Carbon Monoxide

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists employing a smart dual-method process.

Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels.

Researchers have created a new alloy made up of not two, but five different metals, and put it to work as a catalyst. The 2D material was able to convert carbon dioxide into carbon monoxide, potentially helping to turn the greenhouse gas into fuels.

Over the last few years humans have tried to mimic nature with artificial leaves, but they’re never quite up to scratch. Now, researchers have designed a new version that could work under real-world conditions, sucking carbon dioxide out of the air and creating oxygen and synthetic fuels.

Researchers at MIT have developed a new membrane-based system that can convert carbon dioxide emissions into useful alternate fuels. The process has been effectively demonstrated on a small-scale and the researchers hope to ultimately adapt the system to conventional fossil fuel-based power plants.

The humble leaf, which collects sunlight and uses that energy to turn carbon dioxide into fuel for the plant, has inspired scientists. Researchers have developed a molecule that uses sunlight to convert the problematic carbon dioxide into carbon monoxide, which can then be stored as a fuel source.

The new Ryobi Ultra Quiet Garage Door Opener can double as a carbon monoxide sensor, wireless speaker, fan or parking assistant if you're open to mixing and matching the brand's plug-and-play modules.

Not content with vacuums and fans, Dyson is expanding into the realm of air purification with its Pure Cool purifier fan, which was unveiled today. Building on the company's Air Multiplier technology, it's designed to filter ultrafine particles, which are a major component of air pollution.

The DUSTBOT project recently demoed two multifunctional robots aimed at keeping town streets clean and door-to-door garbage pickup.
