solar sucks so much bros. Energy return on energy invested for solar is only 4. Which means that a solar panel in it's few decades of operation will only produce 4 times more energy that it took to make it.

>>15330509
I mean it could even be 1.00001 and still might make sense depending on what kind of energy generation method you have
the EROI just basically limits your maximum build/growth rate if you can only use the built energy sources to build more energy
but we are nowhere near and probably will never be close to situations where almost all energy produced is used to build more energy production

well hypothetically if a country was to derive all it's energy from solar it would have to spend a quarter of it's energy building more solar cells. And this also means that there would be a big solar industry, with lost of people committing their "economic output" to building solar, instead of something else

I would need a high quality copy of the original image

Some are saying that SpaceX is sending out false info via journalists to throw off earthers i.e. April 17th only from journos with shadowy sources. This is so that they cant organize correctly to try and halt a launch, and told FAA to not give out a license until they are absolutely ready. Supporting this, NOTMARs are still out for April 10th-12th directly stating launch activities

>>15330353

>>15330738
Kek yeah I’ve heard they plan on launching like, within a day of licensing. And they don’t want to give a public date because they want to throw off the scent for any lawsuits.
It’s just a theory though as far as I can tell

>>15330716
>hydrogen is proposed for seasonal storage
Methane is better

>>15330738
would make sense
after one launch the effects of launching will be known as well, probably easier to make the environmental assessment more accurate (not sure how large of a margins there are in the current 5 launches a year version)
for instance if it can be shown that the decibel levels are much lower than expected and thus damage from that specific are is less, it should be easier to extend the number of launches
I remember that greenhound / oil shill fag whining a lot about the decibel levels, mostly it seemed like it was based on some very shoddy math

>>15330746
not sure if methane was examined in the specific paper but I would imagine the round trip efficiency of methane would be even worse than for "green" hydrogen that comes from electrolytic water
methane is probably much simpler and cheaper to store, but if you look at whole system cost with the added complexity and energy needs to synthesize it?
the white paper expect synthetic fuels will be used for aviation purposes (only like 20% of aviation will be electric) but in that use case the extra complexity on the synthetization step makes sense for easier storage in the actual plane, at least intuitively

I don't have actually have an interesting picture of Starship to use for this meme

> There is an interesting approach that could make this a dual-use system that offers safety features. The bacteria can be grown in a bioreactor, and the enzymes needed to metabolize perchlorates extracted. It has been proposed that rather than fully metabolizing the salt to chloride, enzymes could be applied that will stop at the release of free oxygen (O2). This can be used as life support or oxidant for rocket fuel, or even combustion engines on ground vehicles. The enzymes could be manufactured by gene-engineered single-cell organisms in a bioreactor, or the organisms can be applied directly to the regolith to release the O2 [10]

instead of 0 being some random mixture of salt water (or the coldest temperature in some random city the dude that made the system happened to live in) and the body temperature of people (which is pretty arbitrary too as its not a constant thing)

>Nasruddin replied, “It’s easier than you think when you don’t want to lend it.”

>Orbital attempt
It's a suborbital attempt. You'll be able to tell...because it doesn't do an orbit.

>>15331347
Whats the difference between that, and a site like Space News?

>>15331341
up to a point. With aluminum there's no limit. Also SS is the best space material

>>15331388
What is an orbit?

>>15331388
https://en.wikipedia.org/wiki/Fractional_Orbital_Bombardment_System
We already have the vocabulary. It's a fractional orbital attempt.

Sirs

>>15331388
also it doesn't reach orbital velocity

>>15331396
is it though?
they could probably reach orbit, but lets say I build a prototype car and drive it to the store across the town, would it be correct to call this trip a cross country attempt?
I don't really think so, the capability doesn't matter, what matters is what actually happens
sure driving to the store might in this case demonstrate that reaching orbit is just about keeping the starship engines firing a bit longer, but its not really an orbital attempt
they aren't attempting to reach orbit

The Wet Dress Rehearsal still scares me

>>15331401
orbital speed, passively doing at least one orbit around the earth
I guess it might be possible to circularize at 50km? Its not a stable orbit but is any orbit really, the decay times just get longer up to something like 1000km

why are they doing a second WDR?

