Alternative Energy Sources discussion

Totally agree. I have been following fusion for 15 years or more. It seems to be finally getting to the point of actually delivering on the promise. I don't think we are ready for the changes that fusion will bring. The global financial structure is based on oil. When that market is dramatically reduced there is going to be many unintended consequences. At the same time there are so many positives. Imagine being able to create unlimited fresh water via osmosis, and being able to pump that water anywhere. Terraforming the Sahara desert to a grassy savanna that absorbs tons of CO2 is just one possibility.

To be really fair, you should gather the statistics of ICE vehicle fires as compared to EV vehicle fires. Yes, some EVs have burned down houses, but many more Lawnmower and car fires have burned down houses….
Bugs are known to happen in most any kind of technology - particularly in their relative infancy..
There's some important differences about EV fires v. ICE. EV fires can't be put out with fact, that's likely to make it worse. Lithium reacts with water extremely aggressively. Other containment methods are not very effective as the "fire" is really a self sustaining chemical reaction....called "thermal run away" in battery speak. For these reasons, EV fires represent a much greater fire hazard than an ICE fire.

Also, an ICE fire is essentially a fire of liquid fuel combined with other flammable materials. The fuel is not "atomized" at that point and is less flammable. An EV fire is a rapid (almost instantaneous) discharge of the battery causing intense heat and flame which spreads to the rest of the battery quickly. It is more like burning atomized liquid fuel. The battery in that E-bike that burned up is tiny compared to an EV battery

Currently, the best EV batteries are only about 1/3 the energy density of liquid fuels (gravimetric or volumetric). As these batteries continue to become more and more energy dense, then the hazard just becomes proportionally greater. Yikes.

The battery industry has a long way to go in improving the safety of EV batteries as energy densities continue to increase.
