Large power transformers have efficiencies in the 98-99.75% range. I don't doubt switch mode could be smaller and cheaper up to some size, but I am struggling to see transformers l…

Are you saying large Transformers 1 mva, 10 mva, 100 mva, 500 mva are obsolete and should be replaced by switched mode power supplies? What mva is the threshold?

like you I hope I'm as present in my senior years! Female friends have entertaining stories about encounters with him from 17 years ago when he was 77!

what else have envy and greed driven? What would the world look like without those inate human emotions? It might be a simpler place but potentially the worst of history could have…

Wannabe's is pretty harsh for a group of people that started first and achieved their goals second. Wannabe's never do the thing. They don't seriously try to do it. I have no reaso…

Are there cities with land that isn't expensive?

In desireable locations the land cost is often more than the construction cost, so splitting that land cost across multiple dwellings makes them more affordable. Sure the cost per …

I'm looking to sell my f150 in to these high used car prices and get an electric pickup for hauling my snowmobile. Self driving doesn't interest me at all. Cyber truck delivery is …

Just to be clear vxworks is not bsd based that I could tell from Wikipedia. I work with Schneider electric plcs and sometimes vxworks errors bubble up.

I didn't realize that hydrogen is/will be commonly transported as NH3 ammonia before its end-use. I'm starting to see lots of articles about Ammonia as the transportable energy den…

It becomes an easy decision to get an electric f150 when gas costs $8 a gallon because of carbon taxes and a full charge is only a couple bucks

Both you and and animats are describing the same thing, brushless synchronous machine, which exists for long time.

Thanks for the great posts. Have you seen any numbers for the life expectancy of grid connected batteries? I heard A solar project in Hawaii expects to replace the batteries every …

Nuclear + renewables = 0 carbon and a consistent reliable base load ... sounds ideal?

People are attacking texas' less interconnected system for being "independent" and others are pointing out more interconnections from places with no power to spare would not have h…

Underground costs about 10x as much as overhead.

The intertie from BC to Washington is 3150 MW from north to south.

Put the food outside?

The paper suggests solar thermal and wind plus gas peakers. So the overbuilt point from the parent stands.

So bringing up battery storage on an article about a blackout caused by a multi day storm might lead some people to believe that batteries would make a difference in this situation…

Electrical engineers wouldn't build a power line to Texas with a capacity of 5000 MW and then put intertie hardware such as phase shifters or ac-dc-ac converter with capacity of 10…

Not for batteries since a battery that can deliver 17 GW for an hour is much smaller than one that can deliver 17 GW for a week. Usually grid connections are measured in power sinc…

Or somebody cheaper can generate since they didn't bother building their plants to withstand low temperatures so the more expensive plants to run go out of business or lose that ex…
