There's a lot of metallurgical coal necessary for the construction of certain high-grade steels, such as those you'd find in wind turbines. Similarly, try and make a PV solar cell without coal in the value chain. You can't (

I imagine "most places" refers to most places on land, which is less than 20% of the range of where plants grow. Ocean-based plantlife is the workhorse on this planet, and I would argue that the lion's share is absolutely co

This strategy, to get rid of some sunlight, doesn't fix our problem with CO2. In fact, it's likely to make the problem worse. Our planet has two primary natural methods for lowering atmospheric CO2. One, natural weathering, is n

I'm surprised they neglected a fifth theory- the moon impacted the Earth in an almost tangential, glancing blow. Liquefied rock from the impact event spread over both planetoids, making the core of the moon completely different from it

An interesting theory, but there'd be the following complications: • Job websites are, for some companies first and foremost, a signal to the investment community. Hey look, series A, and now we have these 12 job listings open. Meant

Epilogue from the excellent but dated documentary on the site: https://en.wikipedia.org/wiki/Hunter_Scott did get the captain exonerated. He is now (or at least recently) a naval aviator. No word of any movie yet.

Did the company that inspired you suddenly stop being interested in you, even if you had a proof of concept? The profit motive means technology works as follows, particularly in health care: if you can build it and corner a healthy market,

I'm fuzzy on why your wife would become a stay-at-home mom when your cost of living would at least double. Not like there aren't plenty of nonprofits that underpay in the bay (every little bit helps). If you can't keep your

Amazed how many replies the stork comment got. First off, I agree that the backseat was exceptionally roomy for a 4-door coupe. For adults. Once you have your first, you realize very quickly that babies come with a LOT of stuff. The first

I predict in the coming years we'll start referring to fructose as "bad sugar" and glucose/dextrose as "good sugar". Sucrose, being a 50/50 compound of the two, thus inherits "bad sugar" from the

Far more cost-effective would have been to skip the battery and just put a cheap chinese pure-sine-wave grid-tie inverter to bridge between the wall outlet and the panel. It's simple- it has a 110V line cord and plugs into the outlet,

Contrary to the article's assertions, the main sticking point is not a low-cost catalyst to convert CO2 + H2 to CH4. The main sticking point is the fact that CH4 can come from myriad other sources far far less expensively (some of them
