CO2-neutral "fri energi" døgnet rundt overalt på jorden

[Glenn]

(Svar til dk.teknik.energi )

Vi har nu muligheden for at lave CO2-neutral "fri energi" døgnet rundt -
hele natten - og (selv meget overskyede) dage - overalt på jorden. I

Jeg vil formentlig få nogle kommentarer på denne påstand :-) Jeg ved at
energien per kvadratmeter vil være meget lavere end 1000 W/m2 midlet
over et døgn:

Anvend en varme-IR selektiv overflade (a la Stanford) med fx en
Stirlingmotor, en elektrisk generator - og to heat-pipes:

gyroscope.com: Precision Stirling Engine:

Citat: "...
Ultra Low temperature difference Stirling Engine
...
As long as one plate is warmer (about 5°c) than the other then the
engine will run.

"Magic" heat-IR selective surface:

Stanford School of Engineering. (2014, November 26). High-tech mirror
beams heat away from buildings into space. ScienceDaily:

Citat: "...
"As a result of professor Fan's work, we can now [use radiative
cooling], not only at night but counter-intuitively in the daytime as well."
...
The first part of the coating's one-two punch radiates heat-bearing
infrared light directly into space
...
This multilayered coating also acts as a highly efficient mirror,
preventing 97 percent of sunlight from striking the building and heating
it up
...
Together, the radiation and reflection make the photonic radiative
cooler nearly 9 degrees Fahrenheit [5 °C] cooler than the surrounding
air during the day. The multilayered material is just 1.8 microns thick,
thinner than the thinnest aluminum foil. It is made of seven layers of
silicon dioxide and hafnium oxide on top of a thin layer of silver.
These layers are not a uniform thickness, but are instead engineered to
create a new material. Its internal structure is tuned to radiate
infrared rays at a frequency that lets them pass into space without
warming the air near the building.

Hvor får man en rigtig stirling motor, man kunne montere på en
generator?

Hej Michael

Denne hybridbil har en større (effektmæssigt) Stirlingmotor:

Hybridbil der drives af en Stirlingmotor (se i kilderne):
