Seems like precious little hydro generation. Due to States being more arid? Much higher hydro percentage in Canada I would think, but then a fraction of the population, and we're pretty soggy.
I wonder what Edward Tufte would think of that? The Work of Edward Tufte and Graphics Press Posted via the PriusChat mobile app.
Seems like the more North you go, the more hydro is made. Hence PNW and Canada export hydro power. Not sure if Europe has the same trend
Yeah as soon as you get up in a plane, heading east across Canada, it seems like it's 50/50 land/water. A lot of times the routes sweep into northern US. That might have been nixed (fallout from 911?), the US got stickier about Canadian commercial flights dipping into the States?
That air flight problem has to do with the privatization of air traffic control. Canada has downsized air traffic control staff to handle only normal, fair weather route, so when storm clouds are brewing, the air traffic controllers in the USA, where we have extra people sitting around just in case, cannot re-route to Canada because there is no extra staff in Canada to handle the bad weather traffic. Also Canada now charges a fee to airlines for the time they spend in Canada air space. But USA may also head in this direction. My cousin is a recently retire air traffic controller up near Canada so he would have been invovled in re-routes.
No no it's the new Big Dig Boston Metrorail. Greyed out areas aren't completed yet. 2030? GPS doesn't work underground. Ever gone shopping in Vegas and get lost? We have a new "Roundabout" that is shaped like a ? When fly to Eur-asia you fly "over the pole" well near by anyway ( Live Flight Tracker ✈ FlightAware) https://arc.aiaa.org/doi/abs/10.2514/atcq.22.1.21 Always wondered if you could see the ground or if it always under a cloud layer if you're at FL400. Best way to see the big picture on what's a very long flight. Look at all the rejected energy. Think of the greenhouses and normal houses we could heat with this. Denmark already does this somewhat.
The large reject fraction is an inherent consequence of converting heat energy to mechanical energy. But in general practice, we are still far from the theoretical limits, so there is vast room for improvement. Carnot cycle - Wikipedia Carnot Cycle
I know, but I found the terminology amusing. The numbers do point out something interesting though: despite all the hoopla over super efficient burning of natural gas, the national thermo efficiency remains in the toilet at around a third. One more reason to move to solar and wind without delay.
The only real problem with the super efficient natural gas plants is that we have so few of them. The Chinese have vastly more. Instead, we have more older less efficient gas plants, plus a boatload of even less efficient legacy coal plants, pushing up that reject fraction. And the nuclear plants are likely pushing it up too, though their low thermal efficiency is a bit of a red herring for these purposes.
