My new Book launch “The Story of Light: Wonder World of LEDs”.

Cosmic is a San Francisco-based startup that is building tiny houses. The company’s founder, Sasha Jokic, believes that these houses can help fill the gap by creating new rentals. In addition, Cosmic’s houses are designed to be highly energy-efficient — helping to reduce carbon emissions from the housing sector. Cosmic…

70-year-old quantum prediction comes true, as something is created from nothing Can we really create matter from nothing? After all we know that the law of conservation of matter and energy rules out this possibility. …

Great ideas look very simple in hindsight, and you wonder why no one thought of it earlier. SWEL (Sea Wave Energy Ltd. …

Every system design starts with an idea that grows from concept to research and analysis, and as it takes form, there is usually a consistent flow of design until hardware is needed (Fig.1). Getting the right board is sometimes a difficult proposition. You might find exactly the evaluation kit you…

We do have fully solar powered houses and buildings but here is a live high rise building project under implementation which will be fully powered by its façade solar panels which don’t in any way look like the normal shiny solar panels at all. They are perfectly aesthetically pleasing and…

I wrote about the Lilium electric airplane in November 2021 and you can read it here. Since then, the company is making a steady progress and they participated in the Farnborough International Airshow held recently. As a matter of fact, there are now a range of contenders in the pipeline…

In the solar domain there is ongoing research all the time to increase the efficiency on the one hand and to make the cells cheaper on the other. A third factor is to reduce the carbon footprint in production of solar cells. Most solar cells are silicon based. A lesser-known…

Solar energy is one of the cleanest and most abundant energies available freely to mankind and one of the most promising for the long-term adoption, in increasing measure, in practically all applications. There are still two issues that need to be further researched and better products developed. The issues are: …

xcluma 4000W 220V AC SCR Voltage Regulator Dimmer Electric Motor Speed Controller In most lab experiments and so many electronics projects as well as hobby work we need a variable voltage source. Now, most sources like the AC programmable or non programmable power source or a variac are simply too…
