First of all, are you sure the wind is strong enough for the fan to spin? Then there is no problem with a larger inverter, but there is no problem with a larger inverter. Then what is your load? It's definitely not a battery. The power of the battery has nothing to do with the operation of the fan. Try connecting it with a large load. Also, if it still doesn't turn, it means the brake is locked inside, so read the manual. Check if there is any internal structure or anything like that. This problem also occurs if there are brakes and protection. A 1000W fan is generally a system with a simple structure. As long as there is no problem with the inverter, it should be fine. Be careful not to short circuit.
The wind-powered car uses the torsional rotation of the propeller blades to convert it into forward air thrust to push the car forward.
So you can add a small fan behind the toy car, but make sure the fan faces backwards, otherwise the car will go backwards.
Let’s take a look at wind powered cars. It means that the car can drive automatically according to the direction of the wind, and the driver can also manually adjust the "sail" at the rear of the car through a special configuration in the cockpit, thereby changing the driving direction of the vehicle. Mainly using lithium batteries as energy source. It is worth mentioning that it is mainly driven by wind and kites along the way. Wind-powered cars are mainly driven by wind and kites. This racing-style convertible has a carbon fiber body and bicycle tires. Even with the battery installed, the total weight is only about 204 kilograms. Without the battery, the body only weighs 82 kilograms, which is far lighter than Ordinary cars, and the speed can reach more than 88 kilometers per hour.
How it works: Its main power comes from lithium batteries, which are charged at night using a portable wind generator, but sometimes a kite similar to a towing parachute is used. Although this new car cannot yet be put into practical use immediately, it has broad prospects and I hope it will develop rapidly in the next 10 years.
Due to intermittent winds, such vehicles sometimes have to recharge their lithium batteries at campgrounds or laundromats. According to statistics, during the total journey of about 5,000 kilometers, they traveled 2,414 kilometers relying on wind power, 482 kilometers relying on kite pulling, and 2,092 kilometers relying on battery power.
This unusual wind-powered car can reach 2.86 times the wind speed in the downwind test. This rather puzzling car design caused a sensation in Internet forums and universities.
