I would really like another prius to be my daily driver if I ever have to start regularly commuting again to areas I can't get to via public transit.

*dramatic turn*

Anywho my xterra needed the fuel pump replaced to pump its 15mpg's, crapped out and left me stranded way up north earlier this week. Ran me 1k to get done, but sure beats having to buy a new car. I prefer older cars you can work on yourself, but I was not at all equipped to drop the gas tank to change it out (and its zero outside so no) and needed it done quickly so meh.

It's weird to me seeing used car prices go up, I was wanting to ditch this thing for something a bit more practical but nope.
a thousand fucking dollars to replace a fuel pump?...did you use the mechanic from christmas vacation?
you could have bought the tools, the pump, and changed it yourself at the parts store for about 200-300 bucks.
fuel tanks are only held in with 4 bolts...parts stores have loaner stuff, like a jack to raise and lower the fuel tank after you drop the new pump into it

Yep. Was in a sticky situation and wouldn't have been able to get to it for a couple of weeks. Sucks balls.

looks good, but it always looks good...get back to me when they start mass producing them.
It is not mainstream fusion that swallows tens of billions, from what I've seen this has potential, but like all other technologies it will have to work, be practical and economically competitive, including deep geothermal. I like this one because it directly converts fusion power to electric power by pushing back against the magnetic confinement field in pulses. The next generation of reactor should produce power and it is already being built, the 7th I believe. They are obviously privately funded with the government no doubt interested. I didn't hold out much hope for fusion power until I saw this, but it might end up competing with deep geothermal as well a lot of other things. A first generation steam engine a lot to look at it was huge, it was a building, and was piss poor efficient, Watt improved it and many others after him. Deep geothermal wouldn't be much good to a ship, but a compact fusion reactor might be.

my bet is deep geothermal is a no-go. Be a while before we’ll know.

It is good that there are viable alternatives on the horizon, we will see how it works out over the next decade, for most things energy related, including batteries. This fusion idea looks much more viable and pragmatic than others I've seen, apparently they have big private backing who do due diligence with physicists and engineers reporting before dumping in the cash.

I wouldn’t bet too much on that. It’s already the modern way of heating greenhouses in NL. Some homes attached too. Half a large city on it in Germany iirc. Enough successful tests done and experience gained over the past years to expand heavily over the next few years. These go ~2 miles deep.

Do you have any info on wattage and lifetime of a borehole?

(edit) they’re using temps of 50 to 80 degrees. That’s ok for space heating, but useless for electric.

Deep geothermal goes 10 miles or more deep using gyrotrons to blast a borehole lined in glass and has the thermal potential to power current coal thermal power stations for instance with just a few boreholes. Tests are underway in America and if it works the technology could be applied nearly anywhere.

Ah yes, I had a feeling I should have read a few earlier posts for context. Can I still get in on the bet :lol: Germany has a few that are partly used for electricity too but it’s just megawatts.

The lifetime of these boreholes is still unknown because none are old enough to determine if they’ll meet or exceed the projected lifetime. Greenhouse industry can afford to invest in it (as it saves natural gas which as you know is now pricey) but there are still many uncertainties.

I saw an interesting map of Europe from a geothermal perspective. Apparently a key feature is permeable ground at depth. One can pump water in at one location, and pump hot water out some distance away. This hugely multiplies the size of any one station’s available heat reservoir.

Put them up high and space them a bit, cut a deal and use some of the energy for water desalination and irrigation, sheep, cattle and wildlife can share the area and grazing too. There is talk of large solar projects in Africa, but energy storage would be an issue, though offsetting the solar arrays by a few time zones east would help with peak loads in Europe further to the west.

This is solar alone, there is also wind, wave and perhaps deep geothermal, energy storage is the key to more renewable energy use and increased grid efficiency.

This guy does mostly aviation videos, but does backyard updates on norcal weather. I saw a lot of the bigger jet burners in use after Michael, but I had never seen one of the self-contained ones. Pretty neat.

Bearing in mind Elon is involved, so expect over promising! However EVs are much easier and cheaper to make than ICE vehicles, most of the cost is the battery and those prices have been plummeting as the options increase. A small plug in at home medium range EV under $10K would sell!

We should as a globe pay (ideally a nice annual check using satellites to determine if their land is increasing or decreasing in its plant mass to determine if they get more or less money for their land's particular air factory). these people living in our last thriving planetary lungs to just chill the fuck out and help their land thrive and not chop it down so IKEA can supply the next wave of kids getting their first apartment.

i saw that same episode on 60min last night as well
