No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.

👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em

 The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)
We see strong demand for hydrogen from steel in particular as producers all over Europe (🇸🇪🇷🇴🇩🇪🇦🇹🇮🇹🇫🇷) plan to move to direct reduced iron (DRI) processes – and so do others around the globe, as recent announcements from China and Korea have shown. (6/17)
Given the 2050 climate neutrality target, we see the demand from refineries vanish, to be replaced with demand from steel. Overall, by 2050 we expect that almost 300 TWh of low-carbon hydrogen will be required. Remarkably, that is similar to hydrogen demand in 2020. (7/17)
Having established inescapable demand, we can start thinking about matching supply. European and neighbouring countries have a high renewable energy potential that can be tapped for direct-electric applications and renewable hydrogen production. (8/17)
In our analysis, we consider two scenarios with renewable hydrogen production: The BLUE-GREEN scenario also includes SMRCCS as an option in 🇳🇱🇳🇴🇬🇧because those countries are actively developing the technology. (9/17)
Taking into account asset lifecycles and political commitments in the BLUE-GREEN scenario, fossil-based hydrogen with carbon capture will remain a viable investment until the 2030s. However, … (10/17)
… strong policies for renewable hydrogen will shorten the investment window for fossil hydrogen, likely closing it before the end of the 2020s as is the outcome of the FAST GREEN scenario which is in line with EU Hydrogen strategy electrolyser targets. (11/17)
But producing the required quantities of H2, especially with renewables, is only one piece of the puzzle. Geography adds to the challenge: steel, ammonia, refineries and chemical plants are widely distributed across Europe. Their demand can vary by an order of magnitude. (12/17)
Ensuring reliable supply means accounting for various weather and seasonal effects. In our analysis, we model salt caverns to take care of the variation in renewables to produce “flat hydrogen”. That led us to derive least-cost pipeline corridors for hydrogen transport. (13/17)
Consequently, we identify 4 robust no-regret corridors for early hydrogen pipelines and storage based on industrial demand in different parts of Europe. The demand identified is unlikely to justify a large, pan-European H2 backbone. (14/17)
We do note, however, that our assumptions are limited to inescapable demand from industry. Adding potential hydrogen demand from power, aviation and shipping sectors is likely to strengthen the case for a more expansive network of H2 pipelines. (15/17)
Nonetheless, even under most optimistic scenarios any future H2 network will be smaller than the current natgas network. A no-regret vision for H2 infrastructure reduces the risk of oversizing by focusing on inescapable demand, robust green hydrogen corridors and storage. (16/17)

HOW TO LAST LONGER IN BED😋(18+)

Some men will last for hours while some men will have the audacity to last for 2mins. But don't worry, because you might even last for 8hrs in bed & she will end up cheating on you. A THREAD😂

Are you a virgin?

RULE 1: DO NOT judge yourself with just 1 round. That's pathetic of you.

Who knows, you might be Johnny sins or a fuck machine from your round 2


So I advice you masturbate your first round off before sex, or you allow your lady try this on you👇

(put your imaginations into work)
now let's get dirty....🤤

• hold his dick and rub it around your pussy, dip it in so that your pussy juice will wet it & get it ready.

The #RELAx trial has been published today in @JAMA. It was coordinated by Anna Algera. This thread is to explain the rationale, what we did, the findings and the meaning.
The rationale of #RELAx is based on the following

First, there is NO adequate evidence on the level of PEEP in non-ARDS patients. Most of the studies are old, conducted in post-surgical patients (short-term ventilation), and were not powered to detect differences in patient-centered

Second, despite the absence of evidence, the levels of PEEP used in non-ARDS patients increased over years, from 5 to 7/8 cmH2O, probably as a reflection of studies and practice in ARDS

Third, one IPDM showed that higher levels of PEEP could benefit more severe ARDS patients. However, opposite trends (higher mortality and longer ventilation) were found in mild ARDS with higher PEEP (despite not powered to be statistically

Fourth, most of the weaning protocols include PEEP ≤ 5 cmH2O as a criterion for readiness to wean. Theoretically, a standardized liberal strategy of higher PEEP could delay weaning in some

