Using cars for backup grid energy probably doesn't work

Pumping water into a reservoir is great for storage

In the world of electric cars, some people talk about an idea called "vehicle to grid" or V2G. Renewable energy's biggest challenge is storage -- wind and solar only come at certain times of the day, but we need electricity all day. The V2G hope is to use all the batteries in electric cars as a means of grid storage.

Sleeper cars and the unexpected efficiency of solo transport

My article last week on Sleeper cars generated lots of interest, and Volvo's concept car generated lots of press too. Some of it was quite negative, including a article provocatively calling them the dystopian future we must prevent. I thought I would revisit some of the things about such vehicles that run quite counter to the intuitions of those used to 20th century transportation and transit.

New Canon mirrorless camera looks like it doesn't go far enough

Canon has finally released a higher-end, full frame mirrorless camera. Nikon also released theirs a few weeks ago. Canon had seriously botched their entry into APS-C (smaller sensor) mirrorless with the M series. Nikon did a better job. Sony took ownership of the full-frame mirrorless space causing many, including myself to switch, even though their cameras were far from perfect.

Waymo's left turns frustrate other drivers

This week's hot story was again from Amir at The Information and there is even more detail in the author's Twitter thread.

The short summary: Amir was able to find a fair number of Waymo's neighbours in Chandler, Arizona who are getting frustrated by the over-cautious drive patterns of the Waymo vans. Several used the words, "I hate them."

Cars will go to the chargers, you don't need to bring the chargers to the cars

This is where your car charges, not at your house

Many of us believe that there's a natural fit between electric drive trains and robocars. It's not required -- you can certainly make robocars driven by gasoline, natural gas, hydrogen or anything else.

Electric has several advantages:

Can travel books enter the 21st century?

When you travel, a whole ton of online resources are available, but there is still great value in the classic guidebook that you pay money for. Free tourist information (particularly from tourist boards) is not acting in your interest. Some of the ad or booking supported travel sites do give independent information (or aggregated user information) but they have their biases as well, and are also full of review-spam.

Uber might sell its robocar division, Nuro opens first delivery pilot in Scottsdale

Uber might sell self-drive division

The newsletter The Information reports Uber's investors are pushing Uber to sell its self-drive division to some other large player. The division has, of course, been nothing but trouble for Uber, and as I have noted several times, Uber is one of the few large players in this space that doesn't have to build their own tech. They have the #1 brand in selling rides, and selling rides is what the robotaxi business is all about.

"Grand Science Fiction" -- a proposed description of the best in SF

There have been many efforts (none much of a success) to define Science Fiction and the related genres of fantasy, alternate history and speculative fiction. It might be more useful to examine why the genre exists, and why people come to it, and thus what may (to some) define greatness within it.
