It's so rare to actually see a new battery tech exit the lab and enter production. Always seems like there's 10,000 new up and coming breakthroughs in battery technology, but none ever leave the workbench....
I found these kind of cool as an idea, as they can be added rather easily to existing cities and provide some greenery without taking up space, while providing shade:...
According to MIT, this technology works even at small scale, with one the size of a suitcase able to desalinate 6 litres per hour, and only needing to be serviced every few years....
I wanted to park my bikes - or depending on the Season - my Renault Twizy somewhat protected and easy accessible....
This is quite exciting in that it removes plastic waste. I see no reason why different companies can't make different shape ones to maintain their lock-in. I expect a knock-off market to pop-up, but that exists with plastic pods too. It's a step in the right direction at least.
This is an industrial designed exercise bike from Lithuania that can store 2KWh of electricity generated by your own exercise.
This seems like a great technology to build resiliency and redundancy in a community, especially for places where cell service is spotty, or in the odd event where normal lines of communication are blocked....

A simple mix of two cheap salts, Sodium Sulfate and Table Salt (Sodium Chloride) dissolved in boiling water can create a really useful Phase Change Material that has a melting point of 18c (65f) which allows it to be recharged back into it's cooling state simply by putting it in a basement and can then be used as a cooling...
Thought of you fine folks when I came across this article on aussie.zone

Solar panels have traditionally been made with silicon, over which China has had majority market control. Eager to limit China's stranglehold over the solar market, countries have been searching for a different way to harness the sun. Now, Japanese engineers "believe they have found one in a type of solar cell that looks and...
Researchers in China have reportedly developed a new technology similar to hydropanels for harvesting water out of thin air that is powered by energy from the sun. The device could be especially useful in dry, arid areas where water — but not sunlight — is hard to come by....
