What kind of R/C truck would you recommend for a 10 year old?

electric cars for kids 10 mph image

rulekeeper

I'm 14 and I have a T-MAX 2.5. I want something for my brother that is pretty fast but isn't 40+mph. I don't want to get him a T-MAX or Revo because he'll just blow it up, jump it off a cliff, or make it fall into the creek. Would the electric Stampede be alright? What would you suggest?

Answer
Car Guy is right, for a 10 year old don't spend a fortune on one until he gets older. The high tech ones need too much maintenance for a kid.

How does Tesla Automotive help the environment ?

HeartThrob

I keep hearing that Tesla is making the environment a better place because it's taking cars with IC engines off the road.

Well energy cannot be created -- it can be transferred...... so the energy has to come from somewhere right ?

Okay, so people plug in the cars to derive their fuel source from a socket in their house. The power source can be traced back to a power plant burning coal or fossil fuel ( IC engine based powerplant which uses LNG).

If energy is energy, doesn't the same quantum of energy taken for all those cars that would have been on road come from a fossil fuel burning power plant instead of a gas pump ?

Imagine me kicking a 10 ton ball. Let's say I have EAT a ton of food to have the strength to do so. And it takes 100 units of energy to do so.

Now that 100 units is needed to kick that ball 5 feet regardless of whatever is being used. So instead of me kicking it, imagine a robot kicking. This robot still needs 100 units of energy. And it will get it from where ? it will poof out of thin air ? No...it'll get it from the coal that's being burned in a power plant which is producing energy that's transmitted to the robot wia copper wires over a grid.

So what's with the hype around Tesla ?
READ EDIT:

I don't want answers that beat around the bush about how great tesla is, so forth and so on... yada yada yada...look at the answer of the first replying individual, his username is "In Science We Trust" .

I DONT CARE about how much boot space a tesla has. All I want to know is, how does putting a Tesla on a road use any less fossil fuel than a ICE based car. With a tesla you're using power from coal based power plants. With an ICE car youre using refined crude oil from under the ground.

Answer
You question is almost as stupid as your username and photo. The energy efficiency for any moving vehicle, whether powered by an electric motor, an internal combustion engine (ICE) or a hybrid design, comes down to overcoming energy losses sustained during operation. The losses can be classified into two categories: road-load and energy conversion. The design engineers at Tesla Motors have incorporated groundbreaking innovations in overcoming both types of loss. If youâre driving one of the new Tesla S Models you immediately become aware of this as your car quietly rockets from 0-60 mph in just over four seconds, covering a quarter-mile in about 12 seconds (reaching 108 mph).

This is definitely sports car performance but contained within a beautifully-designed luxury sedan. The carâs sleek look is a major contributing factor to overcoming road-load loss a perfect marriage of form and function. Overcoming Road-Load Losses

Road-load loss includes the forces that cause a vehicle to expend energy for purposes other than propelling it forward, such as:
â¢Wind-resistance (drag)
â¢Gravity (vehicle weight)
â¢Rolling tire resistance
â¢Mechanical friction caused by bearings, brakes, drive shaft and hubs

To overcome these road-load loss obstacles, primarily in an effort to extend the driving range of the Tesla EVs, design engineers went to work to build extremely aerodynamic, lightweight bodies that are shapely, slippery, and really look good too. High-performance, low rolling resistance tires are used and all moving parts are made of materials and constructed to be as frictionless as possible. Energy Conversion Losses

Energy conversion is the process of delivering power from an energy source to the drive wheels that ultimately propel the vehicle. Lithium-ion battery cells are used in Tesla EVs because of their superior energy density. Although some energy is lost to heat in the battery pack, the extreme efficiency of the Tesla EVâs powertrain (the motor and the drive inverter) allow for near 90-percent efficiency.

Compare this to your typical gasoline-powered car with an efficiency of about 35-percent and the difference is astounding. Even hybrids donât come close to this level of drive-efficiency, since they are also dependent on a gas-powered engine. Nearly two-thirds of the power produced by an ICE is lost as excess heat created during the combustion process.

As for the reason for the hype... when it comes to what matters - how it looks, drives, features and functionality it is a screaming HOME RUN. What has it got? Looks... Incredible performance (0 to 60 in less than 5 sec)...great handling (due to extremely low center of gravity),... a beautiful and well designed computer interface.. an amazing amount of cargo space. No kidding, it's over 55 cubic feet! When you think about how Tesla has replaced a huge, inefficient, polluting, noisy engine with hundreds of moving parts that can wear out with a motor smaller than a beer keg and battery pack on the bottom, isn't it a huge Duh, this is way better?! The Model S is absolutely the coolest car on the planet.

Additional info
According to the Union of Concerned Scientists... "Nearly half of Americans live in regions where driving an electric vehicle means lower global warming emissions than driving even the best hybrid gasoline vehicle available. Over the lifetime of an EV, the owner can save more than 6,000 gallons of gasolineâa significant contribution to U.S. energy security. But our nationâs reliance on coal-powered electricity limits electric vehicles from delivering their full potential. Only by making improvements to our electricity gridâby decreasing the use of coal and increasing the use of clean and renewable sources of electricityâwill electric vehicles deliver their greatest global warming and air pollution benefits."

"To meet the challenge of climate change and reduce our nationâs dependence on oil, continuing to run our cars and trucks predominantly on oil-based fuels is not an option. On the other hand, electric vehiclesâcoupled with clean and sustainable electricityâare important parts of the solution."
