"It will be fun to do but his is hardly a solution to anything, is it? The recycling advantage is dwarfed by the energy waste."

"Now consider this kind of issues and solutions on flying cars..."

"Cars still imitate the same wheel configuration as the horse-drawn carriages. And even electric cars, which have no need to do so and should be freer to be shaped differently, still have that configuration. The reason for this is the road infrastructure that sort of mandates this setup.This signifies to me the problem of making personal flying vehicles. Over the years we have seen several designs, of which this one is one of the prettier, that where never commercially successful. The importance and lack of a well designed infrastructure being the reason, in my opinion. In itself it is a small vehicle but it requires a lot of three dimensional open space to safely operate it. Never have I seen that addressed as part of the design."

"All design is marketing.This guy seems intimidated by these "controversial" designs and in the end comes to a personal conclusion they do what is expected of them. I don't think being polarizing was in either design brief; he and his community were polarized themselves."

"Have you actually read the comments?"

"It's a sweet thought but this should work if the material to drill is limited to foam and occasional cork only. And then it is still has the volume of a full sized drill."

"The first next step should be to make a decent base matching the sphere design. No checker plate."

"It always surprises me: are these people aware they are designing electric cars?To me it looks they design a combustion engine car and glue a plastic grill to it.There should be so much freedom in design here!"

"Isolator Cups? With cooling fins? It might hold nice but your hot beverage will cool extra quick."

"The cyber truck is the first proper design by Tesla. A classic in the making."

"When the request was for "your wickedest and most outrageous designs for a Ram truck" the results are quiet conservative, no?"
