Interesting. What system were running the cards on?

The fans enable cornering at basically double the lateral g force of any other production car.

They also enable the insane launch traction needed for the non thrust 0-60.

It's the key to the cars performance.

Either incompetent or on purpose. A nutless monkey could have done better extrusion detection.

Solid state batteries come in several flavours. Most of them don't stop dendrites.

The flavour you want is polymer, single ion conducting solid state with an ion transport activation energy below 10kJ/mol at room temperature and no phase transitions from -40C to 80C.

That is the holy grail of SS batteries.

You wake up. The room is spinning very gently round your head. Or at least it would be if you could see it which you can't. It is pitch black.

The advance would come from building systems that can scavenge waste heat from multiple sources instead of just exchanging with outside air.

The model Y introduced the "octovalve" which regulates flow in 13 different configurations to bring the highest quality heat to the cars heat pump.

In a house this might be something like extracting heat from grey water, or even cold tap water, ports for a solar heated loop, fresh air exchange etc.

System integration enabling efficient use of heat transfer is the opportunity

The Tesla heat pump also introduced high volume low cost manufacturing processes like semisolid aluminum casting and friction stir welding. That promise to lower costs.

Another thing that is potentially achievable with a low cost integrated approach is staged heat pumps for hot water tanks.

The possibilities are endless really, at the limit these ideas lead to integrated neighborhood scale heat networks tied to rooftop solar that can replicate district heating strategies.

Lots to be done.

Dude, you were messing with the canbus network. If FSD got into an accident because of some communication failure it could potentially cost the company billions of dollars and get people killed. I would do the same thing.

I have HW3 in Canada and I use FSD everyday. It regularly drives me for my entire commute with no interventions.

The fact that FSD in Europe has been massively delayed is mostly the fault of regulators.

Sad but true.

In this case the utility executives work for public utilities. So capitalism isn't to blame. It's about the incentives of the incumbent energy providers.

It is already cheaper to build the distributed energy solution you describe but making that change would require a massive restructuring of electricity and natural gas utilities. Such a restructuring would revalue the debt that backs the existing infrastructure. This would be a great thing for the average person but not for the people currently in charge of regulating what types of systems are allowed.

Costs of distributed energy may drop so low in the next 5-10 years that it will no longer be possible to keep things from moving to a micro grid network.

Totally agree that regulations and government interference are the reasons we don't have cheap solar panels.

Those regulations and that interference result from the fact that in a distributed world the current utility bond value drops to zero. Utilities will not build infrastructure that makes their existing infrastructure lose value.

I recently negotiated with a government owned utility on a large solar project. They were 100% against it until I demonstrated that the project would never feed back to the grid and wouldn't reduce the amount of power we currently buy from them. Zero interest in distributed solutions on their side. They are focused on giant transmission line projects and hydro.

I recently specced a 500kW project. Quote was $CA1.67/Watt. But I'm pretty sure they would have bumped that up a lot higher later in the process if we hadn't stopped due to permitting hurdles.

I have some experience with distributed energy generation and have met with senior utility executives many times while trying to implement some grant supported projects through my work.

It turns out that a big problem is that whenever we install local generation it costs utilities a ton of money. They bundle the cost of grid maintenance into their per kWh charges. These costs, which include debt service, maintenance, upgrades etc amount to 5-7 cents/kWh. Whenever you generate your own energy you cost the utility 5-7cents/kWh that they have to pay regardless of your usage.

This business model, which has bundled grid maintenance into usage costs means that utilities put up huge roadblocks for distributed generation. They say they love it, but they actually hate it. Utility executives have looked me in the eye and said as much.

It gets worse though, because energy infrastructure is backed by trillions in utility bonds. These "low risk" debt instruments are owned by national and private pension funds of mind boggling size. In order to bring about a distributed energy future the grid (and low pressure nat gas infrastructure) must be reorganized in a manner that is likely to make those bonds worthless. These background factors are definitely in play when you see these bait and switch enthusiastic green energy programs that turn out to be a regulatory quagmire when you dig into them. Public utilities and pension funds hate green energy, they are a major factor in west's pathetic performance when it comes to solar adoption vs China.

Rooftop solar in Australia is ~60cents per Watt installed.

The viability of direct to cell connectivity at scale is unproven. This is actually the core value of SpaceX in the next 3-5 years.

The other core value generation product will be financial transactions. It is unproven whether X money will be adopted for friction free transactions across national boundaries and whether the company can compete in the financial services sector.
