Sunbeams, Slide Rules, and Staying Power

As the autumn equinox arrives, this week’s episode takes a reflective yet practical look at the lifecycle of solar technology—tracing our relationship with ambient energy all the way from childhood classroom calculators to modern domestic microgrids.

• From Retro Tech to Rooftop Arrays: We take a nostalgic walk down memory lane, looking at early solar-powered essentials like the classic Texas Instruments calculators (the TI-1766 and TI-34) and exploring how those early encounters with ambient light sparked a lifelong appreciation for self-sustaining power. My family has been harnessing solar power for a while.

• The Myth of Planned Obsescence: Moving past the modern cycle of constant upgrades, this episode challenges the throwaway culture surrounding electronics and energy hardware. We look at why true sustainability is rooted in rugged longevity, proper maintenance, and respecting the gear we already own.

• Everyday Ambient Efficiency: Connecting vintage low-power tech to modern setups—including solar-driven keyboards and a 4 kWp domestic rooftop array—we discuss how small design choices accumulate into genuine resource independence.

Tune in as we explore how looking backward at enduring design can help us build a more mindful, resilient, and off-grid future.
