We are building the world's highest temperature heat pump. It can reach 1000℉, when other commercial heat pumps usually reach a maximum of 320 ℉. It is a big deal because factories have to rely on polluting natural gas to produce their process heat. We estimate that it represents 3% of the world’s annual CO2 emissions and a $10B+ annual market opportunity. We are currently building a 5kW prototype at 480℉/250C to coo…

This is really cool. Can you talk about some interesting challenges/problems you encountered?

Our company is developing affordable phased array antennas. The end goal is to serve the next-generation commercial wireless communications and sensing markets (e.g. 5G/6G, mmW imaging radar, etc), though as we're bootstrapped most of our work currently is in Defense. On the very off chance there's other RF or antenna engineers out there, we're hiring (US remote)!

What's the name of the company?

I am making and selling an eink smart screen. It can display a google calendar. You can also point it to any url that serves an image. Is it okay to post a link? https://shop.invisible-computers.com/products/invisible-cale... I am planning to release more applications for it and I am opening the platform for 3rd party applications.

Oh, a fellow hacker from my little home town :-) Greetings from the other side of the fjord and best of luck with your business!

We make the world's best baby car seats. https://www.kioma.us Fatherly Magazine calls it "The Car Seat of the Future". It's been crash tested, flight inversion tested, flammability tested and mom tested. It is full of patented innovations to make kids safer and parenting more enjoyable. It required lots of material science, production techniques, supply chain adjustments, and a surprising amount of software (to model…

We also have a baby seat that can pretty much say all the same things. There must be tons of these on the market with swivel etc. What makes this better than the rest?

1. Safety (* see below)

2. Ease of Installation (* see below)

3. Bauhaus Design

4. 1-Hand Operation

5. Ease of Cleaning

6. Built in Rocker (a full one)

7. Quiet (* see below)

* Safety > The US regs are pass/fail so lots of seats on the market have mediocre test scores that don't reflect the real danger of severe concussions. For those of you interested in digging into the obscure world of Head Injury Criterion: greater than 390 HIC is linked with severe concussions (Source: Proposed limits for HIC From Kleinberger et al., 1998, and Eppinger et al., 2000.) Kioma seats do a number of things (crumple zones, etc) to create a lower (better) HIC score. By comparison some of the top sellers in the industry are at 600+ HIC.

* Installation > The regs don't have standards that really address this, but the incredible complexity of legacy car seats has led to a lot of installation errors by parents and caregivers. This can lead to some really unpleasant outcomes and injuries. We designed KIOMA to minimize use and installation errors by making things as simple and intuitive as possible. This seat is optimized for lap belt use only (no base required). The companion base has a number of innovations too that make it intuitive and easier to use.

* Quiet > There are no clicking or snapping or button parts that wake a sleeping child (with the exception of the harness buckle). This is the quietest baby car seat made.

Earlier quoted context omitted.

The strap is a single point of failure. Each mount should be attached to the seat brackets individually. Those brackets need to be braced and not just bolted through plywood. Having patents on innovations is necessary, but if you have innovations that will save kids lives, you should find a way to make those broadly usable by all. https://patents.google.com/patent/US10967762B2/en?oq=1096776... This this TOS usual for…

I wonder if there would be a market for in-built hard modular mount points for the back seats. Like, let's say I'm Tesla. I build in mount points for the back seats. And then I sell accessories for the mounts. Tesla branded baby seats. Child seats. Storage/shelf solutions. Dog cages. Pizza delivery rack. Who even knows how many things one could put back there

Like isofix? I think even Teslas have that. Or do I misunderstand?

These look amazing, like they solve all the pain points I've had with car seats over the past five years. I'm a little past that stage now but wish these had been around when I had little babies.

Thanks!

Will you sell in Europe and does tha car base have an isofix mounting?

We're building Volition [1] to organize the world's mechanical components for MechEs, roboticists, mfg. techs, and beyond. Imagine McMaster-like UI quality, but ultimately across every good OEM / distributor. I previously built Plethora (automated CNC machining) and am happy to help all hardware / manufacturing startup folks. Please feel free to reach out. [1] https://govolition.com/

Ever since I first touched Octopart, I've wished there was an Octopart for mechanical components. This looks like it comes very close, and I love the look and feel.

Sizing > Realistically, the seat fits average kids up to 3 years. At the 95% percentile on height most kids will outgrow a rear-facing car seat at 18 months (the growth of the torso is the limiting factor). From a labeling perspective we have to be careful, though, because the US regs on sizing are really terrible. Keep in mind the regs were written in the 1970s when we were still teaching Americans to wear seat belt…

> The Kioma seat is like a Maserati Perhaps not the best brand to invoke for a product where reliability is paramount. If you want to convey both luxury and reliability I'd go with Lexus (fancy Toyota).

;) Point taken.

We're building FPV humanoid robots to do hands-on jobs from home that can be controlled with standard VR headsets: https://robosymbiosis.com/.

Still very much a work in progress. I'm a little obsessed about the UX of things, so I'm really trying to drive the idea that it should feel as natural to use as moving your own body. I love that it combines tons of aspects from VR game design, robotics, and web technologies into a single experience. I expect to have a full scale, really rough looking but functional prototype by this fall.
