As a UI/UX designer by trade, I explore how sustainable and smart technologies impact our lives. And I try to dive deeper into those topics to provide context. Topics like electric vehicles, solar panels, and renewable energy that is meant to transition the world off of fossil fuels. Smart home technology that can make our homes not only more convenient, but safer and more accessible. Wearable technology that can track our health and save lives. Or how technology might be invading and breaking down the walls of our privacy. So in short... Exploring how technology impacts our lives.Matthew Ferrell
  • The Problem With Home Batteries (It's Not the Battery)
    Jun 23 2026

    How a Plug-In Home Battery Finally Works for Renters and Apartments. Go to https://surfshark.com/undecided or use code UNDECIDED at checkout to get 4 extra months of Surfshark VPN! For most people right now, home batteries kind of suck. You spend ten to fifteen thousand dollars, wait on permits, and pay an electrician, and that is only if you own a house that can take one. A new plug-in home battery changes the math. It plugs into a standard wall outlet, needs no electrician, and the units link into a mesh home battery network that moves with you. I put three of them in my own house and ran the numbers. So can a battery like this really deliver backup power for renters and apartments? Or is this just a smaller box with the same old limits?Video script and citations:https://undecided.tech/the-problem-with-home-batteries-its-not-the-batteryWatch This 10¢ Battery Turns Seawater Into Freshwater https://youtu.be/j-C7A8kmJuQ?list=PLnTSM-ORSgi7uzySCXq8VXhodHB5B5OiQGet my achieve energy security with solar guide:https://undecided.link/solar-guideFollow-up podcast:Video version - https://www.youtube.com/channel/UC4-aWB84Bupf5hxGqrwYqLAAudio version - https://undecided.link/stilltbd-podcastJoin the Undecided Discord server:https://undecided.link/discord👋 Support Undecided on Patreon!https://undecided.link/patreonVisit my Energysage Portal (US):Research solar panels, heat pumps, and more to get quotes for free!https://undecided.link/energysageFor a curated solar buying experience (Canada)EnergyPal's free personalized quotes:https://undecided.link/energypal👉 Follow MeMastodonhttps://mastodon.social/@mattferrellBlueskyhttps://bsky.app/profile/mattferrell.bsky.socialInstagramhttps://www.instagram.com/undecidedtechWebsitehttps://undecided.techSome music provided by Epidemic Soundhttps://undecided.link/epidemicI may earn a small commission for my endorsement or recommendation to products or services linked above, but I wouldn't put them here if I didn't like them.

  • Why This Battery Is The Swiss Army Knife of Renewable Energy
    Jun 16 2026

    How a Saltwater Battery Desalinates Seawater and Captures Carbon. Go to https://ground.news/undecided for an innovative way to stay fully informed on tech, energy, the climate and more. Save 40% on the Ground News unlimited access Vantage plan with my link. Drop your phone in the ocean and you learn fast that seawater destroys batteries. So a seawater battery that actually runs on the stuff sounds backwards. Yet researchers in Korea have spent over a decade building one. This single system stores energy, turns seawater into drinking water, and pulls carbon dioxide from the air. One device doing the work of a battery, a desalination plant, and a carbon capture rig. So is this a real Swiss Army knife for our energy and freshwater crises? Or is a 3-in-1 promise just too good to be worth its salt?

  • The $Billions We’re Burying in Plain Sight
    Jun 2 2026

    The $Billions We’re Burying in Plain Sight. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided There's $67 billion in critical minerals sitting in your trash can right now. Old laptops, dead drills, that printer you keep meaning to throw out. The piles of waste outside old mines hold even more. By some estimates, between e-waste recycling and mine tailings, America already has nearly all the rare earth elements it needs, without digging a single new hole. One New Hampshire startup, Phoenix Tailings, is already turning toxic mine waste into wind turbine magnets using a furnace as hot as lava. Every few years someone promises a clean fix to the critical minerals problem, and every few years we keep buying them from China. So is remining actually the answer? Or is it just another shiny promise headed for the dustbin?
