The first version of my radiation detector is being sent to people all over the world and I've gotten very good feedback. Now I need to make a second version with Bluetooth and gamma spectroscopy. And a longer battery life. And higher max range. And higher sensitivity. And a bigger screen, probably. https://www.bettergeiger.com

I have, but personally I prefer to pay something in the ballpark of market rate.

$495 an hour for this is insane

Sounds interesting! If I may ask out of curiosity:

Why OLED?

Why this QR thing and not Bluetooth, or is it both?

Is it storing long-term data or just while battery is on?

I manufacture and sell one unique product. I started with direct sales, doing okay, but it was clear that Amazon is where the real action is, so I tried to sell there. Getting the listing up was a slow and painful experience due to horrible seller service (this is typical). Finally it's listed. Around 15% of revenue is fees. That's with me doing my own fulfillment! Hardly any sales at first, so I had no choice but to advertise. It looks like another 15% of revenue will end up going to amazon ads. Amazon will probably end up making more money than me, just for being the middle man. That's if I'm lucky, because sales are still just a trickle, and I'll probably have to up my ad spend to get any real traction. It seems like the system is designed to put comparable products competing against each other and the one that rises to the top is he one that Amazon can squeeze the most blood out of, unrelated to what the user might benefit from.

Your numbers for beef are absurdly wrong. Reality is closer to 2000 gallons per pound, or roughly 0.5 calories per gallon. Chicken is about 4x less. Grains are roughly an order of magnitude less. As a country the USA consumes dramatically more meat than necessary, cutting even a little would have a massive impact on water consumption.

Yes most of the water use to produce beef is indirect, in growing the feed. If beef is taxed to consumers it will reduce demand, which will reduce the demand for feed, which will reduce the consumption of water. Decreasing the demand for cereal will decrease its cost, not increase it.

Most water use is for agriculture. Most agricultural water use is for meat. Beef is by far the least efficient way to turn water (and other stuff) into protein. I propose we tax meat nationwide according to its water use, instead of dreaming up unrealistic and unnecessary megaprojects.

No photos... Come on.

The cost of renewables increase as their fraction of the overall mix increases, i.e. When the fluctuations become harder to be balanced by other sources, and more and more energy storage is needed to handle the fluctuations. Energy storage in that large of a scale is very costly and impractical. In reality what will happen is more and more natural gas usage, which is a bad thing.

Here we are, talking about the waste, even though the waste is pretty easy to deal with. That's what it accomplished.

I already answered hundreds of questions on reddit but I bet the ones I get here will be more challenging. :)
