“Autonomous”. You keep using that word.

You keep using that word. I do not think it means what you think it means.

ARD-Reporter does not understand the term “autonomous”.

Thanks for the pointer. Cars need 5G [networking] because of latency. Short reaction time for braking.


Nope. That’s not how it works. (Twitter thread starts at

Generally: Cars cannot trust externally supplied data (“cloud data”) for critical driving safety things. The cloud may be unavailable, the link into the cloud may be unavailable or the information fed into the cloud may be wrong, maliciously wrong or outdated. So all that external environment information is as trustworthy as the spoken traffic report after the radio news, it’s a machine readable, more detailed version of exactly that.

Ground truth from the sensors always has to be able to supercede that, and the car must always be able to drive safely with ground truth from sensors alone.


Can I drive an electric car?

EValuation is an app on the Play Store.

It records your daily driving over some time creating a usage profile. The app then lists which electric cars would fit your profile.

The app costs 1.49 EUR.

It does not correlate with public transport, but that’s easily done manually with the profiles created.

Predicting the Jump to Electromobility

An article in The Guardian states:

Solar power and clean cars are ‘gamechangers’ consistently underestimated by big energy, says Imperial College and Carbon Tracker report. […]

Big energy companies are seriously underestimating the low-carbon transition by sticking to their “business as usual” scenarios which expect continued growth of fossil fuels, and could see their assets “stranded”, the study claims.

They are seeing a worldwide halt in growth in demand for oil and coal by 2020.


Solar plus Storage in Australia

In the 2016 South Australia Blackout, a storm lead to a cascading failure, with in turn left 1/6 of the continent without electricity. Fortunately, this is not a densely populated area even for australian circumstances, so it affected some 1.5 mio people (out of 20 mio total for all of Australia) – still quite a lot of people.

The news of a 73-year-old Tesla Powerwall owner powering through this outage without even noticing made the headlines in the aftermath, and in consequence demand for PV + Battery combination surged. In total, more than 50GWh have been installed in 2016 alone, and demand is climbing.

The Energiewende Dashboard

LichtBlick and the WWF have a new, common website, (Website in German, literally “acclerating the Energy turnaround”).

The dashboard shows the currently installed capacity in Renewables compared to Fossil energy sources (100GW vs. 90GW), the current energy mix and the CO2 output of Germany.

The site is a good overview of what works, and what needs more work done. For example, while electricity in Germany is on track towards renewables, electrification of mobility is lagging.
