According to them, their prototype does use 20Wh per liter and produces 0.3 liters per hour. It’s not 20Wh per 0.3 liters. That’s USB charger level of electricity, my 100 EUR foldable solar charger produces more on a good day. The interest

The device needs power, but solar is not a requirement. But you’re correct, nothing is ever absolutely maintenance free, especially if it contains moving parts. However, their envisioned use case is not “helicopterdump across the desert” bu

Even devices that use Reverse Osmosis usually don't aim to catch all contaminants in the filter - they use a membrane/filter to separate the clean water output from a waste water stream that contains the contaminants/salts in

This device was discussed earlier on HN and that article goes a little further into the design decisions for the device. (1) The focus is not efficiency or volume. It's compact, portable, robust, maintenance free. No filters, no high p

You could guesstimate by checking the IP address - blocks assigned to residential users are likely humans, blocks assigned to cloud providers etc. likely bots.

I’m currently on vacation and the hotel breakfast buffet has a gluten free bread option. Granted, it’s prepackaged toast, but I’d say it’s better than hungry.

If your argument would hold true, that load would already be taken by coal power plants which fill the same role. Gas peaker plants are substantially more expensive to operate per kWh of electricity produced than base load plants. They fill

by Xylakant 5y ago
That’s not how base load/peak load works. You can’t just increase the base power output - that would lead to too much more electricity in the network, you need to balance the energy provided with the energy used. That’s exactly why you

Gas in electricity production is mostly not used for base load - it’s peaker plants that need to spin up and adjust load within minutes. Nuclear replaces coal, not gas in most use cases. Heat pumps are subsidized in germany. And if you want

One could also ask for the US to replace their car centric mobility with bikes and trains to save oil. It’s spring right now, they’ve got 6 month until winter rolls around, time to be used wisely. Our apartment complex uses a small central

Our apartment complex uses a gas micro power plant to produce electricity and uses the waste heat for heating/warm water. It’s a building of its own on a compound with 20 or so apartment buildings. Replacing that with a heat pump will

To make the point a little clearer - natural gas is an important resource for the chemical industry, for example input to the Haber-Bosch synthesis of Ammonia. The Hydrogen used is mostly gained from methane, that is natural gas. Ammonia is

I'm not complaining - I'm pointing out that leaking memory is considered "safe" in the rust memory model to the point where there is a safe method in the stdlib to do so.

What about the people that get pushed off those large platforms through constant abuse, threats and trolling? Do their opinions not matter? Or more general: at what point does an utterance stop being an opinion and start being assault?

Rust as a language does not protect against memory leaks - std::mem::forget even explicitly does so. Generally garbage collected languages do, so trading go for rust increases the risk of having memory leaks.

The NATO has no power to restrict actions of its members - it can just decide not to support them, which is common. Any action unilaterally taken by a member state or a group of member states that is not explicitly adopted by the NATO counc

Washing machines consist mainly of materials that are easily recycled and very economical to do so. Metals, mainly, in a large package. Pure copper in the motor. All of which can be recycled to build a new washing machine.

Washing machines pull considerable power and the power scales with the water usage: They use warm water, either from a tap or using a heating element. Heating water is energy intensive, and the hot water quite literally goes down the drain.
