utter nonsense - but shows how thoroughly uninformed people can so easily be misled to draw ruinously incorrect conclusions...

why is it that all these renewable energy prosthelytizers can never articulate a coherent solution/end game? He is right, the number of pv cells needed to generate the required electrical energy is irrelevant - that is only a part - and possibly only a small part - of the problem. He gets us to all the required PV panels, but glosses over the question of storage, hydrogen, how hydrogen can be stored, air transport, etc. etc. etc. What's the point of a video like this? Waste of time and electrons...

Idiot. He completely lost any credibility with me with the statement that "you can only solve an economic problem with economics". Really? I can think of a lot of economic problems that have been solved with chemistry, physics, and engineering - because the underlying problem is one of chemistry, physics, or engineering. When the economics dictates that it's worth investing in the chemistry, physics, or engineering to solve a problem, then that work will be done - either by private enterprise or by government sponsored research.

The problem could also be greatly solved by the using public - if they properly sorted their plastic recylcables, then there would be much less of the waste plastic - but they are too Fing lazy to do that. I would respond to the diatribe against the plastics industry with an old Pogo quote: "we have met the enemy, and he is US..."

this guy is looking to have his very own superfund site. have to wonder how he manages to "clean up" and what he does with the waste products...

At the time this song was most popular, there was much discussion of the meaning of refrain - parsley, sage, rosemary, and thyme. One interpretation was that it was a nonsense phrase substituting for "sober and grave, grows merry with time" - as applied to the loss of a lover (or a lovers') affection (s/he'll get over it...) but contrasted with the clearly mournful tone of the song suggesting that this lover didn't....

completely bogus demonstration: if you look carefully, you will see that the water in the basin for the first demonstration was completely still - and drained straight down. But for the north and south demonstrations, she poured the water into the basin at one side of the basin - setting up circulation in the basin - and immediately pulled the plug. What she was demonstrating was conservation of angular momentum, not the coriolis effect.

An extraordinarily simplistic and misleading discussion of tax laws. They very cleverly point out the disparity between the benefits of tax deductions between those with annual incomes over $400K and those below, but neglect to mention what fraction of the total tax payments each group provides.

Also suffers from the implied perspective that all the money actually belongs to the government and it's the government's right and duty to determine how much of it you get to have...

Fascinating... the attacks and parries are pretty sophisticated...

Unfortunately, everyone on this is wrong - I don't agree with transmorpher so much, but if we don't get population growth under control, all the green energy in the world won't be enough. Which is why the Pope pontificating on planetary stewardship is nothing short of obscene. When the Catholic Church starts making birth control a mandatory practice for good Catholics, then I'll start believing his advice on global stewardship is sincere.

Idiot narrator/narration. The gases discharged there are dominantly sulfur dioxide - not hydrogen sulfide. There is a difference - and each has a different physiologic impact on human health. Clearly these people are being impacted by the sulfur dioxide...
These so-called science videos should really try harder to get their science correct.

Understand that there is a difference between phreatic and phreato-magmatic eruptions... Wohletz and Heiken are referring to well blow-outs that can occur when the well casing or cement bond between the casing and the formation fails (it's also true that, if the well is cemented in poorly consolidated formation, the formation around the cemented well can fail and allow steam to rise to the surface). Those events could, arguably, be referred to as phreatic eruptions. But most geothermal wells are not drilled into molten magma - as I noted in my original comment, that has occurred rarely but, when it has, it has not triggered a phreato-magmatic eruption.

I'm sorry, this is silly science. Maybe I'm jaded, but if you want to study the reaction of lava going into water, this is happening every day (now) at Kilauea. But the ending piece of alarmism over phreatomagmatic explosions being triggered by water injected into magma is nonsense - researchers and private sector drillers have drilled into magma in Hawaii and in Iceland with no adverse affect at the surface.

These guys make a start at assessing the energy/carbon cost, but stop well short of completing the job. What is the life-cycle carbon cost of PV cells used to produce the electrons; what is the life-cycle cost of the storage of electrons prior to going into the EV, etc. Only then can you make an honest carbon balance sheet.

Thank you... You noted the number of recalls of organic foods; would have been even more valuable with a comparison of proportional illnesses/deaths resulting from organic versus conventionally produced foods.
