> An estimated 4-6 billion male chicks are slaughtered globally every year because they serve no economic purpose. Some are suffocated, others are fed alive into grinding or shredding machines to be processed into reptile food.

“If you can determine the sex of a hatching egg you can entirely dispense with the culling of live male chicks,” said Seleggt managing director Dr Ludger Breloh, who spearheaded the four-year programme by German supermarket Rewe Group to make its own-brand eggs more sustainable.

Breloh said his first breakthrough came when he approached scientists at the University of Leipzig where Prof Almuth Einspanier had developed a chemical marker – similar to a pregnancy test – that could detect a hormone present in high quantities in female eggs. Mixed with fluid from fertilised eggs at nine days, the marker changes blue for a male and white for a female, with a 98.5% accuracy rate.

A laser beam burns a 0.3mm-wide hole in the shell. Then, air pressure is applied to the shell exterior, pushing a drop of fluid out of the hole. The process takes one second per egg and enables fluid to be collected from eggs without touching them.

“It worked absolutely faultlessly,” said Breloh of the test phase. “Today, female hens are laying eggs in farms in Germany that have been bred without killing any male chicks.”

This number isn't from the activist group though, it's from the corporate public relations team trying to bump their failed program.

Heaps of dead test subjects, but they cherrypick one group that had an abnormally high survival rate [perhaps the control subjects; installation but no functionality?]

Fulfilling contractional obligations shouldn't even be an "event". It shouldn't come a year later than promised.

I'd imagine if the trucks aren't delivered today, Musk is going to jail for fraud.

Other electric semi companies have delivered dozens of trucks without issue or fuss; what's holding up Tesla?

> Rather than getting stuck into real estate, building traditional fuel stations and setting up H2 supply chains, Hyperion has decided to build mobile fuel stops that can be towed wherever you want, and left there for however long makes sense.

They won't need to buy land or sign long contracts; if they're not getting used, they can be moved somewhere else. It'll be interesting to see how they communicate these moves to customers, assuming they've begun to rely on a given station.

> These will replace some older battery electric plug-in buses that are also zero-emission. But some will replace buses that run on Compressed Natural Gas (CNG), a fuel much cleaner than diesel but one that still produces greenhouse gases (GHGs) that contribute to climate change.

> One hydrogen bus will eliminate the 3,655 grams of carbon dioxide emitted per mile by a CNG bus, said Roland Cordero, director of maintenance and diesel technology for Foothill Transit.

Just put a big piece of tape over the "Sport" button - problem solved boss

Honestly, it doesn't even do much; just makes it "feel" sporty

Fun times is turning traction control off and sport button on

It's like a 200 hp motor, its zippy off the line but doesn't hold its own later on... and the governor is around 93 mph or so

Alright, let's do better math;

> According to a pizza delivery driver from Ohio, drivers can average “around 80–120 miles on your car per night

Let's estimate 100 miles per night;

Milage is $0.625 / mile; personal vehicle ownership assumes only 260 working days whereas fleet car is operating 360

Cost of milage for personal car [260 days]: $16,250

Cost of milage for personal car [360 days]: $22,500

Cost of milage for personal car [1800 days]: ~$112,500 [we assume this number is not accurate given that change in milage]

Each night, Dominos fleet major expense is electricity, which at residential rates of $0.10 / kwh, that'd be ~$2.85 / night / car [3.5 kw / mile, 100 miles / night]

Battery durability should allow for more than 80% after 5 years, 180,000 miles easily

So, looking at 5 year total;

Total cost of Bolt [1800 days]:

Electricity: $5130

Tires: $2400

Car: $27,000

Total: $34,530

I feel like I should just make this an algebraic expression so I can wolframalpha yall a chart when it makes sense for Dominos to buy their own fleet vs paying milage

Regen braking with lots of in city driving is perfect...

Not to mention when they're idling / waiting for delivery, they can be plugged in

No point in even turning them off because they only pull about 1-2 kw idling in winter

65 kwh battery, 15 min wait for the next delivery at around 50 kw means 20% charge or around a 50 mile range
