Today's hot episode is all about the heat.

As the first cold day is approaching, how can you get the most out of any planned heat pump or one you have in place?

Why does the planning of the installation matter? Why should you look at the settings?

Heat pumps are not the only story in town when it comes to electric heating but getting it right can make it pay for itself.

On Saturday the numbers behind this podcast will be published on Driving off the Grid - heat pump section.

What happens when you drive an early-generation electric vehicle for over a decade, rack up thousands of miles, and bypass modern tech nannies entirely?

In this episode, we’re cutting through the second-hand EV panic and looking at the reality of long-term electric ownership. From keeping maintenance bills under £200 per annum and proving that replacing early battery packs is not a massive cost when the time comes, to why we should celebrate "dumb" cars that don't aggressively yank your steering wheel on country lanes, this episode is about the real-world economics of keeping a classic EV on the road.

Forget the hype, the anxiety, and the endless alerts. Let’s talk about true automotive longevity and driving joy. See why I 💚 our Leaf.

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.
