The United States will essentially have no laws on the books that enforce how efficient America’s passenger cars and trucks should be.
That’s the practical result of the Trump administration’s yearlong parade of regulatory rollbacks,
capped on Thursday by its killing of the “endangerment finding,”
the scientific determination that required the Environmental Protection Agency to regulate greenhouse gases because of the threat to human health.
“The U.S. no longer has em…

With Latest Rollback, the U.S. Essentially Has No Clean-Car Rules
The E.P.A.’s killing of the “endangerment finding” caps a year of deregulation that is likely to make cars thirstier for gas and less competitive globally, experts say.

Abstract: The period 1980-2000 saw the impressive development of applied superconductivity in high-energy particle accelerators, from single components to long strings of superconducting magnets and high-frequency acceleration cavities. Large and powerful cryogenic systems were designed ancillary to superconducting devices operating generally close to the normal boiling point of helium, but also above 4.2 K in supercritical and below 2 K in superfluid. Low-temperature operation in accelerators also involves considerations of ultra-high vacuum, limited stored energy and beam stability. We recall the rationale for cryogenics in high-energy particle accelerators and review its development over the period of interest, with reference to the main engineering domains of cryostat design and heat loads, cooling schemes, efficient power refrigeration and cryogenic fluid management. In view of its importance and novelty, a specific section is devoted to the developments that led to the LHC at CERN.

#MastodonPoll: Which of the following regulations regarding leaf blowers would you support? Choose as many as you like.
1. Decibel limits
2. Fuel efficiency standards (the relevant metric for cars is miles per gallon, so the corresponding one here would be what, leaves blown per gallon?)
3. Fuel type restrictions (i.e. ban gas-powered ones completely)
4. Full ban, both gas-powered ones and electric
