The Fence Tourists Love to See

- Adam Clare

Down in New Zealand there’s a fence that people go out of their way to see. This fence was the first of its kind and was built to keep invasive predators out while conserving native species. The fence was built a couple decades ago and was specially designed to protect threatened species in New Zealand that were becoming prey to everything from cats to small mammals. Birds are loving it because their nests are protected while they can still fly away and gather food.

The sanctuary has become a significant tourist attraction in Wellington and is responsible for the greatly increased number of sightings of species such as t?? and k?k? in city’s suburbs.

Sometimes described as the world’s first mainland island sanctuary in an urban environment, the sanctuary has inspired many similar projects throughout New Zealand, with predator-proof fences now protecting the biodiversity of many other areas of forest. Examples include the 7.7-hectare (19-acre) lowland podocarp forest remnant of Riccarton bush/Putaringamotu, the 98-hectare (240-acre) Bushy Park, and the 3,500-hectare (8,600-acre) Maungatautari Restoration Project enclosing an entire mountain.

In Cold Weather, Heat Pumps Outperform Fossil Fuel Furnaces

If you don’t already have a heat pump then you’re going to want one ASAP. These machines that act as heaters in the winter and air conditioning in the summer are already more efficient than traditional AC units. Now, the current version of heat pumps even outperform fossil fuel furnaces in the cold of winter. At their core heat pumps transfer heat from one space to the next which means they can be anywhere from 200-500% efficient compared to the paltry 98& efficiency of a planet-killing fossil fuel burning fossil. If you own a home then you really should get a heat pump because we need to stop burning fossil fuels as soon as possible.

Efficiency measurements don’t measure comfort, explained Gibb, but he said there are consumer surveys showing those who use heat pumps fare well in cold temperatures. A 2022 consumer analysis in Europe found 81 per cent of respondents said their comfort improved after installing a heat pump. Another study conducted in New York and Massachusetts, which installed monitoring equipment in heat pump users’ homes, found 32 of the 42 people who participated said they were more comfortable post-heat pump.

Desalination on the Cheap for the Masses

Water water everywhere and plenty of drops to drink. Researchers from MIT have found a way to passively convert seawater into drinking water using a setup so simple it seems too good to be true. Their device basically uses heat from the sun rays and a siphon. The apparatus produces more water and rejects more salt than other passive setups, it can generate five litres of water if the device is one square meter in size. All of this with no external energy. They have even tested the device in open water – and it works! Imagine hundreds of these devices floating on the ocean bringing drinking water to cities.

The heart of the team’s new design is a single stage that resembles a thin box, topped with a dark material that efficiently absorbs the heat of the sun. Inside, the box is separated into a top and bottom section. Water can flow through the top half, where the ceiling is lined with an evaporator layer that uses the sun’s heat to warm up and evaporate any water in direct contact. The water vapor is then funneled to the bottom half of the box, where a condensing layer air-cools the vapor into salt-free, drinkable liquid. The researchers set the entire box at a tilt within a larger, empty vessel, then attached a tube from the top half of the box down through the bottom of the vessel, and floated the vessel in saltwater.

In this configuration, water can naturally push up through the tube and into the box, where the tilt of the box, combined with the thermal energy from the sun, induces the water to swirl as it flows through. The small eddies help to bring water in contact with the upper evaporating layer while keeping salt circulating, rather than settling and clogging.

Be My Eyes, Be My AI

- Adam Clare

The visual impaired population is getting more support from AI to help them ‘see’ the world around them. The already very successful human-powered app Be My Eyes (we’ve covered it before) has launched Be My AI, an automated tool that can help in certain circumstances. Using an AI trained to identify everyday objects users can use the camera on their phone to quickly identify objects, of course it isn’t perfect and nor can it fully replace the human aspect of Be My Eyes. One user has written up their experience of the tool which you can read here.

You can use Be My AI 24/7 in all those situations when you want quick visual assistance without necessarily calling a human volunteer. Be My AI is perfect for all those circumstances when you want a quick solution or you don’t feel like talking to another person to get visual assistance. You may be amazed that Be My AI knows more than just what’s in the photo – just ask for more context and discover what it can tell you.

Be My AI also will give deaf-blind users a new way to get information if they use, for example, a braille display. Be My AI’s written responses are user-selectable in 29 languages.

For all of its advantages, though, Be My AI does not and should not replace a white cane, guide dog, or other mobility aid that provides for safe travel.

Expand Houses by Shrinking Lanes

- Adam Clare

Seemingly everywhere there’s a crunch on housing and there’s a surplus of roads, so let’s change some car space to sleeping space. If we take away even just one lane of parking for cars we can create towers of housing for people. Cities can benefit from increased revenue since housing makes more money for cities than stationary cars. What’s more, when a developer wants to build and take away a lane then part of the development fees can be specified to increase transit and biking infrastructure.

He argues that highway conversions make more sense than using lanes on regular city streets for housing, at least in most cases. “Most street right-of-ways are can only be reduced by a lane or two, which can generate enough extra space for a bike lane or expanded sidewalk but not enough for the addition of housing,” he says. “Moreover, trading street width for a housing tract typically requires a public/private land swap. These are possible, but add enough red tape to only make sense when a significant amount of housing can be added.”
In Boston, Speck’s firm is working on a plan, now in its second design phase, to use excess road space in Kenmore Square to add new housing and public space. “The plan results in considerably more housing than originally conceived, plus a beautiful plaza,” Speck says. The plan would also more than triple the space available for pedestrians.
