Default Passwords Jeopardize Water Infrastructure

Cars That Think

Drinking water systems pose increasingly attractive targets as malicious hacker activity is on the rise globally , according to new warnings from security agencies around the world. Last November, for instance, hackers linked to Iran’s Islamic Revolutionary Guard broke into a water system in the western Pennsylvania town of Aliquippa.

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. In Warren’s own telling of the story , his first attempt at an electric chronometer was a crude motor that connected the gears of a clock to the Boston Edison electrical system.

million in Carbon Recycling International (CRI). Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2.

How to Build a Power Grid on the Moon

Cars That Think

Now the company means to solve the power problem on the moon with a service that can collect solar energy at the poles, where sunlight is never far away, and distribute it to places sunk in darkness. This grid is designed to deliver power where it’s needed via a fleet of robotic rovers. Think of it as a robotic extension cord.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. In mid-2022, the International Renewable Energy Agency counted 32 countries that had adopted hydrogen strategies and 11 others that were preparing such plans.

Engineers Are Working on a Solar Microgrid to Outlast Lunar Nights

Cars That Think

Therefore, a power grid will not simply keep the lights on and air pumping but also support the mining and fuel-processing facilities that will concurrently work to reduce the supply requirements from Earth. The Sandia engineers therefore are looking at two direct-current microgrids, with a tie-line connecting them.

US and Japan collaborating on smart grid project in Hawaii; EV operation and charging, including grid-balancing services

Green Car Congress

These technologies will be implemented to eliminate factors causing power voltage impacts in the distribution grids and fluctuations in power frequency when large volumes of renewable energy with weather-dependent tendency are added to a power grid. The committee will also discuss international standards.
