Quick Announcement

A smart panel adds a few thousand dollars to an already expensive project, so Matt asks the awkward question straight out. Reynolds Holmes, VP of Product at SPAN, answers with a test: will you add an EV, a battery, a heat pump, or a new AC in the next ten years? If yes, he argues the future proofing pays for itself, and he explains why judging the decision on twelve months of old utility bills is backwards math. Matt also pushes on privacy, local API access, and what happens to your hardware if SPAN ever disappears.

310: Is a Smart Panel Worth It? With Reynolds Holmes

Perovskite solar has promised a revolution for over a decade, so is it finally real? Matt and Sean talk with Joel Jean, co-founder and CEO of Swift Solar, the US startup spun out of MIT and Stanford. Joel explains how stacking a perovskite film on top of silicon lifts a solar cell's efficiency ceiling from 30 percent to about 45 percent. He also breaks down the three "tooth fairies" every new solar technology has to solve: performance, lifetime, and cost. So is perovskite tandem solar finally ready for your roof? Or is 25 year durability still one miracle away?

308: Smart Homes with Paulus Schoutsen

The inventor of the Super Soaker, Dr. Lonnie Johnson, joins Matt to talk about his most ambitious project yet: the JTEC, a heat engine with no moving parts that converts low-grade waste heat straight into electricity. They get into how it actually works, why Johnson thinks it could run far more efficiently than what we use today, and the long road from a 2003 idea to the first commercial unit. Plus how a billion-dollar water gun quietly funded a quarter-century of clean-energy research.

307: From Super Soakers to Heat Engines with Dr. Lonnie Johnson

Matt sat down with Jorge Diaz Schneider, CEO of Ion Storage Systems, to talk about their anode-less, ceramic-based solid-state battery that doesn't swell or need pressure to work. We get into why they're chasing consumer electronics instead of EVs, the new continuous manufacturing line they just fired up, and why so many solid-state startups have over-promised and flamed out. It's an honest look at where this technology really stands in 2026 … and where it's headed.
