Lyon/Delft, April 25th, 2018. iExec and Nerdalize have signed a partnership agreement towards providing sustainable cloud solutions to blockchain applications. Nerdalize therefore officially sells its cloud resources through the the iExec decentralized cloud computing marketplace.

Partnerships Towards Green and Energy-Efficient Computing

iExec continues to gather computing resource providers that will act as the first workers on its blockchain-based decentralized cloud marketplace. iExec’s prior collaboration strategy has been to partner with not only distributed, but also sustainable and green computing providers. Earlier in the year, iExec teamed up two other companies, Stimergy and Cloud&Heat, that share a similar vision of providing energy-efficient computing resources.

It is increasingly becoming common knowledge how colossal the energy consumption needed to support traditional data centers is. The running and cooling of data centers have a combined electricity consumption often greater than that of entire nations, while C02 emissions from powering servers exceeds the whole airline industry.

Nerdalize: Sustainable and Affordable Computations at Scale

The vision of the Netherlands-based startup ‘Nerdalize’ is to eventually move away from traditional and centralized data centers. The company’s innovation is to place servers directly in residential homes and recycle the energy that dissipates from these servers into heating water. This process results in a reduced heating bill for homeowners, while removing the cost of setting up a traditional data center.

Moving servers to households saves 2 tonnes of CO2 per household per year, as well as the overhead cost of building a data center.

Nerdalize owns servers called ‘CloudBoxes’ that are installed in households all across the Netherlands. Dockerized computations are distributed to multiple CloudBoxes to run jobs for an impressive 40% of the cost of centralized cloud providers.

Powering the First Decentralized Marketplace for Computing Resources

iExec’s V2 release planned for May 29 presents a new paradigm for cloud computing: a global and open market where computing power is traded like a commodity. The marketplace offers an easy-to-use interface through which applications and users in need of computing power can meet providers able to answer their demand at the best rate possible.

Nerdalize has joined the initial group of private workers in the iExec marketplace. By combining efforts, our two companies are not just leaving a positive mark on the environment, but on society as well by making cloud computing an affordable commodity for everyone.

By not having to invest in building and maintaining expensive data centers, iExec and Nerdalize can provide more affordable cloud computing offers. This in turn allows developers to innovate more easily in the compute-intensive fields of artificial intelligence, IoT, scientific research or big data, therefore radically enhancing our existence in unprecedented ways.

About iExec

iExec is developing the first blockchain-based decentralized cloud marketplace. This marketplace will allow developers and users in need of computing power to meet cloud providers willing to answer their demand. iExec The network supports the most compute-intensive decentralized applications in the fields of AI, big data, fintech, cryptography or 3D rendering.

About Nerdalize

Nerdalize is building a different cloud. Instead of constructing huge data centers, the company is distributing its servers over homes. Homeowners use the residual heat for hot showers and to warm their house, without needing to build new infrastructures. Nerdalize enables users to scale up computations without wasting CO2 or money.

Dutch company Nerdalize utilises server-heat in innovative heating system

From August onwards the first Dutch households can enjoy a free shower, warmed up by the heat of computer servers. For Nerdalize, this is just the first step in their mission to provide free server-heat to everyone in the Netherlands. They’ve developed a heating system, fed by the residual heat of computer servers, which can save households around 300 euros a year on their heating bills and significantly cuts back on CO2 emissions. In datacenters this residual heat needs to be cooled away, leading to high energy usage. Through the proceeds of a crowdfunding campaign, in which more than 200 people have invested so far, Nerdalize wants to equip the first 42 households with their heating system.

In 2015 Nerdalize ran a test with Eneco, a large Dutch utility, amongst 5 households. Servers were placed in houses for a few months and the server-heat was directly transformed into usable heat via a radiator. This means Nerdalize doesn’t waste energy on cooling servers. Instead, the system uses the energy for the servers twice: once to compute and once to heat water. In the new version, the servers are connected to the central heating system. This way, the heat can be utilised throughout the year for hot water. This setup saves money for households, but also for companies and researchers. As Nerdalize does not need to build an expensive datacenter, companies and researchers can compute for 50% lower costs!

If Boaz Leupe, co-founder of Nerdalize, has his way, data is on the verge of becoming a lot greener. And not a minute too soon: already datacenters emit more CO2 than the global airline industry.

So far, 3500 people have signaled their interest in the heating system and Nerdalize is kicking off to provide the first 42 households with free server-heat. Leupe has already raised €250,000 via the crowdfunding platform Symbid, but now hopes to raise €500,000 in investment. “If we reach our target amount in a month, we can start equipping the first houses with our server-heater from August onwards!” says Boaz Leupe.

Nerdalize’ crowdfunding campaign will run until the end of June.

The installation of a server heater, the Eneco eRadiator, in the living rooms of five families at different locations in the Netherlands this month, marks the start of an exclusive field test. The test is in line with Eneco’s strategy to develop into an energy partner of its customers by introducing innovative sustainable services.

Computer servers that perform calculations generate a lot of heat. By installing these servers in people’s homes instead of centralised large data centres, the generated heat can be used to heat these homes at no cost. The purpose of the test is to collect information on customer experience and to identify possible areas of improvement of the eRadiator.

This is the first time the design radiator with built-in server is installed in ordinary households. The servers shall perform complex calculations for a variety of companies and knowledge institutes, such as new medicine-related research for Leiden University Medical Centre.The Eneco eRadiator was developed by Nerdalize, a company that was founded in 2013 by the three initiators of the idea with the aim to further develop the server heater concept. Nerdalize is located at YES!Delft, Europe’s largest tech-incubator. Eneco believes that the eRadiator offers a range of possibilities and has acquired an interest in the start-up.

A study carried out in cooperation with the Leiden Institute of Advanced Computing Science shows that companies and institutions that require a lot of processing power can reduce their costs in the area of accommodation and cooling of datacentres by 30 to 55% with the concept developed by Nerdalize. There are also environmental benefits, because the same energy is used for two different purposes: computation and heating.

It will take at the least to the end of the year to complete the field test. Eneco and Nerdalize will use the results to determine if and how the eRadiator can be made available to a larger number of customers.
