Question of the Week : Energy
Will We Ever Recharge Electric Batteries As Quickly As We Get Gas?

Stanford University researchers have developed a machine learning-based method that cuts battery testing times by 98 percent. The team says that their A.I. technique could lead to a future where an electric battery is recharged in the time it takes to stop at a gas station. Watch...

Question of the Week : Energy
Will Rain Become a Viable Energy Source?

Our lead INSIDER story today demonstrated the power of a droplet energy generator – specifically the system’s ability to light up 100 LEDs with just a small amount of water.

This approach is a cost-effective way to convert carbon dioxide gas into methane.
Electric motors and gas-alcohol engines could slash pollution levels and greenhouse gases from long-haul trucks.
Heartbeat-based biometrics, sonic-boom displays, and an artificial leaf.

Question of the Week : Mechanical & Fluid Systems
Will Wave-Powered Desalination Catch On?

Today's lead INSIDER story demonstrated how ocean waves can be used to turn seawater into freshwater.

A new device, inspired by a rose, inexpensively collects and purifies water. The device is a new approach to solar steaming for water production — a technique that uses energy from sunlight...

Question of the Week : Energy
Does Snow Have Power Potential?

A 2019 Tech Briefs story demonstrated a plastic-like, flexible nanongenerator that creates electricity from falling snow.

Briefs : Electronics & Computers
Low-Cost Thermoelectric Material Works at Room Temperature

The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. A new material was developed that...

Scientists from Caltech and Northwestern University have found a way to generate electricity by combining saltwater with one of life's more undesirable compounds: rust.

Technique Identifies Electricity-Producing Bacteria

Certain species of bacteria that exist in oxygen-deprived environments must find a way to breathe that doesn't involve oxygen. These microbes — which can be found deep within mines, at...

The National Energy Technology Laboratory (NETL) is a U.S. Department of Energy (DOE) national laboratory — with sites in Anchorage, AK; Albany, OR; Morgantown, WV; and Pittsburgh, PA...

Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...

The increased use of photonics has the potential to reduce CO2 emissions — by 3-billion tons.
A new water purifier works better because it takes the shape of the rose.

Solar power researchers have traditionally only used the power measurements from single residential solar photovoltaic (PV) systems to estimate the...

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places. But...

Briefs : Manufacturing & Prototyping
Using Laser Metal Printing to Cool Computer Chips

Traditionally, electronics are cooled using a heat sink that transfers the heat generated by the electronic system into the air or a liquid coolant. For the heat sink to work, it has to be attached to the CPU or the graphics processor via a thermal interface material such as thermal paste. It...

Wood-Based Technology Creates Electricity from Heat

Researchers have transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) on which the human body runs. This energy is generated using charged channel walls and other unique properties of the wood’s natural nanostructures. With...
