"We are rolling out technology that can beat the price of fossil fuels and also not make the CO2 emissions," Bill Gross, Heliogen's founder and CEO, told CNN Business. "And that's really the holy grail."
Heliogen, which is also backed by billionaire Los Angeles Times owner Patrick Soon-Shiong, believes the patented technology will be able to dramatically reduce greenhouse gas emissions from industry.

Not the first "miracle" energy tech to be announced over the last 40 years.

Bottom line with solar is a theoretical max of about 1KW per square meter. That's high noon at Death Valley at 100% efficiency. Goes downhill rapidly from there.

Solar reflectors have been made for years.

Read about Ivan ho to understand why they are a bad idea in the 21st century

Old school silicon has so many advantages

If you wish to discuss the fundamental technical basis of the tech, be my guest. But not the inflammatory or politically sensitive topics.

It would work in a band around the equator that gets enough year round energy and plenty of cloud free days. While Calgary has the most sunny days in all of Canada, the amount of energy within that sun drops 90% in the winter months. These people seem to think the world’s center is Los Angeles and if it works there it’ll work anywhere. The tech seems very limited. You could “make” cement and steal using it in the middle of the gobi desert, but then what? Transport it via diesel truck to where it’s useful. Perfect.

Why was my post deleted? The entire subject in the OP is political?

Using heliostats for CSP definitely isn't new. Ivanpah is the ultimate White Elephant of this tech. The cost of a nuclear plant with a fraction of the output and the complete inability to function as a baseload generator. Trying to force solar into roles where its simply not suited has been going on for ages.

Plenty of people profit on it however.

Yes, yes they do.

That's how you know they have nothing special. If they had a breakthrough they would simply start building them and watch the money flow in. When they go all buzzword they are needing "alternative funding" to get money to their account.

So you guys are saying this is nothing groundbreakign or exciting? Just asking I know little about this stuff.

First, it would be of benefit for you to look up Ivanpah. You can start with the Wiki on it:
https://en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility

The idea of using heliostats to concentrate solar energy at a receptor, be it a molten salt or some other medium to spin a steam turbine, isn't new. The idea that you can use the heat in a process heat application is a slightly different twist on it, but still runs into the inherent issue of intermittency associated with solar. Steel mills, concrete factories...etc Industrial operations that utilize process heat run constantly. Becoming weather-dependant isn't a viable business model, even if it makes the process heat free. And it wouldn't be as easy as using it as a fuel saving device for existing applications because of the fundamental design differences in how one harnesses CSP versus a traditional fossil-powered furnace.

There have been a number of different ideas floating around as to how to replace fossil fuels in industrial applications that utilize a furnace, such as making steel. One that comes closest to maintaining existing structures and models would be the most likely to succeed, such as using hydrogen: https://www.sei.org/publications/hydrogen-steelmaking/

There's a lot of hype about VRE and fitting it into roles where it is ill-equipped. Separating these wild fantasies from what's real and obtainable within a reasonable timeframe can be frustrating when you are bombarded with propaganda promising everything from solar-based energy independence in Winnipeg to wind turbines providing baseload if we only ran cables the entire length of the Atlantic wink
