trucks. This will be really helpful for the military. With a self-contained waste-management system, far-flung bases on the front lines won't have to ship waste out on dangerous roads. But it could do wonders in peaceful contexts, too. If we had these in cities we wouldn't have to drive our trash around and could make some spare energy to boot.

14 images of badass women who destroyed stereotypes and inspired future generations

Throughout history, women have stood up and fought to break down barriers imposed on them from stereotypes and societal expectations. The trailblazers in these photos made history and redefined what a woman could be. In doing so, they paved the way for future generations to stand up and continue to fight for equality.

Why mass shootings spawn conspiracy theories

While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.

When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.

Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.

Satanists put up a billboard in Florida promoting state's abortion law loophole

This article originally appeared on 12.30.20.



In some states, women are put through humiliating and dangerous pre-abortion medical consultations and waiting periods before being allowed to undergo the procedure. In four states, women are even forced to bury or cremate the fetal remains after the procedure.

These government-mandated roadblocks and punitive shaming serve no purpose but to make it more difficult, emotionally damaging, and expensive for women to have an abortion.

Awesome chart shows you how far you can drive on empty.

There are two types of people in this world – those who panic and fill up their cars with gas when the needle hits 25% or so, and people like me who wait until the gas light comes on, then check the odometer so you can drive the entire 30 miles to absolute empty before coasting into a gas station on fumes.

I mean…it's not empty until it's empty, right?

A viral Twitter thread about body autonomy is a reminder of the ‘fear’ and ‘shame’ women still are forced to confront.

Body autonomy means a person has the right to whatever they want with their own body.

We live in a world where people are constantly telling women what they can or can't do with their bodies. Women get it form all sides — Washington, their churches, family members, and even doctors.