New Cannabis Based Menu for Chao Phraya Hospital patients (service being rolled out to other hospitals too)
"This cannabis special menu is bringing different parts of the cannabis plant to use with leaves to cook as ingredients in food" #cannabis #Thailand


Whilst patients in the UK are still being denied with almost no progress with #NHS Amazing to see how much progress is being made with #cannabis as #medicine in #Thailand is the same 2 year period:

A Thread: 1/10 #Thailand allowed #cannabis #medicine in Jan 2019, 2 months after the UK.
NOW:
Is approved for 160+ conditions (everyone!)
Village doctors, clinics and hospitals can supply approved products or grow and produce their own, from nearly 100 approved formulas

2/10 - Average monthly prescription cost is £20-£30.
Educational programs started for the Medical Profession within 3 months, for many others at 6 months and school kids after a year. (Google Dr Ganja - see photo)


3/10 - Shortly they will launch a new policy for any individual or collectives to grow #cannabis for #medicine for themselves and any surplus material can be sold to the government for use in centralised production.

Folks, we need to talk about this Vitamin D trial. I have no stake in this game - take Vitamin D if you want but this pre-print is super sus.

The paper is presented as a randomized trial of vitamin D supplementation in hospitalized patients with COVID. Interesting and important question! And the results appear dramatic:


If true, this would be one of (if not THE most) effective treatments for COVID. But there are problems...

The first clue something is up is that the randomized groups aren't the same size:


It took me a while to figure out why this was, then I saw in the text that INDIVIDUALS were not randomized, WARDS in the hospital were.

breaking my social media fast, which may or may not exist anymore, to share something i found really really helpful from today's therapy sesh. i figured out why i (we?) have so much trouble celebrating our wins

so ive been in therapy for 100 years. still anxious, but im pretty sure i was born that way so i'll stay that way. still depressed too, which i thought id be cured of by now. aa few sessions ago we talked about what i think a return to health 'should' look like

initially i figured itd look like being the person i was before i got depressed. energetic, not needing pep talks to do shit like go outside, cooking everyday, working out at least 30 mins at least 3 days a week, calling my mom everyday, etc.

that session i realized that im a completely different person than i was before i got depressed. also the world has changed a lot & things are just done differently now. not allowing for those things had me reaching for shit that was impossible.

so i make some concessions but say that i *still* want to be able to do some things that i dont want to do. like i cant just sit on the couch and never move in the name of accepting who i am, which is A Bitch Who Don't Like To Move. i still want to be able to eve if i dont want

Ashta Siddhi

Ashta Siddhi is mentioned in Patanjali Yog sutra and can be obtained by very few through countless years of practice and devotion to all eight limbs of Ashtanga Yoga.

Siddhi can loosely be translated as accomplishment or a special power or unusual skill.


The eight Siddhis are:

1. Anima: Reducing one’s physical self to the size of an atom.

2. Mahima: Expanding one’s physical self to infinite level

3. Garima: Making one’s physical self so heavy as immovable by others

4. Laghima: Becoming almost weightless


5. Prapti: Being able travel anywhere in the Universe

6. Prakamya: Can know & understand what is going on in one’s mind. Can understand other person’s min.

7. Ishitva: Possessing title of Bhagwan

8. Vashitva: A seeker can subdue any person/thing

(Hanuman Jayanti is coming)


Hanumanji not only possessed all eight siddhis, but was also blessed by Sita mata as “Ashta Siddhi Nau Nidhi Ke Daata”.

When Hanumanji first reaches to Lanka on his mission to find Sita, he makes use of anima so as to be discrete in enemy territory.


He uses it again when he approaches Sita mata for the first time – reducing his size to that of a schoolboy, to avoid scaring her. He uses mahima to outwit & overpowers
the demons.

1/ 👋 Excited to share what we’ve been building at https://t.co/GOQJ7LjQ2t + we are going to tweetstorm our progress every week!

