Practical Engineering explores a scalable (and unexpected) means of mass energy storage.

Electricity faces a fundamental problem that comes with pretty much any product that’s provided on-demand: our ability to generate large amounts of it doesn’t match up that closely with when we need it. The storage of electricity for later use, especially on a large scale, is quite challenging. That’s not to say that we don’t store energy at grid scale though, and there’s one type of storage that makes up the vast majority of our current capacity.

Jamie Paik explores more creative forms of robots.

From the video description:

Taking design cues from origami, robotician Jamie Paik and her team created “robogamis”: folding robots made out super-thin materials that can reshape and transform themselves. In this talk and tech demo, Paik shows how robogamis could adapt to achieve a variety of tasks on earth (or in space) and demonstrates how they roll, jump, catapult like a slingshot and even pulse like a beating heart.

Siraj Raval explores generative modeling technology.

This innovation is changing the face of the Internet as you read this. It’s now possible to design automated systems that can write novels, act as talking heads in videos, and compose music.

In this episode, Siraj explains how generative modeling works by demoing 3 examples that you can try yourself in your web browser.
