U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

A recent United Nations provision has banned the use of mercury in spacecraft propellant. Although no private company has actually used mercury propellant in a launched spacecraft, the possibility was alarming enough—and the dangers extreme enough—that the ban was enacted just a few years after one U.S.-based Mercury is a neurotoxin.

New analysis finds Asia produces twice as much mercury emissions as previously thought

Green Car Congress

New analysis by an international team led by MIT researchers shows that Asia now releases a surprisingly large amount of anthropogenic mercury. The new analysis provides more accurate estimates of sources of mercury emissions around the world. The team’s top-down analysis improves on other models that take a bottom-up approach.

Dell’s Bold Idea: A Laptop You Can Actually Repair

Cars That Think

Consumer electronics can cause deadly pollution by degrading into hazardous materials (including lead, mercury, and arsenic) when left in landfills. Framework, a startup that released its first laptop in 2021, is already putting this idea into practice. And climate change isn’t the only problem worth worrying about.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. The wire had become a “superconductor.” The extremely low temperatures and high pressures needed to induce superconductivity limited its practical value for decades.

Exposure to airborne metal pollution associated with increased risk of mortality

Green Car Congress

These samples are analysed in the laboratory to measure the presence of 13 elements: aluminium, arsenic, calcium, cadmium, chromium, copper, iron, mercury, sodium, nickel, lead, vanadium and zinc. The metals deemed to be of anthropogenic origin were cadmium, copper, mercury, lead and zinc.

A Brief History of the World’s First Planetarium

Cars That Think

In 1912, Oskar von Miller , an electrical engineer and founder of the Deutsches Museum , had an idea: Could you project an artificial starry sky onto a dome, as a way of demonstrating astronomical principles to the public? The task of realizing those ideas fell to Bauersfeld, a mechanical engineer by training and a managing director at Zeiss.

[PRESS RELEASE] DRIVE ELECTRIC RESPONSE TO CLEAN CAR DISCOUNT CHANGES.

Drive Electric

With recent policy changes ending ideas like social leasing and scrappage schemes, we need new ideas to enable all New Zealanders to access EVs. One idea would be to look at encouraging corporate fleet owners to take up EV, as these fleets usually have lifespans of 2-4 years before they are sold.”
