I hear that experiments using this element promise that soon it will be commercially used to produce unlimited power from small doses of solar radiation reliably cheaply and most of all, it even transmits power to wherever you want to use it without wires or costly transmission lines.

Doing some digging on rectennas to see if any progress has been made in the field, perhaps they could be used to cool conventional solar panels or perhaps other heat harvesting. At the rate silicon and perovskites solar cells are developing and their costs dropping, optical rectennas don't look viable for a long time and don't appear to be theoretically much more efficient than conventional types. Maybe for receiving space generated solar power in the microwave range, but that idea doesn't appear feasible when compared with the progress being made in terrestrial installations, energy storage and HVDC grid transport.


Will Rectenna Solar Cells Be Practical?

Australia has lots of iron ore and lots of sunshine in about the same place and could be the green steel capital of the world using this technology. Why send iron ore to China when they can use hydrogen and heat from this process to make iron sponge and carbon free green steel in electric furnaces.

All cities are surrounded by industrial parks and suburbs with house and garage rooftops. Consumer solar panels or solar integrated roofing tiles along with home energy storage will give those hooked up to the grid more power as both distributed producers and storage close to where the power is used. This will take tremendous loads off the grid as more power is produced and stored locally using a distributed grid of home solar generation, and storage using home battery banks and plugged in EVs. There will still be grid scale solar, wind and other power production, energy storage and HVDC power transport, but less of it will be needed with a lot of domestic production and storage around the areas of heaviest use.

Every 1000 suburban homes that can break even by producing and storing their own power, equals a megawatt of power. With an EV and a heat pump most people with a suburban home could achieve energy independence using solar and home energy storage with excess sent onto the grid or have a greatly reduced grid demand.


Why Solar Panels Aren’t Unfair or a Scam
There’s concerns that homes with solar panels are reducing their utility bills at the expense of their neighbors without solar panels. The phenomenon is referred to as “cost shifting”: the idea that the credits utilities pay to solar homes for the solar energy they produce ultimately results in higher bills for customers without solar panels. This has had major implications on public policy…for better or worse. Is the solar energy cost shift real?

Why The EV Industry Is Betting On This Lithium Mining Breakthrough

168,671 views Jun 5, 2023 #CNBC
A suite of new, but largely unproven, technologies known as direct lithium extraction could revolutionize lithium mining from brine, making it more efficient and sustainable and eliminating the need for large evaporation ponds. A number of companies including EnergyX, Lilac Solutions, and Standard Lithium are entering the DLE market and getting ready for commercial implementation across South America and the U.S., while automakers like BMW, GM and Ford are investing.

Chapters:
00:00 — Introduction
01:55 — The need for DLE
04:17 — Different approaches
10:50 — Road to commercialization

CORRECTION (June 5, 2023): At 12:16 in the video we state that Bolivia was previously considering using DLE technology from both EnergyX and Lilac Solutions. In fact, the Bolivian government is

A potentially disruptive technology right under our feet and it could upset wind and solar while using existing fossil fuel power stations and their grid infrastructure.

"Walking" anchor and plasma drill promise cheap, deep geothermal power

Slovakia's GA Drilling has demonstrated a pair of new technologies it says could unlock geothermal power generation more or less anywhere on the planet. Anchorbit and Plasmabit promise much faster and cheaper drilling into hot rock 10 km (6 miles) underground.
