EEVblog 1637- Solar Freakin Space Mirrors - Reflect Orbital DEBUNKED

(1/10) > >>

EEVblog:
Reflect Orbital wants to put reflecting mirrors in space to sell sunlight to solar farms after dark. The numbers work out exactly as you expect them to. It's Solar Freakin' Space Mirror time!

00:00 - Reflect Orbital, Sunlight After Dark
01:18 - Ben Nowack from BenNBuilds Youtube channel & the baloon test
02:55 - Sun synchronous polar orbit reflecting mirror satellites
03:54 - A look at the website claims, a 5km sunlight spot for 4 minutes
05:58 - This isn't new, the Russians did it with the Znamya 2, albeit unintentionally
06:56 - Who's behind Reflect Orbital?
08:12 - What is the Duck Curve?
09:31 - CLAIM: A 10m x 10m satellite mylar reflector into a 12U Cubesat
10:09 - CLAIM: 10's to 100's if BILLIONS of dollar per year revenue!
10:35 - CLAIM: $50/MWh energy sale price after dark
11:18 - CLAIM: $175k/year revenue from each satellite & launch costs
11:58 - CLAIM: 200W/sqm? Err, in what universe?
12:24 - DaveCAD calculations
13:10 - 100kW maximum capture is reduced by the tilt angle
14:05 - 5mW/sqm. FIVE MILLIWATTS! Is this a JOKE?
14:50 - But WAIT, what if you combine and focus all the satellites?
16:02 - It gets WORSE! Capacity Factor is a problem.
18:14 - 20MWh/year WOW!, that's a lot, right? Right?
19:22 - Even 20MWh/year become ZERO if it consumes more than it produces!
20:09 - How did nobody do a back-of-the-envelope calculation?

Xena E:
How does this compare with the energy reflected by a full moon.

I'm sorry, but lunatics have to be involved somewhere, all very teslaesque.

Roughly the same energy per sqm received on earth. Single digit milliwatts.

schmitt trigger:
This “breakthrough” has received significant attention on the interwebs.
And the unanimous response has been: WTF?

I wonder how many investors have been fooled already.

Just the one so far according to crunchbase
