Comment Copper wiring. (Score 5, Insightful) 597

Low voltage is not going to happen, if only because the costs for copper wire would be astronomical. If you take your standard 1500w electrical outlet, at 120v it only needs #14 gauge wire to run 54 feet @1800watts because it's only 15 amps. If you take that down to 24V, you need #2 gauge wire to run the same distance, and you are only getting 1200watts, at 50 amps! #14 wire is about $0.17 per foot, where as #2 wire is (from what I could find) about $7.50 per foot.

Comment Re:Why have 2 wheels when you can have one? (Score 1) 134

The specific one I have came from a factory called CXM. But I think this market is changing really fast. A similar one to mine is this one here: It has twice the battery capacity of mine which would be helpful. Mine has taken a serious beating and is still working good aside from the plastic shell which has a few cracks. Just cosmetic though. I let anyone try it so it gets crashed a lot.

There are other ones that have bluetooth connectivity to your smartphone so you can see capacity and stuff. The genuine solowheel ones are really nice but are so expensive and I've never tried one.

Comment Why have 2 wheels when you can have one? (Score 3, Informative) 134

Been having fun with a solowheel clone you can get on bangood and aliexpress for about $400 that is just one wheel. Have taken it camping and ran it on gravel, packed dirt, grass etc and it does a pretty good job. Super fun at campsites particularly. Even last summer in BC I used it to haul stuff to and from the car to the beach. It's infinitely more useful than a Segway since it only weighs like 21 pounds. I used to ride it through downtown on my way to work but haven't felt like it lately since it attracts so much attention, where people stop you to ask all the questions like how fast does it go (12km/h), how far does it go (10km), how much did it cost etc.

Here's a video of when I first started learning it. I'm much more comfortable on it now, I can even pull my 2 kids in a wagon while riding it.

I never really understand the comments, particularly on a tech site like this, such as 'why don't you just walk you lazy'... For one thing walking isn't that great of exercise anyway if you are in any kind of shape (ie. not round). Secondly, this thing is twice as fast as walking and effectively doubles your range of parking options etc, and it's actually fun.

Comment Re:Specialized Pieces (Score 1) 355

Not entirely true, if you're creative enough. For example recently I bought my 5 year old a Mixel. It had these hook like things on it for horns that, as you suggest, I thought were specifically for that model. However to my surprise he remembered that the same pieces also came in a spider-man lego kit, ran up stairs and managed to find it within a minute (which is a feat in itself considering how much lego there is). So even the kits themselves are still a good creative toy, even when they eventually get mixed in with all the other lego.

My favorite is the MSDS for sand. Like at the park. Imagine this warning at the playground, haha!

Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.

Personal Protection in Case of a Large Spill: Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

Comment Re:Not all Lithiums the same (Score 1) 236

If a LIPO based car is a bomb on wheels with an energy density of 0.36[2]–0.875 MJ/kg, then what would you call a regular car when Gasoline has an energy density of 100 times that (~46 MJ/kg)?

Although, I guess you'd need to consider the speed at which that energy can be released, and I'm not sure how LIPOs compare on that front given that gasoline needs to be sufficiently mixed with oxygen.
