If we could tap into even a tiny fraction of this geothermal energy, it could power the world for millennia with clean energy on demand day and night and no matter the weather or the season. The only problem is that in most places on earth, geothermal power is locked away deep below the surface – too deep to drill, except in those lucky locations where underground reservoirs of steam and hot water exist close to the surface. But new geothermal technologies could make this energy accessible almost anywhere. In this video we’re going to find out how exactly how these technologies are digging deeper and hotter and hoping to bring geothermal from niche to mainstream. And we'll take a look at leading goethermal startups Quaise, Fervo and Eavor to find out their progress and future plans.

Are we running out of critical minerals for EVs? Not really. Reserves are sufficient; the challenge is scaling up mining and refining quickly. Alternative chemistries like LFP and sodium-ion batteries, and rare-earth-free motors, offer flexibility if needed. https://youtu.be/C0ZtX5d-WE0
EV Myths You Thought Were Facts
Electric vehicles are taking the world by storm, sparking conversations and controversies alike. Are they the green champions of the road or hidden culprits of environmental harm? Can they truly replace the roar of petrol engines without missing a beat? And is our infrastructure ready to support this electric revolution, or will it buckle under the pressure? In this video, we're plugging into the heart of these debates. We'll explore what happens when innovation meets the open road, and whether the journey towards electric mobility is as smooth as the ride in an EV itself. Join me as we navigate through the electric landscape, separating fact from fiction with solid evidence and expert insights. It's time to discover the real story behind electric vehicles.

Is hydrogen hyped only because it's simple to explain? Just burn hydrogen instead of fossil fuels, so simple! H2 may be the easy answer to "what can we burn instead of fossil fuels?" but it's the right answer to the wrong question according to Paul Martin. https://youtube.com/shorts/my2vo1J5pOU
Dunkelflaute - no wind, no sun for weeks - isn't an Australian problem. 42 years of weather data show widespread dips last hours or a day, never weeks. Winter monthly output has never been lower than 70% of average. Long duration energy storage... https://youtube.com/shorts/kiKCnACikpY?feature=share
Floating wind is still small, just 200 MW installed in 16 years. But over 200 GW is in the pipeline. Norway leads, the UK has big plans, and Japan & South Korea see it as key to their energy transitions. Even Australia & China are diving in. Ho... https://youtube.com/shorts/OFofvtPq_mI?feature=share
So far, all floating wind farms have used standard offshore turbines on floating substructures. But new designs are emerging: vertical axis turbines for lower centers of gravity, multirotor designs to avoid massive rotors, and innovations in to... https://youtube.com/shorts/IzDAiAJ3mYE?feature=share
Can nuclear play nicely with renewables? Its steady output doesn't complement fluctuating demand from wind/solar, needing hydro or batteries to balance. Countries like Sweden manage it with hydro, but no grids have a lot of nuclear and a lot of... https://youtube.com/shorts/0lixZkq62No?feature=share
Nuclear for Australia? Too slow, too expensive & it doesn't fit with renewables. By 2033 90% of our electricity could come from renewables. Why solve problems we don't have, like needing "baseload"? Rooftop solar has killed baseload in Australia. https://www.youtube.com/shorts/WN5siWZHhFg
Chinese wind turbines are pushing the limits with plans for 30 MW models, nearly double today's largest. Bigger turbines mean fewer installations and more power from higher winds. But engineering limits mean there's a trade-off. At some point, size doesn't a... https://youtube.com/shorts/NYagH0rQBt8
How do massive wind turbines stay afloat? Designs like Spar buoys, tension leg platforms, and semi-submersibles keep them stable in deep waters and rough seas. There's some amazing engineering behind this, but is it practical? https://youtube.com/shorts/C2rGu6PDGmg?feature=share
A 900 MW water battery in the Swiss Alps, built for €2B over 14 years, is operational. It uses two reservoirs at different elevations to store energy by pumping water uphill and generate power as it flows down. It's 20 GWh, enough to power 400,000 EVs. https://youtube.com/shorts/T2ctLzuG-ig
If every house in Australia turned on a toaster simultaneously, it'd add nearly half of the grid's average load, causing it to crash. Yet, no one worried about the grid when electric toasters became widespread. So why do we still think that EVs will crash the grid? https://youtu.be/qUDtmom5-vg
Floating offshore wind is expensive, but it unlocks high-wind-speed sites far offshore and in deep waters where fixed-bottom turbines can't go. Plus, no one has to see or hear them. Could floating wind be the answer for untapped energy potential? https://youtube.com/shorts/ElPp6Ri-yko?feature=share
Forget hours of charging - new 500kW wireless tech can fully power up a long-haul electric truck in just 15 minutes! 🤯 That's like getting your home's energy for a whole day in just 3.6 minutes, without any cables! https://youtube.com/shorts/RTM8vmRs2mY
Kite power systems generate electricity by unwinding a tether as the kite ascends, converting mechanical energy to electrical power. Once fully extended, the kite is reeled in using minimal energy, repeating the cycle to maintain continuous operation. https://youtube.com/shorts/zk3LlnlT0jU
The world's largest sand battery is coming to Finland. With 100 MWh capacity, it can store excess solar/wind energy and cut district heating emissions by 70%. Heat stays at 500°C for months, replacing oil & woodchips. https://youtube.com/shorts/KkiJOT9F8B8
Ditch the charging cable! 🔌 Is wireless charging for EVs about to go mainstream? 🔋 See how this tech works like an induction stove to power up your ride. 🔌🚗 https://youtube.com/shorts/3eQVnwzeK5M
Floating wind power has come a long way, from an 80 kW prototype in 2007 to Hywind Tampen in 2023, the world's largest floating wind farm powering offshore oil platforms. How much further can this technology go? https://youtube.com/shorts/s1WxCiWN9gQ?feature=share
I might have to write off my Peugeot EV that has 2,500km on the odometer. It just needs a firmware update and absolutely no one thinks they can do it as it was originally sold in Japan (now in Australia). Does anyone have any suggestions? Or know who will buy a lightly used 50kWh battery at least 😭😭
It's been a bad week for me on social media, I've had two men chasing me across platforms & searching out alternative contact methods to voice their EXTREME disappointment that my professional opinions differ from theirs. Seemed like a good time for my first post, are people more respectful here?
