"The interchangeable battery is also a nice feature.  It helps to prevent the vacuum from being discarded when the battery dies and can be separated to be recycled."

" It can be a bit difficult to judge the scale from the photo, but it looks like this could also be a suitable seat for people who need a rest while walking up the hill."

"Mix wet concrete with burlap and set it over a shape.  You can reinforce the structure with more layers if required.   "

"  The redesigned barriers are missing out on two important features of the current models.  The base of the barriers protrudes at an angle to help change the direction of the momentum of cars hitting the barrier.  The second is that the tapered design also allows the barriers to nest when stacked so they can be easily stored and transported.Going back to an article from May (https://www.core77.com/posts/88545/A-Triumph-of-Design%E2%80%94and-Manufacturing-The-Story-of-Cubipods-and-the-Innovative-Mold-Required-to-Make-Them?utm_source=core77&utm_medium=from_title, there is a benefit to simplicity in mold design."

"Paint doesn't have the strength required to hold sand for very long, especially if you're shoveling.  For non-slip applications on exterior surfaces, you should use an aliphatic urethane coating that will stand up to cleaning abuse and retain the grit.  Epoxies generally aren't advised for exterior applications.You can also add a reglet with a carborundum strip for additional traction.  This creates a little bump that your footwear treads will catch on.  This is what we'll install on polished concrete floors which can be slippery when wet.  The bump also provides feedback to users who are visually impaired that they're about to reach a change in elevation.1"

" The first seating solution was featured on Core77 as a reader project: https://www.core77.com/projects/77806/Opposites-Attract-with-the-Delirium-Chair"

"This isn't a test for delivering pizza, this is a test for delivering ingredients.  Eventually, food will be cooked and maybe even prepared as it's driven to the destination, reducing the need to keep pizzas warm.  If you're just driving ingredients, you can locate your supply depots in much more affordable locations off of the beaten path since it doesn't matter if it takes 10 minutes or 10 hours for the vehicle to reach you at home.  Pizzas are perfect because they are small and they're easy to prepare and cook.  While a car likely wouldn't have enough room for the production of a pizza, a UPS style delivery truck might. "

"There's a sister competition in Canada called the Great Northern Concrete Toboggan Race with similar objectives and processes but geared more towards the Canadian climate. "

"There's many Canadian readers!  Many!1"
