This is just f'ing awesome: tiny little solar power plants are sprouting on German balconies. A *million* of them now! This needs to be legalized in the US, ASAP. I want my own balkonkraftwerk.

10000ppm = 25% der Luft in dem Zug ist frisch aus den Lungen der Reisenden. Neben der enorm hohen Infektionsgefahr ist das auch ein Bereich in dem starke Müdigkeit, Kopfschmerzen, Konzentrationsverlust eintreten können und die TSI sieht 5000ppm als reguläres Maximum vor (ohnehin viel zu hoher Wert).
screenshot of the TST 4.2.5.8. Internal air quality with the following text: (1) The quantity and quality of air provided inside the area of vehicles occupied by
passengers and/or staff shall be such that no risk is developed to the health of
passengers or staff additional to those resulting from the external ambient air quality.
This is achieved by complying with the requirements set up below.
A ventilation system shall maintain an acceptable interior CO2 level under operational
conditions.
(2) The CO2 level shall not exceed 5000 ppm in all operating conditions, excepted
in the 2 cases below:
* In case of interruption of the ventilation, due to an interruption of the main power
supply or to a breakdown of the system, an emergency provision shall ensure the
supply of outside air into all passenger and staff areas.
If this emergency provision is ensured through battery supplied forced
ventilation, the duration in which the CO2 level will remain below 10000 ppm
LOC&PAS TSI Version for recommendation – June 2022

shall be defined, assuming a passenger load derived from the load condition
‘design mass under normal payload’.
The conformity assessment procedure is defined in clause 6.2.3.12 of this TSI.
This duration shall not be less than 30 minutes.
The duration shall be recorded in the technical documentation defined in clause
4.2.12 of this TSI.
* In case of switch off or closing of all means of external ventilation, or switch off
of air conditioning system, in order to prevent passengers being exposed to
environmental fumes that may be present, especially in tunnels, and in the event
of a fire, as described in clause 4.2.10.4.2 of this TSI

Some stats from 100 days in on congestion pricing: - Complaints about car-honking are down 70% - The Holland Tunnel has 65% fewer delays at rush hour; time to get thru it is down 48% - 6 million fewer cars - Half as many traffic-related injuries - 1.5 million more visitors to BIDs year over year

How Well Is Congestion Pricing Doing? Very.
One hundred days in, honking is down; bus speeds are up.

For comparison: * All of NASA's budget, combined, is under $25B * USAID's HIV prevention & treatment program (PEPFAR), which provided life-saving drugs for 20 million people, had a budget of $4,2B * Only 11 countries spend more on their *entire militaries* than that. $45B is a staggering sum.

The simple fact is though that it's going to take a long time - much longer than we feel comfortable with - to disentangle our military capabilities from the US. At the same time, it's a mutual entanglement, so I expect the process to play out relatively peaceably unless the WH forces it not to be.

Sinocism: Shockingly, the report also says that the PRC exporters may have been stuffing the channels overseas, as “Chinese OEMs now hold nearly a year’s worth of unsold inventory abroad, much more than the two months of average retail sales inventories in China or the US”. And the inventory overhang in the EU is even greater - 28 months. Have those automakers booked the exports as sales, even if the cars are sitting unsold somewhere overseas?
