Darüber redet niemand: Die #Klimabilanz dieses #Elektro- #LKW ist absurd.

Coast to Coast #Roadtrip mit dem #Elektrotruck: In der dritten Woche mit dem neuen #DAF #XD #Electric (525 kWh #LFP Akku) geht es vom Mittelmeer an die Nordsee. In der Mitte tausche ich die Ladung mit einem Kollegen und transportiere einen Messestand zur EVS38 nach Schweden. Und eins kann ich vorab sagen: Es wird richtig eng. Natürlich stehe ich auch wieder im Stau vor dem Brenner.

Today I'm sharing this interesting article about the possible next gen of turbofan engines for mid-range aircraft. (#Hydrogen ecosystem facing a delay of 5-10 years, amid foreseeable scarcity and competing #SAF demand.)
flightglobal.com/engines/ge-ae

Open rotor or not, what thrilled me most in reading, was the mention of a hybrid #electric mode. It means, the fan could be powered without combustion in certain flight phases! Or the core engine downsized to a functional range extender, because peak power could be available electrically! YES!!

Ok, to be serious, it still needs tons of development and current power target is 600KW in electric propulsion, whereas mid-range jetliners need megawatt power plants. But still!!

GE Aerospace's GE9X on wing of 747
Flight GlobalGE Aerospace and Pratt take divergent paths toward developing engines for next narrowbody jetsAirbus and Boeing might still be a decade from finalising their requirements, but CFM International and competitor Pratt & Whitney (P&W) have little time to waste. They face a decision with immense ramifications: dive into developing a radically new powerplant, or invest to update and improve the conventional turbofan architecture.

#California’s ability to set tough #emissions standards dates back to 1970, when heavy #smog clouded the skies of #LosAngeles. Since then, the #state has received dozens of waivers allowing a range of policies to reduce #pollution & #GreenhouseGas emissions. #AirQuality has improved, but remains poor in some regions, particularly in the CentralValley. #State leaders see the transition to #electric #cars as a tool to improve it.

…For more than 50 years, the #CleanAirAct has allowed #California to set pollution standards that are stricter than federal rules, as long as the state obtains waivers for them from the #EPA.
The resolutions #Trump signed Thurs also revoke waivers for 2 other CA #CleanAir policies. One blocks CA from requiring that ½ of all new #trucks sold in the #state be #electric by 2035. Another stops the state from putting limits on allowable #emissions of nitrogen oxide from #cars & trucks.

Dozens of Solenoids turn Vintage Typewriter into a Printer.

An electric typewriter is a rare and wonderful thrift store find, and even better if it still works. Unfortunately, there’s not as much use for these electromechanical beauties, so if you find one, why not follow [Konstantin Schauwecker’s] lead and turn it into a printer?

Cooling our old house in summer. This house was built in 1940 so it has gone through all the stages and types of heating you can probably imagine.

We installed a ductless ("air source") heat pump a few years back. This was a revelation after 15 years of "window management" and fans to keep a lid on the intense heat of the Alberni Valley.

It has made a wonderful difference both for cheaper heating in winter and newfound cooling potential in summer. We only could get one big enough for two of three floors.

So basement and main floor have a register like this.

Today, on the first official hot day of summer it is:
Outside temp: 33°C
Top Floor (windows open, fans on): 30°C
Main Floor (windows closed HP set to 23°C): 25°C
Basement (HP set to 23): I would estimate 23°C

We also have a hybrid HP/Electric hot water tank in the basement that I have blowing its outlet air into the room for summer to help keep the temperature down in the basement.
