These are awesome! Very cool idea.

I think these toys are an ingenious idea for combatting obesity of any age! When will they be in production ?

These are a fabulous idea - and very cute and appealing in appearance too. :)

great idea

The technical issues in getting a dynamo to correctly record velocity/distance for different rim and tire sizes are formidable. At least there will have to be different settings set to the rim size of the bike in question (10", 24", 700c, 27") and to

Really? A cutesy light up toy is currently in first place? I thought this was about products that were supposed to solve a problem, not toys that light up. This contest is turning into a joke.

My 4 year old wants one really bad, make m quick. you know how persistent kids can be!

I really like these products. It is rare to see such healthy and environment freindly work which is the need of our time.

Sara, these are fascinating ideas, and I think all the kids will love them. I am only concerned with how hard they are to assemble. It is an awesome idea and I think they will really go over big time!!! I am not an assembler of toys, but I do buy

Excellent! Great combo of science and design.

What does making kids more active have to do with greener gadgets? I find the link to this competition for this product to be very weak when compared with the other entries, as cool as they are.

What a great idea to inspire young people to use energy and imagination!

What an innovative product. My kids would love this interactive toy... and I love that it encourages them to exercise. With so many toys ending up in the landfill, being able to recycle them afterwards is important. Young children learn best throug

As soon as these Fastronauts are available to purchase, I am going to buy a few for my five year old son. I think the concept is an ingenious one! A toy that addresses Gross and Fine Motor Skills is a crucial part of brain development. The green aspect as an integral part of toy design will be a guaranteed "Trend Setter". This product with its form, color and function is a winner with my son. He carries the pictures of it around with him in anticipation. Keep up the good work!!!

Nice 2 birds w/1 stone idea, and they're cute, too!

I'm not sure how this reduces our energy use, or is in anyway green. Complicated injection molded plastic toys with generators and lighting?

these may be the coolest things I've ever seen...

I think it's a great idea. The child gets the idea that his own energy can power something and also understands how to recharge it. Green starts at home, and I think this kid's toy is pretty inspiring.

These are great idea. Can they be or are they made from recycled plastic? Really like the mixing of play and exercise (as they don't seem like exercise toys until you look closer at all their functions.) Can't wait to see them in the store.

nice example for what we call "greenwashing"'. all you have here is just another piece of plastic trash- expensive to manufacture and difficult to dispose. the educational part is totally irrelevant. i love the design and the overall idea- but this is definitely the wrong competition for your contribution. forget the green aspect, place a battery inside and sell it to mattel.

I like how these manage to integrate a good deal of tech into a whimsical design. Wish I'd had one when I was younger.

One of our great problems in the USA is obesity in adults and children; Fastronauts would certainly be a unique and fun way to help children lose weight--maybe an adult version should also be produced!

Looks like a great idea. For some reason I see myself having to by four these in near future.

Great Idea Sarah!

Absolutely fabulous! Love the design and colors. What about models for older kids? - MS

Great idea for a useful toy! If the battery assembly is re-used in similar products, it'll knock out the biggest pollutant in most toys. Might get the kids of the gamer generation active, too!

I love it! You can't underestimate the power positive feedback has on kids. And these designs look like toys that my kids would want to play with. In fact, they look alot cooler than anything in our toybox.

Very clever concept and well-designed. I think it's a stretch to call it a 'green gadget' due to the large amount of energy needed to manufacture all the parts. However, any efforts to encourage human-powered transport in kids is probably a good idea.

So cool that we have been making a line similar, kid-powered toys with interactive characters since 2007... the Discover Rig (with lights and sounds) is nominated for 3 'Toy of the Year' awards for 2008... and we use a proprietary wood-plastic-composite (Sprigwood) for our injection molded parts... and made in Canada! Sprig Toys.

I want one, that looks like so much fun.

Sara...Fabulous idea for kids, and cute, too! Get them on the market and we'll buy plenty for our grandchildren!

This wouldn't be all that fantastic for kids that live in places where they con't ride their bike for half the year!

Concerns in environments where we have two to six months of snow... how would we charge these when we really need kids to exercise, and they want toys to play with? Exercycles indoors? Also, I agree that they are just another plastic/powered consumable toy. There are already toys out there that use children's energy to power them.

Health life habits are a must. Anything that will encourage kids to walk and bike instead of driving a few blocks is awesome. I am trying to learn this as an adult and it is not as easy as I had hoped. Keep up the good work!

@David Kenney - yes, they could definitely be made from recycled plastic. They are designed not to need painting (all color changes happen at the part breaks) or roto-molded vinyl parts (both of which are generally toxic processes.) The star and mouth padprints could be removed and just made as texture in the mold. Also, Fastronauts were designed to use a lot fewer screws than the average toy, (and an engineer could probably make the shells snapfit, eliminating screws altogether). All of

What a Great Idea!

Looks great! Good luck!

I think this is fantastic! I like that the at least parts of the toy can be recycled too. The name is cute.

Sara -- This is a great idea and a superb execution. Everyone wants to know how they are doing and feedback is the breakfast of champions! Good Luck.

Very nice. Just so you know Drew got it wrong. The speed of the tire is the same as the ground ground speed so one size fits all just as you envisioned.

The aesthetics are great, i applaud your efforts. The whole foundation of the idea, unfortunately, isn't that impressive. In the end, you have a toy that lights up, big deal. Have you tested a prototype to see if a 5 year old really cares? Doesn't your school teach things like 'innovation'?

@Guy - I spent over a year studying 5-year-olds, their toys, their family dynamics, their classroom and playground behaviors, and interviewed their teachers, parents, child psychologists, and experts in the toy industry before creating this design. So I can say with a great deal of certainty that 5-year-olds would care.

I love this idea. I like how you actually make this 2 toys in one. You can place the fastronaut in the car when the child can't go outside. Or, you can place the fastronaut in the rocket on the bike during the spring and summer. I hope to see this on the market soon.

I love these! I agree with post #20--how about an adult version too? What fun! I want some of these for me!

Cool colors and designs, especially the cycloptic approach. But where will they be made? This could create jobs here and save carbon from it being made in China.
