Maybe a really big zip strip? www.fabtintoys.com/kenner-ssp/

How big of a flywheel would a car need to drive 100,000 miles without ever recharging?

Hamburger

That's my favourite type of car. Here's mine

“You’re gonna want to avoid table edges.”

toingggg!

Parts of it traveling on escape velocity trajectories would be spectacular indeed.

Like in cartoons where parts are ejected everywhere

We have high hopes that the added incentives will lead to safer driving.

A car that works solely on clockwork? This has to be a wind-up!

I hear it has trouble with high hills.

As a kid knew another kid who was sure it would go further if you kept pulling back after the clicks so he'd pull back, hold the drive wheels, and pull back again like 10-20 times and then get super excited about "how far it went" even though it didn't actually go any further than it would've

i propose retractable floorboards, to enable easy winding, call it Step 'n' Go

Can we get a "What if...?" of how feasible this would actually be?

Well, with Fiats from the Sixties, this wasn’t far off.

Makes me wonder if anyone has tried charging up an EV with regenerative braking, by manually pushing it forward with a brick on the brake pedal

No put the tesla factory on top of a mountain, then roll the cars down the hill so they end up fully charged at the customer.

Gas pumps would go down as well. As, they are electrically powered.

Oh, it was a joke. Poe's law hits me again.

I give you the flywheel (especially the Oerlikon Gyrobus) and the hydraulic accumulator. www.transportengineer.org.uk/content/feat...

No button on top?

If we had a somewhat common-sized sedan, how much distance could we theoretically achieve via a mechanism with such size?

So much better than my first car that could only go straight while going forward, and to turn you had to go in reverse and it'd go backwards in a circle.

NO REVERSE ONLY FORWARD

Same as with a regular car? The motor doesn't suddenly run backwards if you shift to reverse.

Do not try to repair it yourself

We could do regenerative braking, you just gotta have a clutch on the spring and clearance to flip it.

Not backward, but forward!

"There's a convenient panel under the driver and each passenger's feet so you can slide it open and pull back without getting out of the car..."

so I take it the hamster-wheel engine is a no-go.

Park it in the grandfather garage, lash it to the recharge pulley, and pull the chain to lift the weights off the floor - your car should be done charging in twenty minutes.

A certain white house occupant might think this is a legit way to drive uphill.

No, but in some ways it's safer.

Storing energy is the key. Would be funny to calculate a spring with 50 kwh. And the efficiency.

Sounds super-safe.

This brought back memories and I could hear the clicking sound in my head followed by the sound when I let go.

Pretty sure this is how the Smart Fortwo actually works.

Ah, but that was for planes, or was it for cars also?

The potential energy stored in these cars is explosive.