Week 1 highlights: getting shortlisted for YC W2019🤞, acquiring a premium domain💰, meeting Substack's @hamishmckenzie and Stripe CEO @patrickc 🤩

2/ So what is Brew?

brew / bru : / to make (beer, coffee etc.) / verb: begin to develop 🌱

A place for you to enjoy premium content while supporting your favorite creators. Sort of like a ‘Consumer-facing Patreon’ cc @jackconte

(we’re still working on the pitch)

3/ So, why be so transparent? Two words: launch strategy.

jk 😅 a) I loooove doing something consistently for a long period of time b) limited downside and infinite upside (feedback, accountability, reach).
cc @altimor, @pmarca


4/ https://t.co/GOQJ7LjQ2t domain 🍻

It started with a cold email. Guess what? He was using BuyMeACoffee on his blog, and was excited to hear about what we're building next. Within 2w, we signed the deal at @Escrowcom's SF office. You’re a pleasure to work with @MichaelCyger!

5/ @ycombinator's invite for the in-person interview arrived that evening. Quite a day!

Thanks @patio11 for the thoughtful feedback on our YC application, and @gabhubert for your directions on positioning the product — set the tone for our pitch!

1/ Someone emailed me asking how to break into VC, so I wanted to answer on Twitter where others could see and contribute to the conversation.

2/ “Being a VC” can mean a lot of different things, so it’s worth asking:

What actual activities do you want to do?

- Deep market analysis?
- Be in the flow of information and people?
- Make deals?
- Work closely w/ founders over time (e.g take board seats?)
- Manage capital?

3/ It’s worth specifying what type of VC you might like to become — as there are different archetypes. E.g.

- Benchmark (Lead series A/B - couple investments a year)
- First Round (Lead seed rounds, partner w/ a few companies a year)
- SV Angel (Make lots of seed investments)

4/ Continued:

Expa - Incubate companies

YC / Village Global - Build a platform to help entrepreneurs at scale

Do you want to join a firm or start one? There’s a lot to consider.

Different paths will require different skillsets & sets of experiences.

5/ Since the person who wrote the email is a young person trying to break into VC by joining a firm (and who doesn’t want to start a company), I’ll tailor this tweet storm to that goal. There’s some overlap.

#தினம்_ஒரு_திருவாசகம்
தொல்லை இரும்பிறவிச் சூழும் தளை நீக்கி
அல்லல் அறுத்து ஆனந்தம் ஆக்கியதே – எல்லை
மருவா நெறியளிக்கும் வாதவூர் எங்கோன்
திருவாசகம் என்னும் தேன்

பொருள்:
1.எப்போது ஆரம்பித்தது என அறியப்படமுடியாத தொலை காலமாக (தொல்லை)

2. இருந்து வரும் (இரும்)


3.பிறவிப் பயணத்திலே ஆழ்த்துகின்ற (பிறவி சூழும்)

4.அறியாமையாகிய இடரை (தளை)

5.அகற்றி (நீக்கி),

6.அதன் விளைவால் சுகதுக்கமெனும் துயரங்கள் விலக (அல்லல் அறுத்து),

7.முழுநிறைவாய்த் தன்னுளே இறைவனை உணர்த்துவதே (ஆனந்த மாக்கியதே),

8.பிறந்து இறக்கும் காலவெளிகளில் (எல்லை)

9.பிணைக்காமல் (மருவா)

11.என் தலைவனான மாணிக்க வாசகரின் (வாதவூரெங்கோன்)

12.திருவாசகம் எனும் தேன் (திருவா சகமென்னுந் தேன்)

முதல்வரி: பிறவி என்பது முன்வினை விதையால் முளைப்பதோர் பெருமரம். அந்த ‘முன்வினை’ எங்கு ஆரம்பித்தது எனச் சொல்ல இயலாது. ஆனால் ‘அறியாமை’ ஒன்றே ஆசைக்கும்,, அச்சத்துக்கும் காரணம் என்பதால், அவையே வினைகளை விளைவிப்பன என்பதால், தொடர்ந்து வரும் பிறவிகளுக்கு, ‘அறியாமையே’ காரணம்

அறியாமைக்கு ஆரம்பம் கிடையாது. நமக்கு ஒரு பொருளைப் பற்றிய அறிவு எப்போதிருந்து இல்லை? அதைச் சொல்ல முடியாது. அதனாலேதான் முதலடியில், ஆரம்பமில்லாத அஞ்ஞானத்தை பிறவிகளுக்குக் காரணமாகச் சொல்லியது. ஆனால் அறியாமை, அறிவின் எழுச்சியால், அப்போதே முடிந்து விடும்.
