Can Electric Cars on the Highway Emulate Plane-to-Plane Refueling?

Posted by in categories: military, sustainability

Jet fighters can’t carry a huge tank of fuel because it would slow them down. Instead they have recourse to air-to-air refueling, using massive tanker planes as their gas stations. If electric vehicles could pull off the same kind of peer-to-peer charging scheme it could eliminate range phobia and speed the adoption of EVs.


On-the-road peer-to-peer charging depends on steerable booms to make the connection.

Musk tweet knocks $14bn off Tesla market value

Posted by in categories: Elon Musk, finance, law, sustainability, transportation

Elon Musk tweeted a complaint about Tesla’s share price that wiped $14bn off the company’s stock market value on Friday morning.

The seven-word tweet was the latest controversial outburst from the outspoken chief executive, whose outpourings on Twitter have landed him in hot water before. An incorrect claim in the middle of 2018 that he was close to a buyout of Tesla led to a complaint from the US Department of Justice and a settlement that involved Mr Musk agreeing not to issue market-moving tweets in future without first clearing them with his company’s legal department.

Tesla did not immediately confirm whether Mr Musk’s tweet had been given legal clearance, and did not respond to a question about whether the company currently has a general counsel. Tesla lost three general counsels last year, one of them quitting after only two months.

Study finds high blood pressure medications safe for patients with COVID-19 disease

Posted by in categories: biotech/medical, health

This is very surreal. A study was done to assess the safety of common drugs, and COVID, and whether taking them leads to severe symptoms. There has been concern as these drugs increase ACE2 receptors coronavirus binds to. So someone had the bright idea of going through over 12,000 digital patients records to come up with the conclusion the drugs are safe to take and they do not cause worse symptoms. No animal studies, no clinical trials, and this was actually published.

“For the study, the researchers identified patients in the NYU Langone Health electronic health record with COVID-19 test results. For each identified patient with COVID-19 test results, the team discretely extracted medical history needed for the analysis, which compared treated and untreated patients.”

First you do a mouse study at least to review how coronavirus behaves in mice who are given the drugs, and compare it to mice not given the drugs. If science has been reduced to just going over records and coming to a conclusion, with no experimentation I have officially lost my mind.

‘Hydrogen-On-Tap’ Device Turns Trucks Into Fuel-Efficient Vehicles

Posted by in categories: energy, transportation

A cherry-red pickup truck in Carmel, Indiana runs on hydrogen without carrying any fuel cells. The engineer who developed this “hydrogen-on-tap” system hopes it can someday power cargo trucks and cruise ships worldwide.


The city of Carmel, Ind., has trucks for plowing snow, salting streets, and carrying landscaping equipment. But one cherry-red pickup can do something no other vehicle can: produce its own hydrogen.

A 45-kilogram metal box sits in the bed of the work truck. When a driver starts the engine, the device automatically begins concocting the colorless, odorless gas, which feeds into the engine’s intake manifold. This prevents the truck from guzzling gasoline until the hydrogen supply runs out. The pickup has no fuel cell module, a standard component in most hydrogen vehicles. No high-pressure storage tanks or refueling pumps are needed, either.
