A lot of smart outlets develop problems over time from the inductive surge current on electric motor startup (air conditioner, fridge, dehumidifier). The current ratings in ads are generally for resistive loads. Inductive load limits can be 30% less.

India imposes major rice export ban, triggering inflation fears (www.reuters.com)
 

India on Thursday ordered a halt to its largest rice export category in a move that will roughly halve shipments by the world's largest exporter of the grain, triggering fears of further inflation on global food markets.

Modi’s administration has extended a ban on wheat exports after curbing rice shipments in September 2022. It also capped sugar exports this year as cane yields dropped.

New research puts age of universe at 26.7 billion years, nearly twice as old as previously believed in c/[email protected]

Tired light theory requires:

Distant galaxies to be blurry (they aren’t)
Events in faraway galaxies to happen at the same pace as nearby events (they don’t. Time is dialated just like frequency is redshifted)
Cosmic background radiation would not be a black body
Constants c, G, and hbar would change through the history of the universe.

Good ROI Suggestions? in c/homeassistant
[–] [email protected] 5 points 1 year ago

I think highest/easiest ROI would be devices that alert or avoid bad events.

  • freezer/fridge temp monitors to avoid food going bad (circuit failure, door cracked open, part failure)
  • water leak detectors (water heater, bathroom, sink)
  • open door alarms ( garage door left open overnight, fence door left open that lets dog out)
  • doorbell camera/microphone (unwanted visitors)

Computer simulation provides 4,000 scenarios for a climate turnaround. [9300 that don’t] (phys.org)
 

Paper link: https://www.sciencedirect.com/science/article/pii/S0301421523002276?via%3Dihub

Using an extensive computer simulation of the climate, the global economy and the global energy system, researchers at Paul Scherrer Institute (PSI) have been analyzing different ways of mitigating climate change.

If it is to meet the Paris Agreement target, the worldwide average carbon price in 2030 needs to be equal to today's (2022) highest carbon taxes ($ 130–137 tCO2-1) that are observed in very few countries

Electricity cannot decarbonise the entire system alone, and hydrogen extends electricity's reach to hard-to-electrify sectors

The contribution of nuclear power in electricity production increases in the long-term in the decarbonisation scenarios. This is especially pronounced after 2050/60, when the wind and other renewable potentials are fully exploited and the additional electricity supply to meet the increasing demand needs to remain carbon-free.

They do discuss several commonalities in the paper.
