The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a better, cleaner way to generate the heat we need to make the stuff we want. Learn how his team turned simple bricks and iron wire into a powerful, unconventional "heat battery" that could deliver industrial heat at scale without the emissions — and why he thinks electrified industrial heat is the next trillion-dollar industry. Countdown is TED's global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.

,Mexico City, where Dahua, one of China's leading security tech companies, is launching its products for the Mexican market. On offer here are the latest security cameras, equipped with thermal imaging, facial recognition, the ability to deploy security drones, and all interconnected through 5G technology and the so-called 'internet-of-things'. It's technology that is advancing fast into 'AIOT' - the Artificial Intelligence of Things. Yet in Mexico, that remains a challenge. Increasing 5G coverage in Mexico, and across Latin America as a whole, has been a slow process. Dimitri Flores is a 5G engineer in the telecommunications sector. However, he says that Chinese interest in the region is growing. As 5G rollout continues in Latin America, it's Chinese technology that may bring the region up-to-speed more quickly. __________________ ShanghaiEye focuses on producing top-quality contents.

,At the 29th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP29) held in Baku, Azerbaijan, a package of results was reached on topics such as the new collective quantification targets for climate financing (NCQG) and the global carbon market mechanism under Article 6 of the Paris Agreement. The head of the Chinese delegation stated in his speech that this year marks the 30th anniversary of the entry into force of the United Nations Framework Convention on Climate Change. Over the past 30 years, the governance process of the Convention has faced various challenges; although it has not been smooth sailing, it has consistently moved forward. Humanity is a community with a shared future, and in the face of the climate crisis, we can only unite and cooperate to respond together. __________________ ShanghaiEye focuses on producing top-quality contents.
