That is so cool! Did a bit of searching, this looks like like a good place to start. I’m not visually impaired, but am still very interested in learning to echolocate!

Airbags are not forbidden in aircraft. They just haven’t been considered to offer enough safety benfit for their weight and cost in most cases. That is starting to change though, and airbags integrated into aircraft seatbelts are becoming more common. They can be found in first class in a number of commercial aircraft, and are sold to be retrofitted into private planes.

There are many reasons I doubt this car will make it into commercial production, but the airbags will be OK.
Eating a dictionary to improve your vocabulary would be equally effective to that theory, and for many of the same reasons. (As far as information transfer is concerned)
Very true. Unfortunately, this process just pulls gold from dilute sources and gathers it into nuggets, from small ones to very very large. No gold is being made new though, that would be great.
Well, that is the amount gold that is mined or recycled every year that is used in electronics. The thing is though, a lot of the gold used in electronics is never recovered. So a considerable amount of the gold used in electronics is removed from from circulation in a way the gold in jewelry or bullion or coins isn’t. It isn’t the primary driver of gold’s price increase, but it is a significant factor.
Gold prices have risen steadily for a long time, partly because of its use in electronics. Over $2500/ounce now. But another quirk of gold is the ease with which we can make very thin coatings of it over other materials, sometimes only a few atoms thick. So it is commonly used, but in very very small amounts per device.
But remember, electric motors also require next to no maintenance and can last for many years of runtime. Pros and cons.
Sure, to get them to speak in unison. They did all read from the same script though. It wouldn’t be as viscerally creepy without the editing, but I would say the situation is as bad as the video makes it seem.
Probably worse for Barbra than the picture is this phenomenon being named after her. I was familiar with the the Streisand Effect and who the name came from, but didn’t know the backstory and hadn’t seen her house.
For anyone curious.
Maybe that was literally the case, he apparently had mercury poisoning at around the same time.
It’s starting to sound like a retelling of the old lady who swallowed the fly.
Someone needs to invite /u/Poem_for_your_sprog to Lemmy.
Well, I just said carbon fiber, but to be more exact it is forged carbon SMC, so yeah, careful engineering involved. Same stuff Lamborghini is using for some structural components, so probably fairly fit to purpose.
Well, it has a carbon fiber frame with a crumple zone in the front. They are going to put it through 3rd party safety testing. It won’t be as safe as a big SUV, sure, but I think it will be safer than an ebike. It also protects you from weather and has 35 cubic feet of storage in the back. I think ebikes are great too, but this does have more of the advantages of a car.
The benefits increase as the efficiency of the car increases though, check out Aptera. They say they get 10 miles per kwh, and they have a lot of surface area for panels. Enough that in ideal conditions they say they get 40 miles per day from solar. It is a bit different looking though.
Growing crops to make ethanol is not particulatly green. In fact, in most existing production loops we would be better off environmentally to just burn pure gasoline than produce the ethanol to mix into it, unfortunately. Too much water, too many tractors and trucks, and way too much electricity into ethanol production to be worth what we get out of it. And the bit of carbon the crops sequester doesn’t overcome it. Electric vehicles are by far the greenest option right now.
This is misleading, billionaires have been paying effectively lower taxes for many many years. They just had to be more creative about it before now.
This is ridiculous. There are practically no goods that would support the cost of hypersonic intercontinental rocket delivery, it would viewed as an unacceptable safety and security risk for any receiving area, and would be ludicrously bad for the environment and climate.
It won’t have started getting closer again before the Milky Way collides with the Adromeda galaxy in 5 Billion years, so it and anything we send on a similar path isn’t coming back.
TIL! I had never heard the typhoon was used for both tornados and hurricanes in China, had just heard of their Typhoon rating sytem that seems to apply more to what would be called a hurricane in the states.
But the storm in the article was not a tornado. The 3 people who were pulled from their homes lived in a high rise, and had large windows that failed in the wind, and they were blown out.
It looks cool, but that is a horrible handle. You want it to be wood or plastic so it dampens vibrations as much as it can, and smooth so one hand can slide down the handle from near the head to your other hand at the end as you swing. A couple minutes breaking up concrete with that and your hands would be numb, tingly, and probably bloody. Gloves would help, but using this will always suck.
