I've ridden in a few of these cars. One friend had a BMW that did this at every traffic light. It was certainly noticeable and quickly became irritating. While it does offer a marginal improvement in efficiency, I think this is just another attempt to put lipstick on the pig that is the internal combustion engine. Best to just get an electric car that doesn't have to deal with an idling engine, clutch, transmission to match the poor torque curve, inefficient combustion process, Rube Goldberg emission control systems and noise.
TFA is remarkably free of tech content and specs so only can speculate. It does say the device only wakes up and broadcasts intermittently so difficult to track by it's transmissions. They should also encrypt the data so location can't be decoded. They could use something like LoRa which supports long range, low power, low bitrate data transmission and can be set up as a wide area mesh.
Flavored water is not healthy for you (diabetes, cancer, etc.) and the bottles damage the environment. Just drink tap water... or, if your tap water doesn't taste good, get a filtered pitcher (like a Brita). No excuse for all of that plastic waste.
you pay for that. Most eBay merchants accept returns. You may have to pay for shipping but you'll save unless you return a lot... (Why are you returning a lot?)
I think the fossil fuel companies are still in denial about renewables. They have only made token efforts to invest in renewables. Oil and gas companies will start to go the way of coal and nuclear companies... bankwupt!
If you'll read the Wikipedia article on lab grown meat, it requires lots of additives. Unlike plants which convert CO2 in air plus trace elements nitrogen and potassium, etc. to food, lab meat requires a "growth medium" and a collage "scaffold". Cultured meat production requires a preservative, such as sodium benzoate, to protect the growing meat from yeast and fungus. Collagen powder, xanthan gum, mannitol and cochineal could be used in different ways during the process.[66] They currently use "fetal bovine serum" (don't ask) as a growth medium.
One skeptic is Margaret Mellon of the Union of Concerned Scientists, who speculates that the energy and fossil fuel requirements of large-scale cultured meat production may be more environmentally destructive than producing food off the land.[28]
We're starting to see utilities adopting battery storage on a large scale and this only adds a small cost to renewables. Lots of people are working on lots of different solutions to energy storage (pumped hydro, mass transfer, and converting excess electricity at peak production to H2 or CH4, etc.)
You are right that in general it is better to do things more efficiently. However, this does have profound effects on where the "profit" flows. Fossil fuel companies profit from selling coal, oil, NG and they don't want those profits to go away. Electric utilities have a lot invested in fossil fuel plants and it would hurt their profits for those assets to become stranded. Also, utilities make more profit on more expensive electricity (monopoly fixed profits at cost + 10%) so they profit more by selling more expensive fossil fuel energy. When a consumer installs solar panels and starts making their own electricity, that hurts the Utility's profits.
There may be less killing involved (although lab meat seems to use an animal derived growth medium) but for those who are vegan for health reasons, it probably won't be attractive. It's still meat with all of the unhealthy animal fats and god knows what chemical, hormones, etc. they add to get it to grow. I'd leave religion out of the discussion since most religious arguments are ignorant of science.
Well... they did use the word "might" as a hedge so they are not completely wrong... just mostly wrong.
You can start with the headline: We Might Not Have Enough Materials for All the Solar Panels and Wind Turbines We Need We'll need to be mining a dozen times as many metals to meet demand for wind turbines and solar panels by 2050.
Or... According to the analysis, turbines and solar panels might be skyrocketing a bit too much. Demand for some metals like neodymium and indium could grow by more than a dozen times by 2050, and there simply might not be enough supply to power the green revolution. Or... By 2050 solar panels and wind turbines will require around 12 times as much indium as the entire world produces right now, the analysis predicts. Neodymium production will have to grow by more than seven times, and silver will have to grow by nearly three times. And this is just for renewable energy; all of these metals have other uses in other industries, meaning mining will have to ramp up very quickly.
I refuse to believe that you're stupid enough to believe what you just wrote so I'll just assume that you are obfuscating. You are surely aware that elements are not distributed evenly in the earth's crust but exist in high concentration "deposits". For millennia, man has been "mining" these deposits. I'm sure you are aware of copper, iron, aluminum, and gold "mines" where it is, indeed possible to economically mine all kinds of elements.
Here's a new "deposit" https://www.cnbc.com/2018/04/1... Researchers have found hundreds of years' worth of rare-earth materials underneath Japanese waters — enough to supply to the world on a "semi-infinite basis," according to a study published in Nature Publishing Group's Scientific Reports.

Yes. A few rich people making lots of money from fossil fuels have screwed the rest of us... and will continue until we come up with the French solution.
They fail to recognize the fact that there are constantly new sources of these elements being discovered and there are good substitutions for all of them.

You're supposed to have the drone fly up to the top of the towers so that you don't have to climb up to get the photo.

I can usually find stuff cheaper on eBay. Amazon is for suckers.

In 2008, PETA offered a $1 million prize to the first company to bring lab-grown chicken meat to consumers by 2012.[28]

I don't think that's a good assumption. God knows what chemicals, hormones, antibiotics, etc. they put into lab grown meat in order to get it to grow.
Or they could use something called a "lunchbox" and something called "reusable shopping bags" just like many people do.
I think we should let China win the contest to contaminate their land.
Well, I don't think the solution to the problem is to allow more nuclear waste.
Well... they did use the word "might" as a hedge so they are not completely wrong... just mostly wrong.

Tritium?
Not a rare earth; not a material for solar panels or wind turbines.
OTOH, the seabed is very easy to access all of these newly discovered rare earths.
Probably didn't consider this:

... but not so much about the rare earth elements market
Yes.
A few rich people making lots of money from fossil fuels have screwed the rest of us... and will continue until we come up with the French solution.
They fail to recognize the fact that there are constantly new sources of these elements being discovered and there are good substitutions for all of them.
And TFA is completely wrong.
Multiple studies have shown that 100% of energy needs can be met by renewables. We don't need fossil fuels.
