E Ink tablets rely on reflective displays rather than backlit or emissive screens, making them easier on the eyes and far more readable outdoors than most iPads, aside from the high-brightness iPad Pro. Devices like the reMarkable Paper Pro also offer longer battery life and lighter builds because their screens only draw power when content changes, unlike an iPad's continuously lit display.
Reflective, a nonprofit funding solar geoengineering studies, published a research roadmap for stratospheric aerosol injection outlining what scientific work is still needed before governments could make informed deployment decisions. The plan estimates coordinated research would take about a decade and cost roughly $370 million, versus 20 years and nearly $1.4 billion if uncoordinated, and it recommends conducting outdoor experiments releasing sulfur dioxide into the stratosphere.
A 2017 explainer describes impedance matching, the engineering technique of adding a component to help a system absorb energy more efficiently rather than reflecting it. It illustrates the concept with examples ranging from car transmissions and electrical transformers to sloped beaches and anechoic foam spikes.
