SpaceX's Supersized Starship Rocket and the Future of Galactic Exploration | Jennifer Heldmann | TED

SpaceX's Starship launch vehicle has the potential to explore the solar system in a bold, new -- and supersized -- way. Jun 24, 2022 Planetary scientist Jennifer Heldmann talks about how reusable, large-scale spacecraft like Starship could help humanity achieve its next galactic leaps and usher in a new era of space exploration, from investigating the solar system's many ocean worlds to launching bigger telescopes that can see deeper into the universe.

Maldives calls for urgent action to end climate change sea level rise (18 May 2021)

Maldives calls for urgent action to end climate change sea level rise (18 May 2021)

The future of our country, the future of our people, the future of our culture — it all depends on our action today. Aminath Shauna-- MINISTER OF ENVIRONMENT,CLIMATE CHANGE AND TECHNOLOGY, MALDIVES Key points The Maldives could disappear by the end of the century if the world does not act quickly, said the country’s minister of environment, climate change and technology. Aminath Shauna told CNBC “there is no higher ground for us” as the country lies at risk from extreme flooding. The World Economic Forum has estimated that by 2050, 80% of people in the world will be impacted by...

Reversible Power-to-Gas systems for energy conversion and storage

Reversible Power-to-Gas systems for energy conversion and storage

Abstract In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in the reverse direction to deliver electricity during times when power is relatively scarce. Here we develop a model for determining when reversible PtG systems are economically viable. We apply the model to the current market environment in both Germany and Texas and find that the reversibility feature of unitized regenerative fuel cells (solid oxide) makes them...

Reversible fuel cells can support grid economically, Stanford researcher finds

Integrated reversible power-to-gas systems can also convert hydrogen back to electricity as a backup power source surprisingly economically, new research finds.  A major challenge for producers of electricity from solar panels and wind turbines is akin to capturing lightning in a bottle. Both solar and wind increasingly generate electricity amid little demand, when market prices are too low to cover costs. At noon on sunny days, for example, wholesale power prices in areas with high quantities of solar and wind occasionally fall below zero.     A reversible solid-oxide fuel cell system in Dresden, Germany. (Image credit: Sunfire GmbH) Some renewable...
