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 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…
What is the COP of a heat pump operating against this temperature gradient?
And that's the absolute theoretical maximum, you would be happy to breakeven in practice. Unless you have access to waste turbine exhaust, geothermal water, solar collectors or something along those lines, I don't see any practical application where the marginal energy savings would recover the capital costs of the pump at 1000F.
But hey, they have software modeling and venture financiers, so I'm sure they are not overselling it and it's all excellent and double plus innovative.

Can you tell me the difference between your product on the types of prescription cgm + insulin pump combos like dexcom/tandem which offer some level insulin control? I'm just curious. I run an xDrip set up and I've played around with a couple of the "DIY" closed loop setups.
Hey, my wife has diabetes, and she's had really awful luck with automated blood sugar monitors. Somehow their readings are always off by insane amounts vs a finger poke Have you done much research into that area? Do you know if there's a brand we should check out or any common gotchas? (I can't find much reasonable info on this online due to my poor Google skills and all the bad info out there..)
I own multiple interactive entertainment concepts. We build room scale hardware and props. So definitely a bit different than normal consumer hardware, but still have a lot of the same problems. One of our issues is we our low volume and unique use cases for our hardware. I’d love to connect with anyone else doing similar things. My info is in my bio. Breakoutgames.Com Activate.games
What sort of issues do you have? Is the hardware very custom?
It seems like a concept that could explode as a franchise or even template model like escape rooms a few years back.

This is really cool. Can you talk about some interesting challenges/problems you encountered?
We started in 2016 with just an idea, and we probably encountered every problem you can think of ! - hard to raise funds for large deeptech projects (thank you YC and Wefunder for unlocking that one!) - a corrosion issue in 2019 that nearly killed us (we found a way around it after months of brainstorming and completely got rid of corrosion issues) - we had to build our own physics algorithm for very specific problem…
It got me wondering, would your heat pump be a solution to improve the efficiency of those plants?

I am a parent, and in my opinion, spending $1k on a car seat is completely unreasonable. (We bought ours used as part of a package deal with some other used baby stuff. It would have been nowhere near $1k when new.)
When buying used car seats, remember to check the "use before" date that is marked on it. They only claim to achieve the designed strength/protection for a number of years. At least in Europe.
At my company we're working on building smart boilers, where what's actually heating the water is servers. We then send customers computation to those boilers. This way of doing things allow us to eliminate a lot of carbon emission for computation that would otherwise have been done in classic hardware where the heat is not reused at all.

I am very sceptical of crowd funding however, I think these are largely terrible investments for consumers while explicitly targeting people who are not accredited investors.
what made you go that route instead of pursuing VC funding?
We make tiny Linux servers packed with real devops tools (but also sporting a somewhat-easy-ish-to-use UI) for home-hosting and self-teaching: https://pibox.io - works great with Jellyfin!
