39 Ways to Save the Planet - Slippery Ships

While at sea or in port, the hull of a ship can be an attractive new residence for all sorts or creatures. The initial slime build-up can provide a welcome mat for more and more creatures. This 'biofouling' can end up being inches think and heavy in weight as well as stopping the streamlining of the vessel. The drag caused can result in more fuel being needed to keep the ship moving forwards at the same speed - more cost and more carbon.

Tom Heap meets a new stowaway on ships which will help fight the build up. Paint company Jotun has now developed the Hullskater robot. Monitoring of conditions will alert when the robot needs to be deployed on missions - with its magnetic wheels and high definition cameras it inspects the surface and uses brushes to remove the build up.

With an increasing fleet of ships, Dr Tamsin Edwards from Kings College London also reflects on other measures to keep hulls free of build up and alternative fuels that might help the international fleet reduce its carbon impact.

Everything Everywhere Daily - DEFCON

Historically, an army would have days, weeks, or even months to prepare for war. However, with the development of intercontinental missiles and nuclear weapons, the time for preparation was reduced to hours or even minutes. In light of these changes, it was necessary to develop a system that allowed for rapid mobilization and readiness. Learn more about the DEFCON system, and the history of its level changes, on this episode of Everything Everywhere Daily.

39 Ways to Save the Planet - Polluter Pays

There are already examples around the world where the manufacturer helps to pay for the safe disposal of waste from their goods once used - such as electronic items or bottles. But what about the carbon dioxide produced from fossil fuels?

Tom hears about the 'Carbon Take Back Obligation' concept - in which oil and gas producers would have to capture and store C02 - ratcheting up from 1% of what they produce by 2023, to 10% in 2030 and 100% by 2050. Some say it's impossible to meet the aims of the Paris Climate Agreement without it.

But where would all that carbon dioxide go? How much storage space would we need for it and how much of the cost would trickle down to the petrol pump?

Dr Tamsin Edwards of King's College, London, armed with statistics gathered by the Royal Geographical Society, joins Tom to add up the numbers.

Everything Everywhere Daily - Longitude

Navigation on the open ocean is extremely difficult. It is a skill that takes years to master. Even with years of skill, an experienced mariner was still able to ground their ship on an unseen reef, underwater rocks, or a sandbar, because they didn’t know their precise location. The main problem, which was unsolved for centuries, was determining your longitude. Learn more about the longitude problem, and how it was eventually solved, on this episode of Everything Everywhere Daily.

Everything Everywhere Daily - The Tallest Structures Throughout History

Standing next to an extremely tall structure can be an exhilarating experience. Something which was no less exhilarating to early humans. Ever since humans created the first pile of rocks, we have been trying to build ever-larger piles of rocks. These piles of rocks eventually evolved into structures hundreds of meters tall. Learn more about the structures which have held the title of the tallest in the world, on this episode of Everything Everywhere Daily.

Bay Curious - How Bay Area Homelessness Compares Globally

Many people in our community are experiencing homelessness -- about 35,000 throughout the Bay Area at last count. Matthew Schmitz was shocked by how wealth and poverty exist side by side when he moved to the Mission District of San Francisco. He wanted to know how homelessness here compares to other places around the world.

Curious City - Art, Protest And The Trial Of The Chicago 8

In 1969, Chicago was home to one of history’s most high-profile trials. Known as the Trial of the Chicago 8 — and sometimes the Trial of the Chicago 7 — the trial pitted anti-war protesters against the federal government. Eight men were accused of conspiring to incite a riot during protests that took place in Chicago during the Democratic National Convention of 1968. Outside the courtroom, protesters and onlookers gathered. Some chanted to free the men. Some came with signs and posters of protest and solidarity. In this episode, reporter Arionne Nettles explores the intersection of art and protest movements as she tries to track down the artist behind one of these posters.
