I had a chance to sit down and chat with Mike Donaldson, the Vice President, Fusion Island Engineering at General Fusion. It’s an interesting conversation about not only General Fusion’s technology, but the fusion industry at large. Hope you enjoy.

Matt and Sean talk about zinc batteries and why old tech doesn’t always stay old.

Matt and Sean talk about where Undecided is headed, and how it’s going to get there.

Matt and Sean talk about what you get when you mix solar and calm water. There’s a lot of similarities between solar panels over water and solar panels over crops (agrivoltaics). There’s also a lot we can learn about solar from countries like India.

On today’s episode of Still To Be Determined we’re turning our beer cans into batteries … well … we’re talking about aluminum ion batteries and how they might be the successor to the lithium ion battery.

Matt and Sean discuss start-ups’ fusion energy plans, their timetable, and their potential. We also talk to Helion Energy’s CEO, David Kirtley about their technology.

Matt and Sean discuss Unity Homes’ approach to sustainable homebuilding (including Matt’s home!).

Matt and Sean discuss large-scale passive buildings and the different technologies available today to make it happen. Everything from regenerative braking on elevators, to solar panels plus battery energy storage, to ERVs and air tight construction.

Matt and Sean discuss nanotechnology advancements driving battery breakthroughs from companies like EnergyX. Their metal organic frameworks are revolutionizing lithium mining, and potentially lithium batteries as well.

Matt and Sean discuss supersonic air travel and Matt’s real feelings about biofuels and Boom’s prospects.
