I'd imagine a lot of places where software is part of a safety critical system also come with physical fail safes. An example being burst plates on pressure vessels, if the software that controls pressurization spasms and causes an ove

Rock isn't necessarily airtight more so in mines. A fractured host material for the ore is very desirable as it means less explosives and higher ore production numbers.

That data is the secret sauce for mining and oil and gas companies. Them giving it away would be like Facebook giving away their datasets.

Right but my point is if you're premeditating the theft to the point where you've studied the manuals/practiced in flight simulators then a key isn't going to be the thing stopping you. I mean will that person realistica

It's not like the engine start procedure on one of those things is a turnkey solution. The amount of domain knowledge needed serves as a form of soft security.

Atmospheric concentrations are low so you need to harvest a lot of air. To put in context the earth has ~2E9 km^3 air, if you wanted to process every cubic meter of air in the world once in 10 years you'd have a system that could proce

Not an issue if you have low abandonment of subscribers but an issue if everyone exchanges papers that way. You get a lot of value out of being able to search all the journals in one place. Also what happens if the author is dead or has dro

The article says that Australia has 14% of global reserves not that they're only mining 14% of what they have. We've also found all the easy stuff already, the cost of exploration will only increase over time since the good stuff

You should look into building elements with micro encapsulated phase change materials. They're becoming popular nowadays, and you can find ceiling panels and wall panels from commericals suppliers. The pcm melts during the day cooling

That's true only of devices that don't convert the energy into work(motors), light(LEDs) or other voltages(transformers). All other electronics convert all the power into heat. Basically any computer is a heater that so happens is

Dealing with cold energy(coolth) storage whether it's in ice or chilled water is tricky mostly because of the capital cost involved with adding a storage system that can only do one thing, namely store cold. They're great for spec

Cold energy storage has always had the problem of utilization and capital cost. You need to buy the storage system and then that storage system may only be useful for 3-6 months of the year during 6 hours of the day. From a thermal efficien

Ish, solar thermal has its own set of problems and limitations; they don't work during cloudy weather and the storing the thermal energy is tricky because you need a lot of high quality thermal mass
