The National Energy Technology Laboratory (NETL) is known for its far-reaching array of experiments.
It’s now wrestling with what may be its toughest one: how to stimulate the technologies for three new industries to capture, transport and store the climate-changing emissions of fossil fuels.
Until recently, removing CO2 from flue gas has been difficult, expensive and often frustrating. While the invisible gas has the power to warm the planet, it is a relatively small ingredient of power plant emissions, ranging from as little as 4% of the flue gas from natural gas-fired plants to 15% of coal-fired exhaust. Carbon dioxide is also hard to separate from accompanying nitrogen and hydrogen.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
