This is a great idea for a renewable power source. We've come a long way as far as solar, wind, and other renewable energy sources are concerned but we also have to acknowledge that it's not possible for these sources to be put up in cities because of space and other design issues. This could be of great use for electric cars too.
This is pretty cool and can really speed up how houses and buildings are built. The robot looks like it's capable of laying the bricks don with great accuracy too. In a decade or so. it's even possible that all construction work is done by robots instead of human beings. That's probably faster and more cost-efficient too.
In this day and age, it's really surprising to know that 38% of rural Americans don't have access to broadband. Almost everyone is on the internet now posting mostly inane things but there's a lot of useful and important information to be had too. This video was published in 2017 though so maybe things have improved since then?
When phones with cameras first came out, I was really glad how it made it easier to capture moments and memories. These days though, I found myself more and more turned off by the idea of always having to take pictures. I think this shift in our culture is a permanent one -- people who choose to take photos of events and sights instead of actually seeing it and living in the moment.
I think this is a technology that can be helpful not just in our efforts to terraform Mars but also helping our own planet. The way things are going, we may need machines that can produce oxygen here especially with carbon emissions not slowing down as much as they should and the polar caps most likely meting within our lifetimes.
If the use of battery-powered airplanes for short distance takes off, this can be a real game-changer for airline companies and the airplane manufacturers. This can also make traveling more affordable and eco-friendly. I initially thought they'd focus more on private airplanes and stuff but I'm surprised that they're already working on one that can seat 150 people.
