Many EVs carry enough battery capacity to power a house, but doing so requires vehicle-to-home (V2H) compatibility, a bidirectional charger with a DC-to-AC inverter, and an islanding or transfer switch. Without that specific hardware, energy cannot flow backward from the car into the home, regardless of battery size. The report also distinguishes V2H from vehicle-to-load (V2L), which only powers individual devices rather than an entire household.

E-ink technology uses electromagnetic principles to create paper-like screens that can display static images without drawing power, giving ereaders battery life that can span weeks or months compared to days for tablets like the iPad. The underlying mechanism is rooted in basic physics, though the precise chemistry and electronics involved are complex and limit how competitive e-ink devices can be against mainstream tablets.

6K, a 12-year-old startup based in North Andover, Massachusetts, said Thursday it received conditional approval for a $250 million Department of Defense loan to build a battery materials factory in Tennessee. The plant will use the company's microwave-based plasma process to produce cathode material without relying on Chinese suppliers. 6K had previously secured a $50 million Energy Department grant in 2023 that the Trump administration later canceled, pushing back the factory's original 2024 opening target.

Slate has replaced its original dual-battery lineup—a 52.7kWh NMC pack from SK On and an optional 84.3kWh version—with one 205-mile LFP battery made by Gotion in Manteno, Illinois. The change keeps the truck's starting price at $24,950 plus a $1,450 destination fee, though the 205-mile range is still a projected estimate pending final EPA certification.

A consumer tech guide explains that slowing performance and poor battery life on older Android phones is often due to a degraded battery rather than a failing device. It recommends replacing the battery—often for $10-$80 depending on repair method—rather than buying a new phone, and suggests using built-in battery-saving modes and keeping charge levels between 20 and 80 percent.
