RE: Basics of Transformer Design

garvitgugnani — Thu, 29 Oct 2026 09:59:45 GMT

Hey kkazem, loved your succinct insights in this blog. Very clear understanding.

I run a manufacturing company of instrument transformers up to 33KV. I want love to connect with you. Please check your DMs. I have even sent you a request.

RE: MIT Develops a Potentially Safer Battery for Internal Medical Devices

Wild, I wonder what the failure rate is on current consumable items such as this to warrant this research? My understanding is that most capsules were some form of glass for this reason, but of course digestive systems can be different and not necessarily passed through.

I wonder how they compare to super-capactors?

If you're happy to build your house next to it then go for it.

RE: ANDRITZ is Replacing the Old Hickory Dam Equipment

This is awesome. This equipment was designed and built back when energy was cheap and small inefficiencies - like concentricity - were acceptable losses.

I did chuckle at the change in power factor rating. On the generation side, kVA is what matters - because it's really all about amperes. kW is a marketing number - calculated based on NEMA MG-1 in the US. Almost pure fiction - unless your generator is engine limited (lacks the horsepower to carry the true (real) power load). Engine limited generators are not the norm because they come with a host of other issues (high voltage dip, slow recovery times, no overload capability, etc.) Hydropower only experiences this during times of low water.

Based upon recent flooding patterns, the US needs to go through Kentucky and create a similar water flow control system. Plus we can always use more power sources.

RE: Farmers in Egypt Use Solar Panels to Grow Crops

It would be nice to see the long term plan for sustainability of these installations. Witnessing all the issues with replacing aging infrastructure makes me worry about large scale deployments of this type in harsh environments.

We have a small 50kW agrivoltaics demonstrator as part of the solar farm here at the uni.

Looks like we are growing deer under the main arrays [emoticon:c4563cd7d5574777a71c318021cbbcc8]

Great progress since 1965, excited to see it in the void.

Unbelievable! Anything related to photonic processing?

RE: AI Data Centers Require a Lot of Water, Where Does It Go?

DAB — Sun, 09 Aug 2026 19:48:44 GMT

If I was an enterprising company, I would integrate the data centers into a salt water desalination plant using the heat from the chips to heat the water and then condense fresh water from the evaporated steam. That way you could more easily get local governments to invite you in to build your data centers.

RE: Honeycomb-Shaped 3D PV Modules Could Generate More Electricity Than Flat Panels

We can only hope that this technology makes it to market.

RE: Ancient Cities Are Now Using Solar Panels in Roof Tiles

beacon_dave — Sun, 12 Jul 2026 18:54:16 GMT

Looks like they have gone with individual tiles rather than grouping several tiles into a more traditional sized solar panel.

Lots of connections !

RE: Ancient Cities Are Now Using Solar Panels in Roof Tiles

DAB — Sun, 12 Jul 2026 18:24:17 GMT

This approach makes sense.

You greatly extend the life of the roof and provide local power.

win win.

RE: Researchers Develop Water Battery That Can Be Safely Disposed

DAB — Thu, 21 May 2026 20:45:02 GMT

I am not sure that you can make a cost effective battery with this technology.

If it is not as good as the Lithium battery and it does not last as long as a Lithium battery, where is the market?
