The danger of lithium ion batteries

 CBS News:

Lithium-ion battery sparks fire that kills 1 and injures 10, FDNY says

...

Failed lithium-ion batteries, which power things like E-bikes, scooters, cell phones and more, have been the cause of many fires. Overheated or defective batteries can catch fire or even explode, according to the National Fire Protection Association (NFPA). FDNY officials said in September 2022 that at least 150 fires had been started by the devices in New York City that year.

"When (lithium-ion batteries) do fail, they fail very unexpectedly and very violently. It's almost like a blowtorch effect," FDNY Chief Fire Marshal Daniel Flynn told CBS New York.

The NFPA recommends never charging a lithium-ion battery overnight or leaving a battery on the charger after it's fully charged. Batteries should be kept at room temperature, should be stored away from other flammable materials, and should not be charged under a pillow, on a bed, or on a couch.
...

There have also been reports of fires caused by the batteries in electric cars.  They do not look like the answer to using fossil fuels for transportation.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t

Bin Laden's concern about Zarqawi's remains

James Robbins: ... Bin Laden suggests that President Bush should allow Zarqawi’s body to be returned to his family in Jordan, but this is a matter that is up to the Jordanian government, which so far has not shown much interest in facilitating a homecoming. Bin Laden mocks King Abdullah II, calling him a Coalition minion, and asking “w hat scares you about Abu Musab after he’s dead? You know that his funeral, if allowed to happen, would be a huge funeral showing the extent of sympathy with the mujahedin.” A large crowd would definitely turn out, though most people would be on hand to demonstrate their anger and disgust. Last November’s hotel bombings in Amman , masterminded by Zarqawi, are still fresh in people’s memory, and mentioning them to Jordanians has the same visceral impact as memory of the 9/11 attacks does here. Jordan has adopted a zero-tolerance policy towards those who choose to mourn the country’s least favorite son, and four opposition members of parliament who paid con
