Engineering with Rosie - Electricity Across Oceans: Is HVDC the Future? 11072023

How can we connect power grids across long distances or across seas and oceans? The answer is high voltage direct current, or HVDC, interconnectors. In this video Rosie explains how these differ to regular AC, alternating current transmission, the recent technology advances that are causing HVDC interconnectors to start popping up all over the place, and what challenges remain to be solved if we are going to connect places as far flung as Europe and North America.

Engineering with Rosie - Are Flow Batteries About to Take Over? A Lab Tour of RedFlow's Zinc Bromine Battery 25052023

Engineering with Rosie - Solar Power at Night using Concentrated Solar Power (CSP) 30032023

Concentrated solar power (CSP) uses mirrors (heliostats) to focus sunlight to heat up a solar receiver and heat fluid (usually molten salt storage) that can be stored for later. It has been around for literally thousands of years, but is still a hot new technology for the energy transition. In this video, Rosie talks about how CSP works and the different technology options: power tower, parabolic trough, Fresnel reflector and dish.

Engineering with Rosie - Ultimate Climate Hack or a Recipe for Disaster? 25042023

The dinosaurs were wiped out by an asteroid that hit the earth and caused rapid global cooling from the sulfuric aerosols dispersed by the impact. Rapid cooling sounds like just the ticket to UNDO global warming... Can we artificially recreate the cooling effects of the asteroid’s impact to erase the effects of climate change?
