#SizableEnergy is a clever name for the startup.
Let's hope that the energy generated by gravity working on a density gradient to turn turbines is "sizable" enough to offset the energy required to pump sizable amounts of brine from a tank on the seabed to a floating tank on the sea surface.
Wouldn't turbines turn more efficiently in deep ocean cross currents?

#ReflectOrbital, a #US company, is pitching giant mirrors in space to reflect sunlight at night.
Let's hope that the benefits from this one too are sizable and the costs insignificant.

A U.S. company is proposing to 'sell sunlight after dark,' saying it could help power solar farms and provide access to light in emergency situations. Astronomers are not only concerned about what this will do to the night sky, but also to wildlife.
⬆️ @sundogplanets >> The costs are high, the environmental effects are potentially catastrophic, there are huge safety issues, and the benefits are negligible.
@nebulousmenace >> *nods* my hope is they're just in it to harvest venture capital.
That was #ReflectOrbital in October 2025. Now, yet another startup #Helio makes the case for #SpaceSolar or #SBSP
This one seeks to harvest #solar energy, convert it to microwaves, and transmit it wirelessly to Earth
