The Strength of Ancient Roman Concrete

Concrete walls at the Hamaoka Nuclear Power Plant were found to have become stronger over their lifetime
Concrete walls at the Hamaoka Nuclear Power Plant were found to have become stronger over their lifetime

In a list of walls that you’d want to stay strong, those in a nuclear reactor would be near the top. Now, researchers have found that the walls in a decommissioned power plant in Japan have not only kept their strength but have actually gotten stronger with use, thanks to a rare mineral also found in ancient Roman concrete.

Biden says “No Mas” to the Latest Caravan of Illegals

by: Brent Smith

Oh Yeah – I’m sure this is exactly what the latest migrant caravan wants to here – don’t come now.

After all the wailing about the Trump administration refusing the angelic migrants entrance into our nation, and the promise from leftists that once we take charge, you’ll all be welcome is turning out to be just another leftist lie.

And why? Well, maybe it is really that they’ll all be let in, but it’ll just take some time as the Biden people are saying. Or maybe it’s something else.

Now I’m just spit-balling here, but the dirty dems did just prove that they’ve discovered (fabricated) the means to win an election without additional illegal alien votes. And historically, if the left doesn’t need you – if you don’t or can’t further their agenda, they’ll toss you aside. Maybe that’s it.

In any event, the Biden people are asking the latest caravan not to come right now.

CityQ Better than eBike

The CityQ has four 20-inch wheels ... but no chain, belt drive or derailleur

Ebikes may indeed require less pedalling effort than regular bicycles, but most still offer little in the way of cargo capacity or protection from the elements. The CityQ is designed to provide both, along with four-wheeled stability.

No Ordinary Gravel – It’s from an Asteroid

It’s rare that gravel gets scientists so excited, but these are no ordinary rocks. They’re the samples returned to Earth by Hayabusa2 after its 5.24-billion-km round trip to asteroid Ryugu, and this is our first glimpse at them after the spacecraft landed in the Australian Outback on December 6 and its sample container was transported to Japan.

Bugatti has released a photo dump showing its nascent Bolide hypercar getting a little coy with some of its clothes off. Currently #6 on our list of the world’s most powerful cars, the 1,825-hp Bolide prototype is an epically raw rejection of luxury. read more

Rides in Electric Air Taxi Already Sold Out

The Volocopter 2X made its first manned flight over Singapore’s Marina Bay in October 2019

Germany’s Volocopter has committed to launching commercial eVTOL flights in Singapore “within the next two to three years,” and advance tickets have already sold out to early adopters eager to take the first joyrides in this electric air taxi.

The company has been very active in Singapore, where it’s done several test flights, including a high-profile manned flight late in 2019. Singapore doesn’t strike us as a market that’s crying out for air taxis, what with its very small area, well-ordered roads and terrific MRT subway system. It barely cracks the top 100 in TomTom’s list of cities ranked by traffic congestion, and we’ve never found it anywhere near as annoying getting from A to B there as in, say, Los Angeles, or Bangkok.

It does have plenty of money, though, and a solid tech research sector, and evidently several friendly government bodies, including the local aviation authority.

“Singapore is renowned for its leading role in adapting and living new technologies,” says Florian Reuter, CEO of Volocopter. “Our successful cooperation with the Economic Development Board, Ministry of Transport, and Civil Aviation Authority of Singapore on our previous flight has shown that there is no better place in Asia to launch our electric air taxi services than in Singapore. The city’s research institutes conducting R&D play an integral part in this. Topics like route validation for autonomous operations, material science, and research regarding battery technology are very important for our long-term business success.”
