Remember the StarTrek saying: “the acquisition of wealth is no longer the driving force in our lives, we work to better ourselves and the rest of humanity” just one of many examples: The world was not allowed to make longer-lasting […]
most important: use the WatchPower version that comes on CD with the solar charge controller, as newer or older versions might not be working (incompatible, changes in protocol etc) it might wise to use a galvanic isolator (even the shielding […]
easiest and best fire protection: have the cells SPACED apart, so one cell CAN NOT heat up surrounding cells put the battery pack in as-thick-as possible metal box then put plastic bag of sand on top of pack (better than […]
update: 2024-04: system running well fastest AMD with integrated GPU would be: Ryzen 7 8700G (search bundle on ebay) the Ryzen 7 has more cores, so single core wise the CPUs are close to each other, multicore the 7 should […]
Even managed to run this system ONLY with SOLAR POWER from March to November (but not winter X-D) Of course RISC(V/ARM) based (mobile) gaming systems would be those that use the least amount of power per frame 😀 But it […]
xmlrpc.php is only in use, if the user uses the wordpress app. if the app is not used, it would be wise to disable this file, because it is frequent target of brute force (trying out a billion passwords) attacks, […]
what is great about books vs blogs? (+) paper books don’t need electricity and hightech to function. energy grid and tcp networks (up to now) have worked pretty reliably, but at any given day, a massive solar flare or a […]

Bitcoin’s annual electricity consumption adds up to 45.8 TWh (45.800.000.000 kWh) The corresponding annual carbon emissions range from 22.0 to 22.9 MtCO2 This level sits between the levels produced by the nations of Jordan and Sri Lanka src: https://www.sciencedirect.com/science/article/pii/S2542435119302557 a […]
How does it work? nicely explained by an orio cookie 😉 MASSIVELY POWERFULL RC CAR! (First Porsche on Hydrogen, is a TOY CAR!)

apologize! games = windows, still ? (although there are 6000 steam games running on linux) the very first “Open Source GPU” is in the making: https://www.crowdsupply.com/libre-risc-v/m-class “The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the bedrock. […]
every once and a while… laptops and notebooks run out of battery… and when one manages to plug them in just 1% before stalling… the wifi on Debian might already be in hibernation and hardware on off does not help […]
Not a lot of humans on this planet manage to entertain and educate at the same time. ElectroBOOM does it nicely, one can find him like that: it is just outstanding funny and entertaining… X-D singing with tesla coils: this […]
how can everyone help? Musk: talk about it! 🙂 spread the news! set the focus! cognitive disconnectedness between governments and science: the non-sustainability mess Let’s face it… the fossil fuel powered steam engine economy … once started… is very hard […]
as far as i understood the “string theory” and also Einstein’s Theory is that on the smallest building blocks Matter = is actually = Energy, in “string theory” this energy is resembled as a vibrating string, if it vibrates in […]
Update: USB 3.0 can interfere with WiFi “USB 3.0 has a 5Gbps signaling rate. The USB 3.0 specification requires USB 3.0 data to be scrambled and it requires spread-spectrum. The noise from USB 3.0 data spectrum can be high (in […]
these are all challenges that need to be overcome… and they can be overcome… with “good enough” energy storage systems. how can everyone help build the city on Mars? Musk: talk about it! 🙂 write about it! spread the news! […]
checkout the space weather today 🙂 “Schwabe cycle, is a nearly periodic 11-year change in the Sun’s activity” (src) but the sun’s particles ALSO shield from even more outer space radiation BUT the sun is ALSO protecting Earth & Mars […]
We all want RELIABLE technology to serve mankind – not pollute the planet and the oceans. For this to play out right – it is important to ONLY buy HIQH QUALITY products – that are hopefully manufacturerd IN YOUR COUNTRY […]
“You can be profitable and green” An expert at Gerson Lehrman Group wrote that, given today’s electricity transmission losses of about 7% and utility-size gas-fired power stations efficiency of 33–48%, the Bloom Energy Server is up to twice as efficient […]

Some people think it is ridiculous to measure the power consumption of computers. Imho it is important for servers but also if workstation uses 50 Watts idle or 10 can also make a difference when it is used a lot […]
200Watt WHEN IDLE ! 300Watt under Full CPU Load. WTF? Quiet a lot 😀 Get a GIADA F-300 and reduce it (including Screent) to 50Watts!
200w when idle 300w when CPU busy 12w in stanbby 3-5w when “off”
Uploaded on Dec 25, 2008 http://www.panoramio.com/user/1780803 Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. This cavity may take the form of a pre-existing bubble, or may be generated […]
“Rechargeable lithium–air (O2) batteries are receiving intense interest because their high theoretical specific energy exceeds that of lithium-ion batteries. If the Li–O2 battery is ever to succeed, highly reversible formation/decomposition of Li2O2 must take place at the cathode on cycling. […]
