.@Cornell staff and @CornellEng faculty and students directed drilling for ~2 months through sedimentary rock and into the crystalline bedrock 3 kilometes deep. Now testing for a heat resevoir to demonstrate geothermal deep direct use for district heating earthsourceheat.cornell.edu

@fmfclips It would make sense to take the oral body temperature end point. This would standardize the outcome of variable time and temperature of the sauna

In animals, high temps. can also be associated with increases in blood-brain barrier permeability Hence, a plausible mechanism! At this stage, it’s just an association, but it might be prudent to exercise caution until more science emerges.

Extreme sauna temperatures: There’s some evidence the correlation with Alzheimer’s (reduced risk) breaks down for extreme sauna temperatures (>200 ºF) Your best bet? Keep it <200 ºF until more science emerges

@pbasilstrength power

You don’t need Power Cleans to become explosive I took them out years ago and our program only improved Here's a free guide on why and how to train Power without Cleans With a sample week Do these to get it: 1. Follow me 2. Retweet this 3. Comment "POWER" below I'll DM it

@foundmyfitness I suggest the scientists up their game to describe an endpoint. Heart rate elevation or body temperature ( under tongue). I routinely hit 101 F for an endpoint. An easy sweat is 100F

I believe the benefits of a sauna, primarily driven by activating the heat shock response, are likely replicable in steam rooms and even hot baths. Each modality has its own heat and duration 'parameters,' but the underlying principle remains the same. Personally, I use my 20-minute sauna sessions as a benchmark. If you're familiar with how that feels, you can use it as a baseline to get a likely comparable heat shock response.

@drvolts Can you make real time marginal emission rate (lb CO2 per MWh) availabe on -line so that not only is there a price signal, but there is also a carbon signal, about a actions (incease of lead or decrease of load) affect on the grid emissions ?

@duncancampbell The House at Cornell Tech | Handel Architects A 26 story passive house: all electric

My girlfriend is an architecture masters student who’s also great with data. She’s been super into passive house. Who should she be talking to?

@NiyerClimate I’m a simple engineer. I believe in physics as the reality. Why not just say: if the marginal emission rate at the electrolyzer is 0 (lb CO2per MWh) then the hydrogen is green. Otherwise it’s not. ?

I'm calling this thread "why is the hydrogen PTC so damn hard". You might be wondering "why is the Treasury not out with guidance". I'm going to explore some truly eyewatering edge cases and skip over the basics. But for the uninitiated, here are some links:

I’m heating up one of the most complicated hydrogen tax credit threads I can come up with. It’s gonna be straight up incomprehensible to any of y’all and you’re gonna love it.

@duncancampbell Forget fission. Commonwealth Fusion cfs.energy

Which companies have the best shot at commercializing micro reactors? 10 MW or less only.

@duncancampbell @portlandgeneral I like it , but I would love if it was Level 3

Portland General Electric (@portlandgeneral) recently demonstrated a pole mounted level 2 EV charger that retracts the charging cable from above and extends up to 25 feet after a user scans a QR code. What do you think? Is this the future of public EV charging? And should the utility own it?

@JackNorbeck Spectacular achievement! Very good flow rate. Well done!

Proud to report on the results of our commercial next-gen geothermal pilot project in Nevada. We firmly believe it's important to share the technical details of our performance tests so that y'all can see for yourself that this tech is shovel-ready.

@kevinkircher New York is much cooler: about 185F at 2 miles deep. We are advancing deep direct use of enhanced geothermal for heating the Cornell campus. Earth Source Heat | Cornell University & Cornell Deep Geothermal Heat Research. It is also in the chrystalline basement.

@TimMLatimer OK: It's mid-morning here on the east coast. The suspense is building......

Timeline update: news coming tomorrow now.

We @fervoenergy are going to be making a big announcement on Wednesday and I’m already so excited about it. It’s going to be gamechanging for geothermal.

Standing by as this warming happened is the most irresponsible thing that humans have ever done, @billmckibben writes. nyer.cm/Q0YfNzm

@euggra @duncancampbell Read appendix G of the NYS CLCPA scoping plan. Peak demand will almost double and shift from summer to winter. Site is not loading right now….

Does anyone on #energytwitter know of a reputable report on expected load/energy growth thanks to electrification? Something like “we’ll use ABC more electricity by XYZ”. I understand the fragility of these estimates; just looking for reputable source(s) and their rationale.

@duncancampbell Check in with Deirdre Lord, president of home.themwh.com

What companies do metering and billing management for sites with a bunch of electricity submeters?

@JigarShahDC As I replied on LinkedIn, HPs are the electrification of heat. Very efficient. Only if the marginal source of power is carbon free should they be considered renewable.

@annachittum Let me know when you get any term better than geoexchange. We use “deep direct use” for geothermal.

Large ground-source heat pumps serving a district system ≠ “geothermal”energy. Those are two very different things! What are we calling the former these days? I always liked “geo-exchange” but that doesn’t seem to have caught on…

@ArtemTepler @dchughh1 Is not IRR “internal” and not dependent on source of capital?

@dchughh1 That would be correct, IF you are not using leverage and going all cash.

What is a "Cap Rate"? (Capitalization Rate) The % you would make on your money if you bought a property cash (after all expenses are paid). That's it. Anyone else have anything else to add?

@NiyerClimate I understand. But I think we ( in upstate NY) are a decade or more away from overbuilding WWS so they are curtailed. SO the Long run and current marginal will be the same until 2040 ( NY goal for carbon free grid)

@bertbland Big fan of them! One question that I struggle with around LMEs are around long-run marginal rates vs short-run. The evolving emissions profile of the offsetting project makes it a tad tricky to use

Ugh ok quick thread about "additionality" and why it matters for hydrogen and the exceptions. Wonk level high, impact level high, hot takes only. You have been warned.
