Très fier d'annoncer la sortie d'un nouveau #livre sur la transition environnementale des entreprises! Avec @Alex_Denis_, @RetailleauElise, @Lucas3Gigli et Luc-Olivier Briand. dunod.com/entreprise-et-…

I can no longer in good conscience remain on this app and indirectly support its main owner. I am now BlueSky jbvaujour.bsky.social

@tomas_lamy C'est quand même moyennement comparable avec le TWh livré à la prise à Paris

@VaujourJB MTPA délivré ▶️bcm▶️x10 = Twh DES

Le Qatar pour un peu plus de 60 milliards de capex va mettre en ligne 1000 (oui 1000 Twh) de LNG d’ici 2028, les 6 prospectifs EPR*2* qui coûteront entre 80 et 100 milliards en mettront en ligne 70 d’ici 2045 en étant très optimiste si ça arrive un jour. 3615 ordres de grandeur

Are Americans really OK with this? $Trump Coin means that foreign governments can essentially make themselves anonymous and then buy the coin in order to provide Trump with trading fees, and increase the value of his holdings in order to curry favors. There will be no way to really track this or tell how much Trump is making from Foreign governments. Are people really OK with this?

Nvidia's Jim Fan: We're training robots in a simulation that accelerates physics by 10,000x. The robots undergo 1 year of intense training in a virtual “dojo”, but take only ~50 minutes of wall clock time. Those who still remember Dragonball Z will recognize the room where a few minutes outside equal years in the room. This is how robot training works. This is exponential development.

@tomas_lamy @epelgrino Tout le monde s'excite sur cette étude mais elle est très loin d'établir un lien entre CSC et modulation d'une part et d'autre part la seule piste éventuelle est au mieux de second ordre

@epelgrino La flotte modulait avant les enr faute à sa part prépondérante dans mix dont la production nominale excédait les creux journaliers (la nuit) et EDF avait une certaine fierté a le faire, les seuls au monde, les rois du pétrole…

La modulation est une connerie que seuls nous 🇫🇷, plus malins que tout le monde, faisons subir à notre parc ⚛️ par pure idéologie pro ENR.

over a 36-hour livestream, I built a neutron-producing nuclear fusor in my kitchen using Claude. successfully achieving nuclear fusion, entirely assisted by AI. this was my first hardware project!—full story below

The irony

@SnowOrDeath @dieworkwear

@dieworkwear Why not escalate? Say something about white socks and sandals.

POV: you told men that golf polos are not stylish

@picharbonnier Imagine being 40 years old and you have to provide for your kids (2), your parents (2), your grandparents (4) and potentially some great grandparents (2 maybe). So that would be 9 people to feed, house, shelter, cure, etc for an able adult.

How do you recover from this as a country ?

@tomas_lamy Ton ROI c'est le tx de rendement qui met ton flux de treso actualisé à 0. Si ton cash out initial est plus important, il faut supposer que ton MWh produit / unité de CAPEX est le même dans les deux cas pour que ça soit vrai.

@VaujourJB Ce qui influ absolument pas sur la tendance. C’est une question de retour sur investissements

Oh c’est beau ça. Finance 101. Sorcellerie pour beaucoup

@MLehort @tomas_lamy @qwevino_0 Ça n'a aucun sens, au-delà de 20 ans, la valeur actuelle des cash flow converge rapidement vers 0

@tomas_lamy @qwevino_0 Miam miam

After millions of views spreading lies about the Palisades firefighters lacking water because of regulations, the boring truth comes late like usual and wont be shared. Here it is: 1 - Reservoirs and water tanks were at normal levels and completely full before the fire. 2 - All 114 city water supply tanks were fully stocked pre-fire. 3 - A 15-hour surge at four times normal demand reduced water pressure. 4 - High demand at lower elevations slowed refilling tanks at higher elevations. 5 - This unprecedented fire was fueled by 8 months of no rain and 85 MPH winds. Water is being brought in continuously. 6 - Even if, like Trump claimed, the protection of the Delta Smelt caused over regulation by California, it's the FEDERAL Endangered Species Act that requires the protection of endangered species like the Delta Smelt and their habitats, not Gavin Newsom or California. I expect the comments to me filled with people personally attacking me for putting this information out. All it does is show that you are unintelligent. Thanks.
