Awesome. Thank you!

We weren't ready to apply to the carbon xprize when it was announced. But we're ready to scale quickly with Y Combinator!

We grow conductive multi-walled carbon nanotubes. Some of the layers may be semi-conductive. But in bulk they are a conductive material. We haven't refined the process to the point where we can select for conductivity type yet.

The CNTs we are making right now are about 10-20 microns long. Making them longer is a focus area for us. However, the nano-materials department at Rice has created a wet-spinning process the can bundle CNTs into continuous fiber. They aren't quite a strong as a continuous CNT from what i've heard, but still stronger than carbon fiber.

maybe it'll buy us some time to figure out fusion! I think if we can get the electric car market to a more significant level as well (and power them on renewables) that would also have a big impact.

We like the battery idea the best as well. We've chosen that as our first product to market. Me make multi-walled carbon nanotubes which are conductive in bulk. Its possible that there are non-conductive layers, but they are encased by conductive layers that counter act them. For concrete i've sen research showing 50% improvement in strength with 1% carbon nanotube concentration. We haven't confirmed this ourselves yet, but we are starting up a testing program soon. We are also planning on scaling with renewables like hydroelectric. If in the future carbon nanotubes can be used to replace aluminum as a structural material, there may be an opportunity to use they hydroelectric they were once operating on to power the process. But I agree, to reach a massive scale, we will need massive renewable energy. But I think we need that anyway!

Yes they can. Always looking for new applications!

If all goes well at demo day we'll be looking for mechanical engineers! Please send your info!

Thank you! My father is an awesome guy with a unique perspective on the future! I'd rather not get specific, but having an initial angel investor was crucial for us to be able to generate the amount of data we needed to win our first grant an keep things moving forward.

only certain types of carbon nanotubes that have a thick and rigid structure have asbestos-like qualities. These are no longer used outside of Asia. The thinner, flexible variety similar to the ones we make do not share these qualities an do not penetrate cell tissue. Similar to carbon black, which is a widely used nano-material in car tires. Carbon nanotubes are also sold in solution and in dispersion so they cannot easily become air born.

Haha, thank you! Our site definitely needs an update. We have a more detailed website in the works! I'll keep you posted!

This is for sure a tough challenge. I think supercharging stations charge at 400V and 250A for the model S. Porsche and others also have 800V chargers coming online.

that would be awesome. thank you! ill send you an email.

Agreed. That is definitely a problem that needs some attention. There is a big research effort going on at the Department of Energy "Enabling Extreme Fast Charging" that is providing funding for solutions to fast charging from the battery performance end and from the charging infrastructure ends. Hopefully industry finds some solution sooner rather than later.
