This is great news.

Luigi Colani is the designer. If you have time Google him and follow that rabbit hole as far as you like. Lots of good rocket inspiration on that journey.

Nice looking bus. I wonder how tough it is to drive an articulated vehicle?

Click to expand...

As part of my technical work with our public transport system I was put through the training and given a bus license. The artic buses, if designed correctly, drive identical to a single bus. The rear section steers to track the front.

The first thing to watch for is that when reversing it backs like a trailer with a short drawbar, and will also lock the brakes if you get to 45 degrees bend. The second thing is that the tail can kick wide if not driven in a particular way sometimes.

Easy to drive really.
 
listening to a clip of Elon Musk explaining if you take 125 square miles of unused desert in Nevada and covered it in solar panels that it would power the entire USA, I've heard that several times before.

In practice, what Tesla is doing is installing large battery packs to eliminate peaks in the grids. People can charge them however they want.

"A new survey by consumer research specialist J.D. Power finds that US auto shoppers are more likely than ever to consider buying a pure EV, mostly thanks to the growing selection of models."

It's amazing how much research is going into making better batteries!

Depends on your point of view. My kids toy cars have had graphene ''nano'' batteries for at least 5 years now.

I'll take whatever we can get, but flashlights are still just flashlights. Not exactly breakthroughs as they evolve.

It's as if you think this thread has -something- to do with flashlight batteries.

Maybe you missed it, or maybe you want to play with me, but there's a new electric boating series. Not a flashlight. Not just just bigger toy. Not just a boat big enough to carry a person. Not just a racer. A series.

What they carry is not a lead acid battery like any of the 1B cars on the road today rely on.

We got electric toy boats to. Cool, but not new.

KTM still appears to have an electric dirtbike. Being that dirtbikes are extremely maintenance intensive, it's very cool:

I've been pressuring them to release a street legal version, Ala EXC500 style. You're not going to clear 100' jumps like the gas bikes with one, but looks fine for woods action.



Too bad that it sounds like a 1/8th scale Ebuggy.

And a table I cleaned up for my personal enjoyment. Graph below from same source.

Progress and breakthroughs are found by looking up and to the right.

@KC3KNM , are they using the VTOL for this craft yet? The video pretty much showed it taking off & landing like a regular plane.

CTOL testing on this airframe and hover testing on a second airframe right now. Getting hours on both airframes before transition testing, but it’s not too far out. With the FAA guidelines being a moving target at the moment, the road to certification on an Alia in airplane mode is a lot shorter than the VTOL approach.

Alia is a sweet looking craft! When a VTOL video is available let us know.

I had a Hyundai Accent when I was a poor student and needed the cheapest car available. It never failed me so much later, when Hyundai made the Ioniq, I got one because the reviews I found said it was better than a Prius in many ways. Now I don't know if I'm biased because I've had a couple of Hyundais but the new Ioniq 6 looks really nice to me. The profile suggests it's very aerodynamic.

And in fact:

"And it doesn't just look like a wind cheater: Every surface of the Ioniq 6 has been honed in the wind tunnel to help deliver a claimed drag coefficient of 0.21, which would make the Ioniq 6 as slippery as a Tesla Model 3."

Dissasembling what is arguably the most advanced EV available today: a Texas-built Model Y. It includes the long-anticipated 4680 battery cells (46 mm diameter by 80 mm tall), which have a high energy density, are quick to produce, and are structural. Everything here screams efficiency.

Honda is releasing 50 EV cars for the whole of Europe, "with prices in the UK starting from £38,120".

https://www.honda.co.uk/cars/new/honda-e/honda-e-limited-edition.html
Specs not anything to faint about, but at least Honda finally has something, and it's fine for city driving. I think it goes to show just how difficult it is for car manufacturers to find or make enough batteries to build an affordable EV for everyone. Still hoping battery production in all countries increases by a lot.

It’s kind of an interesting statistic if accurate. That’s a butt-ton of solar panels, but in the grand scheme of things, not a lot of land compared to all the land available. In reality, it would probably be 125 locations of 1 square mile each, or many more even smaller sites adding up to 125 square miles.

EDIT: After posting, I thought that figure of 125 square miles cannot possibly be right. It seemed absurdly small. I looked it up, and it’s closer to 20,000 square miles, so maybe a square 125 miles on a side, not 125 square miles.
