Hadn't heard of that, but I get the concept. Cool idea.

Off the top of my head, I'm concerned about pump and generator efficiency. You're going to use some amount more energy to pump a volume of water up to the high basin than you will get back by gravity feeding it through generators. To be fair, efficiency is a problem with using and recharging chemical batteries as well, but the limited amount that I remember from college engineering courses tells me that efficiency in the electrical / solid state world tends to be more easily obtained than in the mechanical world.

And as another "to be fair", efficiency is a bigger concern for things like fossil fuels, where burning one unit of fuel produces a set amount of energy and you have to improve efficiency to get the most value out of that energy. With things like solar and wind being "free" energy when active but requiring storage for when the source is inactive (night / calm winds), efficiency still certainly matters, but not as much as with a scarce / non-renewable source of energy.

Anyway, I'd like to see concrete numbers comparing the utility and efficiency (in various metrics) of your hydro storage vs battery storage.

Ok....they start with a few mistaken premises.
Most importantly, the premise that energy is best stored in a chemical battery. It sounds good, but it's simply wrong. The best way to store large amounts of energy is in a hydro/gravity storage system. This is a two basin system, with two basins at different heights with a pump/generator linking them. When you have excess power, you pump water uphill. When you need more power, you let it flow back down. It's ecologically friendly, cheap, and effectively never wears out like batteries all do, it can work on any scale, and unlike most hydro doesn't impact a living river system. It's proven technology that's head and shoulders above battery banks.

"There's no gravity in space"
Eh, it depends who you're talking to. If you're explaining to kids why things float in space, that's a reasonable approximation. If you're teaching physics to high school students, you're really doing it wrong.

"Trojan horse"
When was this ever presented as fact? I actually remember learning about the search for a possible real world site of Troy and I remember being taught the STORY of this, but given it was in the same story about a guy who could only be killed in the heel, we weren't expected to believe it was 100% accurate. Talking snakes on the other hand? Totally real.

The rest are reasonable enough.

You should check out his other songs. Most i'm guessing you will know. They are all amazingly well done. I'm surprised more people don't love his stuff. Here are my faves.

When I rode 30+ miles a day, almost 30 years ago, I used to do something similar on downhills. I wouldn't take the toe clips off, but I would hang my ass over the rear wheel with the seat in my gut. This flattened my body and made me more aerodynamic (but not nearly as much as he is) and put my weight farther back and lower, meaning I could brake much harder without going over the front. His center of gravity probably goes higher in this position with his legs that high. Since my feet never left the pedals, I could still pedal if needed and get back upright in an instant.

I never raced, so I don't know if this would have been against any specific rules, but taking your feet off the pedals that way would make you far less stable, imagine if he had to brake or swerve, and reattaching at speed is no walk in the park either, so it's probably considered a likely hazard to others and banned...but that is just a guess.

That's right, keep taunting gravity like that and eventually gravity will decide it's had enough of your silliness.

The Anti-Gravity Lean got me.

As a far-left Liberal, I 100% agree with Bill on this point. I understand the underlying idea behind PC -- that all people deserve respect and shouldn't be singled out for ridicule for things they can't help -- but the execution of this idea has been a disaster.

Nobody likes it when someone shouts out, "I'm a victim!" when they're obviously not. It demeans real victims, lessens the gravity of the word and concept of "victim", and makes the person calling themselves a victim not so much that term as the term "Cry-baby". Thus it makes all the people in the class (Liberals) generally associated with that group (whiners) look like specials snowflakes pleading for special, and unearned, treatment.

So if identifying new species of victim-hood is going to be your principle reason for existing, then you'd better expect to lose and lose often.

I thought you could easily watch gravity waves by looking at the ocean tides.

Y'know, the first thing the new Tarkin brought to mind was LA Noire. To be honest, I think LA Noire did the whole face-scanning thing much better. Now, they had an easier job to do, where the whole game is already CG so perhaps the faces don't stand out as much, but it does feel like they did a better job.

I actually think they tried to control Tarkin's face a little bit too much. I think there will perhaps be a 'realization' in the industry that adding a host of very subtle random fluctuations to a face will make it seem more real.

I found the discussion about lips sticking together to be fascinating, and that's certainly headed in the right direction. There's probably something about gravity being applied to faces that make them seem realer, too. Like that they subtly jiggle and bounce as they move and that at a miniscule level the skeleton of the skull moves first to push the musculature and skin of the face around second. Those kinds of subtle movements are probably what could make this kind of thing realer.

I was thinking more people would have been floating up from the gravity of the other planet or whatever it was. Need to get Neil deGrasse Tyson on this one.

Very impressive considering differences in centre of gravity and weight distribution.

Monster trucks are awesome!

I get lowering the centre of gravity, but wouldn't that also affect the clearance?
