Can someone explain this to me please. What is “energy” measuring here? How is it different from power?

"You see what I did there? Paving. Get it?"

Right. Now unleash the academic peer review puns. They've given permission.

Naive, back of the napkin is 446 kWh / m^3. There’s a lot of content out there!

He lifts a slab of rough, gray cement from a conjured table, its weight palpable in his hand.

Morpheus: “For millennia, cement has been regarded as inert structural material. Here, we challenge this long-standing perception by transforming cement into a ‘living’ energy device, ... through the development of a microbial cement supercapacitor.”

He sets it down with a resonant thud. Immediately, thin blue veins of light snake across its surface, the fluorescence of a living substrate.

Neo takes a half-step closer, eyes narrowing.

Neo: “You’re saying… walls could think?”

Morpheus circles him, slow, deliberate, his voice low and electric.

Morpheus: “Not think. Store. The very foundations of their prisons becoming batteries. Imagine—every tower in the Matrix, a living entity, feeding the machine’s hunger, while we believed them empty stone.”

The slab flares green, light coursing outward in a pulse. Neo instinctively shifts back, fists tightening.

Neo: “And you want me to believe we can turn their biopower into ours?”

Morpheus stops directly in front of him, their eyes locked. A faint smile.

Morpheus: “I don’t want you to believe it, Neo. I want you to feel it.”

Neo reaches, fingers splayed, toward the slab.

It dissolves into motes of red light, scattering into the infinite.

> At 3 days, EAM-containing samples exhibit increased overall porosity compared to the control, indicating an initial disruption in matrix densification. However, by 28 days, this effect diminishes, suggesting that hydration and subsequent microstructural stabilization mitigate the early porosity increase. Further analysis of pore size distribution (Figure 2F) shows that EAM incorporation leads to an increase in middle and large capillary mesopores, whereas coarse mesopores decrease, indicating a shift in the microstructure toward a more refined network. Despite these microstructural modifications, compressive strength measurements (Figure 2G) show that EAM incorporation does not compromise the structural integrity of cement. At 3 days, samples with higher EAM content exhibit a reduction in strength. However, by 28 days, strength recovery is observed, and EAM-containing samples exhibit a slight improvement compared to the control. This enhancement may be attributed to the formation of additional calcium carbonate, which contributes to matrix densification and mechanical reinforcement.