>>15331407
I agree.
To be specific, in this case you would have a lot more evidence for calling it “cross country capable” though. For a rocket you could have all the parts fabricated, and you could have test fired your engines on the stand for 8 minutes+ to simulate a launch. You haven’t gone to orbit. Doing something like a hop is even better. Doing something like an intercontinental flight and splash down is better, still

>>15331410
didn't they do one before full static fire of the booster?

>>15331413
they are getting very risk averse
getting this first full stack test right is probably important for HLS milestones and generally getting licenses easier in the future, perhaps political goodwill/leverage

>>15331413
SLS had two also. Different reason though.

>>15331413
they are getting dangerously behind schedule. If they fuck this up NASA might just switch to a different HLS provider

>>15331388
The term is fractional orbit, the difderence between a fractional orbit and sub-orbital is a sub-orbital flight could not have obtained orbit while a fractional orbit would have without having been deorbited early.

All the replies you got are wrong. They want to make sure things will go smoothly on launch day. A starship failure on the pad would set the programme back a year or more.

>The Dugglebys are proposing a radically different flight profile. They intend for their aircraft to take off and then perform a 10-minute boost with its rocket engine. This will send the aircraft to an altitude of approximately 50 km, or half the way to space. Oh, and they're aiming for an airport-like operational cadence of four flights a day.
>To that end, the company recently decided on a fuel mix for its engine: room-temperature hydrogen peroxide and Jet-A, the fuel used by a majority of jet aircraft already flying at airports. The company's engineers also recently achieved liquid peroxide and Jet A detonation, which is important for using a stable fuel composition....One key to making all of this work is using a new type of engine based on "rotating detonation."

>>15330695
Incorrect. Arbitrage and load balancing is only part of total battery capacity, it's very common to see new solar projects get paired with longer duration storage so they can sell power throughout the evening and overnight period when prices are better. As solar capacity increases and there is a flood of excess power during the day, such energy storage will become ubiquitous and kill many of the load following plants that are currently agile enough to work with renewables. Baseload generation is already a dead end.

>Seattle, Washington-based aviation technology company Electric Sky has announced a significant breakthrough involving its Whisper Beam power beaming technology.
>Funded by the U.S. military’s Defense Advanced Research Projects Agency (DARPA), Whisper Beam is designed to send power wirelessly to vehicles while in flight using only radio waves. Once commercially available, Whisper Beam will be perfectly poised to herald a dramatic shift in how passenger aircraft, flying taxis, drones, and satellites carry and consume the energy that keeps them aloft.
>Although the concept sounds right out of science fiction, Millman notes that the idea of power beaming is built upon well-established principles of physics. In fact, he says it was his partner Jeff Greason who, in 2017, noted the solid scientific foundation that radio wave power beaming was built upon regardless of its out-there reputation.
>“When we take our array designs and transfer them into computer simulations, we can easily transfer power to vehicles flying at 70, 80, 90 thousand feet,” said Millman.
>As far as the distant future and where power beaming could ultimately go, Millman says they have modeled a system that can send power as high as 740 kilometers. This extreme altitude is well into low earth orbit, meaning their technology could not only power aircraft of the future but could also power spacecraft or space stations that operate in low earth orbit... the ISS, Millman notes, would be an ideal long-term candidate since it currently employs massive solar arrays to generate around 100 kW of useable power. “That’s a lot of solar arrays for very little power,” Millman says with a chuckle.

Most of the good hydro locations have already been tapped or are obstructed by increasing environmental concerns. The mistake you and/or the EROIfag make is concerning yourself with everything besides economics, where solar and lithium-ion energy storage is already dominating and the mass production of them is snowballing into further cost reduction. Renewable overcapacity will negate the need for seasonal energy storage for much of the world, the remainder will likely use e-methane generated from solar. The most unlikely scenario is one where any of the meme energy storage methods becomes predominate.
