Construction of a simple HHO generator, made of stainless steel washers and a water bottle. An hydrogen generator, like this one, uses electricity from your a battery to split water into hydrogen and oxygen gasses.
In the Russian metropolis, a former power station was transformed into a modern cultural centre with a solar roof. Sunovation manufactured the modules according to the architect’s designs.
The LCLS-II X-ray laser is 10,000 times brighter than its predecessor and fires 8,000 times faster.
A Norwegian company developed a floating wind power system that provides the energy of 25 traditional wind turbines at roughly half the price.
A DIY microscope made out of LEGO bricks and smartphone lenses could be a powerful learning tool, teaching children not only how to use microscopes, but also how they work.
Seeing is learning: Microscopes are an essential scientific tool, right up there with bunsen burners and petri dishes, which means they’re also essential to any child’s science education.
But even when young people have access to microscopes, they’re often only taught how to use the instruments — put a slide here, look through there — and not how they actually work.
Militaries around the world are making fast advances in AI weaponry. Learn why many see this as a threat to human values.
We have just checked the Tesla estimated delivery times (for new orders) of all four electric car models available in the U.S.
There are some interesting findings, as the hectic extension of delivery times has slowed down, and in some cases, even stopped or reversed. The prices have also remained unchanged since November 12.
Let’s start with the Model 3. The queue for the entry-level RWD version with an LFP battery appears to decrease as the estimated delivery time is the same as over one and a half months ago (June or October, depending on the wheel option). The Long Range AWD and Performance versions moved up a bit — to March and February. As we can see, the higher price/higher margin versions are prioritized (it will be common for all models).
The U.S. and China are vying to control the world’s digital infrastructure, and the new “Peace Cable” has Europe caught in the middle.
Indeed, nothing like this has ever been attempted in space before ensuring that we hold our breaths each time the JWTS embarks on the next steps of its six-month journey to fully transform into its final configuration and begin its science mission. Now, NASA is reporting that the telescope just successfully completed another step in its impressive transformation.
“With the successful extension of Webb’s second sunshield mid-boom, the observatory has passed another critical deployment milestone. Webb’s sunshield now resembles its full, kite-shaped form in space,” said NASA in a statement.
Let there be darkness.
That is the potential catchphrase for those that are concerned about nighttime light pollution.
More formerly known as Artificial Light At Night (ALAN), there is an ongoing bruhaha that our modern way of living is generating way too much light during the evening darkness. It is an ongoing issue and the amount of such pollution is likely to keep on increasing due to further industrialization and expansion of societies into additional geographical areas.
