Endlich generiert Deutschland, vor allem jetzt im Sommer, den meisten Strom aus erneuerbaren Quellen (Sonne & Wind), und jetzt will man die saubere Energie nicht nutzen?? Nachdem man Milliarden für die Energiewende investiert hat, und ein gewaltiges wirtschaftliches Risiko eingegangen ist?

bought a portable one 2 years ago. works wonders. even though it isnt as efficient as fixed ones, it still manages to cool down the inside air by ~12C compared to the outside air, even though warm outside air has to come in to replace the evacuated inside air. If you sit in front of the cool stream, it’s even too cold!

My baby girl loves napping next to it during the day.

As for the climate, CO2 sits at ~300g/kWh here in Germany right now, so that’s about 3kg of CO2 if I have the thing running for 10h/day. Furthermore, in these hot sunny days, most of energy production during the day in the country comes from solar (also a lot of wind)

after all the money spent pushing for renewables, the plan is indeed yielding some results, so I’ll make sure the new clean energy gets put to good use, lest the billions were spent for nothing.

I bought an indoor 1kW AC unit 2 summers ago and my baby girl loves napping next to it during these hot summer days. I couldn’t imagine having her withstand so much heat for no reason.

here in Germany the trend during the past months has been 305g of CO2/kWh, and assuming I have the thing running for 10h/day, that’s about 3kg of CO2 I am generating; so you get 3kg/day more of CO2 for your methane production and my daughter gets to sleep well; that’s a win-win!

@esherifftv congrats mum and dad! 🥳🫶🏻

[Blue Origin @blueorigin]

Continuous sunlight is scarce on the Moon unless you know where to look. 🌑

The lunar poles contain "peaks of eternal light," areas bathed in near-continuous sunlight. Power Tower mounts on Blue Moon MK1's top deck and extends solar arrays to 26 meters total height to capture that energy and deliver sustained power for Moon Base operations.

Check out this video of Power Tower during a successful deployment in an analog lunar environment.

The infrastructure era of lunar exploration starts now.

Man, seeing the USA from the world cup tourists makes me realize how much cooler the country is than I thought! (and I already liked it)

I’d really like to visit! 🇺🇸

@BellikOzan Congratulations! Have a wonderful time with your family and especially the new member🙂👶

@esherifftv my baby girl turns 8 months old today!
all the best for you and your baby, your life will indeed change a lot; it’s gonna be challenging at times but incredibly beatiful and rewarding. Life feels just right with a child! ☀️

[Hector J.C. @SpaceBeetle1]

yeah thinking more about it, a heat pump probably isn’t the most efficient/smartest thing here; real compressors normally run at maybe 40%-60% Carnot too anyway; maybe for daytime lunar surface refrigeration?

the ISS pumps single-phase amonia through the radiators sitting near the load temp, and that works well. maybe SpaceX are doing something similar

[Hector J.C. @SpaceBeetle1]

@steph4n @davepl1968 the’ll probably just use a vapor compression system; read about how A/C units or even your fridge at home works

their skill, their ability, their knowledge, their hard work; I have no right to demand access to any of it.

If I want something similar or better, there’s nothing preventing me from starting a similar venture myself other than my (other) interests in life, IQ and belief system.

@ModernCeasar should I read them in the listed order?

[K2 Space Corporation @K2SpaceCo]

It’s official: K2 Space is operating the most powerful Hall thrusters currently flying in space. Just a few weeks after the launch of our first test mission, Gravitas, we’ve successfully fired both of our 20kW Hall thruster systems to achieve a new level of electric propulsion power never before seen on orbit for this type of system. We plan to continue raising and lowering our orbit as we gather more data on the thruster performance while continuing our mission in LEO.

This milestone is yet another validation of K2’s approach to building bigger, as more powerful thrusters will enable the MEO, GEO, and deep space missions of the future.

Some LC-36 updates. Now that we’ve had access to the pad and integration facility we can share a bit of good news. The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good. The big support tower is damaged, but it can be repaired in place rather than torn down and replaced. The booster “Never Tell Me The Odds” and the three GS-2s that were onsite in the integration facility also look good.

I’ve seen some speculation that we might move directly to the 9x4 configuration, but we won’t do that. Rate manufacturing of 7x2 is going well, and we’re going to continue that at pace as planned and store the stages for use. In addition, we had already been working for some time on eliminating our transporter-erector in favor of an alternative vertical conop, and we’ll now go directly to that; so we don’t need a new transporter-erector.

We will fly again before the end of this year. Gradatim Ferociter.
