Dr. Sam Milham spent his career proving that the wiring we built our lives around is making us sick. In this interview he walks Andrew McAfee through ground current, dirty electricity and contact current, and what thirty years of measurements at one house revealed. We are streaming it once for the SYB community, then Andrew stays on camera to answer your questions.

Most people worry about the tower down the street. Dr. Milham spent thirty years pointing at something closer and far stranger. In North America the power grid sends its return current back through the earth itself, through a grounded Wye system that puts a wire from every transformer straight into the ground. That current does not politely stay there. It comes up through water pipes, through shower drains, through concrete slabs, through the rebar under your floor. Milham measured it at his own house every year for three decades and watched it climb. Europe does not have this problem, because their return current goes home on a wire.
What's Inside The Interview
Andrew McAfee recorded this conversation with Dr. Milham and brought the specifics, because Milham is the reason Andrew started measuring in the first place. No slides full of theory. Papers, meters, farms, houses and numbers.
Why North America returns its current through the earth and Europe does not, how that current gets into creeks, shower pipes and concrete slabs, and why Milham believes it is now high enough in fresh water to kill people who are only floating down a river.
Where it actually comes from. The inverter in the base of an LED bulb, the switch mode supply in your laptop, the solar array converting DC to AC. Milham walks through the single fluorescent light that measurably dropped one farm's milk production.
The measurement argument at the centre of it all. Milham and Andrew make the case that current, not voltage, is what does the harm, and why the meter Milham told Andrew to buy in 2017 changed how he assesses a house.
Andrew sat across from Dr. Milham for this interview and has spent years measuring the things they discuss. When the broadcast ends he stays on to take your questions in real time. Your shower, your slab, your well pump, the reading you cannot explain. This Q&A happens once and is not recorded.
From The Interview

Physician & Epidemiologist
Author of 'Dirty Electricity: Electrification and the Diseases of Civilization'. The first researcher to document elevated cancer rates among electrical workers, published across the New England Journal of Medicine, Lancet, Nature and the American Journal of Epidemiology. Spent his career at the Washington State Health Department and thirty years measuring the ground current at his own house.

Contact Current Researcher, Live Q&A
Recorded this interview with Dr. Milham and joins us live afterward to answer your questions. Andrew developed the contact current measurement protocol that grew out of Milham's shower research, and invented the Nuisance Current Blocker to stop current travelling on grounding conductors inside homes.
