Ammonia (NH3) has been proposed as a shipping fuel, but its potentially harmful side effects are little known.

👉 What do we need for a sustainable energy world according to Elon Musk? 👉 Elon Musk and his team have calculated that achieving this goal requires 240 TWh of energy storage, 30 TW of renewable power generation, and an investment of $10 trillion in manufacturing capabilities.

👉 Chinese energy giant Sinopec - China Petroleum & Chemical Corporation expects oil demand in China to peak before 2027 which is earlier than previously forecasted.

Rolling resistance can be represented as: Fr = Crr*m*g It depends on the vehicle’s mass 𝑚, the acceleration constant g, and the rolling resistance coefficient Crr. Crr depends on road roughness, road material, tire material, tire structure, temperature, pattern, etc.

The idea of technological neutrality means that policymakers should avoid choosing specific technologies to support. Instead, it should be up to the customers to decide which technologies become popular.

❗❗ "German manufacturer Daimler Truck is to receive 235 mil. EUR of state funding in Germany for its Pegasus project, which will develop, produce and test 100 of its liquid-hydrogen heavy-duty trucks in real customer operation."❗ ❗

It is possible to reduce iron ore using green hydrogen. Iron ore is reduced by H2  via a gas-solid reaction in a shaft furnace.

👉 YOUR TESLA - A PART OF A COLLABORATIVE ECONOMY?🤔 Tesla - Car by day, bitcoin miner by night?

#Xiaomi SU7 is successful not just because its price is lower than the Porsche Taycan, but mainly because it offers an #EV with apps and a digital customer experience that is far superior to that of the #Porsche #Taycan.

#hydrogen is very terrible battery compared to #battery energy storage system

👉A software-defined vehicle (SDV) refers to a #vehicles that can have its features and functions updated throughout its lifespan via over-the-air (OTA) updates.

#Safety pin has remained unchanged since its invention by Walter Hunt, as it effectively serves its purpose. Similarly, the #Tesla #Model Y "Juniper" exhibits a design that fulfills its intended function. If something has a good timeless design, there isn't much to improve.

#airbus Pauses Plans to Bring NextGen #eVTOL Aircraft to Market. The Airbus engineering team appears to view limitations in available battery technology as a barrier to progress with current #eVTOL plans. My calc proves they were right.

👉The power of vertical integration. 💪 Comparison between #BYD Seal and VW ID.4C The BYD 8-in-1 powertrain includes the BMS, VCU, inverter, PDU, OBC-DC/DC merged into one unit, and the gearbox/e-motor in another.

I considered the carbon intensity of producing #steel, #aluminum, and carbon fiber in China. I picked China because it makes the largest amount of these materials. 👉 The carbon intensity of: steel ~2 kg CO2/kg, aluminium ~13 kg CO2/kg, carbon fiber ~30 kg CO2/kg.

In cold winter more energy is consumed by EV, because heating the cabin which reduces its range. Tesla Model Y #Juniper has acoustic double-pane glass acoustic glass for all windows and both windshields which will help with acoustics and insulation.

The Chinese #DeepSeeek identified "tungsten counterfeits," part of the Stargate AI plan, in a very affordable way, achieving almost 100% accuracy. 😊

Most of electric motors in EVs use rare earth magnets. According to my calculation 87% EVs use PMSMs, 10% IMs (mostly in dual motor versions) and 3% use WRSMs.
