"The core simple description of the problem is that EV fast charging consumes thousands of houses’ worth of power on one city block. So a single fast charging station will consume somewhere between 500 to 2000 Ohms worth of power instantaneously during certain times of the day, but it's consuming that load in one concentrated location. So, in order to provide that load, you have to rebuild the entire local grid in many cases or install large very expensive transformers on site that can take years to build and years to install. We get around that problem by augmenting the local grid with energy storage systems that provide that load and supplement the local grid as opposed to rebuilding it entirely. "

“Surgeons in Boston have transplanted a kidney from a genetically engineered pig into an ailing 62-year-old man, the first procedure of its kind. If successful, the breakthrough offers hope to hundreds of thousands of Americans whose kidneys have failed.

So far, the signs are promising.

Kidneys remove waste products and excess fluid from the blood. The new kidney began producing urine shortly after the surgery last weekend and the patient’s condition continues to improve, according to physicians at Massachusetts General Hospital, known as Mass General. He is already walking the halls of the hospital and may be discharged soon.” (The New York Times)
