Spinning a Lego Wheel FASTER

Numinar says...

My first technic lego set was a bunch of gears and a motor with one of the models being a multi-speed gearbox. Had no idea what it was until my dad explained it.

Not that it paid off later but building it and adapting it into other awesome models was the most interesting thing I got out of my first 6 years of education other than basic literacy.

Lucas di Grassi on how quickly Formula E has evolved

newtboy says...

You would like formula off-road, Icelandic off road racing. Those cars have no electronics, just 800 HP motors, industrial gearboxes, and military axles tied together with steel tubing. The things they can do with that minimalism are astonishing.

This is all fine, why not. IMHO Formula 1 is basically approaching this from the other shore most of the time.

Racing cars used to be about adrenalin, taming a beast, surviving unlikely odds and so on, an adventure for gentlemen.

In the last 40 years it has become a competition in pushing buttons, mostly.

If racing cars can have ABS, automatic gearboxes, power steering and all, why not an electric motor?

I still think it is sad and I am glad I saw F1 in the 70s.

BlackFly - Flying Car

jmd says...

If there is one thing I have learned from cinematography, NEVER believe the lighting condition! it is insane how many night scenes are shot in the day and color corrected to night in the final.

I think the cgi-ness is our brains trying to associate what we see with what we have seen in the past. This vehical seems to be;

a) Super light weight hollow body
b) DC motor driven
c) all electric

It is literally a big boy version of modern RC helicopters which also exhibit weird looking physics because the motor totally overpowers the mass of the body.

Obviously most of the footage is of the only way this vehicle can hover, on its back. Being all electric and light, the flight time is likely only minutes.

We have seen many vehicles like this, the only puzzle piece no one is solving is a sustained source of power.

artician said:

Not just you. Also looks like a prototype being lifted by a crane in some shots. The propellers look too small to lift that mass.
I was also suspicious that they had so much footage under various lighting conditions. The twilight shots especially, which are dangerous conditions to fly under. Could be we're wrong, and just be artful CG for the sake of a fundraising video?

Shwing!
That's some hard core *quality *motorsports porn. Gt40's always get my motor running hot. Hubba hubba.

Hubless Wheels + Aircraft Motor = Awesome

Ugh... whoever did the editing for that needs to learn how to preview their work before uploading. Music audio one moment, motor audio the next. Rinse & repeat. Annoying as hell.

Porsche shatters Nurburgring record

oritteropo says...

As far as I know you are pretty much spot on. The 919 was run in the LMP1 class with 8 megajoules of hybrid power and a turbo 4 cylinder petrol engine.

This evolution of the 919 has increased the power of both systems, by removing the fuel flow restrictions and increasing the output of the electric motors. The boost graphic is probably showing the deployment of the stored power from the lithium batteries, but it wasn't 100% clear to me (usually they will indicate when it is charging or discharging, and this didn't).

I didn't find a really good reference, but there is a bit on wikipedia https://en.wikipedia.org/wiki/Porsche_919_Hybrid

eric3579 said:

So my limited understanding is that it's a hybrid car (twin turbo 4 cyl and electric motor), and in braking, electrical energy is generated to use as boost coming out of the corner. It helps with power as there may be some turbo lag from the 4 cyl. I however could be completely wrong. Maybe @oritteropo knows for sure.

Can anyone explain the Boost bar there to me? That didn't look like turbo boost, as it was almost never up, but seemed to fire coming out of a corner.

Golf Hazard

Man dives into a vat of oil

drradon says...

Big time stupid move - be lucky if he doesn't suffer some permanent damage. If that is used motor oil, exposure to heavy metals and gasoline residual products is not going to do his liver much good at all... some of that comes right through the skin.

Airfish 8

newtboy says...

To be fair, what I thought is new is the cheaper motor running on regular unleaded gas more efficiently. Airplane fuel is insanely expensive compared to gas, and harder to get in remote places.
Ground effects plane/boats have been around for quite some time, but not in a commercially useful configuration. This seems like a big step up from small ferries or tour boats (faster and smoother rides) and far cheaper than small planes to buy and operate.

Yeah, the biggest ecranoplan was enormous, with immense lifting capacity but little evasive capacity, so they were awful in practice as military vehicles except as transports well behind the front. I can't find any instances of them being used in conflicts.

Ashenkase said:

Yep,

What once was old is new again! This tech has been around for decades.

Here is a Lun-class Ekranoplan on the Caspian Sea.

I can only guess those are nuke rated missiles it is firing.

8 nacels, the things HP must have been huge.
