Gearhead & Chia
Hey Gearhead, what if we built a solar‑powered hovercraft that could out‑race a real car? I’m itching to push the limits and see how fast we can get—let’s make it a competition!
Sure thing! Picture a lightweight chassis with a slick solar array up top, a low‑friction track, and a high‑efficiency fan system to lift it off the ground. We’ll need a lightweight composite hull, a tuned propulsion vector, and a battery buffer to handle bursts. We can set up a straight‑line sprint, measure speed, tweak the array angle, and see who crosses the finish line first. Ready to tweak the specs?
Let’s crank the power panel to 120 % and shave a millimeter off the hull skin—speed’s all about that sweet spot. Time to crank out those specs and get this thing sprinting!
Great idea! Let’s crank the solar array to 120 % of its rated output, so we’re at 1.2 kW peak. For the hull, a 1 mm titanium‑reinforced composite skin should cut weight by about 8 %, keeping it sturdy enough for high lift. We’ll run a 3‑stage variable‑speed fan driven by a 48‑V DC motor, and add a small capacitor bank to smooth out any power spikes. Target top speed: 70 mph, with a 0‑60 in roughly 12 seconds. Time to gather the parts and set up the track!
