Nice looking ebike...
Wow. Ce prototype de l'opérateur Bond Mobility ne ressemble à rien de connu à ce jour sur le marché du vélo en libre-service. Curieux de voir s'il sera un jour déployé 🚲⚡

My hypothesis is the filter is basically duration: the earth's unusual formation has given it a rare, dense, hot core and plate tectonics that has kept the biosphere active (see Mars), and, that, and the sun's stability and the mere chance life wasn't destroyed by a nearby supernova gave humans the time to evolve. We can't blow this gift.
Whitepill for the day. TL;DR we are probably alone in this galaxy.

There are many types of Turbomachinery engineers. It’s always the Aero guys who think they can design a whole engine. Real engines fail in mechanical integrity, or rotor dynamics. Secondary air flows and sealing engineers are unsung heros and are what make supercritical feasible.

Good analysis on the Marquz/Bezzecchi incident at the Qatar MotoGP. This isn't the first time the exceptional corner speed of the Aprilia over the Ducati has led to different racing line and a collision. Marquez standing his bike partially up pre-impact is the only reason he didn't go down as well.

The Singularity is Near.
Across our projects @GoogleDeepMind, we are witnessing a genuine phase transition in the pace of scientific discovery. You will see a glimpse of this in our releases in the next few weeks.

Segway introduced an enclosed electric scooter, the "X cruiser" at EICMA. Licensing intellectual property from BMW, it uses a similar roll-cage and 4-point belt system from the long-out-of-production BMW C1, and will not require a helmet in the fully enclosed version.

More information below. No performance specs, but this likely competes with 125cc class ICE scooters. I expect this to be extremely popular in Paris -- just as the BMW C1 was. Reasons: no helmet hair and decent weather protection. thepack.news/segway-takes-on…

People think NetZero means luxury communism and printing a trillion dollars a year to sequester CO2. It refers to the size of the global economy necessary to solve the climate problem the dumb way. And the returns of the governments and funds that try it. The only way out is through. Reflect sunlight, enhance weathering, expand solar supply.
the path to a stable climate does not run through NetZero.

Evidence is growing that we’re turning the corner on productivity. US productivity grew at a 3.6% annual rate this past quarter. That’s more than double the 1.5% average from 2007-2019. The new numbers put me further ahead for my bet with Bob Gordon about productivity growth in the 2020s. 💪 Here’s how far the US is now ahead of the CBO estimate at the start of the decade (before they knew about the pandemic or LLMs) courtesy of @jasonfurman’s Econvitals.

Perhaps the smartest e-motorcycle to come out recently, other than the Stark Varg. Lightweight e-motorcycles designed for city and suburban riding make sense, while higher performance ones that also need decent motorway range don't.
Zero's electric supermoto Project Ventura was unveiled today at Eicma in Milan. #motorcycle #MCN #eicma #Supermoto #electric

It's notable that the Zero Project Ventura is rated at 65 mph continuous, with burst speed to 80 or so. It probably has an ~8 kWh battery, and power goes up with V^3. So perhaps 3kW at 50 mph, more like 8kW at 65 -- it will not go far on the motorway, and even less at 80!

This lady crashed the housing pipeline for San Francisco a decade ago and now she’s going to crash like anything that requires home or auto insurance in the entire state of California.
4.8 million votes counted and the only statewide race worth watching is the Insurance Commissioner race, with progressive Jane Kim narrowly up 51.7%/48.3% over State Senator Ben Allen in a D vs D race

I think I designed this in 2013…
ヤマハが、電動スクーター「NMAX E」「XENTER E」を発表。 どちらも最高出力7.5kW(定格6.7kW)、最大トルク33.3N・mのモーターと、容量3.5kWhのリチウムイオンバッテリーをベルトドライブで組み合わせる。 バッテリーは車体に固定する方式で、家庭の電源や公共の充電器(AC Type 2)で充電でき、充電時間(0~100%)は5.5時間。 【バッテリー除く車重/シート高/航続/出力/価格】 121kg/770mm/104[108]km/10.2ps/7,799ユーロ(約138万円) [ ]内はXENTER E news.webike.net/motorcycle/6…

My version had a belt drive from the e-motor like the Yamaha, a 2kWh lithium-iron-phosphate pack (it could have been almost 4kWh with 2026 high-energy cells) -- and a 125cc range extender/generator set.

I think it was Ray Kurzweil who pointed out that people are really bad at understanding exponentials . . .
Just made an update from "my" Solar reality vs IEA graph for an upcoming book called "Power to the People". The difference is still going strong...

lol. In 1910, the Italian futurists wanted to raze Venice and build a modern city there. I’m sympathetic to both impulses, if not necessarily a supporter.
Was chatting with a guy last night in SF He wants to terraform SF Tear down the half-slum half civilized cardboard settler slop And build a real city in its place Unfathomably harder than building a rocket and chopsticks, but I can't blame anyone for taking easy path in life

Iterating on projects and building in-house expertise is vital. California, for instance, has tried to sub-contract every part of its HSR effort. How has that gone?
The reason Italy and France build infrastructure so cheaply is that 80% of the planning, design and project management is done in house. When I was a consultant, my company was charging more than 3x my salary for my work. Can we please get serious about project delivery as a country?

Repeat after me until you memorize this geopolitical axiom: energy security will always & under any given circumstances trump energy transition; never ever put yourself at the mercy of the weather; cheap as possible, affordable & always available energy means all-in energy mix.
